Release 2.2.16
* New UDIM texture name patterns recognized: `%(UDIM)d` is the Houdini
convention, and `_u##v##` is for Animal Logic's internal renderer.
* When doing color space transforms on images with > 4 channels -- the
additional channels are now copied unaltered, rather than leaving them
black.
* FFMpeg: fix some encodings that didn't correctly recognize that they were
more than 8 bits, or had alpha.
* farmhash.h: Clean up all non-namespaced preprocessor symbols that are set
by this header and may pollute the caller's symbols.
* Fix crashes on M1 (ARM) based Mac.
* Bug fix: avid divide-by-0 error computing chunk size for invalid image
sizes.
* `make_texture` (and `maketx` and `oiiotool -otex`) no longer crash if you
try to make a texture out of a "deep" image; instead it will return an
error message.
* filesystem.h: Improve exception safety in Filesystem directory iteration.
* Build: Improve finding of OpenJPEG.
* Build: Support for building OIIO with gcc 11.
* Build: Fixes to accommodate Imath 3.1 upcoming changes.
* Build: Finding FFMpeg now correctly detects the version.
* Build: clang + C++17 + LibRaw < 0.20 are mutually incompatible. Detect
this combination and warn / disable libraw under those conditions.
* Build: Fix CMake behavior for `REQUIRED_DEPS` due to a typo.
* Build: Fixes for detecting and using Ptex, among other things got the
version wrong.
* Testing: If a feature is disabled, skip its tests rather than reporting
them as broken.
* CI: Test the combination of clang and C++17.

Release 2.2.15.1 (3 Jun 2021) -- compared to 2.2.15.0
-----------------------------------------------------
* Fix crash / misbehavior in ustring internals on Apple M1 ARM.
Release 2.2.15 (1 Jun 2021) -- compared to 2.2.14
--------------------------------------------------
* BMP improvements: now support reading rle-compressed BMP files; writing
single channel grayscale images now save as 8bpp palette images intead of
24bpp; and reading 8bpp where all palette entries have R==G==B looks like
a 1-channel grayscale instead of 3-channel RGB.
* Bug: IBA::render_text did not properly account for alpha of the draw
color.
* Bug: Fix runaway parsing time for pathological XMP metadata.
* Bug: Fixed a crash is ImageCacheFile::read_unmipped when sampling
* Fix exported cmake config files, which could fail if Imath and OpenEXR
weren't the at the same version number.
* Build: Modernize cmake to use targets for PNG and ZLIB.
* Build: Fix to accommodate upcoming OpenColorIO 2.1 deprecation of
parseColorSpaceFromString.
* Build: Changes to make it build against TBB 2021.
* Dev: Add Strutil functions: find, rfind, ifind, irfind.
non-zero-base channels.
Release 2.2.14 (1 May 2021) -- compared to 2.2.13
--------------------------------------------------
* JPEG: Improve readin of files with mildly corrupted headers.
* TIFF: Support IOProxy for input.
* BMP: Improve performance by eliminating wasteful per-scanline allocation
and needless data copying.
* Build/CI: Fix all the build_*.bash scripts to not use cmake --config flag,
which was harmlessly ignored but is flagged as an error for CMake 3.20.
* Build: More fixes related to supporting a wide range of OpenEXR versions,
and making our exported cmake configs correctly transmit dependencies on
OpenEXR include paths.
* ImageBufAlgo::fillholes_pushpull: added logic to correctly set the spec's
alpha_channel field when generating sub-images.
* Python: MakeTxBumpWithSlopes enum value had been inadvertently omitted
from the Python bindings.
Release 2.2.13 (1 Apr 2021) -- compared to 2.2.12
--------------------------------------------------
* Get ready for upcoming Imath/OpenEXR 3.0 release.
* GIF: Fix error checking for non-existant GIF files.
* Fix crash related to ImageBuf:set_write_format() when used in conjunction
with a file format that doesn't support per-channel data types.
* Make RAW files handle Unicode filenames on Windows.
* Make sure OIIO builds cleanly with C++20.
* BMP: Several bug fixes when reading an older (V1) variety of BMP files.
* Targa: fix reading tga files with 0-sized thumbnails.
* TIFF: fix reading of certain tiled TIFF files with the vertical image size
is not a whole multiple of the tile size.
* Avoid OpenColorIO v2 exception when color-conversion of single points (we
didn't pass a correct stride, thinking that stride isn't used for a single
point).
* make_texture: When outputting to a 'half' data format file, clamp filtered
values to the half range so large values don't inadvertently get converted
to half 'infinite' values.
* Improvements to ustring internals to ensure that no two ustrings ever end
up with the same hash() value.
* Fixes for compiler errors when compiling farmhash.h using C++11 mode with
newer gcc (6+).
Release 2.2.12 (1 Mar 2021) -- compared to 2.2.11
--------------------------------------------------
* Bug fix: Improve parsing of XMP records in metadata: more correct handling
of lists/sequences, better inference of types that look like int or float
(rather than forcing unknown fields into strings), fixed bugs in parsing
rational values.
* Bug fix: Fix loading PSB files with cinf tags.
* Build: Improvements to building or linking static libraries.
* Build: Change default STOP_ON_WARNING to OFF for release branches
(including this one) so that small change in compiler warnings after our
release don't break anybody's builds. (Though we still stop on warnings
for CI builds).
* Build: More clear warnings about using OpenVDB 8+ when building for C++11,
because OpenVDB 8 requires C++14 or higher.
* Build: The pkgconfig OpenImageIO.pc was specifying the include path
incorrectly.
* Build: More gracefully handle building against a custom Imath/OpenEXR even
when another exists in the system area.
* Build: Minor fixes to build cleanly against the upcoming Imath 3.0.
* Dev: hash.h: Make many of the hash functions constexpr.
* Dev: Better unit tests to verify correctness and stability over time of
the hash functions.
* Dev: unordered_map_concurrent.h: New methods find_or_insert, nobin_mask().
* CI: Speed up CI builds by not building OpenEXR example programes.
* CI: Speed up CI by using GitHub 'cache' actions + ccache.
* CI: Separate stages (setup, deps, build, test) into separate GHA "steps"
for better logging and understanding of the timing and performance.
* CI: Now actively testing libheif in Linux CI.
* CI: Remove the last vestiges of Travis-CI, which we no longer use.
* CI: For failed tests, add CMake cache and log part of the saved artifacts.
* PSA: Avoid libheif 1.10 on Mac, it is broken. Libheif 1.11 is fine.
Release 2.2.11.1 (1 Feb 2021) -- compared to 2.2.11.0
-----------------------------------------------------
* Fix build break against Qt 5.15.2 (deprecated enum).
Release 2.2.11 (1 Feb 2021) -- compared to 2.2.10
--------------------------------------------------
* Enabled AVIF decoding of heic files (requires libheif >= 1.7 and for it
to have been built with an AV1 encoder/decoder).
* `oiiotool --help` now prints the OCIO version (where it prints the config
file and known color space).
* Bug fix: ImageBufAlgo::ociolook() and ociofiletransform() internally
reversed the order of their `inverse` and `unpremult` arguments, making it
hard to select the inverse transformation.
* Fix memory leak during decoding of some invalid Exif blocks.
* Build: No longer directly link against python libraries when unnecessary.
* Build: Better finding of OpenJpeg 2.4.
* Build: On Windows, fix some linkage problems by changing the pybind11
bindings to make a CMake "shared" library rather than "module". Sounds
wrong, but seems to work. We will reverse if this causes problems.
* Build: On Mac, libheif 1.10 is very broken. Don't use that version.
* Build: Fix build break against changes coming in future libtiff, where it
is changing from some libtiff-defined integer types to the equivalent
stdint.h types.
* Build: Some final touches to prepare for release of OpenColor 2.0.
* Build: Fixes to support the libraw 202101 snapshot (their in-progress
0.21.0).
* CI: Got Windows CI fully working, bit by bit.
* Dev: Some internal rearrangement of span.h and string_view.h (that should
not break source or ABI compatibility). `std::size()` and `std::ssize()`
should work with OIIO::span and OIIO::string_view now.
* Dev: ustring internals now have a way to ask for the list of ustrings
whose hashses collided.
* Dev: New Filesystem::generic_filepath() returnss a filepath in generic
format (not OS specific).
* Dev: ArgParse::abort() lets the response to a command line argument signal
that no further arguments should be parsed.
* Dev: In oiioversion.h, added macros `OIIO_VERSION_GREATER_EQUAL` and
`OIIO_VERSION_LESS`.
* Dev: In platform.h, added macro OIIO_INLINE_CONSTEXPR, which is equivalent
to `inline constexpr` for C++17, but just constexpr for C++ <= 14.

Release 2.2 (1 Sept 2020) -- compared to 2.1
----------------------------------------------
New minimum dependencies:
* pybind11 >= 2.4.2
* openjpeg >= 2.0 (if JPEG-2000 support is desired) #2555 (2.2.2)
New major features and public API changes:
* Improved IOProxy support:
- ImageInput and ImageOutput now have direct API level support for IOProxy
in their `open()` and `create()` calls, as well as a new `set_ioproxy()`
method in these classes. #2434 (2.2.0)
- ImageBuf can now specify a proxy upon construction for reading, and for
writing via a `set_write_ioproxy()` method that applies to subsequent
`write` call. #2477 (2.2.1).
- DPX input now supports IOProxy. #2659 #2665 (2.2.5)
- ImageCache (and ImageBuf backed by ImageCache) entries that use IOProxy
are careful not to fully "close" their proxies when trying to reclaim
space in the file cache (that would be bad, since the proxy can't be
re-opened). #2666 (2.2.5)
* Improved support for multi-subimage files:
- oiiotool: Nearly all operations now allow an optional `:subimages=...`
modifier that restricts the operation to be performed on only a subset
of named or indexed subimages. See docs for details. #2582
- Python `ImageBuf.write()` variety added that takes an open
`ImageOutput`. This is the key to writing a multi-subimage file (such
as a multi-part OpenEXR) using the Python ImageBuf interface. #2640
(2.2.4)
- Fixes to `--croptofull` and `-o` with multi-subimages. #2684 (2.2.6)
* Python bindings:
- Python bindings have been added for missing ParamValue constructors.
We previously exposed the PV constructors from just a plain int, float,
or string, but there wasn't an easy way to construct from arbitrary
data like there is in C++. Now there is. #2417 (2.2.0)
- `ParamValueList.attribute()`, when being passed attributes containing
multiple values, now can have those values passed as Python lists and
numpy arrays (previously they had to be tuples). #2437 (2.1.11/2.2.0)
- `ImageBufAlgo.color_range_check()` is now available to the Python
bindings (was previously only C++). #2602 (2.2.3)
- New variety of `ImageBuf.write()` that takes an open `ImageOutput`.
This is the key to writing a multi-subimage file (such as a multi-part
OpenEXR) using the Python ImageBuf interface. #2640 (2.2.4)
* ImageBuf:
- Easier direct use of IOProxy with ImageBuf: constructor and reset()
for file-reading ImageBuf now take an optional `IProxy*` parameter,
and a new `set_write_ioproxy()` method can supply an IOProxy for
subsequent `write()`. #2477 (2.2.1)
- Add `ImageBuf::setpixel()` methods that use cspan instead of ptr/len.
#2443 (2.1.10/2.2.0)
- Add "missing" `reset()` varieties so that every IB constructor has a
corresponding `reset()` with the same parameters and vice versa. #2460
* ImageBufAlgo:
- New `repremult()` is like premult, but will not premult when alpha is
zero. #2447 (2.2.0)
- New `max()` and `min()` functions take the pixel-by-pixel maximum
or minimum of two images. #2470 (2.2.1)
* ColorConfig: add OCIO "role" accessors. #2548
* Low-res I/O of images to terminals that support full color and Unicode
characters. Just output to a file ending in ".term", and it will convert
(on certain terminals) to an image displayed directly in the terminal.
#2631 (2.2.4)
Try:
`oiiotool myfile.exr -o out.term`
Performance improvements:
* Greatly improved TextureSystem/ImageCache performance in highly threaded
situations where access to the cache was a main bottlenecks. In renders of
scenes with lots of texture access, with dozens of threads all contending
for the cache, we are seeing some cases of 30-40% reduction in total
render time. In scenes that are less texture-bottlenecked, or that don't
use huge numbers of threads, the improvement is more modest. #2433 (2.2.0)
Fixes and feature enhancements:
* oiiotool:
- Intelligible error messages (rather than crashes) if you attempt to
create an image too big to fit in memory. #2414 (2.2.0)
- `--create` and `--proxy` take an additional optional modifier:
`:type=name` that specifies the type of buffer to be created (the
default, as usual, is to create an internal float-based buffer). #2414
(2.2.0)
- `-o` optional argument `:type=name` is a new (and preferred) synonym
for what used to be `:datatype=`. #2414 (2.2.0)
- `--autotrim` now correctly trims to the union of the nonzero regions
of all subimages, instead of incorrectly trimming all subimages to the
nonzero region of the first subimage. #2497 (2.2.1.2)
- `--subimage` now has an optional `:delete=1` modifier that causes the
operation to delete one named or indexed subimage (versus the default
behavior of extracing one subimage and deleting the others). #2575
(2.2.3)
- The list of dependent libraries (part of `oiiotool --help`) now
correctly reports the OpenEXR version. #2604 (2.2.3)
- Fix: `--eraseattrib` did not correctly apply to all subimages when
`-a` or `:allsubimages=1` were used. #2632 (2.2.4)
* ImageBuf / ImageBufAlgo:
- Huge ImageBuf allocation failures (more than available RAM) now are
caught and treated as an ImageBuf error, rather than crashing with an
uncaught exception. #2414 (2.2.0)
- ImageBuf constructors that are passed an ImageSpec (for creating an
allocated writable IB or "wrapping" a user buffer) now check that the
spec passed has enough information to know the size of the buffer
(i.e., it will be recognized as an error if the width, height, depth,
channels, or data type have not been set validly). #2460
- Fix: `ImageBuf::getchannel()` did not honor its `wrap` parameter.
#2465 (2.2.1/2.1.12)
- Fix: `IBA::reorient()` and `IBA::computePixelHashSHA1()` did not honor
their `nthreads` parameter. #2465 (2.2.1/2.1.12)
- `resample()` has been modified to more closely match `resize` by using
clamp wrap mode to avoid a black fade at the outer edge of the
resampled area. #2481
- Fix: `ImageBuf::get_pixels()` did not honor the stride parameters.
#2487. (2.1.12/2.2.1)
- Fix `resize()` to avoid a crash / stack overflow in certain cases of
very big images and very large filter kernels. #2643 (2.2.4)
- Minor improvements to ImageBuf error formatting. #2653 (2.2.5)
* ImageCache / TextureSystem / maketx:
- New IC/TS attribute "trust_file_extensions", if nonzero, is a promise
that all files can be counted on for their formats to match their
extensions, which eliminates some redundant opens and format checks
in the IC/TS and can reduce needless network/filesystem work. Use with
caution! #2421 (2.2.0)
- texture3d() fixed some cases where derivative results were not
correctly copied to the outputs. #2475 (2.2.1)
- `maketx`/`IBA::make_texture`: better error detection and messages when
using "overscan" textures with formats that can't support it properly.
(Punchline: only OpenEXR textures can do it.) #2521 (2.2.0)
- Fix possible redundant tile reads in multithread situations (harmless,
but makes for redundant I/O). #2557 (2.2.2)
* Python:
- Fixed a bug that lost certain string arguments, especially when passing
a TypeDesc as its string equivalent. #2587 (2.1.16/2.2.3)
- Fixed broken bindings of ImageSpec.erase_attribute. #2654
(2.1.19/2.2.6)
- Fix missing ImageInput.read_image(). #2677 (2.1.19/2.2.6)
* Exif read: guard better against out of range offsets, fixes crashes when
reading jpeg files with malformed exif blocks. #2429 (2.1.10/2.2.0)
* Fix: `ImageSpec::erase_attribute()` did not honor its `searchtype`
parameter. #2465 (2.2.1/2.1.12)
* Fix: Some ColorProcessor::apply() methods were not using their `chanstride`
parameters correctly. #2475 (2.1.12)
* Fix: iinfo return code now properly indicates failures for files that
can't be opened. #2511 (2.2.2/2.1.13)
* DPX:
- IOProxy reading is now supported. #2659 (2.2.5)
- DPX: Add support for reading DPX files from IOProxy (such as from a
memory buffer). #2659 #2665 (2.1.19/2.2.6)
* HDR files:
- Improve performance when reading HDR files out of order (when combined
with ImageCache, observed to speed up out-of-order HDR reading by 18x).
#2662 (2.2.5)
* JPEG:
- Fix resolution unit metadata that was not properly set in JPEG output.
#2516 (2.2.2/2.1.13)
- Fix loss of 'config' info upon close/reopen. #2549 (2.2.2)
* OpenEXR:
- Add support for reading and writing float vector metadata. #2459 #2486
- Fix bug in the channel sorting order when channels are "X" and
"Y" (was reversing the order by confusing "Y" for "luminance"). #2595
(2.1.16/2.2.3)
- We no longer automatically rename the "worldToNDC" attribute to
"worldtoscreen" and vice versa. #2609 (2.2.4)
* PNG:
- Fix loss of 'config' info upon close/reopen. #2549 (2.2.2)
- Add output configuration hint "png:filter" to control PNG filter
options. #2650 (2.2.5)
- Improved propagation of PNG write errors. #2655 (2.2.5)
- Tell libpng to turn off sRGB profile check, which has a known problem of
false positives. #2655 (2.2.5)
- New output option "png:filter" allows control of the PNG filter
options. #2650 (2.1.19/2.2.6)
* Raw images:
- Support for new Canon .cr3 file, but only if you build against
libraw >= 0.20.0 developer snapshot. #2484 (2.2.1) #2613 (2.2.4)
- RAW input: set the "raw:flip" attribute if the underlying libraw did a
reorientation. #2572 (2.1.15/2.2.3)
- Avoid errors (in libraw) that resulted from multiple threads opening
raw files at the same time. #2633 (2.2.4)
* RLA:
- Additional sanity checks and error checks/messages for detecting files
that might be first mistaken for RLA files, but actually are not.
#2600 (2.2.3)
* TIFF:
- Internal improvements to handling metadata retrieval for certain
unusual tags. #2504 (2.2.2/2.1.13)
- Fix subtle bug when reading Exif directory in the header. #2540
(2.2.2)
* Video files:
- Fix possible infinite loop in the FFMpeg-based reader. #2576
(2.1.15/2.2.3)
Developer goodies / internals:
* argparse.h:
- Complete overhaul of ArgParse to make it more like Python argparse.
Please read the extensive comments in argparse.h for documentation.
For now, the old ArgParse interface still works, but is considered
deprecated. #2531 (2.2.2) #2618 #2622 (2.2.4)
* attrdelegate.h:
- New `as_vec<>` method returns the whole attribute as a std::vector.
#2528 (2.2.2)
* filesystem.h:
- Catch previously uncaught exceptions that could happen in certain
Filesystem utility calls. #2522 (2.2.2/2.1.13)
- New `write_text_file()` convenience function for opening, writing, and
closing a text file all in one step. #2597 (2.2.3)
* fmath.h:
- clamp() is 2x faster. #2491 (2.1.12/2.2.2)
- Very minor fix to OIIO::clamp(), shouldn't affect normal use with
floats at all, but fixed a subtle quasi-bug in OSL. #2594 (2.1.15/2.2.3)
- madd() is improved especially on platforms without fma hardware
#2492 (2.1.12/2.2.2)
- Perf improvements to `fast_sin`, `fast_cos` #2495 (2.1.12/2.2.2)
- New `safe_fmod()` is faster than std::fmod. #2495 (2.1.12/2.2.2)
- New `fast_neg` is faster than simple negation in many cases, if you
don't care that -(0.0) is 0.0 (rather than a true -0.0). #2495
(2.1.12/2.2.2)
- Add vint4, vint8, and vint16 versions of `clamp()`. #2617 (2.2.4)
* oiioversion.h:
- Fix typo that left the OIIO_VERSION_RELEASE_TYPE symbol undefined.
#2616 (2.2.4/2.1.16)
- Add new `OIIO_MAKE_VERSION(maj,min,patch)` macro that constructs the
proper single integer code for a release version. #2641 (2.2.4/2.1.17)
* paramlist.h:
- New `ParamValueList::find_pv()` method that is similar to `find()` but
returns a pointer rather than an iterator and nullptr if the attribute
is not found. #2527 (2.2.2/2.1.13)
- Add `get_indexed()` method to ParamValueList and AttrDelegate. #2526
(2.2.2/2.1.13)
* platform.h:
- `OIIO_PRETTY_FUNCTION` definition is more robust for weird compilers
(will fall back to `__FUNCTION__` if all else fails). #2413 (2.2.0)
- `OIIO_ALIGN` definition is more robust, will fall back to C++11
alignas when not a compiler with special declspecs (instead of being
a compile time error!). #2412 (2.2.0)
- A variety of `OIIO_PRAGMA_...` macros have been added to help deal
with compiler-specific pragmas. #2467 (2.2.1)
* simd.h:
- vfloat3 has added a `normalize()`, `length()`, and `length2()`
methods, to more closely match the syntax of Imath::Vec3f. #2437
(2.1.11/2.2.0)
- fix errors in vbool == and !=. #2463 (2.1.11/2.2.1)
- Add float3 versions of abs, sign, ceil, floor, and round (they already
existed for float4, float8, float16, but not float4). #2612 (2.2.4)
- Improved support for ARM NEON SIMD (caveat: this is still not well
tested). #2614 (2.2.4)
- Improve performance for many float8/int8 functions and operators when
running on only 4-wide hardware, by using two 4-wide instructions
instead of reverting to scalar. #2621
* span.h:
- Allow the constructor from `std::vector` to allow vectors with custom
allocators. #2533 (2.2.2)
* strutil.h / ustring.h:
- New `Strutil::concat()` and `ustring::concat()` concatenate two
strings, more efficiently than `sprintf("%s%s")` by avoiding any
unnecessary copies or temporary heap allocations. #2478 (2.2.1)
- Strutil::upper() and lower() return all-upper and all-lowercase
versions of a string (like `to_lower` and `to_upper`, but not in-place
modifications of the existing string). #2525 (2.2.2/2.1.13)
- `Strutil::repeat()` has been internally rewritten to more efficient by
avoiding any unnecessary copies or temporary heap allocations. #2478
(2.2.1)
* typedesc.h:
- TypeDesc has additional helpers of constexpr values TypeFloat2,
TypeVector2, TypeVector4, TypeVector2i, TypePointer. #2592 (2.1.16/2.2.3)
* unordered_map_concurrent.h:
- Fix missing decrement of `size()` after `erase()`. #2624 (2.2.4)
* More reshuffling of printf-style vs fmt-style string formatting. #2424
(2.2.0) #2649 (2.2.4)
* Internals: changed a lot of assertions to only happen in debug build mode,
and changed a lot that happen in release builds to only print the error
but not force a termination. #2435 (2.1.11/2.2.0)
* Internals: Replaced most uses of `boost::thread_specific_ptr` with C++11
`thread_local`. #2431 (2.2.0)
* oiiotool: Big overhaul and simplification of internals. #2586 #2589 (2.2.3)
Build/test system improvements and platform ports:
* CMake build system and scripts:
- New non-default CMake build flag `EXTRA_WARNINGS`, when turned on, will
cause gcc and clang to compile with -Wextra. This identified many new
warnings (mostly about unused parameters) and fixes were applied in
#2464, #2465, #2471, #2475, #2476. (2.2.1)
- FindOpenColorIO.cmake now correctly discerns the OCIO version (2.2.1),
and now sets up a true imported target. #2529 (2.2.2)
- FindOpenEXR.cmake has better detection of debug openexr libraries.
#2505 (2.2.2/2.1.13)
- Additional cmake controls to customize required vs optional
dependencies: `REQUIRED_DEPS` (list of dependencies normally optional
that should be treated as required) and `OPTIONAL_DEPS` (list of
dependencies normally required that should be optional). The main use
case is to force certain optional deps to be required for your studio,
to be sure that missing deps are a full build break, and not a
successful build that silently lacks features you need. #2507
(2.2.2/2.1.13)
- Fix exported cmake config file, it was not ensuring that the Imath
headers properly ended up in the config include path. #2515
(2.2.2/2.1.13)
- Change all CMake references to PACKAGE_FOUND to Package_Found (or
whatever capitalization matches the actual package name). #2569 (2.2.2)
- The exported CMake config files now set cmake variable
`OpenImageIO_PLUGIN_SEARCH_PATH` #2584 (2.1.16/2.2.3)
- Improved hints printed about missing dependencies. #2682 (2.2.6)
* Dependency version support:
- Pybind11 is no longer auto-downloaded. It is assumed to be
pre-installed. A script `src/build-scripts/build_pybind11.bash` is
provided for convenience if you lack a system install. #2503 (2.2.2)
Bump the minimum pybind11 version that we accept, to 2.4.2 #2453,
and add fixes to allow support of pybind11 2.5. #2637 (2.2.4)
- fmt libray: Un-embed fmt headers. If they are not found on the system
at build time, they will be auto-downloaded. #2439 (2.2.0)
- Support for building against libraw 0.20. #2484 (2.2.1) #2580 (2.2.3)
- Build properly against OpenColorIO's current master (which is the
in-progress work on OCIO v2). #2530 (2.2.2)
- Fix static boost to not overlink on Windows. #2537 (2.2.2)
- Fix build breaks against TOT libtiff master, which had `#define`
clashes with our GPSTag enum values. #2539 (2.2.2)
- Ensure compatibility and clean builds with clang 10. #2518 (2.2.2/2.1.3)
- Support verified for gcc 10, added to CI tests. #2590 (2.2.3)
- Support for Qt 5.15. #2605 (2.2.3)
- Fixes to support OpenColorIO 2.0. #2636 (2.2.4)
- Build against more recent versions of fmtlib. #2639 (2.2.4)
- Included scripts to download and build libtiff #2543 (2.1.13/2.2.2),
PugiXML #2648 (2.2.4), zlib, libpng, libjpeg-turbo. #2663 (2.2.5)
- Minor fixes for libheif 1.8. #2685 (2.2.6)
- Add a build_libtiff.bash script to make it easy to build the libtiff
dependency. #2543 (2.1.13/2.2.2)
- "tinyformat" is no longer used, even optionally. We have switched
entirely to fmtlib, which is more similar to the upcoming C++20
std::format. #2647 (2.2.4)
* Testing and Continuous integration (CI) systems:
- Mostly retire TravisCI for ordinary Linux x64 and Mac builds, now we
rely on GitHub Actions CI. Nightly test added. Use ASWF docker images
to test exactly against VFX Platform 2019 and 2020 configurations.
#2563 (2.2.2) #2579 (2.2.3)
- Add Travis test for arm64 (aka aarch64) builds. This is still a work
in progress, and not all testsuite tests pass. #2634 (2.2.4)
- Our CI tests now have a "bleeding edge" matrix entry that tests against
the current TOT master build of libtiff, openexr (#2549), and pybind11
(#2556). (2.2.2)
- GitHub CI tests, when they fail, leave behind an "artifact" tar file
containing the output of the tests, so that they can be easily
downloaded and inspected (or used to create new reference output).
#2606 (2.2.4)
- CI Mac tests switch to Python 3.8. (2.2.4)
- Windows CI switched from using Vcpkg to building its own dependencies.
#2663 (2.2.5)
- Testing of TGA now assumes the test images are in the oiio-images
project, not separately downloaded (the download location disappeared
from the net). #2512 (2.2.2)
- Beef up OpenEXR compliance tests, many more examples from
openexr-images, including many corrupted image failure cases. #2607
(2.2.4)
* Progress on support for using Conan for dependency installation. This is
experimental, it can't yet build all dependencies. Work in progress.
#2461 (2.2.1)
* The version of gif.h that we embed for GIF output has been updated.
#2466 (2.2.1)
* The `farmhash` functions have been cleaned up to be more careful that none
of their internal symbols are left visible to the linker. #2473 (2.2.1)
* Clarification about .so name versioning: In supported releases, .so
contains major.minor, but in master (where ABI is not guaranteed stable,
we name major.minor.patch). #2488 (2.2.1)
* Protect against certain compiler preprocessor errors for user programs
that include strutil.h but also include `fmt` on its own. #2498.
(2.1.12/2.2.2)
* Build: All the `build_foo.bash` helper scripts now use `set -ex` to ensure
that if any individual commands in the script fails, the whole thing will
exit with a failure. #2520 (2.2.2/2.1.3)
* Fix compiler warning about incorrect extra braces. #2554 (2.2.2)
* All build-scripts bash scripts now use /usr/bin/env to find bash. #2558
(2.2.2)
* Avoid possible link errors by fully hiding IBA functions taking IplImage
parameters, when no OpenCV headers are encountered. #2568 (2.2.2)
* In (obsolete) FindOpenImageIO.cmake, avoid CMake warnings by changing
the name `OPENIMAGEIO_FOUND` -> `OpenImageIO_FOUND`. #2578 (2.2.3)
* Moved headers that are not part of OIIO's supported public API, but that
still must be installed to be transitively included, do a "detail"
subdirectory. #2648 (2.2.4)
* Fix many Mingw compiler warnings. #2657 (2.1.19/2.2.5)
* Windows: Improve Strutil::get_rest_arguments() handling of long path
syntax (`"\\?\"` style). #2661 (2.1.19/2.2.6)
* Fix compilation error with armv7 + x86. #2660 (2.2.6)
Notable documentation changes:
* Many enhancements in the ImageBuf chapter. #2460 (2.1.11/2.2.0)
* The `LICENSE-THIRD-PARTY.md` file has been reorganized to be clearer,
grouping parts with identical licenses. #2469 (2.2.1) And renamed to
"THIRD-PARTY.md" to avoid confusing GitHub's reporting of the project's
license. (2.2.6)
* Many fixes to the new readthedocs documentation, especially fixes to
section cross-references and links.
* Improved INSTALL instructions. (2.2.2/2.1.13)
* Fix a variety of breaks on ReadTheDocs. #2581
* Improve the way we discuss optional modifiers.
* Document the PNG output controls for compression level. #2642 (2.2.4)
* Lots of spell check / typo fixes in docs and comments. #2678 (2.2.6)
* INSTALL.md: remove misleading old Windows build instructions. #2679 (2.2.6)
* New file .git-blame-ignore-revs lists the hashes of commits that only
performed bulk reformatting, so that they don't misattribute authorship
or modification date. Everybody do this in your local repo:
`git config blame.ignoreRevsFile .git-blame-ignore-revs`
#2683 (2.2.6)
Release 2.1.20 (1 Oct 2020) -- compared to 2.1.19

