Release 1.5.16 (11 Jun 2015) -- compared to 1.5.15)
---------------------------------------------------
* PNG writes now honor PixelAspectRatio attribute.
* Build fixes for Visual Studio 2010
* PSD & JPEG plugins fixes for Win32 compilation.
* Also search for OIIO plugins in [DY]LD_LIBRARY_PATH.
* Give Strutil::parse_string an option to not strip surrounding quotes.
* Fix Nuke plugin build files to not do anything if USE_NUKE=0
* New ImageInput query: "procedural" -- returns 1 if the ImageInput may
not correspond to an actual file.
* TypeDesc has a new constructor and fromstring of a string_view, in
addition to the old versions that took char*.
* Eliminate spurious ImageCache invalidation just because the shared
cache is requested again.
* Fixed trilinear MIPmap texture lookups that gave invalid alpha fill.
* Filesystem: sequence matching should clear results arrays upon start.
Release 1.5.15 (11 May 2015) -- compared to 1.5.14)
---------------------------------------------------
* Bug fix with IBA::channels() with deep data with UINT channels.
* Fix TypeDesc compatibility with OSL.
* Misc WIN32 / VS2010 fixes.
* Fix incorrect logic in convert_image with certain channel types and
strides.
Release 1.5.14 (14 April 2015) -- compared to 1.5.13)
----------------------------------------------
* Added Python bindings for DeepData and deep reads (ImageInput) and
writes (ImageOutput).
* Improve IBA::compare() (and therefore oiiotool -diff and idiff) when
the images being compared have NaN or Inf values.
* TextureSystem bug fix that occasionally resulted in NaN in the alpha
channel result when looking up from 3-channel images.
* Fix IBA::channels() bugs when dealing with "deep" images.
* Fix bugs in reading deep OpenEXR images with mixed channel types.
* fmath: safe_fast_pow improves the precision of its results for
special cases of pow(x,1) and pow(x,2).
* Fix warnings when compiling with C++11.
* Dont link Python framework on OSX.
* Added TypeDesc::TypeHalf().
* Python ImageSpec.set_channel_formats() now works when the channel
type lists are either TypeDesc, in addition to the existing support
for BASETYPE.
* Build correctly against older TIFF versions.
Release 1.5.13 (10 Mar 2015) -- compared to 1.5.12)
----------------------------------------------
* oiiotool: Bug fix for frame sequences -- could crash in Windows.
* 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.
* oiiotool: 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.
* Improved handling of "PixelAspectRatio" for JPEG, TIFF, and OpenEXR.
* oiiotool: 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.
* 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.
* Python: added previously-M.I.A. ImageSpec.erase_attribute().
* Add Filesystem::rename() utility.
* Made TypeDesc::equivalent accept comparisons of arrays of unspecified
length with ones of definite length.
* oiiotool & maketx have improved error message when unknown data format
names are requested with "-d".
* oiiotool numeric wildcard improvement: allow more digits to match.
* Remove dependency of OpenSSL by default.
Release 1.5.12 (11 Feb 2015) -- compared to 1.5.11)
----------------------------------------------
* Various build fixes for Windows.
* New CMake build-time option to specify the default plugin search path.
(1.5.12)
* OpenEXR: fixed 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. (1.5.12)
* 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. (1.5.12)
* Fix gcc 5.0 compiler warning in PtexHalf.cpp. (1.5.12)
Release 1.5.11 (28 Jan 2015) -- compared to 1.5.10)
----------------------------------------------
* Fix build breaks for very old versions of Ilmbase (1.6 and earlier)
that lack a definition of V4f used by our simd.h.
* Fix signed/unsigned warning on 32 bit platforms in jpeginput.cpp.
Release 1.5 (26 Jan 2015) -- compared to 1.4.x
----------------------------------------------
Major new features and improvements:
* New oiiotool functionality/commands:
* --rotate90, --rotate180, --rotate270 rotate the image in 90 degree
axially-aligned increments with no filtering. (1.5.2)
* --reorient will perform whatever series of rotations or flips are
necessary to move the pixels to match the "Orientation" metadata that
describes the desired display orientation. (1.5.2)
* --autoorient will automatically do the equivalent of --reorient on
every image as it is read in, if it has a nonstandard orientation.
(This is generally a good idea to use if you are using oiiotool to
combine images that may have different orientations.) (1.5.2)
* --rotate rotates an image by arbitrary angle and center point,
with high-quality filtering. (1.5.3)
* --warp transforms an image using a 3x3 matrix, with high-quality
filtering. (1.5.3)
* --median performs a median filter. (1.5.4)
* New ImageBufAlgo functions:
* rotate90(), rotate180(), rotate270() rotate the image in 90 degree
axially-aligned increments with no filtering. (1.5.2)
* reorient() will perform whatever series of rotations or flips are
necessary to move the pixels to match the "Orientation" metadata that
describes the desired display orientation. (1.5.2)
* rotate() performs rotation with arbitrary angle and center point,
with high-quality filtering. (1.5.3)
* warp() transforms an image by a 3x3 matrix, with high-quality
filtering. (1.5.3)
* median_filter performs a median filter. (1.5.4)
* Significant internal speedups by utilizing SIMD instructions (SSE) in
the TextureSystem (1.5.5 , 1.5.6 ). To use this to its
fullest extent, build OIIO with the make/cmake option USE_SIMD=arch,
where arch is sse2, ssse3, sse4.1, sse4.2, depending on what machines
you'll be deploying to. (Note that x86_64 automatically implies at
least sse2.) We're finding that this has approximately doubled the
speed of the math part of texture mapping (it doesn't speed up the disk
I/O, of course). (1.5.5)
* Basic support for many movie files via a plugin using 'ffmpeg'. Works
with avi, mov, qt, mp4, m4a, 3gp, 3g2, mj2, m4v, mpg, and more. Movie
files simply look like multi-image files to OIIO. There isn't really
support for audio yet, and although this lets you retrieve and process
individual frames of a movie file, OIIO is still not meant to be a
video-processing library. Currently, these formats can be read, but
there is no write support (maybe coming soon). (1.5.5)
* Nuke plugins -- a txReader plugins that will read OIIO texture files,
and a txWriter that will output proper (tiled & mip-mapped) texture files
from Nuke. Contributed by Nathan Rusch / Luma Pictures. (1.5.6)

* CPack improvements. (#863)
* Fixes to docs-building makefiles. (#873)
* Make ImageSpec::get_float_attribute correctly convert many integer types.
(#862)
* Fixed some alloca calls that did not get the right amount of memory. (#866)
* OpenEXR: Improve the quality of lossy b44 compression by more correctly

perceptually linear). (#867)
* More robust build when OpenEXR and IlmBase have installed their
respective header files in different directories rather than the
expected behavior of being installed together. (#861)

#857, #858, #859
Release 1.4 (19 May 2014) -- compared to 1.3.x
----------------------------------------------
Major new features and improvements:
* The PNM reader now supports "PFM" files, which are the floating point
extension to PNM. (1.4.1)
* Preliminary support for reading a wide variety of digital camera "RAW"
files. (1.4.1)
* New oiiotool commands:
--cpow : raise pixel values to a power (1.4.1)
--label : give a name to the top-of-stack image, can be referred
to later in the command line (1.4.1)
--cut : combine --crop, --origin +0+0, and --fullpixels. (1.4.3)
--pdiff : perceptual diff (#815) (1.4.4)
--polar, --unpolar : complex <-> polar conversion. (#831) (1.4.5)
* oiiotool --resize and --fit, and also maketx when using "good" filters
for downsizing, have been significantly sped up. When downsizing
with large filters, we have seen up to 3x improvement. (#808) (1.4.3)
Public API changes:
* New ImageBufAlgo functions:
- pow() raises pixel values to a power. (1.4.1)
- cut() cuts a region of pixels and moves it to the origin (combines
crop, reset origin, and set full res = data resolution). (1.4.3)
- complex_to_polar() and polar_to_complex() convert from (real,imag)
to (amplitude,phase) and back. (#831) (1.4.5)
* New string_view class (in string_view.h) describes a non-owning
reference to a string. The string_view is now used in many places
throughout OIIO's APIs that used to pass parameters or return values
as char* or std::string&. Read string_view.h for an explanation of why
this is good. (1.4.2, 1.4.3) (N.B. this was called string_ref until 1.4.6,
when it was renamed string_view to conform to C++17 draft nomenclature.)
* New array_view<>, array_view_strided<>, strided_ptr<>, and image_view<>
templates are great utility for passing bounded and strided arrays. (1.4.3)
* Removed deprecated PT_* definitions from typedesc.h.
* Removed the quantization-related fields from ImageSpec. (1.4.3)
* Dither: If ImageOutput::open() is passed an ImageSpec containing the
attribute "oiio:dither" and it is nonzero, then any write_*() calls
that convert a floating point buffer to UINT8 output in the file will
have a hashed dither added to the pixel values prior to quantization
in order to prevent the appearance of visible banding. The specific
nonzero value passed for the attribute will serve as a hash seed so
that the pattern is repeatable (or not). (1.4.3)
Fixes, minor enhancements, and performance improvements:
* Improved oiiotool features:
* --stats on deep files now prints additional info, such as the minimum
and maximum depth and on which pixels they were encountered, as well
as which pixel had the maximum number of depth samples. (1.4.1)
* --resize and --resample allow WIDTHx0 or 0xHEIGHT, where the '0'
value will be interpreted as automatically computing the missing
dimension to preserve the aspect ratio of the source image.
(#797, #807) (1.4.3)
* Fixed possible crash when using --origin with tiled, cached
images. (1.3.12/1.4.2)
* --pdiff does a perceptual diff (like 'idiff -p'). (#815) (1.4.4)
* --dumpdata takes a noptional modifier empty=0 that will cause empty
deep pixels to not produce any output. (#821) (1.4.5)
* --polar, --unpolar convert from complex (real,imag) to polar
(amplitude, phase) and vice versa. (#831) (1.4.5)
* View wildcards: similar to frame range wildcards, "%V" is replaced by
new names, "%v" by the first letter of each view. The view list is
{"left","right"} by default, but may be set with the --views argument.
(1.4.5)
* --over and --zover set the resulting display/full window to the union
of those of the inputs; previously it set the display window to that
of the foreground image, which is often a poor default. (1.4.7)
* ImageCache/TextureSystem:
- The multi-point version of environment() was broken. (1.3.9/1.4.1)
- Don't honor the SHA-1 fingerprint found in a file if the "Software"
metadata doesn't indicate that the file was written by maketx or
oiiotool. (1.4.3)
* OpenEXR:
- Multi-part EXR (2.0) didn't write the required "name" attribute for
each part. (1.3.10/1.4.1)
- Fix crashing bug when reading stringvector attributes in the
file. (1.3.11/1.4.2)
- Add .sxr and .mxr as possible filename extensions (1.3.12/1.4.2)
- Smarter channel ordering of input of files with ZBack, RA, GA, or BA
channels (#822) (1.4.5).