the split should return no pieces. #2712
Release 2.1.19 (1 Sep 2020) -- compared to 2.1.18
-------------------------------------------------
* DPX: Add support for reading DPX files from IOProxy (such as from a memory
buffer). #2659 #2665
* PNG: New output option "png:filter" allows control of the PNG filter
options. #2650
* Python: Fix binding of ImageSpec.erase_attribute. #2654
* Python: Fix missing ImageInput.read_image(). #2677

syntax (`"\\?\"` style). #2661
* MinGW: Fix a variety of compiler warnings on this platform. #2657
* Fix build on Elbrus 2000 architecture. #2671
Release 2.1.18 (1 Aug 2020) -- compared to 2.1.17
-------------------------------------------------
* Python `ImageBuf.write()` added a variety that takes an open ImageOutput.
This is the key to writing multi-subimage files from Python. #2640
* `oiiotool --eraseattrib` fixed: was not applying to all subimages. #2632
* RAW: Improve thread safety when more than one thread might be opening
different raw files at the same time. #2633
* unordered_map_concurrent fixed a missing size decrement upon erase(). #2624
* Fixes to support certain recent pybind11 changes. #2637
* Fixes to support OpenColorIO v2. #2636
* Fixes to support more recent fmtlib versions. #2639
* PNG: document the "png:compressionLevel" output hint. #2642
* In oiioversion.h, add a `OIIO_MAKE_VERSION` macro that constructs the
integer code for a particular major/minor/patch release. #2641
* 2.1.18.1: Fix version number which for 2.1.18.0 unfortunately still
said it was 2.1.17.
Release 2.1.17 (1 Jul 2020) -- compared to 2.1.16
-------------------------------------------------
* Build: Use the discovered python binary name, to address the Fedora
restriction that you must use "python2" or "python3" by name. #2598
* Docs: ImageBufAlgo::nonzero_region had been inadvertently left out of the
Python chapter.
* Improve RLA reader's ability to detect corrupt or non-RLA files, which
fixes crashes you could get from trying to read non-image files. #2600
* Support for building against Qt 5.15. (Note: Qt support is only needed
for the "iv" viewer.) #2605
* Fixes to support LibRaw 0.20 (which is currently in beta3). Note that this
will make it incompatible with 0.20 beta1 and beta2, due to a fixed typo
of a struct field in one of the LibRaw's headers. #2613
* oiioversion.h: fix typo that left the OIIO_VERSION_RELEASE_TYPE symbol
undefined. #2616
Release 2.1.16 (1 Jun 2020) -- compared to 2.1.15
-------------------------------------------------
* OpenEXR: Fix bug in the channel sorting order when channels are "X" and
"Y" (was reversing the order by confusing "Y" for "luminance"). #2595
* Python: Fixed a bug that lost certain string arguments, especially when
passing a TypeDesc as its string equivalent. #2587
* fmath: Very minor fix to OIIO::clamp(), shouldn't affect normal use with
floats at all, but fixed a subtle quasi-bug in OSL. #2594
* TypeDesc has additional helpers of constexpr values TypeFloat2,
TypeVector2, TypeVector4, TypeVector2i, TypePointer. #2592
* Build: The exported CMake config files now set cmake variable
`OpenImageIO_PLUGIN_SEARCH_PATH` #2584
* Docs: improvements and fixes to broken page rendering.
Release 2.1.15 (11 May 2020) -- compared to 2.1.14
--------------------------------------------------
* RAW input: set the "raw:flip" attribute if the underlying libraw did a
reorientation. #2572
* Movie files: Fix possible infinite loop in the FFMpeg-based reader. #2576
* Fixes to allow building against the forthcoming LibRaw 0.20 release. #2484
* Documentation fixes. #2581
Release 2.1.14 (1 May 2020) -- compared to 2.1.13
-------------------------------------------------
* JPEG & PNG: Fix loss of 'config' hints upon close and reopen that could
happen in cases where scanlines were accessed out of order. #2549
* TIFF: Fix subtle bug when reading certain Exif directories in the header.
#2540
* Added OCIO role accessors to the ColorConfig class. #2548
* Improve error messages when overscan textures are not possible. #2521
* Build: fix problems when compiling against current libtiff master (symbol
clash on GPSTAG values). #2539
* Build: Fix static boost to not overlink. #2537.
* Fix some problems with the docs. #2541
* `AttrDelegate::as_vec<>` returns the whole attribute as a std::vector.
#2528
* Add a build_libtiff.bash script to make it easy to build the libtiff
dependency. #2543
Release 2.1.13 (1 Apr 2020) -- compared to 2.1.12
-------------------------------------------------
* Fix: iinfo return code now properly indicates failures for files that
can't be opened. #2511
* Fix: Catch previously uncaught exceptions that could happen in certain
Filesystem utility calls. #2522
* Fi: Some `span<>` methods involving `std::vector` now will work properly
with vectors that have custom allocators. #2533
* Fix: ParamValueList `add_or_replace()` was failing to "replace" if the new
attribute had a different type than the existing one. #2527
* Fix: Fix resolution unit metadata that was not properly set in JPEG output.
#2516
* Build: Additional cmake controls to customize required vs optional
dependencies -- `REQUIRED_DEPS` (list of dependencies normally optional
that should be treated as required) and `OPTIONAL_DEPS` (list of
dependencies normally required that should be optional). The main use case
is to force certain optional deps to be required for your studio, to be
sure that missing deps are a full build break, and not a successful build
that silently lacks features you need. #2507
* Build: Fix exported config file, it was not ensuring that the Imath
headers properly ended up in the config include path. #2515
* Build: Ensure compatibility and clean builds with clang 10. #2518
* Build: All the `build_foo.bash` helper scripts now use `set -ex` to ensure
that if any individual commands in the script fails, the whole thing will
exit with a failure. #2520
* Build correctly against the current master branch of OpenColorIO
(previously we were only testing and properly building against the 1.1
release). #2530
* Added Strutil::upper() and lower() functions. #2525
* ParamValueList enhancement: new `find_pv()` method that is similar to
`find()` but returns a pointer rather than an iterator and nullptr if the
attribute is not found. #2527
* Add `get_indexed()` method to ParamValueList and AttrDelegate. #2526
Release 2.1.12 (2 Mar 2020) -- compared to 2.1.11
-------------------------------------------------
* Fix: plugin.h getsym() didn't pass along its report_error param. #2465
* Fix: ImageBuf::getchannel() did not honor its wrap parameter. #2465
* Fix: ImageSpec::erase_attribute() did not honor its `searchtype` param. #2465
* Fix: IBA::reorient() and IBA::computePixelsHashSHA1() did not honor their
`nthreads` parameter. #2465.
* IBA::resample() now uses the clamp wrap mode to avoid black fringing and
match the behavior of resize(). #2481
* Fix: ImageBuf::get_pixels() did not honor the stride parameters. #2487.
* fmath.h perf improvements: clamp() is 2x faster; madd() is improved
especially on platforms without fma hardware; perf improvements in
`fast_sin`, `fast_cos`; new `safe_fmod` is faster than std::fmod, new
`fast_neg` is faster than simple negation in many cases, if you don't care
that -(0.0) is 0.0 (rather than a true -0.0). #2491 #2492 #2494
* strutil: New function: concat(). #2478
* Build: un-embed the 'fmt' headers, instead auto-download if not found.
#2439
* Build: Protect against certain compiler preprocessor errors for user
programs that include strutil.h but also include `fmt` on its own. #2498.
Release 2.1.11 (1 Feb 2020) -- compared to 2.1.10
-------------------------------------------------
* Python bindings for `ParamValueList.attribute()`, when being passed
attributes containing multiple values, now can have those values passed
as Python lists and numpy arrays (previously they had to be tuples).
#2437
* OpenEXR support is extended to handle float vector metadata. #2459
* Developer goody: simd.h vfloat3 has added a `normalize()`, `length()`,
and `length2()` methods, to more closely match the syntax of Imath::Vec3f.
#2437
* Internals: changed a lot of assertions to only happen in debug build mode,
and changed a lot that happen in release builds to only print the error
but not force a termination. #2435
* simd.h fix errors in vbool == and !=. #2463
* Make sure the embedded 'farmhash' implementation is completely hidden
behind proper namespaces. #2473
* Many docs fixes.
Release 2.1.10.1 (10 Jan 2019)
------------------------------
* Automatically detect the need to link against libatomic (fixes build on
some less common platforms, should not affect Windows, MacOS, or Linux on
x86/x86_64 users). #2450 #2455
* Fixes to unordered_map_concurrent.h that affect some users who it for
things other than OIIO per se (recent changes to the internals broke its
use for the default underlying std::unordered_map). #2454
* Bump the minimum pybind11 version that we auto-download, and also be sure
to auto-download if pybind11 is found on the system already but is not an
adequately new version. #2453
* If libsquish is found on the system at build time, use it, rather than
the "embedded" copy. This can improve build times of OIIO, and also helps
us comply with Debian packaging rules that forbid using embedded versions
of other Debian packages that can be used as simple dependencies. #2451
* Fixes to formatting of man page generation (resolves warnings on Debian
build process).
Release 2.1.10 (1 Jan 2020) -- compared to 2.1.9
--------------------------------------------------
* Suppress warnings with old libraw on earlier gcc versions. #2413
* Exif read: guard better against out of range offests, fixes crashes when
reading jpeg files with malformed exif blocks. #2429
* Python: add binding for missing ParamValue constructors. #2417
* oiiotool & ImageBuf better error messages (rather than mysterious crash)
for certain out of memory conditions. #2414
* oiiotool --create and --pattern take a new optional parameter:
`:type=name` that overrides the default behavior of allocating all
internal buffers as float. #2414
* Lots of typo fixes in docs, comments, and error messages. #2438
* Fix broken version in the built openimageio.pc PkgConfig file. #2441
* Fix typo in build script that caused it to fail to set the right symbol
definition when building static libs. #2442.
* More robust OIIO_PRETTY_FUNCTION definition. #2413
* Better fallback for OIIO_ALIGN, rely on C++11. #2412
* Docs: fix some II and IO chapter examples that used old open() API.
* Build: bump default version of pybind11 to 2.4.3. #2436
* Add ImageBuf::setpixel() methods that use cspan instead of ptr/len. #2443
* Fixes to cmake config generation. #2448
Release 2.1 (8 Dec 2019) -- compared to 2.0
----------------------------------------------
New minimum dependencies:
* CMake minimum is now 3.12. #2348 (2.1.5)
Major new features and performance improvements:
* Support for HEIC/HEIF images. HEIC is the still-image sibling of HEVC
(a.k.a. H.265), and compresses to about half the size of JPEG but with
higher visual quality. #2160 #2188 (2.1.0)
* oiiotool new commands: `-evaloff` `-evalon` `--metamerge` `--originoffset`
* ImageCache/TextureSystem improved perf of the tile and file caches under
heavy thread contention. In the context of a renderer, we have seen
improvements of around 7% in overall render time, averaged across a suite
of typical production scenes. #2314, #2316 (2.1.3) #2381 #2407 (2.1.8)
* Fix huge DPX reading performance regression. Technically this is a bug
fix that restores performance we once had, but it's a huge speedup.
#2333 (2.1.4)
* Reading individual frames from very-multi-image files (movie files) has
been greatly sped up (10x or more). #2345 (2.1.4)
Public API changes:
* ImageSpec new methods `getattribute()` and `getattributetype()`. #2204
(2.1.1)
* ImageSpec and ParamValueList now support operator `["name"]` as a way
to set and retrieve attributes. For example,
myimagespec["compression"] = "zip";
myimagespec["PixelAspectRatio"] = 1.0f;
int dither = myimagespec["oiio:dither"].get<int>();
std::string cs = myimagespec["colorspace"];
See the documentation about "Attribute Delegates" for more information,
or the new header `attrdelegate.h`. #2204 (2.1.1) #2297 (2.1.3)
* ImageSpec::find_attribute now will retrive "datawindow" and "displaywindow"
(type int[4] for images int[6] for volumes) giving the OpenEXR-like bounds
even though there is no such named metadata for OIIO (the results will
assembled from x, y, width, height, etc.). #2110 (2.1.0/2.0.4)
* "Compression" names (where applicable) can now have the quality appended
to the name (e.g., `"jpeg:85"`) instead of requiring quality to be passed
as a separate piece of metadata. #2111 (2.1.0/2.0.5)
* Python: define `__version__` for the module. #2096 (2.1.0/2.0.4)
* Python error reporting for `ImageOutput` and `ImageBuf.set_pixels`
involving transferring pixel arrays have changed from throwing exceptions
to reporting errors through the usual OIIO error return codes and queries.
#2127 (2.1.0/2.0.5)
* New shell environment variable `OPENIMAGEIO_OPTIONS` can now be used to
set global `OIIO::attribute()` settings upon startup (comma separated
name=value syntax). #2128 (2.1.0/2.0.5)
* ImageInput open-with-config new attribute `"missingcolor"` can supply
a value for missing tiles or scanlines in a file in lieu of treating it
as an error (for example, how OpenEXR allows missing tiles, or when reading
an incompletely-written image file). A new global `OIIO::attribute()`
setting (same name) also accomplishes the same thing for all files read.
Note that this is only advisory, and not all file times are able to do
this (OpenEXR is the main one of interest, so that works). #2129 (2.1.0/2.0.5)
* `ImageCache::invalidate()` and `TextureSystem::invalidate()` now take an
optional `force` parameter (default: true) that if false, will only
invalidate a file if it has been updated on disk since it was first opened.
#2133, #2166 (2.1.0/2.0.5)
* New filter name `"nuke-lanczos6"` matches the "lanczos6" filter from Nuke.
In reality, it's identical to our "lanczos3", but the name alias is
supposed to make it more clear which one to use to match Nuke, which uses
a different nomenclature (our "3" is radius, their "6" is full width).
#2136 (2.1.0/2.0.5)
* New helper functions in `typedesc.h`: `tostring()` converts nearly any
TypeDesc-described data to a readable string, `convert_type()` does data
type conversions as instructed by TypeDesc's. #2204 (2.1.1)
* ImageBuf:
- Construction from an ImageSpec now takes an optional `zero` parameter
that directly controls whether the new ImageBuf should have its buffer
zeroed out or left uninitialized. #2237 (2.1.2)
- `set_write_format()` method has a new flavor that takes a
`cspan<TypeDesc>` that can supply per-channel data types. #2239 (2.1.1)
* ColorConfig:
- Added `getColorSpaceFamilyByName()`, `getColorSpaceNames()`,
`getLookNames()`, `getDisplayNames()`, `getDefaultDisplayName()`,
`getViewNames()`, `getDefaultViewName()`. #2248 (2.1.2)
- Added Python bindings for ColorConfig. #2248 (2.1.2)
* Formal version numbers are now four parts: MAJOR.MINOR.PATCH.TWEAK.
#2313,#2319 (2.1.3)
* ImageInput now sets "oiio:subimages" attribute to an int representing the
number of subimages in a multi-image file -- if known from reading just
the header. A positive value can be relied upon (including 1), but a
value of 0 or no such metadata does not necessarily mean there are not
multiple subimages, it just means it could not be known from inexpensively
reading only the header. #2344 (2.1.4)
* The `imagesize_t` and `stride_t` values now have revised definitions.
It should be fully API/ABI compatible (at least for 64 bit systems), but
is a simpler, more modern, more platform-independent definition.
#2351 (2.1.5)
* `DeepData` has been altered to make pixel indices and total counts int64_t
rather than int, in order to be safe for very large images that have > 2
Gpixels. #2363 (2.1.5)
* On OSX, we now expect non-embedded plugins to follow the convention of
naming runtime-loaded modules `foo.imageio.so` (just like on Linux),
whereas we previously used the convention of `foo.imageio.dylib`. Turns
out that dylib is supposed to be only for shared libraries, not runtime
loadable modules. #2376 (2.1.6)
Fixes and feature enhancements:
* oiiotool:
- New `-evaloff` and `-evalon` lets you disable and enable the expression
substitution for regions of arguments (for example, if you have an
input image filename that contains `{}` brace characters that you want
interpreted literally, not evaluated as an expression). #2100 (2.1.0/2.0.4)
- `--dumpdata` has more intelligible output for uint8 images. #2124
(2.1.0/2.0.4)
- Fixed but that could prevent `-iconvert oiio:UnassociatedAlpha 1` from
correctly propagating to the input reader. #2172 (2.1.0/2.0.6)
- `-o:all=1` (which outputs all subimages to separate files) fixed a
crash that would occur if any of the subimages were 0x0 (it could
happen; now it just skips outputting those subimages). #2171 (2.1.0)
- Improved support of files with multiple subimages: Several commands
honored `-a` but did not respect individual `allsubimages=` modifiers
(--ch, --sattrib, --attrib, --caption, --clear-keywords,
--iscolorspace, --orientation, --clamp, -fixnan); Several commands
always worked on all subimages, but now properly respect `-a` and
`allsubimages=` (--origin, --fullpixels, --croptofull, --trim);
Several commands were totally unaware of subimages, but now are so and
respect `-a` and `allsubimages=` (--crop, --fullsize, --zover, --fill,
--resize, --resample). #2202 #2219, #2242 (2.1.1, 2.1.2)
- `--ociodisplay`: empty display or view names imply using the default
display or view. #2273 (2.0.10/2.1.3)
- `--metamerge` option causes binary image operations to try to "merge"
the metadata of their inputs, rather than simply copy the metadata
from the first input and ignore the others. #2311 (2.1.3)
- `--colormap` now supports a new "turbo" color map option. #2320 (2.1.4)
- Expression evaluation has been extended to support operators `//` for
integer division (whereas `/` is floating point division), and `%`
for integer modulus. #2362 (2.1.5)
- New `--originoffset` resets the data window origin relative to its
previous value (versus the existing `--origin` that sets it absolutely).
#2369 (2.1.5)
- `--paste` has two new optional modifiers: `:all=1` pastes the entire
stack of images together (versus the default of just pasting the top
two images on the stack), and `:mergeroi=1` causes the result to have
the merged data window of all inputs, instead of the foreground image
clipping against the boundary of the background image data. #2369 (2.1.5)
- `--paste` now works with deep images. #2369 (2.1.5)
- `--paste` semantics have changed: the meaning of pasting FG into BG at
(x,y) now means that the (0,0) origin of FG ends up at (x,y), whereas
before it placed the corner of FG's data window at (x,y). This will
not change behavior for ordinary images where FG's data window is (0,0),
but it makes behavior more sensible for "cropped" or "shrink-wrapped"
FG images that have non-zero data window origin. #2369 (2.1.5)
- `paste()` is now multithreaded and therefore much faster. #2369 (2.1.5)
- `--ociotransform` no longer issues an error message when no valid OCIO
configuration is found (because it's not needed for this operation).
#2371 (2.1.5)
- `--compare` would fail to notice differences in deep images where the
corresponding pixels had differing numbers of samples. #2381 (2.1.8)
* ImageBuf/ImageBufAlgo:
- `IBA::channel_append()` previously always forced its result to be float,
if it wasn't previously initialized. Now it uses the usual type-merging
logic, making the result the "widest" type of the inputs. #2095
(2.1.0/2.0.4)
- IBA `resize()`, `fit()`, and `resample()` are no longer restricted to
source and destination images having the same number of channels.
#2125 (2.1.0/2.0.5)
- Improve numerical precision of the unpremult/premult part of certain
color transformations. #2164 (2.1.0)
- `ImageBuf::read()` now properly forwards the "progress" parameters
to any underlying call to `read_image`. #2196 (2.1.1)
- The `OIIO_DISPATCH_COMMON_TYPES2/3` macros used internally by many IBA
functions have been expanded to handle a few more cases "natively"
without conversion to/from float. This may make a few cases of odd
data type combinations have higher precision. #2203 (2.0.8/2.1.1)
- IBA `resize()` fix precision issues for 'double' images. #2211
(2.0.8/2.1.1)
- `IBA::ociodisplay()`: empty display or view names imply using the
default display or view. #2273 (2.0.10/2.1.3)
- `IBA::fixNonFinite()`: fixed impicit float/double casts to half. #2301
(2.0.10/2.1.3)
- `IBA::color_map()`: now supports a new "turbo" color map option.
#2320 (2.1.4)
- `IBA::paste()` now works with deep images. #2369 (2.1.5)
- `paste` semantics have changed: the meaning of pasting FG into BG at
(x,y) now means that the (0,0) origin of FG ends up at (x,y), whereas
before it placed the corner of FG's data window at (x,y). This will
not change behavior for ordinary images where FG's data window is (0,0),
but it makes behavior more sensible for "cropped" or "shrink-wrapped"
FG images that have non-zero data window origin. #2369 (2.1.5)
- `paste()` is now multithreaded and therefore much faster. #2369 (2.1.5)
- `ociotransform()` no longer issues an error message when no valid OCIO
configuration is found (because it's not needed for this operation).
#2371 (2.1.5)
- Python `ociotransform` and `ociolook` mixed up the names and orders of
the `inverse` and `unpremult` params, making it so that you couldn't
properly specify the inverse. #2371 (2.1.5)
- `IBA::compare()` would fail to notice differences in deep images where
the corresponding pixels had differing numbers of samples. #2381 (2.1.8)
* ImageInput read_image/scanline/tile fixed subtle bugs for certain
combination of strides and channel subset reads. #2108 (2.1.0/2.0.4)
* ImageCache / TextureSystem / maketx:
- More specific error message when tile reads appear to be due to the
file having changed or been overwritten on disk since it was first
opened. #2115 (2.1.0/2.0.4)
- maketx: the `-u` (update mode) is slightly less conservative now,
no longer forcing a rebuild of the texture just because the file uses
a different relative directory path than last time. #2109 (2.1.0/2.0.4)
- Protection against certain divide-by-zero errors when using
very blurry latong environment map lookups. #2121 (2.1.0/2.0.5)
- `maketx -u` is smarter about which textures to avoid re-making because
they are repeats of earlier commands. #2140 (2.1.0/2.05)
- Fix possible maketx crash on Windows due to a stack overflow within
MSVS's implementation of std::regex_replace! #2173 (2.1.0/2.0.6)
- TS: New attribute "max_mip_res" limits filtered texture access to MIP
levels that are no higher than this resolution in any dimension. The
default is 1<<30, meaning no effective limit. #2174 (2.1.1)
- Stats now count the number of `TS::get_texture_info/IC::get_image_info`
calls, like it did before for texture, etc. #2223 (2.1.1)
- `TS::environment()` can resolve subimage by name, as we do for
texture() and texture3d(). #2263
- Improvements to error message propagation. (2.1.3)
- Avoid creating a new thread info struct while resolving udims. #2318
(2.1.4)
- Work around bug in OpenEXR, where dwaa/dwab compression can crash when
used on 1-channel tiled images with a tile size < 16. This can crop up
for MIP-maps (high levels where rez < 16), so we detect this case and
switch automatically to "zip" compression. #2378 (2.1.6)
- When converting images to texture (via maketx or IBA::make_texture),
correctly handle color space conversions for greyscale images.
#2400 (2.1.8)
* iv viewer:
- Image info window now sorts the metadata, in the same manner as
`iinfo -v` or `oiiotool -info -v`. #2159 (2.1.0/2.0.5)
* All command line utilities, when run with just `--help`, will exit with
return code 0. In other words, `utility --help` is not an error.
#2364 (2.1.5) #2383 (2.1.8)
* Python bindings:
- Fix inability for Python to set timecode attributes (specifically, it
was trouble setting ImageSpec attributes that were unsigned int
arrays). #2279 (2.0.9/2.1.3)
* Improved performance for ustring creation and lookup. #2315 (2.1.3)
* BMP:
- Fix bugs related to files with very high resolution (mostly 32 bit
int overflow issues and care to use 64 bit fseeks). Also speed up
reading and writing very large files. #2404 (2.1.8)
* DPX:
- Now recognizes the new transfer/colorimetric code for ADX. #2119
(2.1.0/2.0.4)
- Fix potential crash when file open fails. #2186 (2.0.7/2.1.1)
- Support for reading and writing 1-channel (luma, etc.) images. #2294
(2.0.10/2.1.3)
- Fix huge DPX reading performance regression. #2333 (2.1.4)
- Fix bugs related to int32 math that would lead to incorrect
behavior in very high-resolution files. #2396 (2.1.3)
* ffmpeg/Movie files:
- Reading individual frames from very-multi-image files (movie files) has
been greatly sped up (10x or more). #2345 (2.1.4)
- Support for reading movie files that (a) contain alpha channels, and
(b) have bit depths > 8 bits per channel. Previously, such files
would be read, but would be presented to the app as a 3-channel
8 bit/channel RGB. #2349 (2.1.5)
* FITS:
- Fix 16 and 32 bit int pixels which FITS spec says are signed, but we
were treating as unsigned. #2178 (2.1.0)
* HDR/RGBE:
- Fix bugs related to files with very high resolution (mostly 32 bit
int overflow issues and care to use 64 bit fseek). Also speed up
reading and writing very large files. #2406 (2.1.8)
* IFF
- Detect and error requests to open files for writing with resolutions
too high to be properly supported by IFF files. #2397 (2.1.8)
- Improve error messages when a file can't be opened. #2398 (2.1.8)
* JPEG:
- Read-from-memory is now supported via IOProxy use. #2180. (2.1.1)
* JPEG-2000:
- Disable JPEG-2000 support for the (rare) combination of an older
OpenJPEG 1.x and EMBEDPLUGINS=0 mode, which was buggy. The solution if
you really need EMBEDPLUGINS and JPEG-2000 support is to please use
OpenJPEG >= 2.0. #2183. (2.0.7/2.1.1)
* OpenEXR:
- Avoid some OpenEXR/libIlmImf internal errors with DWA compression by
switching to zip for single channel images with certain small tile
sizes. #2147 (2.1.0/2.0.5)
- Suppress empty string subimage name (fixes a problem with certain
V-Ray written multi-part exr images). #2190 (2.1.1/2.0.7)
- Fixed bug that broke th ability to specify compression of multipart
OpenEXR files. #2252 (2.1.2)
* PNG:
- More careful catching and reporting errors and corrupt PNG files.
#2167 (2.1.0/2.0.6)
- IOProxy reading is now supported. #2180. (2.1.1)
* PSD:
- When reading PSD files with multiple PhotoShop "layers", properly set
ImageSpec x, y to the image plane offset (upper left corner) of the
layer, and set and metadata "oiio:subimagename" to the layer name.
#2170 (2.1.0)
* RAW:
- Clarification about color spaces: The open-with-config hint
"raw:ColorSpace" is more careful about color primaries versus transfer
curve. Asking for "sRGB" (which is the default) gives you true sRGB --
both color primaries and transfer. Asking for "linear" gives you
linear transfer with sRGB/Rec709 primaries. The default is true sRGB,
because it will behave just like JPEG. #2260 (2.1.2)
- Added "raw:half_size" and "raw:user_mul" configuration attributes.
#2307 (2.1.3)
* RLA:
- Improved logic for determining the single best data type to report
for all channels. #2282 (2.1.3)
* SGI:
- Fix bugs when writing extremely high resolution images, due to
internal 32 bit arithmetic on file offsets. #2402 (2.1.8)
- Speed up reading and writing of SGI files. #2402 (2.1.8)
* Targa:
- Put in checks to detect and error requests to write Targa with
resolutions too high to be supported by the format. #2405 (2.1.8)
* TIFF:
- Fix problems with JPEG compression in some cases. #2117 (2.1.0/2.0.4)
- Fix error where reading just a subset of channels, if that subset did
not include the alpha channel but the image was "unassociated alpha",
the attempt to automatically associate (i.e. "premultiply" the alpha)
upon read would get bogus values because the alpha channel was not
actually read. Now in this case it will not do the premultiplication.
So if you are purposely reading RGB only from an RGBA file that is
specifically "unassociated alpha", beware that you will not get the
automatic premultiplication. #2122 (2.1.0/2.0.4)
- More careful check and error reporting when user tries to request
writing to a TIFF file mixed channel data types (which is not supported
by the underlying libtiff). #2112 (2.1.0/2.0.5)
- Fix crash reading certain old nconvert-written TIFF files.
#2207 (2.0.8/2.1.1)
- Fix bugs when reading TIFF "cmyk" files. #2292. (2.0.10/2.1.3)
- Correctly handle read and write of 6, 14, and 24 bit per sample
images. #2296 (2.1.3)
- Fix potential deadlock in TIFF I/O: minor flaw with threadpool method
#2327 (2.1.4)
* WebP:
- Fix bug that gave totally incorrect image read for webp images that
had a smaller width than height. #2120 (2.1.0/2.0.4)
* zfile:
- Put in checks to detect and error requests to write zfiles with
resolutions too high to be supported by the format. #2403 (2.1.8)
* Fix potential threadpool deadlock issue that could happen if you were
(among possibly other things?) simultaneously calling make_texture from
multiple application threads. #2132 (2.1.0/2.0.4)
* ImageInput/ImageOutput `create()` now properly lets you specify the type
for reader/writer from the format name itself (versus just the extension,
for example "openexr" versus "exr"). #2185 (2.1.1)
* Make all the various "could not open" messages across the writers use the
same phrasing. #2189 (2.1.1)
* Better care in some image readers/writers to avoid errors stemming from
integer overflow when compting the size of large images. #2232 (2.1.2)
Build/test system improvements and platform ports:
* Major overhaul of the CMake build system now that our CMake minimum is
3.12. #2348 #2352 #2357 #2360 #2368 #2370 #2372 #2373 (2.1.5) #2392 (2.1.8)
Highlights:
- All optional dependencies (e.g. "Pkg") now can be disabled (even if
found) with cmake -DUSE_PKG=0 or environment variable USE_PKG=0.
Previously, some packages supported this, others did not.
- All dependencies can be given find hints via -DPkg_ROOT=path or by
setting environment variable Pkg_ROOT=path. Previously, some did, some
didn't, and the ones that did had totally inconsistent names for the
path hint variable (PKG_HOME, PKG_ROOT_DIR, PKG_PATH, etc).
- Nice color coded status messages making it much more clear which
dependencies were found, which were not, which were disabled.
- Use standard BUILD_SHARED_LIBS to control shared vs static libraries,
replacing the old nonstandard BUILDSTATIC name.
- Use correct PUBLIC/PRIVATE marks with target_link_libraries and
target_include_directories, and rely on cmake properly understanding
the transitive dependencies.
- CMAKE_DEBUG_POSTFIX adds an optional suffix to debug libraries.
- CMAKE_CXX_STANDARD to control C++ standard (instead of our nonstandard
USE_CPP).
- CXX_VISIBILITY_PRESET controls symbol visibility defaults now, not
our nonstandard HIDE_SYMBOLS. And the default is to keep everything
hidden that is not part of the public API.
- At config time, `ENABLE_<name>=0` (either as a CMake variable or an
env variable) can be used to disable any individual file format or
command line utility. E.g., `cmake -DENABLE_PNG=0 -DENABLE_oiiotool=0`
This makes it easier to greatly reduce build time if you are 100%
sure there are formats or components you don't want or need.
- Config based install and usage.
* Deprecate "missingmath.h". What little of it is still needed (it mostly
addressed shortcomings of old MSVS releases) is now in fmath.h. #2086
* Remove "osdep.h" header that was no longer needed. #2097
* Appveyor scripts have been overhauled and simplified by relying on
`vcpkg` to build dependencies. #2113 (2.1.0/2.0.4)
* Detect and error if builder is trying to use a pybind11 that's too old.
#2144 (2.1.0/2.0.5)
* New CMake build-time option `OIIO_LIBNAME_SUFFIX` (default: empty) lets
you append an optional name to the libraries produced (to disambiguate
two builds at the same facility or distro, much like you could do before
for symbols with custom namespaces). #2148 (2.1.0)
* On MacOS 10.14 Mojave, fix warnings during `iv` compiler about OpenGL
being deprecated in future releases. #2151 (2.1.0/2.0.5)
* At build time, the Python version used can be controlled by setting the
environment variable `$OIIO_PYTHON_VERSION`, which if set will initialize
the default value of the CMake variable `PYTHON_VERSION`. #2161 (2.0.5/2.1.0)
* On non-Windows systems, the build now generates a PkgConfig file, installed
at `CMAKE_INSTALL_PREFIX/lib/pkgconfig/OpenImageIO.pc`. #2158 (2.0.5/2.1.0)
* A new unit test has been backported from master, which tries to perform a
series of read/write tests on every file format. In particular, this tests
certain error conditions, like files not existing, or the directory not
being writable, etc. #2181, #2189 (2.0.8/2.1.1)
* Support for CI tests on CircleCI. #2194 (2.1.1) Retired in #2389 (2.1.8).
* New build-time flag `USE_WEBP=0` can be used to disable building WebP
format support even on platforms where webp libraries are found.
#2200 (2.1.1)
* Fix compiler warnings on Windows. #2209 #2213 #2214 #2392
* Crashes in the command line utilities now attempt to print a stack trace
to aid in debugging (but only if OIIO is built with Boost >= 1.65, because
it relies on the Boost stacktrace library). #2229 (2.0.8/2.1.1)
* Add gcc9 to Travis tet matrix and fix gcc9 related warnings. #2235 (2.1.2)
* VDB reader pulled in the TBB libraries using the wrong CMake variable.
#2274 (2.1.3)
* The embedded `fmt` implementation has been updated to fix windows
warnings. #2280 (2.1.3)
* Improvements for finding certain new Boost versions. #2293 (2.0.10/2.1.3)
* Build fixes for MinGW. #2304, #2308 (2.0.10/2.1.3)
* libraw: Fixes to make it build properly against some changes in the
libraw development master. #2306 (2.1.3)
* Use GitHub Actions CI. Eliminate Appveyor and some Travis tests.
#2334 (2.1.4) #2356 (2.1.5) #2395 (2.1.8)
* Updated and improved finding of OpenEXR and `build_openexr.bash` script
that we use for CI. #2343 (2.1.4)
* Upgrade the pybind11 version that we auto-install when not found (to 2.4.2),
and add logic to detect the presence of some pybind11 versions that are
known to be (buggily) incompatible with C++11. #2347 (2.1.5)
* Fix errors in very new MSVS versions where it identified a suspicious
practice of ImageBuf's use of a unique_ptr of an undefined type. Jump
through some hoops to make that legal. #2350 (2.1.5)
* All Python scripts in the tests have been modified as needed to make them
correct for both Python 2.7 and 3.x. #2355, #2358 (2.1.5)
* Tests are now safe to run in parallel and in unspecified order. Running
with env variable CTEST_PARALLEL_LEVEL=[something more than 1] greatly
speeds up the full testsuite on multi-core machines. #2365 (2.1.5)
* Bump robin map version to latest release (v0.6.2) #2401 (2.1.8)
* Fix compiler warnings in ustring.h when `_LIBCPP_VERSION` is not defined.
#2415 (2.1.8.1)
* Bump fmt library to v6.1.0. #2423 (2.1.8.1)
Developer goodies / internals:
* argparse.h:
- Add unit tests. #2192 (2.1.1)
- Add "%1" which is like "%*" but its list receives only arguments that
come *before* any other dash-led arguments. #2192 (2.1.1)
- Allow specifiers such as "%d:WIDTH" the part before the colon is the
type specifier, the part after the colon is the name of the parameter
for documentation purposes. #2312 (2.1.3)
* attrdelegate.h:
- New header implements "attribute delegates." (Read header for details)
#2204 (2.1.1)
* dassert.h:
- Spruce up assertion macros: more uniform wording, and use pretty
function printing to show what function the failure was in. #2262
- The new preferred assertion macros are `OIIO_ASSERT` and `OIIO_DASSERT`.
The `OIIO_ASSERT` always tests and prints an error message if the test
fails, but now only aborts when compiled without NDEBUG defined (i.e.
no abort for release builds), whereas `OIIO_DASSERT` is for debug mode
only and does nothing at all (not even perform the test) in release
mode. These names and behaviors are preferred over the old `ASSERT`
and `DASSERT`, though those deprecated names will continue for at least
another major release. #2411 (2.1.8.1)
* filesystem.h:
- Change many filesystem calls to take string_view arguments. #2388 (2.1.8)
- New `fseek()` and `ftell()` that always use 64 bit offsets to be safe
for very large files. #2399 (2.1.8)
* fmath.h:
- `safe_mod()` does integer modulus but protects against mod-by-zero
exceptions. #2121 (2.1.0/2.0.5)
- pow2roundup/pow2rounddown have been renamed ceil2/floor2 to reflect
future C++20 standard. The old names still work, so it's a fully back
compatible change. #2199 (2.0.8/2.1.1)
- To match C++20 notation, use `rotl()` template innstead of separate
rotl32/rotl64 functions. #2299, #2309 (2.1.3)
* platform.h:
- New `OIIO_RETURNS_NONNULL` macro implements an attribute that marks
a function that returns a pointer as guaranteeing that it's never
NULL. #2150 (2.1.0/2.0.5)
* SHA1.h:
- Upgraded this embedded code from version 1.8 (2008) to the newest
release, 2.1 (2012). This fixes some Windows warnings. #2342 (2.1.4)
* simd.h:
- Added vec4 * matrix44 multiplication. #2165 (2.1.0/2.0.6)
- Guard against shenanigans when Xlib.h having been included and
`#define`ing True and False. #2272 (2.0.9/2.1.3)
* strutil.h:
- Added `excise_string_after_head()`. #2173 (2.1.0/2.0.6)
- Fixed incorrect return type of `stof()`. #2254 (2.1.2)
- Added `remove_trailing_whitespace()` and `trim_whitespace()`. #2298
(2.1.3)
- `Strutil::wordwrap()` now lets you specify the separation characters
more flexibly (rather than being hard-coded to spaces as separators).
#2116 (2.1.0/2.0.4)
- `Strutil::parse_while()`. #2139 (2.1.0/2.0.5)
- Added a variety of `join()` that allows you to set the number of items
joined, truncating or padding with default values as needed. #2408
(2.1.8)
- Fix `join` to produce a joined string of float-like values with
locale-independent formatting. #2408 (2.1.8)
- Fix `vsnprintf` to be locale independent. #2410 (2.1.8)
- New `lstrip()` and `rstrip()` are just like the existing `strip()`,
but operate only on the beginning/left side or ending/right side of
the string, respectively. #2409 (2.1.8)
* string_view.h:
- `string_view` now adds an optional `pos` parameter to the `find_first_of`
/ `find_last_of` family of methods. #2114 (2.1.0/2.0.4)
* sysutil.h:
- Added `stacktrace()` and `setup_crash_stacktrace()`. (Only functional
if OIIO is built with Boost >= 1.65, because it relies on the Boost
stacktrace library). #2229 (2.0.8/2.1.1)
* unittest.h:
- Add `OIIO_CHECK_IMAGEBUF_STATUS()` test macro. #2394 (2.1.8)
* unordered_map_concurrent.h:
- Performance improvement by avoiding redundant hashing of keys, and
improving the speed and properties of the hash function. #2313, #2316
(2.1.3)
* ustring.h:
- Bug fix in `ustring::compare(string_view)`, in cases where the
string_view was longer than the ustring, but had the same character
sequence up to the length of the ustring. #2283 (2.0.10/2.1.3)
* Wide use of declaring methods `noexcept` when we want to promise that
they won't throw exceptions. #2156, #2243 (2.1.0, 2.1.2)
* Changed all (we think) internal string formatting that expects printf
formatting notation to use the errorf/sprintf style calls, in anticipation
of the error/format (no trailing -f) calls to eventually follow the
std::format/python formatting notation. #2393 (2.1.8)
Notable documentation changes:
* The whole documentation system has been overhauled. The main docs have
been converted from LaTeX to Sphinx (using Doxygen and Breathe) for
beautiful HTML as well as PDF docs and automatic hosting on
https://openimageio.readthedocs.io #2247,2250,2253,2255,2268,2265,2270
* Copyright notices have been changed for clarity and conformance with
SPDX conventions. #2264
* New GitHub issue templates, making separate issue types for bug reports,
feature requests, build problems, and questions. #2271,#2346
Release 2.0.13 (1 Dec 2019) -- compared to 2.0.12
--------------------------------------------------
* Bug fix in deep image compare (`IBA::compare()` or `oiiotool --compare`)
would fail to notice differences in deep images where the corresponding
pixels had differing numbers of samples. #2381 (2.1.8/2.0.13)
* DPX: Fix bugs related to int32 math that would lead to incorrect behavior
in very high-resolution files. #2396 (2.1.3/2.0.13)
* When converting images to texture (via maketx or IBA::make_texture),
correctly handle color space conversions for greyscale images. #2400
(2.1.8/2.0.13)
* Build: suppress warnings with libraw for certain gcc versions.
* Build: Fix compiler warnings in ustring.h when `_LIBCPP_VERSION` is not
defined. #2415 (2.1.8.1/2.0.13)
* filesystem.h: New `fseek()` and `ftell()` that always use 64 bit offsets
to be safe for very large files. #2399 (2.1.8/2.0.13)
* `Strutil::parse_string()` - fix bugs that would fail for escaped quotes
within the string. #2386 (2.1.8/2.0.13)
* `Strutil::join()` added a variety that allows you to set the number of
items joined, truncating or padding with default values as needed. #2408
(2.1.8/2.0.13)
* New `Strutil::lstrip()` and `rstrip()` are just like the existing `strip()`,
but operate only on the beginning/left side or ending/right side of
the string, respectively. #2409 (2.1.8/2.0.13)
Release 2.0.12 (1 Nov, 2019) -- compared to 2.0.11
--------------------------------------------------
* Fix compiler warnings on some platform. #2375
* Work around bug in OpenEXR, where dwaa/dwab compression can crash when
used on 1-channel tiled images with a tile size < 16. This can crop up for
MIP-maps (high levels where rez < 16), so we detect this case and switch
automatically to "zip" compression. #2378
Release 2.0.11 (1 Oct, 2019) -- compared to 2.0.10
-------------------------------------------------
* Fixes to build against LibRaw master. #2306
* Fix DPX reading performance regression. #2333
* Guard against buggy pybind11 versions. #2347
* Fixes for safe Cuda compilation of `invert<>` in fmath.h. #2197
Release 2.0.10 (1 Aug, 2019) -- compared to 2.0.9
-------------------------------------------------
* ColorConfig improvements: (a) new getColorSpaceFamilyByName(); (b) new
methods to return the list of all color spaces, looks, displays, or views
for a display; (c) all of ColorConfig now exposed to Python. #2248
* `IBA::ociodisplay()` and `oiiotool --ociodisplay`: empty display or view
names imply using the default display or view. #2273
* Bug fix in `ustring::compare(string_view)`, in cases where the string_view
was longer than the ustring, but had the same character sequence up to
the length of the ustring. #2283
* `oiiotool --stats`: Fixed bug where `-iconfig` hints were not being
applied to the file as it was opened to compute the stats. #2288
* Bug fix: `IBA::computePixelStats()` was not properly controlling the
number of threads with the `nthreads` parameter. #2289
* Bug fix when reading TIFF bugs: In cases where the reader needed to close
and re-open the file silently (it could happen for certain scanline
traversal patterns), the re-open was not properly honorig any previous
"rawcolor" hints from the original open. #2285
* Nuke txWriter updates that expose additional make_texture controls. #2290
* Build system: Improvements for finding certain new Boost versions. #2293
* Build system: Improvements finding OpenEXR installation.
* Fix bugs when reading TIFF "cmyk" files. #2292.
* DPX: support for reading and writing 1-channel (luma, etc.) DPX images.
#2294
* `IBA::fixNonFinite()`: fixed impicit float/double casts to half. #2301
* Build fixes for MinGW. #2304
Release 2.0.9 (4 Jul, 2019) -- compared to 2.0.8
------------------------------------------------
* RAW: Clarification about color spaces: The open-with-config hint
"raw:ColorSpace" is more careful about color primaries versus transfer
curve. Asking for "sRGB" (which is the default) gives you true sRGB --
both color primaries and transfer. Asking for "linear" gives you linear
transfer with sRGB/Rec709 primaries. The default is true sRGB, because it
will behave just like JPEG. #2260 (2.1.2)
* Improved oiiotool support of files with multiple subimages: Several
commands honored `-a` but did not respect individual `allsubimages=`
modifiers (--ch, --sattrib, --attrib, --caption, --clear-keywords,
--iscolorspace, --orientation, --clamp, -fixnan); Several commands always
worked on all subimages, but now properly respect `-a` and `allsubimages=`
(--origin, --fullpixels, --croptofull, --trim); Several commands were
totally unaware of subimages, but now are so and respect `-a` and
`allsubimages=` (--crop, --fullsize, --zover, --fill, --resize,
--resample). #2202 #2219, #2242
* Fix broken ability to specify compression of multipart exr files. #2252
* Fix Strutil::stof() return type error and other windows warnings. #2254
* IBA::colortmatrixtransform() and `oiiotool --ccmatrix` allow you to
perform a matrix-based color space transformation. #2168
* Guard simd.h against shenanigans when Xlib.h having been included and
`#define`ing True and False. #2272
* RAW: Clarification about color spaces: The open-with-config hint
"raw:ColorSpace" is more careful about color primaries versus transfer
curve. Asking for "sRGB" (which is the default) gives you true sRGB --
both color primaries and transfer. Asking for "linear" gives you linear
transfer with sRGB/Rec709 primaries. The default is true sRGB, because it
will behave just like JPEG. #2260
* Fix inability for python to set timecode attributes (specifically, it was
trouble setting ImageSpec attributes that were unnsigned int arrays).
#2279
Release 2.0.8 (3 May, 2019) -- compared to 2.0.7
------------------------------------------------
* Fix Windows broken read of JPEG & PNG in some circumstances. #2231
* Some minor fixes to JPEG & PNG reading and file error robustness. #2187
* Fix crash reading certain old nconvert-written TIFF files. #2207
* Internals: The `OIIO_DISPATCH_COMMON_TYPES2/3` macros used by many
ImageBufAlgo functions have been expanded to handle a few more cases
"natively" without conversion to/from float. This may make a few cases
of odd data type combinations have higher precision. #2203
* ImageBufAlgo::resize() fixes precision issues for 'double' images. #2211
* Testing: A new unit test has been backported from master, which tries to
perform a series of read/write tests on every file format. In partcular,
this tests certain error conditions, like files not existing, or the
directory not being writable, etc. #2181
* Crashes in the command line utilities now attempt to print a stack trace
to aid in debugging (but only if OIIO is built with Boost >= 1.65, because
it relies on the Boost stacktrace library). #2229
* Dev goodies: fmath.h's powwroundup/pow2rounddown have been renamed
ceil2/floor2 to reflect future C++ standard. The old names still work, so
it's a fully back compatible change. #2199
Release 2.0.7 (1 Apr, 2019) -- compared to 2.0.6
------------------------------------------------
* DPX: fix potential crash when file open fails. #2186
* EXR: Suppress empty string for subimage name (fixes a problem when reading
files written by V-Ray). #2190
* Disable JPEG-2000 support for the (rare) combination of an older OpenJPEG
1.x and EMBEDPLUGINS=0 mode, which was buggy. The solution if you really
need EMBEDPLUGINS and JPEG-2000 support is to please use OpenJPEG >= 2.0.
#2183.
* New build flag `USE_WEBP=0` can be set to 0 to force disabled support of
WebP even when the webp package is found. #2200
* Bug fix: `ImageInput::create(name)` and `ImageOutput::create(name)` worked
if `name` was a filename (such as `foo.exr`), or the extension (such as
`exr`), but previously did not work if it was the name of the format
(such as `openexr`), despite having been documented as working in that
case. #2185
Release 2.0.6 (1 Mar, 2019) -- compared to 2.0.5
------------------------------------------------
* PNG: more careful catching of errors and corrupt png files. #2167
* PSD: read now properly extracts layer/subimage name and data window offset
coordinates. #2170
* ImageBuf: Fix bug in propagating unassociated alpha behavior request. #2172
* `oiiotool -o:all=1` fix crash when outputting 0x0 subimages. #2171
* Developer goodies: simd.h ops for vec4 * mat44 multiplication. #2165
* Developer goodies: `Strutil::excise_string_after_head()` #2173
* Fix crashes on Windows from certain regex replacement happening as part
of MakeTexture (internally avoid MSVS implementation of std::regex). #2173
Release 2.0.5 (1 Feb, 2019) -- compared to 2.0.4
------------------------------------------------
* `resize()`, `fit()`, and `resample()` are no longer restricted to
source and destination images having the same numer of channels. #2125
* Python error reporting for `ImageOutput` and `ImageBuf.set_pixels` involving
transferring pixel arrays have changed from throwing exceptions to reporting
errors through the usual OIIO error return codes and queries. #2127
* Protection against certain divide-by-zero errors when using very blurry
latlong environment map lookups. #2121
* New shell environment variable `OPENIMAGEIO_OPTIONS` can now be used to
set global `OIIO::attribute()` settings upon startup (comma separated
name=value syntax). #2128
* ImageInput open-with-config new attribute `"missingcolor"` can supply
a value for missing tiles or scanlines in a file in lieu of treating it
as an error (for example, how OpenEXR allows missing tiles, or when reading
an incompletely-written image file). A new global `OIIO::attribute()`
setting (same name) also accomplishes the same thing for all files read.
Note that this is only advisory, and not all file times are able to do
this (OpenEXR is the main one of interest, so that works). #2129
* New filter name `"nuke-lanczos6"` matches the "lanczos6" filter from Nuke.
In reality, it's identical to our "lanczos3", but the name alias is
supposed to make it more clear which one to use to match Nuke, which uses
a different nomenclature (our "3" is radius, their "6" is full width).
#2136
* `maketx -u` is smarter about which textures to avoid re-making because
they are repeats of earlier commands. #2140
* Detect/error if builder is trying to use a pybind11 that's too old. #2144
* OpenEXR: avoid some OpenEXR/libIlmImf internal errors with DWA compression
by switching to zip for single channel images with certain small tile
sizes. #2147
* On MacOS 10.14 Mojave, fix warnings during `iv` compile about OpenGL
being deprecated in future releases. #2151
* `iv` info window now sorts the metadata. #2159
* At build time, the Python version used can be controlled by setting the
environment variable `$OIIO_PYTHON_VERSION`, which if set will initialize
the default value of the CMake variable `PYTHON_VERSION`. #2161 (2.0.5)
* On non-Windows systems, the build now generates a PkgConfig file, installed
at `CMAKE_INSTALL_PREFIX/lib/pkgconfig/OpenImageIO.pc`. #2158 (2.0.5)
Release 2.0.4 (Jan 5, 2019) -- compared to 2.0.3
------------------------------------------------
* Fix potential threadpool deadlock issue that could happen if you were
(among possibly other things?) simultaneously calling make_texture from
multiple application threads. #2132
* ImageInput read_image/scanline/tile fixed subtle bugs for certain
combination of strides and channel subset reads. #2108
* TIFF: Fix problems with JPEG compression in some cases. #2117
* TIFF: Fixed error where reading just a subset of channels, if that subset
did not include the alpha channel but the image was "unassociated alpha",
the attempt to automatically associate (i.e. "premultiply" the alpha) upon
read would get bogus values because the alpha channel was not actually
read. Now in this case it will not do the premultiplication. So if you are
purposely reading RGB only from an RGBA file that is specifically
"unassociated alpha", beware that you will not get the automatic
premultiplication. #2122
* Python: define `__version__` for the module. #2096
* IBA::channel_append() previously always forced its result to be float, if
it wasn't previously initialized. Now it uses the uaual type-merging
logic, making the result the "widest" type of the inputs. #2095
* ImageSpec::find_attribute now will retrive "datawindow" and "displaywindow"
(type int[4] for images int[6] for volumes) giving the OpenEXR-like bounds
even though there is no such named metadata for OIIO (the results will
assembled from x, y, width, height, etc.). #2110
* ImageCache/TextureSystem: more specific error message when tile reads
appear to be due to the file having changed or been overwritten on disk
since it was first opened. #2115
* oiiotool: New `-evaloff` and `-evalon` lets you disable and enable
the expression substitution for regions of arguments (for example, if
you have an input image filename that contains `{}` brace characters that
you want interpreted literally, not evaluated as an expression). #2100
* oiiotool `--dumpdata` has more intelligible output for uint8 images. #2124
* maketx: the `-u` (update mode) is slightly less conservative now,
no longer forcing a rebuild of the texture just because the file uses
a different relative directory path than last time. #2109
* WebP: fix bug that gave totally incorrect image read for webp images that
had a smaller width than height. #2120
* Developer goodies: string_view now adds an optional `pos` parameter to the
`find_first_of`/`find_last_of` family of methods. #2114
* Dev goodies: Strutil::wordwrap() now lets you specify the separation
characters more flexibly (rather than being hard-coded to spaces as
separators). #2116
Release 2.0 (Dec 1, 2018) -- compared to 1.8.x
----------------------------------------------
New minimum dependencies:
* On Windows compiling with MSVS, the new minimum version is MSVS 2015.
Major new features and improvements:
* ImageInput and ImageOutput static create() and open() methods now return
`unique_ptr` rather than raw pointers. #1934, #1945 (1.9.3).
* ImageInput improvements to thread safety and concurrency, including some
new API calls (see "Public API changes" section below).
* ImageBufAlgo overhaul (both C++ and Python): Add IBA functions that
return image results directly rather than passing ImageBuf references
as parameters for output (the old kind of calls still exist, too, and
have their uses). Also in C++, change all IBA functions that took raw
pointers to per-channel colors into `span<>` for safety. #1961 (1.9.4)
* For some readers and writers, an "IOProxy" can be passed that customizes
the I/O methods. An important use of this is to write an image "file"
to memory or to read an image "file" from a memory, rather than disk.
Currently, OpenEXR supports this for both reading and writing, and PNG
supports it for writing. You specify a pointer to the proxy via the
configuration option "oiio:ioproxy". #1931 (1.9.3)
* New Image Format support:
* OpenVDB file read (as volume images or accessing via texture3d()).
#2010,2018 (1.9.4)
* "null" images -- null reader just returns black (or constant colored)
pixels, null writer just returns. This can be used for benchmarking
(to eliminate all actual file I/O time), "dry run" where you want to
test without creating output files. #1778 (1.9.0), #2042 (1.9.4)
* TIFF I/O of multiple scanlines or tiles at once (or whole images, as is
typical use case for oiiotool and maketx) is sped up by a large factor
on modern multicore systems. We've seen 10x or more faster oiiotool
performance for uint8 and uint16 TIFF files using "zip" (deflate)
compression, on modern 12-16 core machines. #1853 (1.9.2)
* Major refactor of Exif metadata handling, including much more complete
metadata support for RAW formats and support of camera "maker notes"
for Canon cameras. #1774 (1.9.0)
* New `maketx` option `--bumpslopes` specifically for converting bump maps,
saves additional channels containing slope distribution moments that can
be used in shaders for "bump to roughness" calculations. #1810,#1913,2005
(1.9.2), #2044 (1.9.4)
* An official FindOpenImageIO.cmake that we invite you to use in other
cmake-based projects that needs to find OIIO. #2027 (1.9.4)
Public API changes:
* **Python binding overhaul**
The Python bindings have been reimplemented with
[`pybind11`](https://github.com/pybind/pybind11), no longer with Boost.Python.
#1801 (1.9.1)
In the process (partly due to what's easy or hard in pybind11, but partly
just because it caused us to revisit the python APIs), there are some minor
API changes, some of which are breaking! To wit:
* All of the functions that are passed or return blocks of pixels
(such as `ImageInput.read_image()`) now use Numpy `ndarray` objects
indexed as `[y][x][channel]` (no longer using old-style Python
`array.array` and flattened to 1D).
* Specilized enum type `ImageInput.OpenMode` has been replaced by string
parameters, so for example, old `ImageInput.open(filename, ImageInput.Create)`
is now `ImageInput.open (filename, "Create")`
* Any function that previously took a parameter of type `TypeDesc`
or `TypeDesc.BASETYPE` now will accept a string that signifies the
type. For example, `ImageBuf.set_write_format("float")` is now a
synonym for `ImageBuf.set_write_format(oiio.TypeDesc(oiio.FLOAT))`.
* For several color conversion functions, parameter names were changed
from "from" to "fromspace" and "to" to "tospace" to avoid a clash with
the Python reserved word `from`. #2084
* **ImageInput API changes for thread safety and statelessness** #1927 (1.9.2)
* `seek_subimage()` no longer takes an `ImageSpec&`, to avoid the obligatory
copy. (If the copy is desired, just call `spec()` to get it afterwards.)
* All of the `read_*()` methods now have varieties that take arguments
specifying the subimage and mip level. The `read_native_*()` methods
supplied by ImageInput subclass implementations now ONLY come in the
variety that takes a subimage and miplevel.
* All of the `read_*()` calls that take subimage/miplevel explicitly are
guaranteed to be stateless and thread-safe against each other (it's not
necessary to call `seek_subimage` first, nor to have to lock a mutex to
ensure that another thread doesn't change the subimage before you get a
chance to call read). For back-compatibility, there are still versions
that don't take subimage/miplevel, require a prior call to seek_subimge,
and are thus not considered thread-safe.
* New methods `spec(subimage,miplevel)` and `spec_dimensions(s,m)`
let you retrieve a copy of the ImageSpec for a given subimage and
MIP level (thread-safe, and without needing a prior `seek_subimage`)
call. Note that to be stateless and thread-safe, these return a COPY
of the spec, rather than the reference returned by the stateful
`spec()` call that has no arguments and requires a prior `seek_subimage`.
However, `spec_dimensions()` does not copy the channel names or the
arbitrary metadata, and is thus very inexpensive if the only thing
you need from the spec copy is the image dimensions and channel
formats.
* **ImageInput and ImageOutput create/open changes**
* The static `create()` and `open()` methods have been changed so that
instead of returning an `ImageInput *` (or `ImageOutput *`) and
requiring the caller to correctly manage that resource and eventually
destroy it, now they return a `unique_ptr` that automatically deletes
when it leaves scope. In the process we also clean up some edge cases