- Adhere to the misunderstood limitation that OpenEXR library doesn't
allow random writes to scanline files. (1.4.6)
- More robust with certain malformed metadata. (#841) (1.4.6)
* TIFF: Give a more explicit error message for unsupported tile sizes (1.4.4)
* GIF: Fixes to subimage generation; GIF frames are treated as sequential
windows to be drawn on canvas rather than as independent images; respect
"disposal" method; initial canvas is now transparent and all GIFs are
presented as 4-channel images. (#828) (1.4.5)
* iconvert: properly handle multi-image files for formats that can't
append subimages. (1.3.10/1.4.1)
* iv info window should print native file info, not translated
ImageBuf/ImageCache info. (1.3.10/1.4.1)
* Fix ImageCache::get_pixels() for the chbegin != 0 case, when cache
and output buffer types were not identical. (1.3.10/1.4.1)
* DPX:
- Fixed several places in the where it could have had buffer
overruns when processing certain malformed string fields. (1.4.1)
- Fixed inappropriate use of "dpx_ImageDescriptor" could make invalid
DPX files (especially when reading metadata from one DPX file,
changing the number of channels, then writing out again as a DPX
file). (1.3.10/1.4.1)
- For output, honor the "Software" metadata attribute passed in.
(1.3.11/1.4.2)
- Ignore negative image origin values, which are not allowed by the
DPX spec which states they are unsigned. (#813) (1.4.4)
- Fix improper handling of unsupported pixel data types. (#818) (1.4.5)
- Accept pixel ratio (x/0) to mean 1.0, not NaN. (#834) (1.4.5/1.3.13)
- Pad subimages to 8k boundaries, as suggested by the DPX spec (1.4.7)
- Properly write "userdata" field to DPX files if set. (1.4.7)
* PNG:
- add "png:compressionlevel" and "compression" strategy attributes.
(1.3.12/1.4.2)
- output properly responds to "oiio:UnassociatedAlpha"=1 to indicate
that the buffer is unassociated (not premultiplied) and therefore it
should not automatically unpremultiply it. (1.4.5)
* Make ImageBuf iterators return valid black pixel data for missing
tiles. (1.3.12/1.4.2)
* Make the ImageOutput implementations for all non-tiled file formats
emulate tiles by accepting write_tile() calls and buffering the image
until the close() call, at which point the scanlines will be output.
(1.4.3)
* All ImageBufAlgo functions, and oiiotool, strip any "oiio:SHA-1" hash
values in the metadata in order not to confuse the TextureSystem. (1.4.3)
* IFF: accept write_scanline, even though IFF is tile only. (1.4.3)
* The implementation of the Lanczos filter (and any operations using it)
have been sped up by using an approximate fast_sinpi instead of the
more expensive sin() (1.4.3).
* Speed up iinfo --hash / oiiotool --hash by about 20%. (#809) (1.4.4)
* All format writer plugins: ensure that calling close() twice is safe.
(#810) (1.4.4)
* oiiotool --info and iinfo output have been altered slightly to make them
match and be consistent. Also, oiiotool didn't say that deep files were
deep (1.4.4).
* Fixed bad bugs in IBA::flatten() and oiiotool --flatten. (#819) (1.4.5)
* Fix Parameter neglect of properly copying the m_interp field for assignment
and copy construction. (#829) (1.4.5/1.3.13)
* Fix ImageBufAlgo::circular_shift (and oiiotool --cshift) that did not
wrap correctly for negative shifts. (#832) (1.4.5/1.3.13)
* The "gaussian" flter incorrectly had default width 2 (correct = 3),
and the "mitchell" filter incorrect had default width 3 (correct = 4).
These were bugs/typos, the new way is correct. If you were using those
filters in ways that used the default width value, appearance may change
slightly. (1.4.6)
Build/test system improvements:
* libOpenImageIO_Util is now built that only has the utility functions
in libutil (in addition to the libOpenImageIO, which contains everything).
This is handy for apps that want to use OIIO's utility functions (such
as ustring or Filesystem) but doesn't really need any of the image
stuff. A build flag BUILD_OIIOUTIL_ONLY=1 will cause only the util
library to be built. (1.4.1)
* New build option OIIO_THREAD_ALLOW_DCLP=0 will turn off an
optimization in thread.h, resulting in possibly worse spin lock
performance during heavy thread contention, but will no longer get
false positive errors from Thread Sanitizer. The default is the old
way, with full optimization! (1.4.1)
* More robust detection of OpenEXR library filenames. (1.4.1)
* Always reference OpenEXR and Imath headers as <OpenEXR/foo.h> rather
than <foo.h>. (1.4.1)
* Unit test strutil_test now comprehensively tests Strutil. (1.4.1)
* Fix broken build when EMBEDPLUGINS=0. (1.4.3/1.3.13)
* Fix broken build against OpenEXR 1.x. (1.4.3/1.3.13)
* version.h has been renamed oiioversion.h. For back compatibility, there
is still a version.h, but it merely includes oiioversion.h. (#811) (1.4.4)
* Moved all the public header files from src/include to
src/include/OpenImageIO, so that the src/include area more closely
matches the layout of an OIIO install area. (#817) (1.4.4)
* Fix compilation problems for PowerPC (#825). (1.4.5/1.3.13)
* Fixes for OpenBSD compilation. (#826/#830) (1.4.5/1.3.13)
* Fixes for Linux compilation when building with BUILDSTATIC=1. (1.4.6)
* Fixes for compilation against IlmBase/OpenEXR 2.1. (1.4.6)
* Improve finding of Freetype on some systems (1.4.6).
* Add to top level Makefile the option STOP_ON_WARNING=0 to let it cleanly
compile code that generates compiler warnings, without stopping the build.
(1.4.7)
Developer goodies / internals:
* TBB has been removed completely. (1.4.2)
* Slightly faster timer queries in timer.h for OSX and Windows. (1.4.1)
* Strutil :
- safe_strcpy() -- like strncpy, but copies the terminating 0 char. (1.4.1)
- split() fixes bug when maxsplit is not the default value. (1.3.10/1.4.1)
* ParamValue/ParamValueList :
- ParamValue now allows get/set of the internal 'interp' field. (1.3.9/1.4.1)
- ParamValueList::push_back is not properly const-ified. (1.4.1)
- New PVL::find() lets you search on the PVL. (1.4.6)
* fmath.h :
- New fast_sin, fast_cos, fast_sinpi, fast_cospi are much faster
polynomial approximations (with max absolute error of ~0.001). (1.4.3)
- round_to_multiple_of_pow2 - a faster version of the existing
round_to_multiple(), but only works when the multiple is known to be
a power of 2. (1.4.6)
* TypeDesc now has operator<, which makes it easier to use STL data structures
and algorithms that expect an ordering, using TypeDesc as a key. (1.4.6)
* thread.h
- Slight thread.h portability tweaks. (1.4.1)
- spin_rw_lock now has more standard lock()/unlock() as synonym for
for exclusive/write lock, and lock_shared()/unlock_shared() as
synonym for "read" locks. (1.4.6)
* ustring :
- new ustringLess and ustringHashIsLess functors make it easier to use
ustring as keys in STL data structures and algorithms that require
an ordering function. (1.4.6)
- improve thread performance significantly by using an
unordered_map_concurrent internally for the ustring table. (1.4.6)
* unordered_map_concurrent.h :
- Allow umc template to specify a different underlying map for the
bins. (1.4.6)
- Add retrieve() method that's slightly faster than find() when you just
need a value, not an iterator. (1.4.6)
- Align bins to cache lines for improved thread performance. (1.4.6)
* ImageBuf iterators have a new rerange() method that resets the iteration
range, without changing images or constructing a new iterator. (1.4.6)
Release 1.3.14 (19 May 2014 -- compared to 1.3.13)
--------------------------------------------------
* OpenEXR output: More robust with certain malformed metadata. (#841) (1.4.6)
* Rename the string_ref class to string_view. (This is unused in OIIO, it
is for compatibility with OSL.)
* Build fixes on Linux when using BUILDSTATIC=1.
* Add round_to_multiple_of_pow2 to fmath.h
* Add STOP_ON_WARNING option to the top level Makeile wrapper.
* Add documentation on the Python binding for IBA::cut.
* oiiotool --over and --zover now set the output image's display window to
the union of the inputs' display window, rather than to the foreground.

attribute for each part.
* iconvert: properly handle multi-image files for formats that can't
append subimages.
* iv info window should print native file info, not translated
ImageBuf/ImageCache info.
* Improved strutil_test now much more comprehensively unit tests
Strutil.
* Strutil::split() fixes bug when maxsplit is not the default value.
* Fix ImageCache::get_pixels() for the chbegin != 0 case, when cache
and output buffer types were not identical.
* DPX bug fix -- inappropriate use of "dpx_ImageDescriptor" could make
invalid DPX files (especially when reading metadata from one DPX
file, changing the number of channels, then writing out again as a
DPX file).
Release 1.3 (2 Dec 2013 -- compared to 1.2.x)
----------------------------------------------
Major new features and improvements:
* Huge overhaul of the Python bindings: TypeDesc, ImageSpec (1.3.2),
ImageInput, ImageOutput (1.3.3), ROI, ImageBuf (1.3.4), ImageBufAlgo
(1.3.6). The Python bindings were pretty rusty, badly tested,
undocumented, and had not kept up with recent changes in the C++ APIs.
That's all fixed now, the Python APIs are finally first-class citizens
(including full functionality, unit tests, and docs), and we intend to
keep it that way.
* The ability for an application to supply custom ImageInput and associate
them with a file extension. Those II's can do anything, including
generate image data procedurally.
* GIF reader
Public API changes:
* Large overhaul of the Python bindings. See the (finally existing!) docs.
* ImageBufAlgo:
* New functions: nonzero_region(); ociodisplay(), resize() variety
that lets you specify the filter by name; 2-argument (non-in-place)
versions of add, sub, mul, rangecompress, rangeexpand, unpremult,
premult, clamp fixNonFinite; sub() varieties that take float or
float* operands.
* Removed several IBA functions that have been deprecated since 1.2.
* Deprecated the single-image in-place versions of add, sub, mul,
rangecompress, rangeexpand, unpremult, premult, clamp fixNonFinite.