on Windows where it was possible for ImageInput/ImageOutput to have
been allocated in one DLL's heap but freed in a different DLL's heap,
which could cause subtle heap corruption problems. #1934,#1945 (1.9.3).
* **ImageBuf**
* New method `set_origin()` changes the pixel data window origin.
#1949 (1.9.4)
* Assignment (`operator=`) is now enabled for ImageBuf, both the copying
and moving variety. Also, an explicit copy() method has been added
that returns a full copy of the ImageBuf. #1952 (1.9.4)
* write() method has had its arguments changed and now takes an optional
TypeDesc that lets you specify a requested data type when writing the
output file, rather than requiring a previous and separate call to
set_write_format(). The old call signature of write() still exists,
but it will be considered deprecated in the future. #1953 (1.9.4)
* **ImageBufAlgo**
* In C++, functions that take raw pointers for per-channel constant
values or results are deprecated, in favor of new versions that
heavily rely on `span<>` to safely pass array references and their
lengths. #1961 (1.9.4)
* In both C++ and Python, every IBA function that takes a parameter
giving an ImageBuf destination reference for results have an additional
variant that directly returns an ImageBuf result. This makes much
cleaner, more readable code, in cases where it's not necessary to
write partial results into an existing IB. #1961 (1.9.4)
* In C++, many IBA functions that came in multiple versions for whether
certain parameters could be an image, a per-channel constant, or a
single constant, have been replaced by a single version that takes
a new parameter-passing helper class, `Image_or_Const` that will match
against any of those choices. (No changes are necessary for calling
programs, but it makes the header and documentation a lot simpler.)
#1961 (1.9.4)
* IBA compare(), computePixelStats(), and histogram() now directly
return their result structures, intead of requiring the passing of
a destination reference. #1961 (1.9.4)
* New IBA::fit() resizes and image to just fit in the given size, but
preserve its aspect ratio (padding with black as necessary). It's just
like what `oiiotool --fit` has always done, but now you can call it
directly from C++ or Python. #1993 (1.9.4)
* New `contrast_remap()` allows flexible linear or sigmoidal contrast
remapping. #2043 (1.9.4)
* `ImageBufAlgo::colorconvert` and various `ocio` transformations have
changed the default value of their `unpremult` parameter from `false`
to `true`, reflecting the fact that we believe this is almost always
the more correct choice. Also, if their input image is clearly marked
as having unasociated alpha already, they will not bracket the color
conversion with the requested unpremult/premult. #1864 (1.9.2)
* Updated the OpenCV interoperability with new functions to_OpenCV (make
an ImageBuf out of a cv::Mat) and from_OpenCV (fill in a cv::Mat with
the contents of an ImageBuf). Deprecated the old from_IplImage and
to_IplImage, which are very OpenCV-1.x-centric. (2.0.2)
* **ImageCache/TextureSystem:**
* ImageCache and TextureSystem now have `close(filename)` and
`close_all()` methods, which for one file or all files will close the
files and release any open file handles (also unlocking write access
to those files on Windows), but without invalidating anything it knows
about the ImageSpec or any pixel tiles already read from the files, as
would happen with a call to the much more drastic `invalidate()` or
`invalidate_all()`. #1950 (1.9.4)
* `TextureSystem::create()` has an additional optional argument that
allows the caller to pass an existing app-owned custom ImageCache.
#2019 (1.9.4)
* New `TextureSystem::imagecache()` method returns a blind, non-owning
pointer to the underlying ImageCache of that TS. #2019 (1.9.4)
* ImageCache: extended add_tile() with an optional `copy` parameter
(which defaults to `true`), which when set to `false` will make a tile
that references an app buffer without allocating, copying, and owning
the memory. In short, this makes it possible to reference existing
memory holding an image array, as if it were a texture. #2012 (1.9.4)
* `ImageCache::add_file()` extended with an optional `replace` parameter
(default: false), that if true, will replace the tile and invalidate
the old one. #2021 (1.9.4)
* **Changes to string formatting**: #2076 (2.0.1)
* New `Strutil::sprintf()` and `ustring::sprintf()` functions are for
printf-style formatted errors and warnings. You are encouraged to
change your existing `format()` calls to `sprintf()`, since the
original `format` may in a later version (2.1?) switch to Python-style
formatting commands, but `sprintf` will continue to reliably use
C printf style notation.
* In ImageInput, ImageOutput, ImageBuf, and ErrorHandler, new `errorf()`
and `warningf()` methods similarly provide printf-style formatted
errors and warnings. The old `error()/warning()` calls will someday
(maybe 2.1?) switch to Python-style formatting commands, but
`errorf` will continue to reliably use C printf style notation.
* ColorConfig changes: ColorConfig methods now return shared pointers to
`ColorProcessor` rather than raw pointers. It is therefore no longer
required to make an explicit delete call. Created ColorProcessor objects
are now internally cached, so asking for the same color transformation
multiple times is no longer expensive. The ColorProcessor interface is
now in `color.h` and can be directly used to perform transformations on
individual colors (previously it was just an opaque pointer and could
only be used to pass into certain IBA functions). The color space names
"rgb" and "default" are now understood to be synonyms for the default
"linear" color space. #1788 (1.9.0)
* Remove long-deprecated API calls:
* ImageBuf::get_pixels/get_pixel_channels varieties deprecated since 1.6.
* ImageBuf::set_deep_value_uint, deprecated since 1.7.
* ImageBuf::deep_alloc, deprecated since 1.7.
* ImageBufAlgo::colorconvert variety deprecated since 1.7.
* ImageCache::clear, deprecated since 1.7.
* ImageCache::add_tile variety deprecated since 1.6.
* ROI new methods: contains() #1874, #1878 (1.9.2)
* `ImageBufAlgo::pixeladdr()` now takes an additional optional parameter,
the channel number. #1880 (1.9.2)
* Global OIIO attribute "log_times" (which defaults to 0 but can be overridden
by setting the `OPENIMAGEIO_LOG_TIMES` environment variable), when nonzero,
instruments ImageBufAlgo functions to record the number of times they are
called and how much time they take to execute. A report of these times
can be retrieved as a string as the "timing_report" attribute, or it will
be printed to stdout automatically if the value of log_times is 2 or more
at the time that the application exits. #1885 (1.9.2)
* Moved the definition of `ROI` from `imagebuf.h` to `imageio.h` and make
most of the methods `constexpr`. #1906 (1.9.2)
* Rename/move of `array_view` to `span`. Deprecated `array_view` and moved
array_view.h contents to span.h. You should change `array_view<T>`
to `span<T>` and `array_view<const T>` to `cspan<T>`. #1956,2062 (1.9.4)
* ustring: removed `operator int()` that allowed simple int casting such as:
```
ustring u, v;
if (u || !v) { ... }
```
This was error-prone, neither std::string nor std::string_view had the
equivalent, so we are removing it. The preferred idiom is:
```
if (!u.empty() || v.empty()) { ... }
```
Performance improvements:
* ImageBufAlgo::computePixelStats is now multithreaded and should improve by
a large factor when running on a machine with many cores. This is
particularly noticable for maketx. #1852 (1.9.2)
* Color conversions are sped up by 50% for 4 channel float images, about
30% for other combinations of channels or data formats. #1868 (1.9.2)
* ImageBuf::get_pixels() sped up by around 3x for the common case of the
image being fully in memory (the slower path is now only used for
ImageCache-based images). #1872 (1.9.2)
* ImageBufAlgo::copy() and crop() sped up for in-memory buffers, by about
35-45% when copying between buffers of the same type, 2-4x when copying
between buffers of different data types. #1877 (1.9.2)
* ImageBufAlgo::over() when both buffers are in-memory, float, 4-channels,
sped up by about 2x. #1879 (1.9.2).
* ImageBufAlgo::fill() of a constant color sped up by 1.5-2.5x (depending
on the data type involved). #1886 (1.9.2)
Fixes and feature enhancements:
* oiiotool
* `--help` prints important usage tips that explain command parsing,
syntax of optional modifiers, and the path to PDF docs. #1811 (1.9.2)
* `--colormap` has new maps "inferno", "magma", "plasma", "viridis",
which are perceptually uniform, monotonically increasing luminance,
look good converted to greyscale, and usable by people with color
blindness. #1820 (1.9.2)
* oiiotool no longer enables autotile by default. #1856 (1.9.2)
* `--colorconvert`, `--tocolorspace`, and all of the `--ocio` commands
now take an optional modifier `:unpremult=1` which causes the color
conversion to be internally bracketed by unpremult/premult steps (if
the image has alpha and is not already marked as having unassociated
alpha). You should therefore prefer `--colorconvert:unpremult=1 from to`
rather than the more complex `--unpremult --colorconvert from to -premult`.
#1864 (1.9.2)
* `--autocc` will also cause unpremult/premult to bracket any color
transformations it does automatically for read and write (if the image
has alpha and does not appear to already be unassociated). #1864 (1.9.2)
* `--help` prints the name of the OCIO color config file. #1869 (1.9.2)
* Frame sequence wildcard improvements: fix handling of negative frame
numbers and ranges, also the `--frames` command line option is not
enough to trigger a loop over those frame numbers, even if no other
arguments appear to have wildcard structure. #1894 (1.8.10/1.9.2)
* `--info -v` now prints metadata in sorted order, making it easier to
spot the existance of particular metadata. #1982 (1.9.4)
* `--no-autopremult` fixed, it wasn't working properly for cases that
were read directly rather than backed by ImageCache. #1984 (1.9.4)
* New `--contrast` allows for contrast remapping (linear or sigmoidal).
#2043 (1.9.4)
* Improved logic for propagating the pixel data format through
multiple operations, especially for files with multiple subimages.
#1769 (1.9.0/1.8.6)
* Outputs are now written to temporary files, then atomically moved
to the specified filename at the end. This makes it safe for oiiotool
to "overwrite" a file (i.e. `oiiotool in.tif ... -o out.tif`) without
problematic situations where the file is truncated or overwritten
before the reading is complete. #1797 (1.8.7/1.9.1)
* Fixed problem with reading `half` files where very small (denormalized)
half values could get squashed to float 0.0 instead of having their
values preserved, if certain old versions of libopenjpeg were being
used (because they set a CPU flag strangely upon library load and then
never changed it back, this is a libopenjpeg bug that has since been
fixed). #2048 (2.0)
* `-d chan=type` logic fixed for certain cases of specifying the data
types of individual channels. #2061 (2.0beta2)
* Expression evaluation: metadata names can now be enclosed in single
or double quotes if they don't follow "C" identifier naming conventions.
For example, `{TOP.'foo/bar'}` retrieves metadata called "foo/bar"
rather than trying to retrieve "foo" and divide by bar. #2068 (2.0beta2)
* Expression evaluation: When retrieving metadata, timecode data will be
expressed properly as a string ("00:00:00:00"). #2068 (2.0beta2)
* ImageBufAlgo:
* `color_map()` supports new maps "inferno", "magma", "plasma",
"viridis". #1820 (1.9.2)
* Across many functions, improve channel logic when combining an image
with alpha with another image without alpha. #1827 (1.9.2)
* `mad()` now takes an `img*color+img` variety. (Previously it
supported `img*img+img` and `img*color+color`.) #1866 (1.9.2)
* New `fit()` is like resize but fits inside a specified window size,
while preserving the aspect ratio of the image appearance. #1993.
* New `contrast_remap()` allows flexible linear or sigmoidal contrast
remapping. #2043 (1.9.4)
* `channel_append()` is no longer limited to requiring the two input
images to have the same pixel data type. #2022 (1.9.4)
* `isConstantColor()`, `isConstantChannel()`, and `isMonochrome()` have
added an optional `threshold` parameter that allows you to compute
whether the image is constant or monochrome within a non-zero
tolerance (the default is still 0.0, meaning checking for an exact
match). #2049 (2.0.0)
* `IBA::ociodisplay()` has better behavior when its "fromspace" parameter
is left blank -- instead of assuming "linear" (as a space name), it
assumes it's whatever space in your OCIO color config has the "linear"
role. #2083 (1.8.17/2.0.1)
* ImageBuf:
* Bug fixed in IB::copy() of rare types. #1829 (1.9.2)
* write() automatically tells the ImageCache to 'invalidate' the file
being written, so cached images will not retain the prior version of
the files. #1916 (1.9.2)
* Bug fix to ImageBuf::contains_roi() method -- it erroneously always
returned `true`. #1997 (1.8.14/1.9.4)
* ImageCache/TextureSystem/maketx:
* Improved stats on how long we wait for ImageInput mutexes.
#1779 (1.9.0/1.8.6)
* Improved performance of IC/TS tile and file caches under heavy
contention from many threads. #1780 (1.9.0)
* Increased the default `max_tile_channels` limit from 5 to 6.
#1803 (1.9.1)
* maketx: improved image hashing to avoid some (extremely rare) possible
hash collisions. #1819 (1.9.2)
* IC/TS performance improvements by changing the underlying hash table
implementation. #1823,1824,1825,1826,1830 (1.9.2)
* texture()/texture3d(): when requesting a nonexistent "subimage",
return the fill color, like we do when requesting nonexistent channels
(rather than nondeterministically simply not filling in the result).
#1917 (1.9.2)
* Relying on some changes to the ImageInput API, there is now much less
thread locking to protect the underlying ImageInputs, and this should
improve texture and image cache performance when many threads need
to read tiles from the same file. #1927 (1.9.2)
* `get_image_info()`/`get_texture_info()` is now more flexible about
retrieving arrays vs aggregates, in cases where the total number of
elements is correct. #1968 (1.9.4)
* Fix uninitialized read within the texture system (only affected
statistics, never gave wrong texture results). #2000 (1.9.4)
* texture3d() transforms lookup points from world into local space
if the file has a "worldtolocal" metadata giving a 4x4 matrix. #2009
(1.9.4)
* Fix minor texture filtering bug where widely disparate "sblur" and
"tblur" values could in some circumstances lead to incorrect texture
filter estimation. #2052 (2.0.0)
* `ImageCache::invalidate(filename)` did not properly invalidate the
"fingerprint" is used to detect duplicate files. #2081 (1.8.17/2.0.1)
* iv:
* Fix (especially on OSX) for various ways it has been broken since the
shift to Qt5. #1946 (1.8.12, 1.9.4)
* New optin `--no-autopremult` works like oiiotool, causes images with
unassociated alpha to not be automatically premultiplied by alpha
as they are read in. #1984 (1.9.4)
* All string->numeric parsing and numeric->string formatting is now
locale-independent and always uses '.' as decimal marker. #1796 (1.9.0)
* Python Imagebuf.get_pixels and set_pixels bugs fixed, in the varieties
that take an ROI to describe the region. #1802 (1.9.2)
* Python: Implement missing `ImageOutput.open()` call variety for declaring
multiple subimages. #2074 (2.0.1)
* More robust parsing of XMP metadata for unknown metadata names.
#1816 (1.9.2/1.8.7)
* Fix ImageSpec constructor from an ROI, display/"full" window did not get
the right default origin. #1997 (1.8.14/1.9.4)
* ImageSpec::erase_attribute() fix bug where it got case-sensitivity of the
search backwards when built using std::regex rather than boost::regex.
#2003 (1.8.14/1.9.4)
* DPX:
* Better catching of write errors, including filling the disk while in
the process of writing a DPX file. #2072 (2.0.1)
* Field3d:
* Prevent crashes when open fails. #1848 (1.9.2/1.8.8)
* Fix potential mutex deadlock. #1972 (1.9.4)
* GIF:
* Fix crash when reading GIF with comment extension but no comment data.
#2001 (1.8.14/1.9.4)
* JPEG:
* When writing, be robust to accidentally setting the "density" metadata
to values larger than JPEG's 16 bit integer field will accommodate.
#2002 (1.8.14/1.9.4)
* Better detection and reporting of error conditions while reading
corrupt JPEG files. #2073 (2.0.1)
* OpenEXR:
* Gracefully detect and reject files with subsampled channels,
which is a rarely-to-never-used OpenEXR feature that we don't support
properly. #1849 (1.9.2/1.8.8)
* Improved handling of UTF-8 filenames on Windows. #1941 (1.9.3, 1.8.12,
1.7.19)
* PNG:
* Fix redundant png_write_end call. #1910 (1.9.2)
* PSD:
* Fix parse issue of layer mask data. #1777 (1.9.2)
* RAW:
* Add "raw:HighlightMode" configuration hint to control libraw's
handling of highlight mode processing. #1851
* Important bug fix when dealing with rotated (and vertical) images,
which were not being re-oriented properly and could get strangely
scrambled. #1854 (1.9.2/1.8.9)
* Major rewrite of the way makernotes and camera-specific metadata are
handled, resulting in much more (and more accurate) reporting of
camera metadata. #1985 (1.9.4)
* The "oiio:ColorSpace" metadata is now set correctly when reading
raw DSLR images. And we deprecate the old "raw:ColorSpace" metadata,
which is useless. #2016 (1.9.4)
* Add "raw:aber" configuration hint to control libraw's adjustments for
chromatic aberration. This data is of type "float[2]", the first value
is the scale factor for red, the second for blue, and both should be
very close to 1.0. #2030 (1.9.4)
* TIFF:
* Improve performance of TIFF scanline output. #1833 (1.9.2)
* Bug fix: read_tile() and read_tiles() input of un-premultiplied tiles
botched the "shape" of the tile data array. #1907 (1.9.2/1.8.10)
* Improvement in speed of reading headers (by removing redundant call
to TIFFSetDirectory). #1922 (1.9.2)
* When config option "oiio:UnassociatedAlpha" is nonzero (or not set
-- which is the default), therefore enabling automatic premultiplication
by alpha for any unassociated alpha files, it will set the metadata
"tiff:UnassociatedAlpha" to indicate that the original file was
unassociated. #1984 (1.9.4)
* Bug fixes for TIFF reads of images with unassociated alpha -- there
were some edge cases where they pixels failed to automatically
premultiply upon read. #2032 (1.9.4)
* zfile: more careful gzopen on Windows that could crash when given bogus
filename. #1839,2070 (1.9.2/1.8.8/2.0.1)
* Windows fix: Safer thread pool destruction on. #2038 (1.9.4)
Build/test system improvements and platform ports:
* Fixes for Windows build. #1793, #1794 (1.9.0/1.8.6), #2025 (1.9.4)
* Fix build bug where if the makefile wrapper got `CODECOV=0`, it would
force a "Debug" build (required for code coverage tests) even though code
coverage is instructed to be off. (It would be fine if you didn't specify
`CODECOV` at all.) #1792 (1.9.0/1.8.6)
* Build: Fix broken build when Freetype was not found or disabled. #1800
(1.8.6/1.9.1)
* Build: Boost.Python is no longer a dependency, but `pybind11` is. If
not found on the system, it will be automatically downloaded. #1801, #2031
(1.9.1)
* Time for a multi-core build of OIIO is reduced by 40% by refactoring some
extra big modules into more bite-sized pieces. #1806 (1.9.2)
* testtex:
* Make the "thread workout" cases all honor `--handle`. #1778 (1.9.0)
* Only prints detailed stats if `-v` is used, and new option
`--invalidate` will invalidate the cache when starting each
threadtimes trial. #1828 (1.9.2)
* New `--anisoratio` lets you choose anisotropic shape for thread
working tests, and make thread_workout samples twice as big to be more
typical by interpolating mip levels. #1840 (1.9.2)
* TextureSystem stats are printed as well as ImageCache. #1840 (1.9.2)
* iv no longer requires GLEW, using QOpenGLFunctions instead. #1840 (1.9.2)
* DICOM: Fix dcmtk build errors on some platforms. Also, the minimum dcmtk
version we suport is 3.6.1. #1843 (1.9.2/1.8.8)
* Build fixes for Hurd OS. #1850 (1.9.2/1.8.8)
* Clean up leak sanitizer errors. #1855 (1.9.2)
* On Unix/Linux, add explicit DL library dependency to libOpenImageIO.so
itself instead of only to the binaries and test utilities.
#1860 (1.9.2/1.8.8)
* The build now bundles a sample OCIO config in testsuite/common so that we
can do OCIO-based unit tests. #1870 (1.9.2)
* Properly find newer openjpeg 2.3. #1871 (1.9.2)
* Fix testsuite to be Python 2/3 agnostic. #1891 (1.9.2)
* Removed `USE_PYTHON3` build flag, which didn't do anything. #1891 (1.9.2)
* The `PYTHON_VERSION` build variable is now better at selecting among
several installed versions of Python, and all the tests should work fine
with Python 3.x now. #2015 (1.9.4)
* Remove some lingering support for MSVS < 2013 (which we haven't advertised
as working anyway). #1887 (1.9.2)
* Windows/MSVC build fix: use the `/bigobj` option on some large modules
that need it. #1900, #1902 (1.8.10/1.9.2)
* Add up-to-date Nuke versions to FindNuke.cmake. #1920 (1.8.11, 1.9.2)
* Allow building against ffmpeg 4.0. #1926,#1936 (1.8.11, 1.9.2)
* Disable SSE for 32 bit Windows -- problematic build issues.
#1933 (1.9.3, 1.8.12, 1.7.19)
* Fixes to the `EMBEDPLUGINS=0` build case, which had at some point stopped
working properly. #1942 (1.9.3)
* Improvements in finding the location of OpenJPEG with Macports.
#1948 (1.8.12, 1.9.4)
* Improvement finding libraw properly on Windows. #1959 (1.9.4)
* Fix warnings to allow clean gcc8 builds. #1974 (1.9.4)
* Make sure we build properly for C++17. (1.9.4)
* Check properly for minimal FFMpeg version (2.6). #1981 (1.9.4)
* New build option GLIBCXX_USE_CXX11_ABI, when set to 0 will force the old
gcc string ABI (even gcc 7+ where the new ABI is the default), and if set
to 1 will force the new gcc string ABI (on gcc 5-6, where old ABI is the
default). If not set at all, it will respect the default choice for that
compiler. #1980 (1.9.4)
* TravisCI builds now use an abbreviated test matrix for most ordinary
pushes of working branches, but the full test matrix for PRs or pushes
to "master" or "RB" branches. #1983 (1.9.4)
* Support compilation by clang 7.0. #1995 (1.9.4)
* Support for building against OpenEXR 2.3. #2007 (1.9.4)
* Use OpenEXR pkgconfig if available. #2008 (1.9.4)
* Allow builds outside the source tree to pass testsuite. Defaults to
finding test image directories such as oiio-images, openexr-images, and
libtiffpic in the usual ".." from the main OIIO source directory, but now
it can be overridden with the CMake variable `OIIO_TESTSUITE_IMAGEDIR`.
#2026 (1.9.4)
* Remove stale python examples from `src/python`. They were untested,
undocumented, and probably no longer worked against the current APIs.
#2036 (1.9.4)
* Fixes for Windows when making Unicode builds, and fix Plugin::dlopen
on Windows to properly support UTF-8 filenames. #1454 (2.0.1)
* Support added for OpenCV 4.0. (2.0.1)
Developer goodies / internals:
* **Formatting with clang-format**: All submissions are expected to be
formatted using our standard clang-format rules. Please run
`make clang-format` prior to submitting code. The TravisCI tests include
one entry just to check that the formatting conforms, and will fail if it
doesn't, printing the diffs that would bring it to proper formatting.
(Note: for small changes, if you don't have clang-format locally, it's ok
to submit, then use the diffs from the failures to fix it by hand and
resubmit and update.) #2059,2064,2065,2067,2069.
* argparse.h:
* Add pre- and post-option help printing callbacks. #1811 (1.9.2)
* Changed to PIMPL to hide implementation from the public headers.
Also modernized internals, no raw new/delete. #1858 (1.9.2)
* array_view.h:
* Added begin(), end(), cbegin(), cend() methods, and new
constructors from pointer pairs and from std::array. (1.9.0/1.8.6)
* Deprecated, moved contents to span.h. You should change `array_view<T>`
to `span<T>` and `array_view<const T>` to `cspan<T>`. #1956 (1.9.4)
* color.h: add guards to make this header safe for Cuda compilation.
#1905 (1.9.2/1.8.10)
* filesystem.h:
* IOProxy classes that can abstract file operations for custom I/O
substitutions. #1931 (1.9.3)
* Proper UTF-8 filenames for unique_path() and temp_directory(), and
general UTF-8 cleanup/simplification. #1940 (1.9.3, 1.8.12, 1.7.19)
* Remove extraneous calls to exists() that were doubling the number
of stat syscalls. #2385 (2.1.8)
* fmath.h:
* Now defines preprocessor symbol `OIIO_FMATH_H` so other files can
easily detect if it has been included. (1.9.0/1.8.6)
* Modify to allow Cuda compilation/use of this header. #1888,#1896
(1.9.2/1.8.10)
* Improve numeric approximation of fast_atan() and fast_atan2().
#1943 (1.9.3)
* fast_cbrt() is a fast approximate cube root (maximum error 8e-14,
about 3 times faster than pow computes cube roots). #1955 (1.9.4)
* function_view.h: Overhauled fixed with an alternate implementation
borrowed from LLVM. (1.9.4)
* hash.h: add guards to make this header safe for Cuda compilation.
#1905 (1.9.2/1.8.10)
* imageio.h: `convert_image()` and `parallel_convert_image` have been
simplified to remove optional `alpha_channel` and `z_channel` parameters
that were never actually used. The old versions are still present but
are deprecated. #2088 (2.0.1)
* parallel.h:
* `parallel_options` passed to many functions. #1807 (1.9.2)
* More careful avoidance of threads not recursively using the thread
pool (which could lead to deadlocks). #1807 (1.9.2)
* Internals refactor of task_set #1883 (1.9.2).
* Make the thread pool better behaved in times if pool congestion -- if
there are already way too many items in the task queue, the caller may
do the work itself rather than add to the end and have to wait too
long to get results. #1884 (1.9.2)
* paramlist.h:
* ParamValue class has added get_int_indexed() and get_float_indexed()
methods. #1773 (1.9.0/1.8.6)
* ParamValue restructured to allow additional common data types to store
internally rather than requre an allocation. #1812 (1.9.2)
* New ParamList convenience methods: remove(), constains(),
add_or_replace(). #1813 (1.9.2)
* platform.h:
* New OIIO_FALLTHROUGH and OIIO_NODISCARD macros, and renamed
OIIO_UNUSED_OK to OIIO_MAYBE_UNUSED (to match C++17 naming). #2041
* simd.h:
* Fixed build break when AVX512VL is enabled. #1781 (1.9.0/1.8.6)
* Minor fixes especially for avx512. #1846 (1.9.2/1.8.8) #1873,#1893
(1.9.2)
* span.h:
* Used to be array_view. Now it's `span<>` and `span_strided`. Also,
`cspan<T>` is a handy alias for `span<const T>`. #1956 (1.9.4)
* Added begin(), end(), cbegin(), cend() methods, and new
constructors from pointer pairs and from std::array. (1.9.0/1.8.6)
* Added `==` and `!=` to span and span_strided. #2037 (1.9.4)
* strutil.h:
* All string->numeric parsing and numeric->string formatting is now
locale-independent and always uses '.' as decimal marker. #1796 (1.9.0)
* New `Strutil::stof()`, `stoi()`, `stoui()`, `stod()` functions for
easy parsing of strings to numbers. Also tests `Strutil::string_is_int()`
and `string_is_float()`. #1796 (1.9.0)
* New `to_string<>` utility template. #1814 (1.9.2)
* Fix to strtof, strtod for non-C locales. #1918 (1.8.11, 1.9.2)
* New `iless()` is case-insensitive locale-independent string_view
ordering comparison. Also added StringIEqual, StringLess, StringILess
functors. (1.9.4)
* `join()` is now a template that can act on any iterable container of
objects that allow stream output. #2033 (1.9.4)
* New `splits()`/`splitsv()` that direction returns a vector of
std::string or string_view, respectively. #2033 (1.9.4)
* A second version of `extract_from_list_string` that directly returns
a std::vector (instead of being passed as a param). #2033 (1.9.4)
* `parse_string` now accepts single quotes as well as double quotes
to enclose a quoted string. #2066 (2.0beta2)
* Fix Strutil::vsnprintf detection of encoding errors on Windows. #2082
(1.8.17/2.0.1)
* `parse_string()` - fix bugs that would fail for escaped quotes within
the string. #2386 (2.1.8)
* thread.h:
* Reimplementaiton of `spin_rw_mutex` has much better performance when
many threads are accessing at once, especially if most of them are
reader threads. #1787 (1.9.0)
* task_set: add wait_for_task() method that waits for just one task in
the set to finish (versus wait() that waits for all). #1847 (1.9.2)
* Fix rare crash in thread pool when lowering the number of threads.
#2013 (1.9.4/1.8.15)
* unittest.h:
* Made references to Strutil fully qualified in OIIO namespace, so that
`unittest.h` can be more easily used outside of the OIIO codebase.
#1791 (1.9.0)
* `OIIO_CHECK_EQUAL_APPROX` - fix namespace ambiguity. #1998 (1.9.4)
* `OIIO_CHECK_EQUAL` now can compare two `std::vector`s. #2033 (1.9.4)
* Make unit test errors respect whether stdout is a terminal when
deciding whether to print in color. #2045
* Extensive use of C++11 `final` and `override` decorators of virtual
methods in our internals, especially ImageInput and ImageOutput.
#1904 (1.9.2)
Notable documentation changes:
* A new THIRD-PARTY.md file reproduces the full open source licenses
of all code that we distribute with OIIO, incorporate, or derive code from.
They are have very similar license terms to the main OIIO license
("New BSD") -- MIT, Mozilla, Apache 2.0, or public domain. OIIO does not
use any GPL or other "viral" licenesed code that would change license
terms of any code that didn't come directly from those packages.
* The CHANGES.md file was getting truly enormous, so we have split the
release notes from the 0.x and 1.x releases into separate files found
in src/doc. So CHANGES.md only documents 2.0 and beyond.