* ImageBuf:
* read() and init_spec() are no longer required, somewhat simplifying
application code that uses ImageBuf. All ImageBuf API calls
automatically read the spec and/or pixels from their named file if
they are needed, if it has not already been done. (1.3.4)
* save() is deprecated, and new ImageBuf::write() is now preferred
(naming symmetry). (1.3.4)
* New set_write_format() and IB::set_write_tiles() allow override of
default choices for data format and tile size for subsequent calls
to ImageBuf::write(). (1.3.4)
* ImageCache / TextureSystem:
* ImageCache::add_file() lets you seed the ImageCache with a "virtual file"
that will read from a custom ImageInput. This lets you add "procedural
images" to the IC.
* ImageCache::add_tile() lets you add tiles to the ImageCache. The caller
can initialize those tiles with any pixel values it chooses.
* A new variety of IC/TS::destroy() takes a 'bool teardown' parameter
that, when true, does a complete teardown of the underlying ImageCache,
even if it's the "shared" one. (1.3.7)
* OIIO::declare_imageio_format() exposes a way to give OIIO a custom
ImageInput and/or ImageOutput (via factory functions) and associate them
with particular file extensions. This makes it especially easy for an
app to make a procedural image generator that looks to the entire rest
of OIIO like a regular image file. (1.3.2)
* TypeDesc::VECSEMANTICS now have additional enum tags for TIMECODE and
KEYCODE to indicate that the data represents an SMPTE timecode or
SMPTE keycode, respectively. (1.3.7)
Fixes, minor enhancements, and performance improvements:
* oiiotool improvements:
* --autotrim Shrinks pixel data window upon output to trim black
edges. (1.3.2)
* --siappend Appends subimages of top two images on the stack. (1.2.2)
* --datadump will print all pixel values of an image (debugging tool) (1.3.6)
* --flatten turns a "deep" image into a flat one by depth-compositing within
each pixel (1.3.6).
* --ociodisplay applies an OpenColorIO display transformation. (1.3.7)
* Fix memory leak when processing frame range. (1.2.1/1.3.2)
* --help now returns a success error code, not a failure. (1.2.1/1.3.2)
* Fix incorrect help message about --ociolook. (1.2.1/1.3.2)
* Fix typo in "oiio:Colorspace" attribute name that interfered
with correct color space conversion in --colorconvert. (1.2.1)
* Many fixes and improvements to XMP & IPTC metadata handling. (1.2.2)
* Multithread speed improvement when opening files by reducing how
much time ImageInput::create and/or ImageOutput::create hold a
global mutex.
* oiiotool --origin and --fullpixels, when operating on cropped or
overscanned image, could sometimes do the wrong thing. (1.2.2/1.3.3)
* oiiotool --colorconvert did not work properly when the color
transformation was detected to be a no-op. (1.2.2/1.3.3)
* oiiotool --fit did not handle padding or offsets properly. (1.2.2/1.3.3)
* Changed/improved the behavior of --rangecompress/--rangeexpand. (1.3.3)
* 'oiiotool --pattern checker' was incorrect when nonzero offsets were
used. (1.2.3/1.3.4)
* oiiotool --runstats prints the total time/memory on every iteration
when doing file sequence wildcard iteration. (1.3.4)
* Eliminated a particular situation that might hit an ASSERT. Instead,
bubble up a real error message. (1.3.4)
* oiiotool --resize and --resample fixed for overscan images (1.3.5)
* --ociolook applies OCIO looks. (1.3.6)
* Supports printf-style frame range wildcards ('%04d') in addition to the
'#' style, and scan for matching frames if no explicit framespec is
provided. (1.3.6)
* ImageBufAlgo improvements:
* colorconvert() did not work properly when the color transformation was
detected to be a no-op.
* colorconvert(): added a variety that specifies color spaces by name.
* New ociolook() function applies OCIO "looks." (1.3.6)
* checker() was incorrect when nonzero offsets were used.
* checker() now has default values of 0 for the 'offset' parameters
(and so may be omitted if you want 0 offsets). (1.3.4)
* unsharp_mask() bug when src and dst were different data formats.
(1.2.3/1.3.4)
* Better dealing with cases of IBA functions detecting and issuing
errors when inputs that must be initialized are not. (1.3.4)
* We changed the behavior of rangecompress/rangeexpand. We swear
the new way is better. (1.3.3)
* New nonzero_region() returns the shrink-wrapped nonzero pixel data window.
(1.3.2)
* resize() has a new variety that lets you specify the filter by name
(rather than allocating ans passing a Filter2D*).
* resize() and resample() fixed to more robustly handle overscan
images. (1.3.5)
* over()/zover() are no longer restricted to float images. (1.3.7)
* ImageBuf:
* ImageBuf::write() writes untiled images by default, fixing some
tricky issues when IB's start thinking they're tiled because of
interaction with the ImageCache (which makes everything look tiled).
* ImageBuf::file_format_name() never worked properly, now is fixed (1.3.4)
* Fixed bug that caused incorrect ImageBuf::copy_pixels() when the two
IB's had different data types. (1.3.4/1.2.3)
* Improved iterator's handling of how overscanned pixels interact
with wrap modes. (1.3.6)
* Fixed a bug with black wrap mode not working correctly. (1.3.7/1.2.4)
* ImageCache/TextureSystem:
* More careful with texture de-duplication -- texture value lookups
use de-duplication, but metadata lookups (e.g., get_texture_info)
uses the metadata from the original file.
* get_image_info/get_texture_info queries for "datawindow" and
"displaywindow". (1.3.6)
* The multi-point version of environment() was broken. (1.3.9)
* maketx: --hicomp uses the new range compression/expansion formula. (1.3.3)
* DPX:
* support multi-image (often used for stereo frames).
* Fixed DPX input that didn't recognized offset/cropped images.
(1.2.2/1.3.3, another fix in 1.3.4)
* Fixed DPX output crash with cropped images. (1.2.2/1.3.3)
* Now correctly get and set "smpte:TimeCode" and "smpte:KeyCode"
metadata. (1.3.7).
* OpenEXR:
* Fixed write_scanlines handling of per-channel data types (1.3.6)
* Several OpenEXR 2.0 deep file fixes: only some compression types
supported, write_tiles passed wrong parameters, must suppress some
attribute names. (1.2.3/1.3.6)
* Now correctly get and set "smpte:TimeCode" and "smpte:KeyCode"
metadata. (1.3.7).
* JPEG: fixed that some JPEG files were not being recognized because of
magic number issues.
* TGA: Correctly unassociate alpha if it's from an unasociated file;
also, always write unassociated data because so few Targa readers in
the wild seem to properly handle associated alpha.
* PNG: More correct handling of unassociated alpha.
* TIFF: More correct handling of unassociated alpha.
* PSD: fix handling of associated vs unassociated alpha. (1.2.3)
* maketx fixed to handle inputs that are a mixture of cropped and
overscanned. (1.3.5)
* Fix segfault if OCIO is set to a non-existant file. (1.3.6)
* Slight performance increase when writing images to disk (1.3.6)
* Many fixes to make OIIO compile with libc++ (clang's new C++ library,
and the default on OSX Mavericks). (1.2.3/1.3.6, 1.3.7)
* Fixed several potential buffer overflow errors from unsafe strcpy. (1.3.8)
Build/test system improvements:
* Fix broken tests under Windows. (1.3.2)
* Many fixes for compiler warnings on various platforms: fmath_test.cpp,
field3dinput.cpp, sysutil.cpp, argparse.cpp, oiiotool.cpp. (1.2.1/1.3.2)
* Fixes problems on little-endian architecture with texture3d.cpp.
(1.2.1/1.3.2)
* Fix compilation problems on architectures with gcc, but no 'pause'
instruction. (1.2.1/1.3.2)
* Fix build search path for correctly finding libopenjpeg 1.5. (1.2.1)
* Work around bug in older MSVC versions wherein Filesystem::open needed
to explicitly seek to the beginning of a file. (1.2.1/1.3.2)
* Build fixes for FreeBSD. (1.2.1/1.3.2, 1.2.4/1.3.6)
* Fix testsuite/oiiotool on Windows -- windows shell doesn't expand
wildcards. (1.2.1/1.3.2)
* Fix warnings for new GCC 4.8 compiler.
* Always search for and use the release HDF5 libraries, not the debugging
ones, even when building debug OIIO (this fixes errors when a system
does not have the debugging HDF5 libraries installed). (1.2.2/1.3.3)
* Extensive unit tests in the testsuite for the Python bindings.
* Fix compiler error on MIPS platform. (1.2.2/1.3.3)
* Add FIELD3D_HOME description to 'make help' (1.2.2/1.3.3)
* Add cmake variables ILMBASE_CUSTOM_INCLUDE_DIR, ILMBASE_CUSTOM_LIB_DIR,
OPENEXR_CUSTOM_INCLUDE_DIR, and OPENEXR_CUSTOM_LIB_DIR to make it
easier to have site-specific hints for these packages' locations. (1.3.4)
* Add BOOST_HOME and OCIO_HOME controls from the top-level Makefile wrapper.
(1.3.4/1.2.3)
* Accommodate new cmake release that slightly changes the HDF5 library
naming. (1.3.6)
* Various fixes to make the code compile properly with libc++ (clang's
rewrite of the C++ standard library). (1.3.6)
* Updated PugiXML (partly to help compilation with libc++) (1.3.6)
* Better support for NOTHREADS (for some legacy systems) (1.3.6)
* Fix to __attribute__(visibility) for gcc < 4.1.2 (1.3.6)
* Improve the CMake build files to fully quote path constructions to make
it more robust for builds with paths containing spaces. (1.3.7)
* Moved the main CMakeLists.txt file to the top level directory, per usual
CMake conventions. (1.3.7)
Developer goodies:
* Docs improvement: full documentation of ImageBufAlgo. (1.2.1/1.3.2)
* Merge improved "Tinyformat" that fixes a bug in some old glibc versions
(1.3.2).
* Now each command line tools explicitly converts to UTF native arguments,
rather than relying on it happening in ArgParse (which no longer does
so). (1.3.2)
* Strutil::contains() and icontains(). (1.2.2/1.3.3)
* Updatd "Tinyformat" to the latest release (1.3.6)
* Sysutil::physical_memory() tries to figure out the total physical memory
on the machine. (1.3.6)

* Many fixes to make OIIO compile with libc++ (clang's new C++ library,
and the default on OSX Mavericks).
* Fix OpenEXR write_scanlines handling of per-channel data types.
* Upgraded PugiXML to a more modern version (necessary for clean compile
with libc++).

Release 1.2 (8 July 2013)
-------------------------
Major new features and improvements:
* New oiiotool commands:
--swap Exchanges the top two items on the image stack.