-------------------------------------------------
* Improved finding LibRaw on Windows #1959
* Ensure FFMPEG (if found) is the minimum supported version 2.6. #1963
* Developer goodies: `intrusive_ptr<>` given a dangerous `release()`
method (use with caution). #1986
Release 1.8.12 (1 Jun 2018) -- compared to 1.8.11
-------------------------------------------------
* Build fix for 32 bit Windows -- disable SSE that was making trouble. #1933
* Improved UTF-8 filename support for OpenEXR filenames. #1941

* ImageCache and TextureSystem now have close(filename) and close_all()
methods, which for one file or all files will close the files and release
any open file handles (also unlocking write access to those files on
Windows), but without invalidating anything it knows about the ImageSpec
or any pixel tiles already read from the files, as would happen with a
call to the much more drastic invalidate() or invalidate_all(). #1950

frame numbers and ranges, also the `--frames` command line option is not
enough to trigger a loop over those frame numbers, even if no other
arguments appear to have wildcard structure. #1894
* TIFF bug fix: read_tile() and read_tiles() input of un-premultiplied tiles
botched the "shape" of the tile data array. #1907

* RAW: Important bug fix when dealing with rotated (and vertical) images,
which were not being re-oriented properly and could get strangely
scrambled. #1854
Release 1.8.8 (1 Feb 2018) -- compared to 1.8.7
-------------------------------------------------
* OpenEXR: gracefully detect and reject files with subsampled channels,
which is a rarely-to-never-used OpenEXR feature that we don't support
properly. #1849
* Field3d: Prevent crashes when open fails. #1848
* RAW: Add "raw:HighlightMode" configuration hint to control libraw's
handling of highlight mode processing. #1851

filename. #1839
* DICOM: Fix dcmtk build errors on some platforms. Also, the minimum dcmtk
version we suport is 3.6.1. #1843
* simd.h: Minor fixes especially for avx512. #1846
* iv: Drop GLEW and obsolete GL stuff from iv in favor of QOpenGLFunctions,
and fix broken pixelview text rendering. #1834
* On Unix/Linux, add explicit DL library dependency to libOpenImageIO.so
itself instead of only to the binaries and test utilities. #1860
* Build fixes for Hurd OS. #1850
Release 1.8.7 (1 Jan 2018) -- compared to 1.8.6
-------------------------------------------------
* All string->numeric parsing and numeric->string formatting is now
locale-independent and always uses '.' as decimal marker. #1796
* oiiotool outputs are now written to temporary files, then atomically moved
to the specified filename at the end. This makes it safe for oiiotool
to "overwrite" a file (i.e. `oiiotool in.tif ... -o out.tif`) without
problematic situations where the file is truncated or overwritten
before the reading is complete. #1797
* Python bindings for ImageBuf.get_pixels and set_pixels fixed some bugs
when passed an ROI without a channel range specified. #1802
* More robust parsing of XMP metadata for unknown metadata names. #1816
* strutil.h now includes a to_string<> utility template. #1814
Release 1.8.6 (1 Nov 2017) -- compared to 1.8.5
-------------------------------------------------
* oiiotool: Improved logic for propagating the pixel data format through
multiple operations, especially for files with multiple subimages.
#1769
* ImageCache/TextureSystem: improved stats on how long we wait for
ImageInput mutexes. #1779
* Build: Fix build bug where if the makefile wrapper got CODECOV=0, it would
force a "Debug" build (required for code coverage tests) even though code
coverage is instructed to be off. (It would be fine if you didn't specify
CODECOV at all.) #1792
* Build: minor fixes for Windows build. #1793, #1794
* Developers: The ParamValue class has added get_int_indexed() and
get_float_indexed() methods. #1773
* Developers: array_view added begin(), end(), cbegin(), cend() methods,
and new constructors from pointer pairs and from std::array.
* Developers: Fixed build break in simd.h when AVX512VL is enabled. #1781
* Developers: fmath.h now defined OIIO_FMATH_H so other files can easily
detect if it has been included.
* Build: Fix broken build when Freetype was not found or disabled. #1800
* Python: fixed missing exposure of RATIONAL enum value. #1799
Release 1.8 (1.8.5 - 1 Oct 2017) -- compared to 1.7.x
----------------------------------------------
New minimum dependencies:
* **C++11** (should also build with C++14 and C++17)
* **Compilers**: gcc 4.8.2 - gcc 7, clang 3.3 - 5.0, or MSVS 2013 - 2017
* **Boost >= 1.53** (tested up through 1.65)
* **CMake >= 3.2.2** (tested up through 3.9)
* **OpenEXR >= 2.0** (recommended: 2.2)
* (optional) **Qt >= 5.6**
* (optional) **Python >= 2.7** (3.x is also ok)
**Changes to install layout**: fonts now get installed to
`PREFIX/share/fonts/OpenImageIO`, OIIO docs now get installed to
`PREFIX/share/doc/OpenImageIO`, and the Python module gets installed to
`PREFIX/lib/pythonMAJ.MIN/site-packages`. #1747 #1760 (1.8.5)
Major new features and improvements:
* New oiiotool features:
* `--info:format=xml` format option requests what format the info
is printed. Current choices: `"text"`, `"xml"`. #1504 (1.8.0)
* `--info:verbose=1` verbose option make file info print full metadata,
but without needing to make other oiiotool operations verbose as would
happen with `--info -v`. #1504 (1.8.0)
* `--colormap` applies a color map based on the input values; the
map can be one of several named ones, or given explicitly with
numerical values. #1552 (1.8.1)
* `-i:type=...` lets you override the internal buffer type that will be
used for an input image. #1541 (1.8.1)
* `-i:ch=a,...` lets you restrict the input to only the listed channels.
This is semantically equivalent to following the input with a `--ch`
command, but by integrating into the input itself, it can sometimes
avoid using memory and I/O for unneeded channels. #1541 (1.8.1)
* `--echo STRING` prints the string to the console. This can contain
expressions! So you can do something like
oiiotool file.exr -echo "Size is {TOP.width}x{TOP.height}"
#1633 (1.8.3)
* `--eraseattrib REGEX` erases all metadata attributes from the top image
whose names match the regular expression. #1638 (1.8.3)
* `--text` takes new optional modifiers: `xalign=` (left, right, center)
and `yalign=` (baseline, top, bottom, center) to control how the text
is aligned to the (x,y) position specified, `shadow=` (default = 0)
than when nonzero controls the width of a "drop shadow" that makes the
text clearer when rendered on a background image of similar color.
#1646 (1.8.3)
* `--deepholdout` culls all samples that are farther away than the
opaque depth of a second holdout image. #1691 (1.8.4)
* New ImageBufAlgo functionality:
* `color_map()` applies a color map based on the input values; the
map can be one of several named ones, or given explicitly with
numerical values. #1552 (1.8.1)
* Added implementation of ImageBufAlgo::to_IplImage(). #1461 (1.7.9/1.8.1)
* `render_text()` has added parameters controlling text alignment and
drop shadows. #1646 (1.8.3)
* `deep_holdout()` culls all samples that are farther away than the
opaque depth of a second holdout image. #1691 (1.8.4)
* DICOM file format support (currently read-only). DICOM is the standard for
medical imaging data. Will only build if dependency "dcmtk" is found at
build time. #1534 (1.8.1)
* Experimental: The TextureSystem API has been extended to support batches
of texture lookups in a SIMD fashion. At present, only the new API was
added, a full implementation is in progress and may not be forthcoming
or reliable until 1.9. Even the API is experimental, and may change for
future releases. #1733 (1.8.5)
Public API changes:
* TypeDesc:
* Rational support: new 'semantic' hint RATIONAL and TypeDesc::Rational.
A rational is an int of aggregate VEC2 and hint RATIONAL, and should
be interpreted as val[0]/val[1]. #1698 (1.8.5)
* Added OIIO-scoped `static constexpr` versions of preconstructed
TypeDescs (e.g., `TypeFloat`). We are deprecating the ones that were
static data members of TypeDesc (e.g., TypeDesc::TypeFloat), they will
be removed in some future release. (1.8.5)
* ImageSpec:
* New `ImageSpec::serialize()` returns a string with a serialized version
of the contents of the ImageSpec. It may be text (human readable, like
is printed by `oiiotool -info -v`) or XML. #1504 (1.8.0)
* `ImageSpec` has a new constructor that accepts a `ROI` for image
dimensions and channels. #1646 (1.8.3)
* New `ImageSpec::channelspec()` retrieves the index of a named channel.
#1691 (1.8.4)
* New `ImageSpec::channelname(int)` safely retrieves the index of a named
channel. #1706 (1.8.5)
* ColorConig::createLookTransform() and createDisplayTransform() have been
extended to allow multiple key/value context pairs, by making them
comma-separated lists. The createColorProcessor() method has also been
extended to take context key/value pairs. #1542 (1.7.8, 1.8.0)
* `ImageBuf::read()` now has a variety that takes a channel range, allowing
you to populate an ImageBuf with a subset of channels in a file,
potentially saving memory and I/O for the unneeded channels. #1541 (1.8.1)
* Python: Fix unimplemented ImageBufAlgo.computePixelStats. #1596
(1.8.2/1.7.11)
* imageio.h: Fix incorrect declaration of declare_imageio_format().
#1609 (1.8.2/1.7.11)
* `ImageBuf::wrap_mode_from_string()` converts string wrap mode names
(such as "black") into `ImageBuf::WrapMode` enum values. #1615 (1.8.3)
* New `OIIO::getattribute()` queries:
* `"input_format_list"` and `"output_format_list"` return comma-separated
lists of all formats that support input and output, respectively.
#1577 (1.8.3)
* `"oiio:simd"` returns a comma-separated list of SIMD capabilities that
were enabled at build time, and `"hw:simd"` returns the list of
capabilities available on the currently running hardware. #1719 (1.8.5)
* `ImageBufAlgo::render_text()` API call has been overhauled, in addition
to new alignment and shadow aprameters, the color has changed from a raw
pointer to an `array_view<const float>` for better memory safety. Also,
it is now valid for the destination image to be uninitialized, in which
case it will be initialized to be just big enough for the text.
#1646 (1.8.3)
* DeepData:
* New `DeepData::opaque_z()` returns the depth value at which a pixel
becomes fully opaque. #1691 (1.8.4)
* New `DeepData::initialized()` and `allocated()` return whether the
DD is initialized and allocated, respectively. #1691 (1.8.4)
* `DeepData::split()` has been changed to return a `bool` indicating
whether any split occurred. #1691 (1.8.4)
* Remove some long-deprecated varieties of `ImageBufAlgo::colorconvert()`,
`ociolook()`, and `ociodisplay()`. #1695 (1.8.4)
* TypeDesc now allows specification of "rational" values, using a vec2i
(aggregate 2-vector of int) with a semantic hint of RATIONAL, i.e.,
`TypeDesc(INT, VEC2, RATIONAL)`, which is also aliased as
`TypeDesc::TypeRational`. The value is understood to be val[0]/val[1].
#1698 (1.8.5)
* ParamValueList::get_float will automatically convert rational values to
float. #1698 (1.8.5)
* The standard metadata "FramesPerSecond" has had its definition changed
from `float` to `rational`. Retrieving it as `float` should still work
as always. But apps and plugins that wish to treat it as a true rational
with no loss of precision are able to do so. This is only known to
directly affect the OpenEXR, GIF, and FFMPEG metadata. #1698 (1.8.5)
Fixes, minor enhancements, and performance improvements:
* oiiotool:
* `--chappend` resolves redundant channel names by using the subimage
name, if available. #1498 (1.8.0/1.7.8)
* `--mosaic` now gracefully handles the case of not having enough
images to completely fill the MxN matrix, with "left over" slots
black. #1501 (1.8.0/1.7.8)
* When command line arguments fail to parse properly, `oiiotool` will
exit with a non-zero shell status. #1540 (1.8.0)
* `--colorconvert`, `--ociodisplay`, and `--ociolook` can now take
multiple context key/value pairs (by allowing `key=` and `value=`
optional paramters be comma-separated lists). #1504 (1.8.0)
* Handle 'oiiotool --colorconvert X X' (transform from and to spaces that
are the same) without considering it an error. #1550 (1.8.0/1.7.8)
* Expression substitution now recognizes the following new metadata
names: MINCOLOR, MAXCOLOR, AVGCOLOR. An example use is to stretch
the value range of an image to fill the full [0-1] range:
oiiotool in.exr -subc {TOP.MINCOLOR} -divc {TOP.MAXCOLOR} -o out.exr
#1553 (1.8.1)
* `--fit:exact=1` use of the new `exact=1' option will perform the resize
to preserve exact aspect ratio and centering of the fit image to true
sub-pixel precision (at the possible risk of slight blurring,
especially of the edges), whereas the default (`exact=0`) will keep
the image sharper but round the size and offset to the nearest whole
pixel values. (1.8.1).
* `-i:type=...` optional modifier to `-i` forces a read of the input
file into a particular data type. #1541 (1.8.1)
* `-i:ch=...` optional modifier to `-i` specifies that only certain named
channels should be read from the file. Under extreme circumstances
when only a small subset of channels is needed from an image file with
many channels, this may improve speed and I/O. #1541 (1.8.1)
* Improved logic governing output data formats: non-cached inputs didn't
set default output data format correctly, and per-channel output
formats updated defaults when they shouldn't have. #1541 (1.8.1)
* `--diff` : in addition to the pixel coordinates and differences of the
biggest differing pixel, it now also prints the full values of all
channels of that pixel for both images. #1570 (1.8.1)
* `oiiotool -d` giving per-channel formats is no longer confused by
channel renaming with `--chnames`. #1563 (1.8.1/1.7.9)
* `--debug` nor prints the total runtime and peak memory use after each
individual op. #1583 (1.8.1)
* `-iconfig` not in all cases correctly propagate the input config
attribute to the file read. #1605 (1.8.2/1.7.11)
* Fixed `--crop`: it did not honor the `-a` flag to apply the crop to
all subimages. #1613 (1.8.2/1.7.11)
* In the case of runtime errors, `oiiotool` now echoes the entire command
line. This is helpful for debugging mangled oiiotool command lines
assembled by scripts. #1614 (1.8.3)
* Improved error reporting of file open errors when -iconfig is used.
#1626 (1.8.3/1.7.13)
* Expression evaluation now substitutes `FRAME_NUMBER` with the numeric
frame number for frame sequence wildcards, and `FRAME_NUMBER_PAD`
with the frame number 0-padded to the number of total digits specified
by the command line `--framepadding` argument. #1648 (1.8.3)
* `--resize` and `--resample` now have more intuitive behavior for images
where the display and pixel data windows are not the same, especially if
the data window had a nonzero origin (such as with crop or overscan).
#1667 (1.8.4/1.7.14)
* `--resample` has been extended to work for "deep" images. #1668
(1.8.4/1.7.14)
* `--deepmerge` now will give a useful error message when the image do
not have the same number of channels. #1675 (1.8.4/1.7.14)
* `--autocc` more gracefully handles unknown color spaces with a warning,
rather than a full error and termination. #1681 (1.8.4)
* `--resample` now takes an optional modifier `interp=0` to control
whether bilinear sample is used (default) or true closest-pixel point
sampling. #1694 (1.8.4)
* You can set rational metadata on the command line like this:
`oiiotool foo.exr --attrib:type=rational onehalf "50/100" -o rat.exr`
#1698 (1.8.5)
* `--fillholes` fixed a bug where, if asked to operate on an image with
nonzero origin (crop, overscan, shrink-wrap), it would incorrectly
move the pixels to the origin. #1768 (1.8.5)
* ImageBufAlgo:
* `channel_append()` resolves redundant channel names by using the
subimage name, if available. #1498 (1.8.0/1.7.8)
* `colorconvert()`, `ociodisplay()`, and `ociolook()` can now take
multiple context key/value pairs (by allowing they `context_key` and
`context_value` paramters be comma-separated lists). #1504 (1.8.0)
* `draw_rectangle()` (and `oiiotool --box`) wasn't drawing properly for
the degenerate case of a rectangle that takes up just one
pixel. #1601 (1.8.2)
* `resample()` has been extended to work for "deep" images.
#1668 (1.8.4/1.7.14)
* `deep_merge()` now will give a useful error message when the images do
not have the same number of channels. #1675 (1.8.4/1.7.14)
* `deep_merge()` performance has been greatly improved. #1739 (1.8.5)
* `resample()` fixed a subtle 1/2 pixel shift, now it more closely
aligns with `resize()`. #1694 (1.8.4)
* `fillholes_pushpull()` fixed a bug where, if asked to operate on an
image with nonzero origin (crop, overscan, shrink-wrap), it would
incorrectly move the pixels to the origin. #1768 (1.8.5)
* ImageBuf:
* Fix broken threads(n) method, which didn't correctly pass the right
number of threads along. #1622. (1.8.3/1.7.12)
* Copy constructor from another ImageBuf was previously broken for
IB's that wrap application buffers. #1665 (1.8.4/1.7.13)
* TextureSystem / ImageCache / maketx:
* `IC::get_image_info` (or `TS::get_texture_info`) queries for "channels"
on UDIM file patterns now succeed, returning the value for the first
matching file it finds. (N.B.: Relies on all textures within the same
UDIM set having the same nchannels.) #1502, #1519, #1530 (1.8.0/1.7.8)
* maketx: multiple simultaneous maketx process trying to create the same
texture will no longer clobber each other's output. #1525 (1.8.0/1.7.8)
* ImageCache: make robust to changes in autotile after opening and reading
from untiled files. #1566 (1.8.1/1.7.9)
* ImageCache: fix initialization bug that made the reported stats output
nonsensical in the numbers it gave for "redundant reads". #1567
(1.8.1/1.7.9)
* get_image_info queries of "displaywindow" and "datawindow" did not
correctly return a 'true' value when the data was found.
#1574 (1.8.1/1.7.9)
* maketx fix: two textures that had identical source pixels but differed
in whether they resized with "highlight compensation" incorrectly
ended up with identical hashes, and thus could be confused by the
TextureSystem at runtime into thinking they were duplicates. The hash
is now fixed. #1599 (1.8.2/1.7.11)
* Statistics no longer list as "BROKEN" files which were invalidated, or
files that were initialized with an ImageCacheFile but never opened.
#1655 (1.8.4)
* ImageCache::get_image_info() will now return a proper error (and not
hig an assertion) if asked for information about a subimage or MIP
level that does not exist in the file. #1672 (1.8.4/1.7.14)
* TextureSystem::get_texels fixes crashing behavior. #1669 (1.8.4/1.7.14)
* Big performance improvement on Windows with MSVC by removing certain
empty destructors in simd.h that was preventing MSVC from fully inlining
those classes. #1685 (1.8.4/1.7.15)
* maketx now supports `--colorconfig` option to explicitly point it to
an OpenColorIO config file, just like `oiiotool `--colorconfig`.
#1692 (1.8.4)
* Fix rare edge case crash in ImageCache. #1696 (1.8.4/1.7.15)
* Improved error messages for broken files. Specifically, it's much more
clear now when a file is broken because it's being rejected as a
texture because it's untiled or not MIP-mapped. #1751 (1.8.5)
* The maketx-generated metadata "oiio:SHA-1", "oiio:ConstantColor" and
"oiio:AverageColor" are ignored if the file has signs that it was not
directly generated by `maketx` or `oiiotool -otex` (specifically, if
it's not tiled, has no "textureformat" tag, or if its "software" tag
doesn't mention maketx or oiiotool). This helps for the case where a
maketx-generated file is loaded into PhotoShop (or otherwise altered),
saved with different pixel values but the old SHA-1, which would no
longer be valid and therefore cause the new file to be misidentified
as a duplicate texture even though it's not. #1762 (1.8.5)
* Bug fix to possible crashes when adding dither to tiled file output
(buffer size miscalculation). #1518 (1.8.0/1.7.8)
* Make sure that sRGB<->linear color transform still work (in the obvious
way) even when OpenColorIO is present but that its configuration for some
reason doesn't know about "sRGB" space. #1554 (1.8.1)
* Improved performance of input of many-channel files with differing
per-channel data formats. #1541 (1.8.1)
* `idiff` : in addition to the pixel coordinates and differences of the
biggest differing pixel, it now also prints the full values of all
channels of that pixel for both images. #1570 (1.8.1)
* ImageInput::read_tiles when only a channel subset is read, fixed case
with certain data sizes where the copy to user buffer got mangled.
#1595 (1.8.2/1.7.11)
* BMP:
* Add support for version 5 of the BMP format header. $1616 (1.8.3/1.7.12)
* FFMpeg/movies:
* "FramesPerSecond" metadata has had its type changed to rational.
#1709 (1.8.5)
* GIF:
* "FramesPerSecond" metadata has had its type changed to rational.
#1709 (1.8.5)
* IFF:
* Fix IFF output that didn't correctly save the "Author" and "Date"
metadata. #1549 (1.8.1/1.7.8)
* JPEG:
* Be more reslient to malformed Exif data blocks with bogus offsets
#1585 (1.8.1/1.7.10) and #1639 (1.8.3/1.7.13).
* When you ask the JPEG writer to output files with unsupported channel
counts (JFIF files only allow 1 or 3 channels), it will just silently
drop extra channels, rather than having a hard error. #1643 (1.8.3)
* OpenEXR:
* Fix global attribute "exr_threads" value, -1 should disable IlmImf's
thread pools as advertised. #1582 (1.8.1)
* Allow compression "none" for deep exr files. (1.8.2/1.7.11)
* Fixed input problem with sorting order of spectral alpha channels (RA,
GA, BA, or AR, AG, AB). #1674 (1.8./1.7.14)
* Can handle true rational metadata, including FramesPerSecond and
captureRate. #1698 (1.8.5)
* Fix problem with 2-channel images putting the channels in the wrong
order. #1717 (1.8.5/1.7.16)
* PNG: Better extraction of XMP from PNG files. #1689 (1.8.4)
* PSD:
* Support has been added for "cmyk", "multichannel", and "grayscale"
color modes. And support was fixed for rgb and grayscale 32 bit per
sample bit depth. #1641 (1.8.3/1.7.13)
* Fix issue for layer mask channels. #1714 (1.8.5)
* RAW:
* Fix possible crash when reading certain raw metadata. #1547 (1.7.8/1.8.0)
* The default value for missing "raw:use_camera_matrix" has been changed
to 1 (not 0) to better match default behavior of libraw/dcraw.
#1629 (1.8.3/1.7.13)
* Add support for selecting new demosaicing algorithms: "DMT" (mode 11)
and "AAHD" (mode 12). Renamed the "Modified AHD" to "AHD-Mod" to
simplify and match libraw terminology. Made matching of demosaicing
algorithms case-insensitive. #1629 (1.8.3/1.7.13)
* Support "ACES" color space for direct conversion while reading RAW
images (supported in libraw 0.18 or newer). #1626 (1.8.3/1.7.13)
* Add "raw:user_sat" configuration attribute to the reader.
#1666 (1.7.15/1.8.4)
* The pixels are now decoded (expensive) only when they are read, not
when the file is first opened. This makes raw reading much faster for
apps that are only interested in the metadata and not the pixel data.
#1741 (1.8.5)
* Unpack pixels when they are needed, not when the file is opened. This
makes it much faster to read RAW file only to extract the metadata,
if you don't need the pixel values. #1741 (1.8.5)
* RLA:
* Fix RLA reading and writing with certain channel orders and mixded data
formats. #1499 (1.8.0/1.7.8)
* TIFF:
* Fix to TIFF handling of certain unusual tags. #1547 (1.7.8/1.8.0)
* Now has a way to read raw pixel values from CMYK files, without
the automatic conversion to RGB (pass configuration attribute
"oiio:RawColor" set to nonzero). #1605 (1.8.2/1.7.11)
* Improved I/O of color separation images, particularly those with
custom InkSet attributes. #1658 (1.8.4/1.7.15)
* Fix typo that prevented correct reading of some Exif fields. #1625
(1.8.3/1.7.12)
* TIFF output omitted setting the "Make" and "Model" metadata tags.
#1642 (1.8.3/1.7.13)
* Images with fewer than 4 channels, but one of those channels was alpha,
were not correctly marking spec.alpha_channel. #1718 (1.8.5/1.7.16)
* The XPOSITION and YPOSITION tags are now interpreted as relative to
the RESOLUTIONUNIT, whereas before it was assumed to be measured in
pixels. We are confident that the new way is more in line with the
intent of the TIFF spec. #1631 (1.8.5)
* webp:
* Several new sanity checks prevent the webp reader from spending too
much I/O time and memory reading bogus files (malformed, corrupted,
or not a webp after all). #1640 (1.8.3/1.7.13)
* Nuke plugin: Fix txReader to properly restore saved MIP level knob value.
#1531 (1.8.0)
* Fixed several (so far unnoticed) buffer overruns and memory leaks.
#1591 (1.8.2)
* TIFF, JPEG, others: Improved reading Exif meatdata from XMP blocks, now it
does a better job of discerning the proper data types. #1627 (1.8.3/1.7.13)
* In several places, the formatting of date metadata has been changed to
have a leading zero rather than leading space for hours < 10, i.e.,
"02:00:00" rather than " 2:00:00". #1630 (1.8.3)
* Improve XMP parsing (for any format): for malformed XMP, still honor the
parts that could be parsed properly; recognize additinoal tags for
GPano (Google's Photo Sphere metadata schema) and camera raw (crs: prefix)
metadata; improve speed of XMP parsing. #1679 (1.8.4)
* Improved handling and color conversion of gamma-corrected images (DPX,
HDR, PNG, RLA, Targa) by supporting linearization correctly even in the
presence of OCIO configs that don't know about it. #1684 (1.8.4)
* Fixed static initialization order fiasco error involving interaction
between ColorConfig and Strutil. #1757 (1.8.5)
Build/test system improvements:
* **Changes to install layout**: fonts now get installed to
`prefix/share/fonts/OpenImageIO`, OIIO docs now get installed to
`prefix/share/doc/OpenImageIO`, and the Python module gets installed to
`prefix/lib/pythonMAJ.MIN/site-packages`. #1747 #1760 (1.8.5)

now use C++11 std::regex rather than boost regex. #1620,#1644 (1.8.3)
* Support for clang-tidy using build time flags CLANG_TIDY=1,
CLANG_TIDY_ARGS=..., and optionally CLANG_TIDY_FIX=1. #1649 (1.8.4)
* Fix Windows warnings about SIMD types as function arguments
and about bool vs int. #1659 (1.8.4)
* Changed the way namespaces work. Instead of a 2-level namespace, make a
one-level namespace, and automatically embed the major and minor version
in it. (Can stll override the basename.) #1662 (1.8.4)
* Fixes to OSX rpath behavior of linked binaries. #1671
* Upgraded the local PugiXML (when not using an external system version)
to release 1.8.1. #1679 (1.8.4)

* Simplify CMake scripts by using GNUInstallDirs to set standard installation
paths. #1747 (1.8.5)
Developer goodies / internals:
* Sysutil::Term formatting now works properly in Windows (though is only
functional for Windows 10 or above). (1.8.0/1.7.8) #1527
* C++11 idioms:
* We now eschew BOOST_FOREACH, in favor of C++11 "range for". #1535
* We now use std::unique_ptr, no longer use boost::scoped_ptr or
boost::scoped_array. #1543 (1.8.0) #1586 (1.8.1)
* Instead of the various boost components, we now use `std::` versions of
unordered_map, unordered_set, shared_ptr, hash, bind. #1586 (1.8.1)
* Change deprecated C headers (such as `<ctype.h>`) to C++ (`<cctype>`).
#1649 (1.8.4)
* Use `std::vector<>::emplace_back()` where applicable. #1657 (1.8.4)
* Mark ImageInput/ImageOutput derived classes as 'final'. (1.8.5)

* Added atomic_min and atomic_max. #1661 (1.8.4)
* Added atomic_fetch_add for `std::atomic<float>` and double. #1661 (1.8.4)
* Assume std::atomic is available, remove all code that is only needed
for pre-C++11. #1661 (1.8.4)
* benchmark.h:
* New `Benchmarker` class utility for micro-benchmarking. #1577 (1.8.5)
* Moved time_trial, timed_thead_wedge, DoNotOptimize, clobber_all_memory
to benchmark.h. #1577 (1.8.5)

* fmath.h:
* Fixed typo in fmath.h that made bitcast_to_float incorrect. #1543 (1.8.0)
* Templatize round_to_multiple() so it works with types other than `int`.
#1548 (1.8.0)
* `interpolate_linear()` utility linearly interpolates from a list of
evenly-spaced knots. #1552 (1.8.1)
* Slight reformulation of clamp() ensures sane results even with NaN
parameters. #1617 (1.8.3)
* Bug fixes to `ifloor()` and `floorfrac()`, which turned out to give
incorrect results for exact negative integer values. Also added
simd vector-based versions of `floorfrac`. #1766 (1.8.5)
* paramlist.h:
* ParamValueList has been refactored and now inherets from, rather than
containts, a `std::vector<ParamValue>`. This removes most of the
additional code from the class. #1677 (1.8.4)
* ParamValue new methods: `get<>()`, `get_int()`, `get_float()`,
`get_string()`, `get_ustring()` retrieve and convert. #1686 (1.8.4)
* ParamValueList new methods: `get_int()`, `get_float()`, `get_string()`,
`get_ustring()` search, retrieve, and convert (much like the
equivalent versions in ImageSpec did). #1686 (1.8.4)
* Remove the pointless typedefs `ImageIOParameter` and
`ImageIOParameterList` in favor of `ParamValue` and `ParamValueList`,
respectively. #1690 (1.8.4)
* platform.h:
* More `cpu_has_...()` tests for newer CPU capabilties. #1719 (1.8.5)
* Remove deprecated OIIO_NOTHROW macro, which should now simply be
C++11 `noexcept`. #1736 (1.8.5)
* strutil.h / Strutil:
* Add `Strutil::printf()` and `Strutil::fprintf()`, typesafe and
non-thread-jumbled replacements for C versions. #1579, #1656 (1.8.1, 1.8.4)
* `from_string<>` has been extended to 'unsigned int'. (1.8.3/1.7.13)
* `Strutil::parse_identifier_if` #1647 (1.8.3)
* safe_strcpy now takes a string_view, and more closely conforms to the
behavior of strncpy by filling in the extra space with 0 padding.
(1.8.5)
* simd.h:
* Add a matrix44 constructor from 16 floats. #1552 (1.8.1)

#1732 (1.8.5)
* Renamed `floori()` to `ifloor()` to match the analogous scalar function
in fmath.h. #1766 (1.8.5)
* strided_ptr.h: The `strided_ptr<>` template is now also templated on
the stride units -- the default is to measure strides in units of
sizeof(T), but it's possible to override and measure in bytes (the old
behavior). #1758 (1.8.5)
* thread.h:
* thread_pool class offers true persistent thread pool.
#1556, #1581 (1.8.1)
* Lots of C++ modernization of thread_group and spin_mutex. #1556 (1.8.1)
* Environment variable `OPENIMAGEIO_THREADS` can artificially raise or
lower the default number of threads (otherwise, it defaults to the
number of processor cores available). #1581 (1.8.1)
* timer.h: added timed_thread_widge() that benchmark code and prints
statistics about thread scaling. #1660 (1.8.4)
* typedesc.h:
* Modernized TypeDesc with C++11 constexpr where applicable. #1684 (1.8.4)
* New `TypeDesc::basevalues()` method. #1688 (1.8.4)
* unittest.h:
* Colored error messages and auto error return on completion. #1731 (1.8.5)
* *NEW* parallel.h:
* parallel_for, parallel_for_chunked, parallel_for_each offer simple
thread_pool-based parallel looping in 1 and 2 dimensions.
#1556, #1581 (1.8.1)
* Internal `OIIO::debugmsg()` call has been renamed to `OIIO::debug()`,
and setting env variable OPENIMAGEIO_DEBUG_FILE can redirect the debug
messages to a file. #1580 (1.8.1)
* Upgraded tinyformat to the latest master, also changed all the places
where we used TINYFORMAT_WRAP_FORMAT to use of C++11 variadic templates.
#1618 (1.8.3)
* *NEW* function_view.h : function_view<> is a very lightweight, non-owning,
generic callable object view. Cheaper than std::function, but the view
is not allowed to outlive the callable object it references. #1660 (1.8.4)
* Deprecate the pre-C++11 macros OIIO_CONSTEXPR, OIIO_CONSTEXPR_OR_CONST,
and OIIO_NOEXCEPT. #1678 (1.8.4)
Docs:
* Improve docs about deep IBA functions. (1.8.1)

* ImageCache and TextureSystem now have close(filename) and close_all()
methods, which for one file or all files will close the files and release
any open file handles (also unlocking write access to those files on
Windows), but without invalidating anything it knows about the ImageSpec
or any pixel tiles already read from the files, as would happen with a
call to the much more drastic invalidate() or invalidate_all(). #1950
Release 1.7.18 (1 May 2018) -- compared to 1.7.17
-------------------------------------------------
* Update to build against ffmpeg 4.0
Release 1.7.17 (1 Sep 2017) -- compared to 1.7.16

* Fix rare case TextureSystem crash. #1685
Release 1.7.14 (1 May 2017) -- compared to 1.7.13
-------------------------------------------------
* oiiotool expression substitution now recognizes FRAME_NUMBER and
FRAME_NUMBER_PAD. #1648
* oiiotool -resize and -resample now have more intuitive behavior for images
where the display and pixel data windows are not the same, especially if
the data window had a nonzero origin (such as with crop or overscan).
#1667
* oiiotool --resample and ImageBufAlgo::resample() have been extended to
work for "deep" images. #1668
* ImageCache::get_image_info() will now return a proper error (and not hit
an assertion) if asked for information about a subimage or MIP level that
does not exist in the file. #1672
* ImageBuf copy constructor from another ImageBuf was previously broken for
IB's that wrap application buffers. #1665
* TextureSystem::get_texels fixes crashing behavior. #1669
* Fixes to OSX rpath behavior of linked binaries. #1671
* OpenEXR file input: fixed problem with sorting order of spectral alpha
channels (RA, GA, BA, or AR, AG, AB). #1674
* ImageBufAlgo::deep_merge() (and oiiotool --deepmerge) now will give a
useful error message if you try to merge two deep images that do not have
the same number of channels. #1675
* ImageCache/TextureSystem statistics no longer list as "BROKEN" files which
were invalidated, or files that were initialized with an ImageCacheFile
but never opened. #1655
* Fix Windows warnings about SIMD types as function args, and about
int vs bool. #1659
Release 1.7.13 (1 Apr 2017) -- compared to 1.7.12
----------------------------------------------
* TIFF, JPEG, others: Improved reading Exif meatdata from XMP blocks, now it
does a better job of discerning the proper data types. #1627
* RAW: The default value for missing "raw:use_camera_matrix" has been changed
to 1 (not 0) to better match default behavior of libraw/dcraw. #1629

algorithms case-insensitive. #1629
* RAW: Support "ACES" color space for direct conversion while reading RAW
images (supported in libraw 0.18 or newer). #1626
* oiiotool: Improved error reporting of file open errors when -iconfig is
used. #1626
* oiiotool `--echo STRING` prints the string to the console. This can contain
expressions! So you can do something like
oiiotool file.exr -echo "Size is {TOP.width}x{TOP.height}"
#1633
* JPEG: Be more reslient to malformed Exif data blocks with bogus offsets.
#1585, #1639
* TIFF output omitted setting the "Make" and "Model" metadata tags. #1642
* webp: Several new sanity checks prevent the webp reader from spending too
much I/O time and memory reading bogus files (malformed, corrupted,
or not a webp after all). #1640
* PSD: Support has been added for "cmyk", "multichannel", and "grayscale"
color modes. And support was fixed for rgb and grayscale 32 bit per
sample bit depth. #1641
Release 1.7.12 (1 Mar 2017) -- compared to 1.7.11
----------------------------------------------
* BMP: add support for version 5 headers. #1616

Release 1.7.11 (1 Feb 2017) -- compared to 1.7.10
----------------------------------------------
* maketx fix: two textures that had identical source pixels but differed
in whether they resized with "highlight compensation" incorrectly
ended up with identical hashes, and thus could be confused by the
TextureSystem at runtime into thinking they were duplicates. The hash
is now fixed. (1599)
* OpenEXR: Allow compression "none" for deep exr files.
* Fix unimplemented python ImageBufAlgo.computePixelStats. (1596)
* IBA::draw_rectangle (and oiiotool --box) wasn't drawing properly for
the degenerate case of a rectangle that takes up just one
pixel. (1601)
* Fixed several (so far unnoticed) buffer overruns and memory leaks. (1591)
* ImageInput::read_tiles when only a channel subset is read, fixed case
with certain data sizes where the copy to user buffer got mangled. (1595)
* oiiotool -iconfig fixed, did not in all cases correctly propagate the
input config attribute to the file read. (1605)
* TIFF: now has a way to read raw pixel values from CMYK files, without
the automatic conversion to RGB (pass configuration attribute
"oiio:RawColor" set to nonzero). (1605)
* imageio.h: Fix incorrect declaration of declare_imageio_format(). (1609)
* `oiiotool --crop` did not properly honor the `-a` flag and apply the crop
to all subimages. (1613)
Release 1.7.10 (1 Jan 2017) -- compared to 1.7.9
----------------------------------------------
* Fix "exr_threads" value, -1 should disable IlmImf's thread pools. #1582

Release 1.7.9 (1 Dec 2016) -- compared to 1.7.8
----------------------------------------------
* Make sure that sRGB<->linear color transform still work (in the obvious
way) even when OpenColorIO is present but that its configuration for some
reason doesn't know about "sRGB" space. #1554
* ImageCache: make robust to changes in autotile after opening and reading
from untiled files. #1566
* ImageCache: fix initialization bug that made the reported stats output
nonsensical in the numbers it gave for "redundant reads". #1567
* IC/TS get_image_info queries of "displaywindow" and "datawindow" did not
correctly return a 'true' value when the data was found. #1574
* oiiotool -d giving per-channel formats is no longer confused by channel
renaming with --chnames. #1563
* Added implementation of ImageBufAlgo::to_IplImage(). #1461
Release 1.7.8 (1 Nov 2016) -- compared to 1.7.7
----------------------------------------------
* Fix gcc warnings when compiling for AVX2. #1511
* Fix a variety of Windows warnings and breaks. #1512, #1523
* Added support for new API introduced with ffmpeg 3.1. #1515
* Improve oiiotool --mosaic, wasn't reliably clearing the blank spaces
for missing images.
* Smarter channel_append channel renaming: try to resolve redundant
channel names by using the subimage name, if available. #1498
* Texture: get_image_info queries for "channels" on UDIM file patterns
now succeeds, returning the value for the first matching file it finds.
(Relies on all textures within the same UDIM set having the same
nchannels.) #1502, #1519
* Bug fix to possible crashes when adding dither to tiled file output
(buffer size miscalculation). #1518
* maketx: multiple simultaneous maketx process trying to create the same
texture will no longer clobber each other's output. #1525
* Build no longer gets confused about include files from older installations
of OIIO elsewhere on the system. #1524
* Improvements in finding OpenJPEG. #1520
* Sysutil::Term formatting now works properly in Windows (though is only
functional for Windows 10 or above). #1527
* Fix RLA reading and writing with certain channel orders and mixded data
formats. #1499
* Improved finding of OCIO headers. #1528
* Better recognition of C++11 features in MSVS.

(like size_t). #1548
* Fix IFF output that didn't correctly save the "Author" and "Date"
metadata. #1549
* Handle 'oiiotool --colorconvert X X' (transform from and to spaces that
are the same) without considering it an error. #1550
Release 1.7 (1 Oct 2016) -- compared to 1.6.x
----------------------------------------------
Major new features and improvements:
* New oiiotool commands:
* `-otex` and `-oenv` allow oiiotool to directly output proper texture