--fit Resize image to fit into a given resolution (keeping aspect).
--ch Select/cull/reorder/add channels within an image.
--chappend Merge two images by appending their color channels.
--chnames Rename some or all of the color channels in an image.
--zover Depth compositing
--cadd Add constant per-channel values to all pixels
--cmul Multiply an imge by a scalar or per-channel constant.
--fillholes Smoothly interpolate for hole filling.
--resample Similar to --resize, but just uses closest pixel lookup.
--clamp Clamp pixel values
--rangeexpand Expand range for certain HDR processing
--rangecompress Compress range for certain HDR processing
--unpremult Divide colors by alpha (un-premultiply).
--premult Multiply colors by alpha.
--kernel Make a convolution kernel using a filter name.
--convolve Convolve two images.
--blur Blur an image.
--unsharp Sharpen an image using an unsharp mask.
--paste Paste one image on another.
--mosaic Create a rectilinear image mosaic.
--transpose Transpose an image (flip along the diagonal axis)
--chsum Sum all channels in each pixel
--cshift Circular shift an image pixels
--fft --ifft Forward and inverse Fourier transform
--colorcount Counts how many pixels are one of a list of colors.
--rangecheck Counts how many pixels fall outside the given range.
--ociolook Apply OpenColorIO "looks"
--autotrim Shrinks pixel data window upon output to trim black edges.
* oiiotool can loop over entire numeric frame ranges by specifying
wildcard filenames such as "foo.#.tif" or "bar.1-10#.exr".
* oiiotool --frames and --framepadding give more explicit control over
frame range wildcards.
* Significant performance improvements when reading and writing images
using the ImageBuf::read and ImageCache::get_pixels interfaces, and in
some cases also when using regular ImageInput. This also translates
to improved performance and memory use for oiiotool and maketx.
* At least doubled the performance of maketx for large images when run
on multi-core machines.
* Significant performance improvements when using ImageBuf::Iterator
or ConstIterator to traverse the pixels in an ImageBuf, and the iterators
now support "wrap" modes (black, clamp, periodic, mirror).
* maketx --hicomp does "highlight compensation" by compressing the
HDR value range prior to inter-MIP resizes, then re-expanding the range.
* Field3D writer (it could read f3d files before, but not write them).
* idiff can now compare that are not the same size (treating pixels
beyond the pixel data window is being 0 valued).
* maketx --lightprobe turns a "lightprobe" iamge into a latlong environment
map.
* Significant improvements and fixes to EXIF, IPTC, and XMP metadata
reading and writing.
* Significant thread scalability improvements to TextureSystem and
ImageCache.
* Huge overhaul of functionality, style, and performance of the
entire ImageBufAlgo set of functions (see the "Public API changes"
section below, and the imagebufalgo.h file for details).
Public API changes:
* ImageOutput semantics change: If the spec passed to open() has
spec.format set fo UNKNOWN, then select a default data format for the
output file that is "most likely to be able to be read" and/or "most
typical for files of that format in the wild." Also,
ImageOutput::open() will never fail because a requested data format is
unavailable; if the requested format is not supported, a reasonable
alternate will always be chosen.
* ImageBuf has been changed to a "PIMPL" idiom, wherein all the
internals are no longer exposed in the public API. This allows us to
change ImageBuf internals in the future without breaking API or link
compatibility (and thus giving us more freedom to backport important
improvements to prior releases).
* Overhaul of ImageBufAlgo functions: they all take an ROI parameter;
use the DISPATCH macros to make them work with all pixel data types
where practical (previously, many supported float only); use Iterator
rather than getpixel/setpixel, leading to huge speed improvements;
multithread when operating on enough pixels, leading to huge speed
improvements; work on 3D (volume) images where applicable; always
gracefully handle uninitialized dest image or undefined ROI.
* New ImageBufAlgo functions: channels(), channel_append(), mul(),
paste(), zover(), add() and mul() varieties that that add/multiply a
constant amount to all pixels, fillholes_pp(), resample(), clamp(),
rangecompress(), rangeexpand(), make_kernel(), unsharp_mask(),
transpose(), channel_sum(), circular_shift(), fft(), ifft(),
color_count(), color_range_check(), nonzero_region().
[look in imagebufalgo.h for documentation.]
* ImageBufAlgo::make_texture() allows you to do the same thing that
maketx does, but from inside an application and without launching a
shell invocation of maketx. Two varieties exist: one that takes a
filename and reads from disk, another that takes an ImageBuf already
in memory.
* ImageBuf Iterator/ConstIterator now take "wrap" mode parameters that
allow out-of-range iterators to be able to retrieve valid data. Supported
wrap modes include black, clamp, periodic, and mirror. This simplifies
a lot of algorithms using IB::Iterator, they can now be written to
rely on wrap behavior rather than being cluttered with checks for
"if (it.exits())" clauses.
* ImageBufAlgo::computePixelHashSHA1 has been refactored to take ROI,
a block size, and thread count, and thus can be parallelized with threads.
The block size means that rather than computing a single SHA-1 for all
the pixels, it computes separate (parallel) SHA-1 for each group of
blocksize scanlines, then returns the SHA-1 of all the individual SHA-1
hashed blocks. This is just as strong a hash as before, thought the value
is different than doing the whole thing at once, but by breaking it into
blocks the computation can be multithreaded.