* `--deep_merge` does a full merge/composite of deep images. #1388 (1.7.2)
* `-i` inputs a file. Options `autocc=`, `now=`, `info=` control aspects
of reading that one file. #1389 (1.7.2)
* `--dilate` and `--erode` perform the basic morphological operations
of dilation and erosion. #1486 (1.7.5)
* New ImageBufAlgo functions: render_point(), render_line(), render_box()
#1319 (1.7.1); laplacian() #1332 (1.7.2); copy() #1388 (1.7.2);
deep_merge() #1388,1393 (1.7.2); dilate() and erode() (1.7.5).
* UDIM support for textures: filenames like `"tex_<UDIM>.exr"` will
automatically be resolved to the correct UTIM tile based on the s,t
coordinates. #1426 (1.7.3)
* Behavior change: When reading files without explicit channel names,
single channel images now name their channel "Y" (no longer "A",
which was confusing to algorithms that treat alpha in special ways).
Similarly, 2-channel images name their channels "R" and "G". #1434 (1.7.3)
Public API changes:
* DeepData internals and API overhaul: struct internals hidden, now you
must use the API; DeepData declaration is now in deepdata.h, not in
imageio.h; DD methods now allow insertion and erasure of individual
samples. #1289 (1.7.0) New DeepData methods: split, sort, merge_overlaps,
merge_deep_pixels, occlusion_cull. #1388,1393 (1.7.2)
* imageio.h: Removed items deprecated since 1.4: a version of convert_types()
that took alpha and z channel indices (but never used them). #1291
* fmath.h: Removed safe_sqrtf, safe_acosf, fast_expf, which have been
deprecated since 1.5. (1.7.0) #1291
* Removed ImageBufAlgo::flipflop(), which was deprecated since 1.5 and
is now called rotate180. #1291 (1.7.0)
* Several varieties of ImageCache and TextureSystem getattribute methods
were noticed to not be properly declared 'const'. This was fixed.
#1300 (1.7.0/1.6.9)
* For API calls that are deprecated but not yet removed, we now mark
them with deprecated attributes for compilers that support it,
meaning that you will get compile warnings and explanations when you
use deprecated OIIO API functions. #1313,#1318 (1.7.1)
* ImageBuf::contains_roi() reveals whether an ROI is completely contained
in the data region of the IB. #1310 (1.7.1)
* TypeDesc::is_signed() return true of the TypeDesc returns a type that
can represent negative values. #1320
* Python: improve: reading with request for type UNKNOWN returns native
data in an unsigned char array. Also, requesting HALF returns the half
bits in an unsigned short array (since there is no 'half' type in Python).
#1362 (1.7.2/1.6.11)
* Deprecate ImageCache/TextureSystem clear() methods, which never did
anything useful. #1347 (1.7.3)
* ImageSpec::set_format() clears any per-channel format information. #1446
(1.7.4)
* OIIO::getattribute("library_list", ...) can retrieve a list of all the
dependent libraries used when OIIO was built. #1458 (1.7.5)
* simd::mask4 class has been renamed simd::bool4 (though the old name
is still typedef'ed to work for now). #1484 (1.7.5)
* Python bindings for ImageBuf.reset() now properly understands the
argument names and default values. #1492 (1.7.6)
Fixes, minor enhancements, and performance improvements:
* oiiotool:
* oiiotool --subimage now takes as an argument either the subimage
numeric index, or a subimage name. #1287 (1.7.0)
* oiiotool's image cache was smaller than intended because of typo.
(1.7.0/1.6.9)
* Allow command-line expression metadata names to contain ':'. #1321
(1.7.1/1.6.10)
* --info more clearly prints info about subimage formats. #1320 (1.7.1)
* --ch: when the channels were only renamed, not reordered, the
renaming didn't happen properly. #1326 (1.7.1/1.6.10)
* Improved error message propagation from the underlying IBA functions
and from errors encounered during --stats. #1338 (1.7.2)
* --dumpdata:empty=0 now does something for non-deep files: skips
reporting of pixels where all channels are black. Also fixed errors
for dumpdata of deep, but non-float, files. #1355 (1.7.2/1.6.11)
* '--attrib:type=t name value' lets you explicitly name the top of
the attribute you're seting. This helps for ambiguous cases, and also
lets you create aggregate types (such as 'matrix' or 'int[2]' --
the value can be a comma-separated list in those cases). #1351 (1.7.2)
* --fixnan can now take option "error", meaning that upon finding a
NaN, the program considers it an error (rather than fixing).
#1351 (1.7.2)
* -o now takes optional arguments that control the output of just that
one file, including :datatype=, :bits=, :dither=, :autocc=,
:autocrop=, :autotrim=, :separate=, :contig=. #1351 (1.7.2)
* --resize and --fit sped up by approximately 2x. #1372 (1.7.2)
* --runstats not tracks and reports max memory usage. #1385 (1.7.2)
* New --cache and --autotile options let you set the ImageCache size and
autotile options. #1385 (1.7.2)
* --native results in slightly different behavior: does not force float,
but still uses the ImageCache as backing if the native data type
is one of the types directly supported by IC. #1385 (1.7.2)
* --fixnan now works with deep images. #1397 (1.7.3)
* --stats when used with deep images, if it encounters any nonfinite
values, will print the location of a representative one. #1397 (1.7.3)
* --add, --sub, and --absdiff, when its two image operands have differing
number of channels, now try to do the "correct" thing and have the
result have the larger number of channels, treating any "missing"
channels in either input as if they were 0-valued. #1402 (1.7.3)
* --attrib:type-timecode lets you set timecodes in "human-readable" form:
oiiotool in.exr -attrib:type=timecode TimeCode 11:34:03:00 -o out.exr
#1415 (1.7.3)
* -info -v will print timecodes in human-readable form. #1415 (1.7.3)
* Bug fix: --fullsize didn't work properly when followed by --attrib.
#1418 (1.7.3/1.6.14)
* Easily understandable warnings for common mistakes: no output specified,
an image that's modified but never output, or when -autocc causes
output to be a data format that overrides a previous -d directive.
#1419 (1.7.3)
* --origin, --croptofull, and --trim all do their thing to all subimages,
if the image at the top of the stack has multiple subimages.
#1440 (1.7.3)
* --crop operates on all subimages if either the -a flag was used, or
if the specific optinoal override `--crop:allsubimages=1` is used.
#1440 (1.7.3)
* --trim will trim all subimages to the same region, containing the
union of all nonzero pixels in all subimages. #1440 (1.7.3)
* --help now prints all of the dependent libraries for individual
formats. #1458 (1.7.5)
* Bug fix: make sure to propagate per-channel formats from input
to output. #1491 (1.7.6)
* -o:all=n will output all images currently on the stack, and the
filename argument will be assumed to be a pattern containing a %d,
which will be substituted with the index of the image (beginning with
n). For example, to take a multi-image TIFF and extract all the
subimages separately,
oiiotool multi.tif -sisplit -o:all=1 sub%04d.tif
will output the subimges as sub0001.tif, sub0002.tif, and so on.
#1494 (1.7.6)
* --mosaic MxN would fail mysteriously if the number of images on the
stack was less then M*N. This has been fixed to handle too-few images
gracefully and just leave blank spaces as needed. #1501 (1.7.7)
* ImageBuf:
* ImageBuf::iterator performance is improved -- roughly cutting in half
the overhead of iterating over pixels. #1308 (1.7.1/1.6.10)
* ImageBuf reads from disk have been improved substantially (in some
cases cutting read time in half) in many cases. #1328 (1.7.1)
* ImageBuf::copy_pixels() has been sped up. #1358 (1.7.2)
* ImageBufAlgo:
* The varieties of add(), sub(), mul(), and div() that take an
image operand and a per-channel constant operand have all been
modified to work properly for "deep" images. #1297 (1.7.0/1.6.10)
* mad() is sped up significantly (10x) for the common case of float
images already stored in memory (not cached). #1310 (1.6.1)
* render_point(), render_line(), render_box() can be used to render
points, lines, and boxes into an image. #1319 (1.7.1)
* channels(): when the channels were only renamed, not reordered,
the renaming didn't happen properly. #1326 (1.7.1/1.6.10)
* computePixelStats: Improved numerical accuracy to avoid getting
NaN values from imprecision. #1333 (1.7.2/1.6.11)
* laplacian() computes the laplacian of an image. #1332 (1.7.2)
* fixNonFinite() takes a new option: NONFINITE_ERROR, which will
return an error if nonfinite values are encountered. #1351 (1.7.2)
* convolve() and unsharp_mask() have been sped up by about 35% for
common cases. #1357 (1.7.2)
* IBA::resize sped up by approximately 2x. #1372 (1.7.2)
* IBA::fixNonFinite() now works with deep images. #1397 (1.7.3)
* dilate() and erode() perform basic morphological operations.
#1486 (1.7.5)
* ImageCache / TextureSystem:
* Less unnecessary pausing after read errors when falure_retries == 0.
#1336 (1.7.2/1.6.11)
* Texture: slight improvement in texture sharpness. #1369 (1.7.2/1.6.11)
* New statistics related to redundant tile reads. #1417 (1.7.3)
* TextureSystem option "flip_t", if nonzero, will flip the vertical
direction of all texture lookups. Use this for renderers that adhere
to the convention that the t=0 texture coordinate is the visible
"bottom" of the texture. #1428 (1.7.3) #1462 (1.7.5)
* UDIM support for textures: filenames like `"tex_<UDIM>.exr"` will
automatically be resolved to the correct UTIM tile based on the
s,t coordinates. #1426 (1.7.3)
* Avoid repeated broken texture error messages. #1423 (1.7.3)
* New IC/TS attribute: "max_errors_per_file" limits how many error
messages are printed for each file. #1423 (1.7.3)
* Improved statistics: for the "top 3" stats, print the top 3 that aren't
broken. Also print a count & list of broken/invalid files. #1433
(1.7.3/1.6.15)
* Add ability to retrieve various per-file statistics. #1438 (1.7.3/1.6.15)
* IC will clamp the max_open_files to the maximum allowed by the
system, so you can no longer crash a program by incorrectly
setting this limit too high. #1457 (1.7.5)
* IC/TS statistics now report separately the total size of images
referenced, in terms of in-cache data size, as well as on-disk
size (the latter may be compressed). #1481 (1.7.5)
* maketx:
* maketx -u now remakes the file if command line arguments or OIIO
version changes, even if the files' dates appear to match.
#1281 (1.7.0)
* Remove long-obsolete and non-functional command line options: --new,
--old, --hash. #1351 (1.7.2)
* iinfo:
* More clearly prints info about subimage formats. #1320 (1.7.1)
* Print timecodes in human-readable form. #1415 (1.7.3)
* ImageOutput: fix cases with native data but non-contiguous strides.
#1416 (1.7.3/1.6.15)
* Cineon:
* Improved deduction/setting of color space info. #1466 (1.7.5)
* GIF:
* GIF reader failed to set spec full_width, full_height. #1348
(1.7.2/1.6.11)
* JPEG:
* Fix bad memory access crash when reading specific JPEG files that were
written without their comment field including a null character to
end the string. #1365 (1.7.2/1.6.11)
* Change in behavior writing JPEG files when XResolution & YResolution
are not provided, but a PixelAspectRatio is requested. Previously, we
obeyed the JPEG/JFIF spec exactly, but it turns out that popular apps
including PhotoShop and Nuke use the field differently than the spec
dictates. So now we conform to how these apps work, rather than to
the letter of the spec. #1412 (1.7.3/1.6.15)
* OpenEXR:
* Fix broken multipart output when parts had different pixel data
types. #1306,#1316 (1.7.1/1.6.10)
* Improved error reporting for bad tile reads. #1338 (1.7.2/1.6.11)
* Fix errors reading tiles for mixed-format EXR files. #1352 (1.7.2/1.6.11)
* The global OIIO::attribute("exr_threads") has been modified so that 0
means to use full available hardware, -1 disables the OpenEXR
thread pool and execute in the caller thread. #1381 (1.7.2)
* When writing EXR, double check that there are no repeated channel
names, and if so, rename them so the data is not lost (since the
underlying libIlmImf will silently drop channels with repeated
names). #1435 (1.7.3)
* More robust detected of when OpenEXR is tiled (for weird files).
#1441 (1.7.3/1.6.15) (and a fix in #1448/1.7.4)
* Fixed minor bug with OpenEXR output with correctly setting
PixelAspectRatio based on the "XResolution" and "YResolution"
attributes. #1453 (Fixes #1214) (1.7.4/1.6.16)
* Fix setting "chromaticity" metadata in EXR files. #1487 (1.7.5)
* When writing OpenEXR, accept compression requests with quality numbers
appended to the compression algorithm name, such as "dwaa:200" to mean
dwaa compression with a dwaCompressionLevel set to 200. #1493 (1.7.6)
* PNG:
* Per the PNG spec, name 2-channel images Y,A. #1435 (1.7.3)
* Enforce that alpha premultiplication on output MUST consider alpha
to be the last channel of 2 or 4 channel images, no other cases
(as dictated by the PNG spec). #1435 (1.7.3)
* PNM:
* Fixed byte swapping when reading 16 but PNM files. #1352 (1.7.2/1.6.11)
* RAW:
* Changes to how we instruct libraw to process images when reading:
Now, by default, auto-bright adjustment is off, camera white
balance is on, and maximum threshoding is set to 0. There are
"open with config" overrides for all of these, for anybody who
doesn't like the default. #1490 (1.7.6)
* RLA:
* Fixes for both reading and writing of RLA images that are cropped
(i.e., data window is a subset of display window). #1224 (1.7.0/1.6.10)
* TIFF:
* When outputting a TIFF file, a special attribute "tiff:half", if
set to nonzero, will enable writing of 16-bit float pixel data
(obviously, only if the spec.format is HALF). #1283 (1.7.0)
* TIFF input: erase redundant IPTC:Caption and IPTC:OriginatingProgram
if they are identical to existing ImageDescription and Software
metadata, respectively. (1.7.0/1.6.9)
* Output: "tiff:zipquality" attribute controls time-vs-quality for
ZIP compression (1-9, defualt 6, higher means more compression).
#1295 (1.7.1)
* Fix typo that made TIFF files incorrectly name color space metadata
"oiio::ColorSpace" instead of "oiio:ColorSpace". #1394 (1.7.2)
* More robust handling of non-zero origin of full/display window.
#1414 (1.6.14/1.7.3)
* Video formats:
* The ffmpeg-based reader had a variety of fixes. #1288 (1.7.0)
* Support for reading 10-bit and 12-bit movies. #1430 (1.7.5)
* Improved accuracy of "lanczos3" filter; speed up blackman-harris filter.
#1379 (1.7.2)
* Speed up linear<->sRGB color conversions (as used by any of the IBA color
conversion functions as well as oiiotool --colorconvert and friends),
approximately doubling the speed when no OpenColorIO config is found.
#1383 (1.7.2)
* ImageInput::create() and ImageOutput::create() will now gracefully
handle unexpected exceptions inside an ImageInput or ImageOutput
constructor -- return an error rather than crashing. #1456 (1.7.4/1.6.16)
* Nuke txWriter adds UI to let you choose which type of texture you are
building (ordinary 2D texture, latlong env map, etc). #1488 (1.7.6)
Build/test system improvements:
* Default build is now C++11! #1344 (1.7.2) You can still (for now) build
for C++03 using 'make USE_CPP11=0' or 'cmake -DOIIO_BUID_CPP11=0', but
some time soon we will be C++11 minimum.
* Fix build break against Boost 1.60. #1299,#1300 (1.7.0/1.6.9/1.5.23)
* filesystem_test now much more comprehensively tests the contents of
Filesystem. #1302 (1.7.0)
* fmath_test adds benchmarks for various data conversions. #1305 (1.7.0)
* Travis: add DEBUG builds to the matrix to fix any warnings or failures
that only show up for DEBUG builds. #1309 (1.7.1/1.6.10)
* Fix build issues on some platforms for SHA1.h, by adding proper include
of `<climits>`. #1298,#1311,#1312 (1.7.1/1.6.10)
* Cleanup of include logic in simd.h that fixed build problems for gcc < 4.4.
#1314 (1.7.1/1.6.10)
* Fix build breaks for certain 32 bit platforms. #1315,#1322 (1.7.1/1.6.10)
* imagespeed_test can not specify the data conversion type for reads,
can optionally allow skipping the IB iteration tests, and can set the
IC tile cache size. #1323 (1.7.1)
* Fix build breaks for gcc 6. #1339 (1.7.2/1.6.11) #1436 (1.7.3/1.6.15)
* Fix errors in finding the correct locaiton of pugixml.hpp when using
USE_EXTERNAL_PUGIXML=1. #1339 (1.7.2/1.6.11)
* Rewrite of FindOpenEXR.cmake. Solves many problems and is simpler.
No more FindIlmbase.cmake at all. #1346 (1.7.2/1.6.11)
* 'make CODECOV=1; make CODECOV=1 test' can build and test in a way that
provides a code coverage report. #1356 (1.7.2)
* Fix Filesystem::open() issues with UTF-8 filenames on MinGW.
#1353,#1357 (1.7.2/1.6.11)
* Allow build against a wider range of ffmpeg versions. #1359 (1.7.2)
* Build correctly against FFMPEG 3.0. #1374 (1.7.2)
* If found, libjpeg-turbo is used rather than libjpeg; this gives about a
2x speed improvement for reading & writing JPEG files. #1390 (1.7.2/1.6.13)
* USE_CPP11=... and USE_CPP14=... are the build flags for both the Make
wrapper and the CMake scripts. (Before, it was confusing to have USE_CPP11
for make but OIIO_BUILD_CPP11 for CMake. Now they are one.) #1391 (1.7.2)
* Improved LINKSTATIC=1, now mostly works. #1395 (1.7.3)
* Big CMake refactor, got rid of redundancies. #1395 (1.7.3)
* Remove old embedded Ptex, now must find Ptex externally. Also modified
the build scripts to correctly handle newer versions of Ptex. #1400
(1.7.3/1.6.13)
* Got Appveyor building OIIO. This is a continuous integration service
much like Travis, but it's for Windows. Hopefully this means that it will
be much harder for us to make changes that inadvertently break the build
on Windows. #1399 (1.7.3)
* Make FindOpenEXR.cmake more robust when the version number is embedded
in the library name. #1401 (1.7.3/1.6.15)
* Clear up some inconsistencies in the CMake files and the Makefile wrapper:
the flag to compile with libc++ is now always called USE_LIBCPLUSPLUS,
not sometimes OIIO_BUILD_LIBCPLUSPLUS. #1404 (1.7.3)
* Overhaul OpenCV dependency finding and make it work with OpenCV 3.x.
#1409 (1.7.3/1.6.13)
* Allow custom JPEG_PATH to hint location of JPEG library. #1411
(1.7.3/1.6.13)
* Windows UTF-8 filename safety fixes. #1420 (1.7.3/1.6.14)
* Various Windows compilation & warning fixes. #1443 (1.7.3/1.6.15)
* Now builds correctly against OpenJPEG 2.x, it previously only supported
OpenJPEG 1.x. #1452 (Fixes #957, #1449) (1.7.4/1.6.16)
* Fix Filesystem::searchpath_find on Windows with UTF-8 paths.
#1469 (1.7.51.6.17)
* Improved the way OpenEXR installations are found. #1464 (1.7.5)
Developer goodies / internals:
* thread.h has had all the atomic operations split into a separate atomic.h.
#1443 (1.7.3)
* atomic.h: add atomic and, or, and xor. #1417 (1.7.2/1.6.14);
* parallel_image has been improved in several ways: can choose split
direction; raised minimum chunk size to prevent thread fan-out for
images too small to benefit; uses the calling thread as part of the
pool. #1303 (1.7.0)
* timer.h: DoNotOptimize() and clobber_all_memory() help to disable certain
optimizations that would interfere with micro-benchmarks. #1305 (1.7.0)
* simd.h improvements: select(); round(); float4::store(half*),
int4::store(unsigned short*), int4::store(unsigned char*). #1305 (1.7.0)
Define insert, extract, and ^ (xor), and ~ (bit complement) for mask4,
and add ~ for int4. #1331 (1.7.2); madd, msub, nmadd, nmsub, rint,
andnot #1377 (1.7.2); exp, log #1384 (1.7.2); simd::float3 is like float4,
but only loads and stores 3 components, it's a good Vec3f replacement (but
padded) #1473 (1.7.5); matrix44 4x4 matrix class #1473 (1.7.5);
mask4 renamed to bool4, and addition of float8, int8, bool8 classes
for 8-wide AVX/AVX2 SIMD #1484 (1.7.5).
* fmath.h: convert_types has new special cases that vastly speed up
float <-> uint16, uint8, and half buffer conversions #1305 (1.7.0);
ifloor (1.7.2); SIMD versions of fast_log2, fast_log, fast_exp2,
fast_exp, fast_pow_pos #1384 (1.7.2); fix sign of expm1 for small
arguments #1482 (1.7.5); added fast_log1p #1483 (1.75).
* Fix pesky precision discrepancy in internal convert_type<> that used
slightly different math when converting one value at a time, versus
converting whole arrays. #1350 (1.7.2)
* thread.h: add mutex_pool #1425 (1.7.3/1.6.15)
* compute_test: new unit test can be used to benchmark computation
times. #1310 (1.7.1)
* filesystem.h: Filesystem::file_size() returns file size in bytes;
Filesystem::read_bytes() reads the first n (or all) bytes from a file
into a buffer. #1451 (1.7.4/1.6.16)
* strutil.h: Strutil::extract_from_list_string is more flixible by
allowing the vals list to start empty, in which case it will add as
many values as it finds rather than only replacing existing
values #1319 (1.7.1); Strutil::replace #1422 (1.7.3/1.6.15);
utf_to_unicode now takes a string_view rather than a std::string&
#1450 (1.7.4); add Strutil::base64_encode() #1450 (1.7.4).
* sysutil.h: Sysutil::getenv() safely gets an env variable as a string_view
#1451 (1.7.4/1.6.16); terminal_columns() now has a correct implementation
on Windows #1460 (1.7.5); max_open_files() retrieves the maximum number
of files the process may open simultaneously #1457 (1.7.5).
* platform.h: better distinguishing beteen Apple and Generic clang,
separately set OIIO_CLANG_VERSION and OIIO_APPLE_CLANG_VERSION. Also change
OIIO_GNUC_VERSION to 0 for clang, only nonzero for true gcc. #1380 (1.7.2)
* ImageCache: remove unused shadow matrix fields, save space. #1424 (1.7.3)
* Many documentation files (such as README, CHANGES, LICENSE, CREDITS,
and INSTALL) have been changed from plain text to MarkDown. #1442 (1.7.3)
* Sysutil::Term class makes it easy to use color output on the terminal.
#1479 (1.7.5)

is not an issue for exr 2.x). #1448
* Now builds correctly against OpenJPEG 2.x, it previously only supported
OpenJPEG 1.x. #1452 (Fixes #957, #1449)
* New utility functions: Sysutil::getenv(), Filesystem::file_size(),
FileSystem::read_bytes(). #1451
* Fixed minor bug with OpenEXR output with correctly setting
PixelAspectRatio based on the "XResolution" and "YResolution"
attributes. #1453 (Fixes #1214)
* Gracefully handle unexpected exceptions inside an ImageInput or
ImageOutput constructor -- return an error rather than crashing.
#1456
Release 1.6.15 (released 1 Jul 2016 -- compared to 1.6.14)
------------------------------------------------
* Improved statistics: for the "top 3" stats, print the top 3 that aren't
broken. Also print a count & list of broken/invalid files. #1433
* Change in behavior writing JPEG files when XResolution & YResolution
are not provided, but a PixelAspectRatio is requested. Previously, we
obeyed the JPEG/JFIF spec exactly, but it turns out that popular apps
including PhotoShop and Nuke use the field differently than the spec
dictates. So now we conform to how these apps work, rather than to
the letter of the spec. #1412
* IC/TS: add ability to retrieve various per-file statistics. #1438
* Windows UTF-8 filename safety fixes. #1420
* ImageOutput: fix cases with native data but non-contiguous strides. #1416
* Make FindOpenEXR.cmake more robust when the version number is embedded
in the library name. #1401
* Fix build breaks for gcc 6. #1339 (1.7.2/1.6.11) #1436
* More robust detected of when OpenEXR is tiled (for weird files). #1441
* Various Windows compilation and warning fixes.
* strutil.h: added replace(). #1422
* thread.h: added mutex_pool. #1425
Release 1.6.14 (released 1 Jun 2016 -- compared to 1.6.13)
------------------------------------------------
* More robust handling of TIFF I/O when non-zero origin of full/display
window. (#1414)
* oiiotool --fullsize didn't work properly when followed by --attrib. (#1418)
Release 1.6.13 (released 1 May 2016 -- compared to 1.6.12)
------------------------------------------------
* Use libjpeg-turbo if found. It's a drop-in replacement for libjpeg, but
is around 2x faster. #1390
* Fix some Windows compiler warnings and errors.
* Remove old embedded Ptex, now must find Ptex externally. Also modified
the build scripts to correctly handle newer versions of Ptex. #1400
* Overhaul OpenCV dependency finding and make it work with OpenCV 3.x. #1409
* Allow custom JPEG_PATH to hint location of JPEG library. #1411
Release 1.6.12 (released 1 Apr 2016 -- compared to 1.6.11)
------------------------------------------------
* Build correctly against FFMPEG 3.0. #1374
* The global OIIO::attribute("exr_threads") has been modified so that 0
means to use full available hardware, -1 disables the OpenEXR thread
pool and execute in the caller thread. #1381
* Thread-pool counts initialized to hardware_concurrency, not
physical_concurrency (i.e., they will include hyperthread cores by
default). #1378
* oiiotool --autocc bug fixed.
* Miscellaneous improvements to simd.h ported from master.
* Fix typo that made TIFF files incorrectly name color space metadata
"oiio::ColorSpace" instead of "oiio:ColorSpace". #1394
Release 1.6.11 (released 1 Mar 2016 -- compared to 1.6.10)
------------------------------------------------
* Fix potential of IBA::computePixelStats (including oiiotool --stats)
to end up with NaNs due to numerical imprecision. #1333
* Less unnecessary pausing after read errors when falure_retries == 0.
#1336
* Fix errors in finding the correct locaiton of pugixml.hpp when using
USE_EXTERNAL_PUGIXML=1. #1339
* Fix build breaks for gcc 6. #1339
* GIF reader failed to set spec full_width, full_height. #1348
* PNM: Fixed byte swapping when reading 16 but PNM files. #1352
* OpenEXR: Improved error reporting for bad tile reads. #1338
* OpenEXR: Fix errors reading tiles for mixed-format EXR files. #1352
* oiiotool --dumpdata:empty=0 now does something for non-deep files: skips
reporting of pixels where all channels are black. Also fixed errors
for dumpdata of deep, but non-float, files. #1355
* Fix Filesystem::open() issues with UTF-8 filenames on MinGW. #1353
* Rewrite of FindOpenEXR.cmake. Solves many problems and is simpler.
No more FindIlmbase.cmake at all. #1346
* Fix build break for older gcc < 4.4 that didn't have immintrin.h.
* Fix bad memory access crash when reading specific JPEG files that were
written without their comment field including a null character to
end the string. #1365
* The ffmpeg-based reader had a variety of fixes. #1288
* Python: improve: reading with request for type UNKNOWN returns native
data in an unsigned char array. Also, requesting HALF returns the half
bits in an unsigned short array (since there is no 'half' type in Python).
#1362
* Texture: slight improvement in texture sharpness. #1369
* Update webp testsuite references for new webp version.
Release 1.6.10 (released 1 Feb 2016 -- compared to 1.6.9)
------------------------------------------------
* ImageBufAlgo add, sub, mul, and div, for the varieties that combine
an image with a (per-channel) constant, now work for "deep" images.
#1257
* ImageBuf::iterator performance is improved -- roughly cutting in half
the overhead of iterating over pixels. #1308
* OpenEXR: Fix broken multipart output when parts had different pixel
data types. #1306,#1316
* Allow oiiotool command-line expression metadata names to contain ':'.
* Fix oiiotool --ch (or IBA::channels) when the channels were only renamed,
not reordered, the renaming didn't happen properly. #1326
* Fixes for both reading and writing of RLA images that are cropped
(i.e., data window is a subset of display window). #1224
* Fix build issues on some platforms for SHA1.h, by adding proper include
of `<climits>`. #1298,#1311,#1312
* Cleanup of include logic in simd.h that fixed build problems for gcc < 4.4.
#1314
* Fix build breaks for certain 32 bit platforms. #1315,#1322
Release 1.6.9 (released 5 Jan 2016 -- compared to 1.6.8)
------------------------------------------------
* Several varieties of ImageCache and TextureSystem getattribute methods
were noticed to not be properly declared 'const'. This was fixed.
#1300 (1.6.9)
* Fix build break against Boost 1.60. #1299,#1300 (1.6.9/1.5.23)
* The Python bindings for ImageCache was overhauled after several
of the methods were found to be horribly broken. #1300 (1.6.9)
* oiiotool --subimage now allows a subimage name as argument, as well
as the numeric index. #1271,#1287 (1.6.9)
* TIFF input: erase redundant IPTC:Caption and IPTC:OriginatingProgram
if they are identical to existing ImageDescription and Software metadata,
respectively. (1.6.9)
* Fix oiiotool image cache smaller than intended because of typo. (1.6.9)
Release 1.6 (1.6.8 released Dec 21, 2015 -- compared to 1.5.x)
----------------------------------------------
Major new features and improvements:
* New oiiotool functionality:
* Expression evaluation/substitution on the oiiotool command line.
Anything enclosed in braces { } in a command line argument will be
substituted by the evaluation of the enclosed expression. Expressions
may be numbers, simple arithmetic (like 'expr+expr'), or retrieving
image metadata from named images or images on the stack.
Please see the PDF documentation, Section 12.1 for details and
examples.
* --absdiff, --absdiffc compute the absolute difference (abs(A-B)) of
two images, or between an image and a constant color. #1029 (1.6.0)
* --abs computes the absolute value of an image. #1029 (1.6.0)
* --div, divc divide one image by another (pixel by pixel), or divides
the pixels of an image by a constant color. #1029 (1.6.0)
* --addc, --subc, --mulc, --powc are the new names for --cadd, --csub,
--cmul, and --cpow. The old ones will continue to work but are
considered depcrected. #1030 (1.6.0)
* --pattern supports new patterns: "fill" makes a solid, vertical or
horizontal gradient, or four-corner interpolated image (just like
the --fill commmand) (1.6.0); "noise" can generate uniform, gaussian,
or salt & pepper noise (1.6.2).
* --fill, in addition to taking optional parameter color=... to give a
solid color for the fill region, now also takes top=...:bottom=... to
make a vertical gradient, left=...:right=... to make a horizontal
gradient, and topleft=...:topright=...:bottomleft=...:bottomright=...
to make a 4-corner gradient. (1.6.0)
* --noise adds noise to the current image: additive uniform or gaussian
noise, or making "salt & pepper" noise. (1.6.2)
* --trim crops the image to the minimal rectangle containing all
the non-0 pixels. (1.6.3)
* --autocc : when turned on, automatic color conversion of input files
into a scene_linear space, and conversion to an appropriate space
and pixel type upon output. It infers the color spaces based on
metadata and filenames (looking for OCIO-recognized color space names
as substrings of the filenames). #1120 (1.6.3)
* --mad takes three image arguments, multiplies the first two and then
adds the third to it. #1125 (1.6.3)
* --invert computes the color inverse (1-value) for color channels.
#1125 (1.6.3)
* --colorconfig allows you to specify a custom OCIO configuration file
(rather than strictly relying on the $OCIO env variable). #1129 (1.6.3)
* --deepen converts flat images to "deep". #1130 (1.6.3)
* -n (no saved output) performs all calculations (including timing and
stats) but does not write any output files to disk. #1134 (1.6.3)
* --debug prints debugging information, this is now separate from
-v which just makes more verbose (non-debugging) output. #1134 (1.6.3)
* --pixelaspect rescales the image to have the given pixel aspect
ratio. #1146 (1.6.5)
* --ociofiletransform() implements OpenColorIO "file" transforms.
#1213 (1.6.5)
* New ImageBufAlgo functions:
* absdiff() computes the absolute difference (abs(A-B)) of two images,
or between an image and a constant color. #1029 (1.6.0)
* abs() computes the absolute value of an image. #1029 (1.6.0)
* div() divides one image by another (pixel by pixel), or divides all
the pixels of an image by a constant color. #1029 (1.6.0)
* fill() has been extended with new varieties that take 2 colors (making
a vertical gradient) and 4 colors (one for each ROI corner, for a
bilinearly interpolated gradient). (1.6.0)
* noise() injects noise into an image -- uniform, gaussian/normal,
or salt & pepper noise. (1.6.2)
* mad() multiplies the first two arguments and then adds the third to
it. #1125 (1.6.3)
* invert() computes 1-val. #1125 (1.6.3)
* deepen() turns a flat RGBA (and optional Z) image into a "deep"
image. #1130 (1.6.3)
* ociofiletransform() implements OpenColorIO "file" transforms.
#1213 (1.6.5)
* Some open source fonts are now distributed with OIIO (DroidSans,
DroidSans-Bold, DroidSerif, DroidSerif-Bold, DroidSerif-Italic,
DroidSerif-BoldItalic, and DroidSansMono), and so those are always
available to ImageBufAlgo::render_text() and oiiotool --text, on all
platforms and even if you don't have any other installed fonts on
your system. DroidSans is now the default font. #1132 (1.6.3)
* GIF output support (including writing animated GIF images, just write it
as a multi-subimage file). For example, this works:
oiiotool foo*.jpg -siappendall -attrib FramesPerSecond 10.0 -o anim.gif
#1193 (1.6.4)
Public API changes:
* TypeDesc:
* New helper methods: is_array(), is_unsized_array(), is_sized_array().
#1136 (1.6.3)
* New constructor and fromstring of a string_view, in addition to
the old versions that took char*. #1159 (1.6.4/1.5.16)
* New aggregate type: MATRIX33. #1265,#1267 (1.6.6)
* ImageSpec:
* ImageSpec::metadata_val() is now static, rather than simply const,
since it doesn't need access to *this at all. #1063 (1.6.1)
* Added a new variety of find_attribute that takes a temporary
ImageIOParameter as scratch space. The advantage of this call is
that it can retrieve items from the named ImageSpec fields, such
as "width", "full_x", etc. Also, the get_int_attribute,
get_float_attribute, and get_string_attribute can now retrieve
these fixed fields as well. #1063 (1.6.1)
* ImageInput & ImageOutput:
* New ImageOutput::supports() tags: supports("alpha") should be true
for image formats that support an alpha channel, supports("nchannels")
should be true for output formats that support an arbitrary number
of output channels. (1.6.2/1.5.13)
* ImageInput and ImageOutput supports() method has been changed to accept
a string_view (rather than a const std::string&), and return an int
(rather than a bool). (1.6.2)
* ImageInput and ImageOutput have added destroy() static
methods. They are just wrappers around 'delete', but can help you
to ensure that II and IO objects are deleted on the same side of a
DLL boundary as where they were created. (Helps with using OIIO
from DLL-based plugins on Windows.) (1.6.3)
* New ImageInput query: "procedural" -- returns 1 if the ImageInput may
not correspond to an actual file. #1154 (1.6.4/1.5.16)
* ImageInput and ImageOutput's error() method is changed from protected
to public, making it easier for an app to set an error on a reader
or writer. (1.6.4)
* ImageOutput::copy_to_image_buffer is a helper function that
generalizes the existing copy_tile_to_image_buffer, but for any
rectangle. #1193 (1.6.4)
* ImageInput::read_image() variant that takes a channel range to
read just a subset of the channels present. #1222 (1.6.5)
* ImageInput and ImageOutput now have new method threads(n) that sets
the thread "fan-out" for the ImageInput or ImageOutput individually,
overriding any global attribute("threads"). #1259 (1.6.6)
* ImageBuf:
* Add make_writeable(), which forces ImageCache-backed read-only
ImageBuf to read into locally allocated pixels so they can be
subsequently altered. #1087 (1.6.2)
* ImageBuf::Iterator has added set_deep_samples() and set_deep_value()
methods. (1.6.3)
* ImageBuf::set_pixels() now provides a way to set an arbitrary
rectancle of an ImageBuf from raw values. #1167 (1.6.4)
* ImageBuf::get_pixels() now has a variety that takes an ROI to
describe the rectangle of pixels being requested. #1167 (1.6.4)
* ImageBuf now has new method threads(n) that sets the thread
"fan-out" for the ImageInput or ImageOutput individually,
overriding any global attribute("threads"). #1259 (1.6.6)
* ImageCache/TextureSystem:
* Clarified in the docs that TextureSystem::get_texture_info and
ImageCache::get_image_info "exists" queries should return true, and
place in *data the value 1 or 0 depending on whether the image exists
and can be read. (1.6.0/1.5.10)
* Added handle-based versions of TextureSystem get_texture_info(),
get_imagespec(), imagespec(), and get_texels(), in addition to the
existing name-based versions of those methods. Note that
texture(), environment(), and texture3d() already had both
name-based and handle-based varieties. #1057 (1.6.1) #1083 (1.6.2)
* Add create_thread_info() and destroy_thread_info() methods that
allow an app to manage the per-thread records needed by the IC.
#1080 (1.6.2)
* Added ImageCache get_perthread_info() and get_image_handle() to
return opaque perthread and file handle pointers, much like
TextureSystem already had, and added handle-based versions of
get_image_info(), get_imagespec(), imagespec(), get_pixels(), and
get_tile(), in addition to the existing name-based versions of
those methods. #1057 (1.6.1)
* ImageCache get_tile and get_pixels have new varieties that let you
request channel begin/end range. This allows you to control which
channel ranges are in the cache, and thus be much more efficient
with cache storage when only a few channels are needed from a file
with many channels. #1226 (1.6.5)
* ImageBufAlgo:
* New ImageBufAlgo functions: abs, absdiff, div, fill, noise, mad,
invert, deepen, ociofiletransform.
* nchannels() now takes an 'nthreads' parameters, just like all the
other ImageBufAlgo functions. #1261 (1.6.6)
* Python bindings:
* Added previously-M.I.A. ImageSpec::erase_attribute(). #1063 (1.6.1)
* ImageSpec.set_channel_formats() now works when the channel
type lists are either TypeDesc, in addition to the existing support
for BASETYPE. #1113 (1.6.3/1.5.13)
* Added Python bindings for DeepData and deep reads (ImageInput) and
writes (ImageOutput), as well as additional DeepData and ImageBuf
methods to fully match the C++ API. #1113 #1122 (1.6.3/1.5.13)
* ImageBuf.set_pixels, and ImageBuf.get_pixels with ROI. #1167,1179 (1.6.4)
* Change Python ImageOutput bindings to simplify the write_* methods.
They no longer take both a TypeDesc and an array; it can figure out
the type from the array itself. Also get rid of the stride parameters,
which weren't useful in a Python context. #1184 (1.6.4)
* ImageBufAlgo colorconvert, ociolook, and ociodisplay now take an
optional string colorconfig argument. #1187 (1.6.4)
* Fix missing Python bindings for global OIIO::getattribute(). #1290
(1.6.8)
* The ColorConfig wrapper for OCIO functionality has been extended to
parse color names from filename strings, and to report the recommended
pixel data type for a color space. #1129 (1.6.3)
* C++11 definitions: oiioversion.h defines OIIO_BUILD_CPP11 as nonzero
if OIIO itself was built in C++11 (or later) mode, and platform.h
defines OIIO_USING_CPP11 as nonzero if at this moment C++11 (or
later) mode is detected. Note that these can differ if one set of
compiler flags was used to build OIIO, and a different set is used to
build a project that uses OIIO headers. #1148 (1.6.4)
* Renamed the "fps" standard metadata to "FramesPerSecond. #1193 (1.6.4)
* Removed deprecated header "string_ref.h" (use string_view.h). (1.6.1)
* oiioversion.h: Renamed the namespace macros OIIO_NAMESPACE_ENTER/EXIT to
OIIO_NAMESPACE_BEGIN/END, and roll the braces into it. #1196 (1.6.4)
* array_view.h: Refactor array_view to be more in line with what is slated
for C++17, in particular it is now templated on Rank and so can be a view
to a multi-dimensional array. Also change array_view_strided to have
strides measured in units of sizeof(T), not bytes (to keep with C++17).
This also adds coordinate.h to give definitions for the offset<>,
bounds<>, and bounds_iterator<> templates used by array_view. #1205
(1.6.4)
* Add top-level OIIO::get_int_attribute(), get_float_attribute(), and
get_string_attribute() helpers, similar to how they work in many
of the classes. #1283 (1.6.7)
Fixes, minor enhancements, and performance improvements:
* oiiotool
* Bug fix for frame sequences -- could crash in Windows. #1060 (1.6.1)
* Gracefully handle requests to save an image with more channels than
the output file format can handle. Instead of being a fatal error,
now it's just a warning, and extra channels are dropped. It tries to
to find R, G, B, and A channels, saving them. If those names are
not found, it just saves the first 3 (or 4) channels. #1058 (1.6.1)
* Improve error messages when files can't be read. It is now easier
to to distinguish files that don't exist from those that are an
unknown format from those that are corrupted or have read
errors. #1065 (1.6.1)
* Flag errors properly when -d specifies an unknown data format name.
#1077 (1.6.2/1.5.13)
* oiiotool numeric wildcard improvement: allow more digits to match.
#1082 (1.6.2/1.5.13)
* Bug fix: input file data format didn't always end up in the output.
(1.6.3)
* --channels bugs were fixed when dealing with "deep" images. (1.6.3)
* All the color space conversion operations run much faster now,
since the underlying IBA::colorconvert() has been parallelized. (1.6.3)
* --crop logic bug fixed in cases where the crop region was the same
size as the original pixel data window. #1128 (1.6.3)
* oiiotool now gives proper error messages when asked to perform
unsupported operations on deep images. (1.6.3)
* Bug fix: --frames incorrectly overrode explicit frame sequence
wildcards on the command line. #1133 (1.6.3)
* --crop, --trim, and --autotrim have been extended to work on
"deep" images. #1137 (1.6.3)
* For "procedural" ImageInputs, don't give "file doesn't exist"
errors. (1.6.4)
* Suppress output/copying of "textureformat" metadata inherited from
input if it's not plausibly still a valid texture (i.e., if it's
no longer tiled or MIPmapped). #1206 (1.6.4)
* oiiotool's full help message lists all supported formats. #1210 (1.6.5)
* oiiotool --help prints a briefer help screen. Use --help -v for
the full-detail help. #1214 (1.6.5)
* Bug fix in --fit when the image didn't need to be resized.
#1227 (1.6.5/1.5.21)
* Bug fix in --ch for "deep" files when the channel reordering is
the same as it already was. #1286 (1.6.7)
* ImageBufAlgo:
* compare() (and therefore oiiotool -diff and idiff) did not notice
image differences when the pixels that differed had NaN or NaN or
Inf values! Now it is right. #1109 (1.6.3/1.5.13)
* channels() bugs were fixed when dealing with "deep" images. (1.6.3)
* colorconvert() has been parallelized, and thus on most systems will
now run much faster. (1.6.3)
* render_text() handles UTF-8 input. #1121 (1.6.3)
* colorconvert(), ociodisplay(), and ociolook() have new varities that
accept an optional ColorConfig, rather than having no choice but to
construct a new one internally. (1.6.3)
* nonempty_region() and crop() have been extended to handle "deep"
images. #1137 (1.6.3)
* Fix bug in fft() -- was not always zeroing out the imaginary channel.
#1171 (1.6.4/1.5.17)
* Fixed uninitialized variable bugs with rangecompress() and
rangeexpand() when using luma. #1180 (1.6.4)
* The lanczos3, radial-lanczos, and catrom filters have been change
from fixed-width to fully scalable. This fixes artifacts that
occur when using them as upsizing filters. #1228,#1232 (1.6.5/1.5.21)
* maketx, TextureSystem, and ImageCache:
* TextureSystem/IC now directly stores uint16 and half pixel data in
the cache rather than converting internally to float for tile storage,
thus effectively doubling the cache capacity for files of those
formats. (1.6.3)
* Fix broken bicubic texture sampling with non-power-of-two sized
tiles. #1035 (1.6.0/1.5.10)
* maketx: when the source image was a crop (data window != display
window), and the sharpening filters were used, it would
incorrectly issue an "unknown filter name" error. #1059 (1.6.1/1.5.12)
* maketx: Flag errors properly when -d specifies an unknown data
format name. #1077 (1.5.13)
* maketx now writes to a temporary file, then moving it to the final
requested output filename only when the write completed without
error. This prevents situations where maketx crashes or is killed
and leaves behind a file that looks correct but is actually
corrupted or truncated. #1072 (1.6.2/1.5.13)
* TextureSystem bug fix that occasionally resulted in NaN in the
alpha channel result when looking up from 3-channel images. #1108
(1.6.3/1.5.13)
* maketx --runstats prints runtime staticstics (deprecating --stats).
#1152 (1.6.4)
* Fixed trilinear MIPmap texture lookups that gave invalid alpha fill.
#1163 (1.6.4/1.5.16)
* The lanczos3, radial-lanczos, and catrom filters have been change
from fixed-width to fully scalable. This fixes artifacts that
occur when using them as upsizing filters. #1228,#1232 (1.6.5)
* Texture cache memory efficiency is much better for the special case
of accessing just a few channels from a texture file with large
numbers of channels. #1226 (1.6.5)
* Eliminate spurious ImageCache invalidation just because the shared
cache is requested again. #1157 (1.6.4/1.5.16)
* Statistics output also shows all the option setting values. #1226 (1.6.5)
* Data copy error in ImageCache::get_pixels for partial-channel-set
copies. #1246 (1.6.5)
* maketx -u now remakes the file if command line arguments or OIIO
version changes, even if the files' dates appear to match.
#1281 (1.6.8)
* GIF:
* Write support! #1193 (1.6.4)
* On input, renamed "fps" metadata to "FramesPerSecond". #1193 (1.6.4)
* IFF:
* Fix botched output of 16 bit uncompressed data. #1234 (1.6.5/1.5.21)
* Make "rle" compression the default. #1234 (1.6.5/1.5.21)
* JPEG:
* Now properly read/write xdensity and ydensity (what OIIO and TIFF
call "XResolution" and "YResolution" and, therefore,
"PixelAspectRatio". #1042 #1066 (1.6.0, 1.6.1)
* Support JPEG files encoded as CMYK (by converting to RGB upon read)
#1044 (1.6.1)
* Fix misdeclared supports() which would make the JPEG plugin appear
to not support exif or iptc. #1192 (1.6.4)
* JPEG-2000:
* Fix handling of un-premultiplied alpha (which is dictated by the
JPEG-2000 spec). (1.6.3)
* Fix reading of YUV-encoded files. (1.6.3)
* Read and write the ICC profile, if present. (1.6.3)
* Handle all bit depth precisions properly (previously only 8, 10,
12, and 16 were right). (1.6.3)
* Set the full/display window correctly. (1.6.3)
* Deal with differing per-channel data windows and sampling rates. (1.6.3)
* OpenEXR:
* Improved handling of density and aspect ratio. #1042 (1.6.0)
* Fix read_deep_tiles() error when not starting at the image origin.
#1040 (1.6.0/1.5.10)
* Fix output of multi-part exr file when some parts are tiled and
others aren't. #1040 (1.6.0/1.5.10)
* write_tile() with AutoStride calculated the wrong default strides
for "edge" tiles when the image width or length was not an integer
multiple of the tile size. Also clarified the PDF and imageio.h
docs in how they explain strides for this case. #1055 (1.6.1/1.5.12)
* Fix bugs in reading deep OpenEXR images with mixed channel types.
#1113 (1.6.3/1.5.13)
* OpenEXR output supports("deepdata") now correctly returns 'true'.
#1238 (1.6.5/1.5.21)
* A separate global OIIO::attribute("exr_threads") sets the thread pool
size for OpenEXR's libIlmImf, independent of the OIIO thread fan-out
attribute OIIO::attribute("threads"). #1244 (1.6.5)
* Correctly read and write Matrix33 and double (scalar, 2d, 3d, m33, m44)
metadata. #1265,#1267 (1.6.6)
* Recognize AR/AG/AB channel names in addition to the old RA/RG/RB
#1277 (1.6.6)
* PNG:
* Writing PNG files now honors the PixelAspectRatio metadata.
#1142 (1.6.3)
* PFM:
* PFM (float extension of PNM) was incorrectly flipped top to bottom.
Now fixed. #1230 (1.6.5)
* PSD:
* Better error handling for files lacking "global layer mask info"
or "additional layer info". #1147 (1.6.4/1.5.18)
* Additional PSD signatures for global additional layer info.
#1147 (1.6.4/1.5.18)
* Better error handling when dealing with an empty layer mask.
#1147 (1.6.4/1.5.18)
* TIFF:
* Improved handling of density and aspect ratio. #1042 (1.6.0)
* Improved proper handling of the interplay between "XResolution",
"YResolution", and "PixelAspectRatio". #1042 (1.6.0)
* TIFF output: recognize special "tiff:write_exif" metadata, which when
present and set to 0, will skip writing the Exif directory into the
TIFF file. This can be helpful when you expect the resulting TIFF
file to be read with very old versions of libtiff. #1185 (1.6.4/1.5.18)
* Correct read and write of JPEG-compressed TIFF. #1207 (1.6.4)
* Correct support for reading LAB, LOG, YCbCr, subsampled chroma.
#1207 (1.6.4)
* Make robust to strange TIFF files that have unexpected MIP
level-to-MIP level changes in planarconfig, photometric, palette,
extrasamples, etc. #1220,1221 (1.6.5/1.5.20)
* Support output of 2, 4, 10, and 12 bit unsigned ints into TIFF files.
#1216 (1.6.5)
* Make TIFF reading more robust to certain subimage-to-subimage
changes that were thought to be invariant. #1221 (1.6.5)
* CMYK is properly read and written. Upon read, CMYK is auto-converted
to RGB (and the "tiff:ColorSpace" metadata is set to "CMYK"). For
output, if "tiff:ColorSpace" metadata is set and nonzero, the RGB
passed in will be auto-converted to CMYK upon writing.
#1233 #1245 (1.6.5)
* Recognize Exif tags in the main directory, not only the special
Exif directory. #1250 (1.6.5)
* Fix bug in read_scanlines when reading TIFF files with UNassociated
alpha and unusual ystride values. #1278 (1.6.6)
* ImageBuf iterator constructors with 0-size ranges or ROIs have been
fixed to look like they are immediately done(). #1141 (1.6.3)
* Fix bug in internal convert_image() that could corrupt certain image
copying of non-contiguous data layouts. #1144 (1.6.3)
* Also search for OIIO plugins in [DY]LD_LIBRARY_PATH. #1153 (1.6.4/1.5.16)
* Nuke plugin: don't crash with NULL Knob* in TxReaderFormat::setMipLabels.
#1212 (1.6.5/1.5.20)
* idiff -q results in quiet mode -- output nothing for success, only
minimal errors to stderr for failure. #1231 (1.6.5)
Build/test system improvements:
* Python plugin is now build as a cmake "module" rather than "library",
which fixes some things on OSX. #1043 (1.6.0/1.5.10)
* Various build fixes for Windows. #1052 #1054 (1.6.1)
* New CMake build-time option to specify the default plugin search path.
#1056 (1.6.1/1.5.12)
* Fix build breaks for very old versions of Ilmbase (1.6 and earlier)
that lack a definition of V4f used by our simd.h. #1048 (1.6.1/1.5.11)
* Fix signed/unsigned warning on 32 bit platforms in jpeginput.cpp.
#1049 (1.6.1/1.5.11)
* New CMake build-time option to specify the default plugin search path.
#1056 (1.6.1/1.5.12)
* Fix gcc 5.0 compiler warning in PtexHalf.cpp. (1.6.1/1.5.12)
* Remove dependency of OpenSSL by default. #1086 (1.6.2/1.5.13)
* Fix warnings when compiling with C++11. (1.6.3/1.5.13)
* Dont link Python framework on OSX. #1099 (1.6.3/1.5.13)
* Changed the way testtex warps the image to give faux perspective to
test texture mapping. (1.6.3)
* Build-time USE_SIMD=... has been changed from accepting a single tag to
a comma-separated list of feature options. So you can, for example, do
make USE_SIMD=avx,f16c ... (1.6.3)
* make USE_NINJA=1 causes CMake to build Ninja build files instead of
Makefiles (they execute much faster, espectially for incremental builds).
#1158 (1.6.4)
* PSD & JPEG plugins fixes for Win32 compilation. #1150 (1.6.4/1.5.16)
* Fix Nuke plugin build files to not do anything if USE_NUKE=0.
#1156 (1.6.4/1.5.16)
* Builds now produce much less console output by default (use VERBOSE=1
to get all the details, most of which is only useful when debugging
broken builds). #1162 (1.6.4)
* Fix support for older ffmpeg version on Ubuntu 14.04. #1168 (1.6.4/1.5.17)
* Build-time fixes for Nocona CPUs that have SSE3 without SSSE3.
#1175 (1.6.4/1.5.17)
* ustring internals fixes for gcc 5.x changs to std::string ABI. #1176 (1.6.4)
* Fixes for clean build with clang 3.6. #1182,1183 (1.6.4)
* Fix signed/unsigned comparison error. #1186 (1.6.4)
* Top-level Makefile option USE_OPENCV=0 to turn off even searching for
OpenCV components. #1194 (1.6.4/1.5.18)
* If a system-installed (external) PTex implementation is found, use
it. Only use the "bundled" version if no other is found. Also add a
top-level USE_PTEX=0 that will skip PTex support, even if the library
is found. #1195,1197 (1.6.4)
* Fix compiler warnings about int vs size_t mismatches. 1199 (1.6.4)
* Improve C++11 and C++14 readiness. #1200
* Fix build break with certain new versions of libraw. #1204 (1.6.4/1.5.19)
* Fix build warnings for new Apple tools release that upgrades the standard
clang release. #1218 (1.6.5/1.5.20)
* When compiling in C++11 mode, std::unordered_map, mutex,
recursive_mutex, lock_guard, bind, ref, cref, thread, shared_ptr will
be used rather than boost equivalents, and our own thread_group and
intrusive_ptr are now used rather than the boost equivalents. We
believe that this completely removes all Boost headers and types from
the OIIO public APIs when in C++11 mode. (Though internals still use
Boost in some cases.) #1262 #1266 (1.6.6)
* We are now set up to use Travis-CI (https://travis-ci.org) for continuous
integration / automatic builds of all merges and pull requests.
#1268, #1269, #1273 (1.6.6)
* Don't install fonts if USE_FREETYPE is disabled. #1275 (1.6.6)
* Use ccache for builds when detected and safe (unless USE_CCACHE=0).
#1274,#1285 (1.6.7)
* Failed tests now print their non-matching text output to the console
when doing 'make test'. This makes it much easier to spot most errors.
#1284 (1.6.7)
Developer goodies / internals:
* Strutil additions: parse_until, parse_nested (1.6.1), repeat
(#1272/1.6.6/1.5.21).
* Give Strutil::parse_string an option to not strip surrounding quotes.
(1.6.4)
* Made TypeDesc::equivalent accept comparisons of arrays of unspecified
length with ones of definite length. #1072 (1.6.2/1.5.13)
* Add Filesystem::rename() utility. #1070 (1.6.2/1.5.13)
* New SIMD methods: insert<>, xyz0, vreduce_add, dot, dot3, vdot, vdot3,
AxBxCxDx, blend0not (1.6.2)
* array_view enhancements that let you initialize an `array_view<const float>`
from a const `std::vector<float>&`. #1084 (1.6.2/1.5.14)
* hash.h contains several new hashes in namespaces 'OIIO::xxhash' and
'OIIO::farmhash'. Also, Strutil::strhash now uses farmhash rather than
the Jenkins one-at-a-time hash, bringing big speed improvements
(including ustring creation). Beware that the strhash value returned
will be different than they were before. #1090 (1.6.3)
* fmath: safe_fast_pow improves the precision of its results for
special cases of pow(x,1) and pow(x,2). #1094 (1.6.3/1.5.13)
* Added TypeDesc::TypeHalf(). #1113 (1.6.3/1.5.13)
* thread.h: our atomic types have had their API adjusted somewhat to
more closely conform to C++11's std::atomic. (1.6.3)
* ustring's internals and underlying hash table have been overhauled,
yielding much higher performance, especially when many threads are
simultaneously creating ustrings. (1.6.3)
* ROI improvement: make intersection & union robust to uninitialized ROIs
as arguments. (1.6.3)
* osdep.h is deprecated. Use platform.h instead. (1.6.3)
* The DISPATCH_TYPES utility macros used internally by IBA have been
improved, and in particular the DISPATCH_COMMON_TYPES now handle ALL
types ("uncommon" ones are silently converted to float). (1.6.3)
* platform.h moves the endian functions into the OIIO namespace. (1.6.3)
* platform.h adds functions for runtime query of CPU capabilities. (1.6.3)
* simd.h: float4 and int4 can now construct and load from unsigned short*,
short*, unsigned char*, char*, and 'half'. (1.6.3)
* Strutil::utf8_to_unicode (1.6.3)
* Filesystem::current_path(). #1124 (1.6.3/1.5.21)
* Filesystem enumerate_file_sequence and scan_for_matching_filenames
have been modified to clear their result vectors rather than simply
assume they are empty. #1124 (1.6.3)
* oiiotool internals have been refactored to be class-oriented and move
a lot of boilerplate repeated in each op to be part of the base
class. #1127 (1.6.3)
* timer.h: Timer and ScopedTimer have changed slightly. This isn't used
in any public OIIO APIs, but may affect 3rd party programs that like
to use OIIO's timer.h for convenience. #1201 (1.6.4/1.5.19)
* dassert.h: added OIIO_STATIC_ASSERT macros for static
assertion. Doesn't affect existing OIIO apps since they are new
additions, but feel free to use them! #1202 (1.6.4/1.5.19)
* New unit test for imagecache. #1246 (1.6.5)
* Sysutil::hardware_concurrency() and physical_concurrency(). #1263
(1.6.6/1.5.21)