* ImageBuf::swap() makes it easy to swap two ImageBuf's.
* ImageSpec::get_channelformats is now const (and always should have been).
Fixes, minor enhancements, and performance improvements:
* TextureSystem improvements:
* Make sure "black" wrap wins out over "fill" value when they conflict
(looking up an out-of-range channel beyond the pixel data window).
* "mirror" wrap mode was slightly incorrect and has been fixed.
* oiiotool improvements:
* oiiotool -v breaks down timing by individual function.
* oiiotool has been sped up by forcing read of the whole image up front
for reasonably-sized files (instead of relying on ImageCache).
* oiiotool does not write output images if fatal errors have occurred.
* oiiotool --diff: Better error handling, better error printing, and
now it can compare images with differing data windows or channel
numbers ("missing" channels or pixels are presumed to be 0 for the
purposes of comparing).
* oiiotool --resize (and --fit): properly handle the case of resizing
to the same size as the original image.
* oiiotool -d CHAN=TYPE can set the output for just one channel.
* ImageBufAlgo improvements:
* Internal overhaul of IBA::resize to greatly speed it up.
* Improve IBA::resize to handle the image edge better -- instead of
clamping, just don't consider nonexistant pixels.
* More careful selection of filter when resizing (IBA::resize, oiiotool
--resize and --fit, and maketx).
* Fix IBA::paste() error when the foreground image runs off the end of
the background image.
* Bug fix when computing SHA-1 hash of 0-sized images.
* Image format support improvements:
* Bug fix where some format readers (PNM, SGI, and IFF) would leave the
file handle opened if the ImageInput was destroyed without calling
close() first. Now we guarantee that destroying the II always causes
the file to close().
* DPX: output allocation bug fix; properly set pixel aspect ratio for
DPX write.
* IFF: bug fix for endian swap for IFF file input.
* JPEG2000: fix warnings, make sure event manager transfer object
remains valid.
* OpenEXR: when reading, was botching the ordering of per-channel data
formats.
* SGI write: bug fix for the case of 15 bpp RLE encoding, was
double-swapping bytes.
* Targa: more robust check for presence of alpha channels; bug fix where
R and B channels were reversed for certain kinds of palette images.
* TIFF: Store the orientation flag properly when outputting a TIFF file.
* maketx improvements:
* maketx --chnames allows you to rename the channels when you create a
texture.
* maketx bug fixes: incorrect weighting when resizing MIP levels for
latlong environment map images that could make visible artifacts
on some intermediate MIP levels.
* encode_exif() didn't copy the right number of bytes.
* Python bindings: ImageSpec extra_attribs now properly responds to
iterator calls.
* Fix bug in sRGB -> linear conversion.
* iv: make pixelview display coordinates & color even when outside the
data window.
Build/test system improvements:
* Many fixes to improve builds and eliminate warnings on Windows and MinGW.
* Fix missing InterlockedExchangeAdd64 for Windows XP.
* New make/cmake boags: OIIO_BUILD_TOOLS=0 will exclude building of the
command line tools (just build libraries), OIIO_BUILD_TESTS=0 will
exclude building of unit test binaries.
* Improved matching of testsuite reference images on different platforms.
* Lots of fixes to compiler warnings on newer gcc and clang releases.
* Unit tests for Timer class.
* libOpenImageio/imagespeed_test benchmarks various methods of reading
and writing files and iterating image pixels (to help us know what to
optimize).
* If OpenSSL is available at build time, OIIO will use its SHA-1
implementation instead of our own (theirs is faster). We still fall
back on ours if OpenSSL is not available or when OIIO is built with
USE_OPENSSL=0.
* Allow default the shared library suffix to be overridden with the
CMake variable OVERRIDE_SHARED_LIBRARY_SUFFIX.
* Eliminated all uses of the custom DEBUG symbol, and instead use the
more standard idiom "#ifndef NDEBUG".
* Compatibility fixes for Python3.
* MSVC 2008: Prevent a redefinition error when using boost::shared_ptr.
* Fixes for compatibility with libtiff 4.0.
* Fixes for MSVC debug mode having out-of-bound exceptions.
* Fixes for libjpeg 9.x.
* Compile to treat warnings as errors (you can disable this with
STOP_ON_WARNING=0).
* New filter: "sharp-gaussian".
* Fix various Windows build errors.
* Improvements to the build when finding IlmBase/OpenEXR.
* Various fixes to compile on ARM architecture.
* Fixes to compile on ESA/390 mainframe (!).
* testtex --threadtimes, --trials, --iters, --nodup, --wedge. These
are helpful in using testtext to benchmark the texture system.
* Improvements to make more tests work properly on Windows.
Developer goodies:
* Improved ASSERT and DASSERT macros to not generate warning for certain
debug compiles; key their debug behavior by the absence of the standard
NDEBUG idiom rather than presence of a custom DEBUG symbol; rename the
message variants ASSERT_MSG and DASSERT_MSG.
* Change the default for Sysutil::memory_used to report resident memory
rather than virtual process size.
* Multithread/parallel version of utility function convert_image().
* imagebufalgo.h improvements and expansion of the various DISPATCH_*
macros.
* New Filesystem utilities: parent_path(), get_directory_entries().
* New Strutil utilities: extract_from_list_string
* spinlock tweaks make it faster than TBB's spin locks!
* By default, we no longer build or use TBB (it's considered deprecated,
but in 1.2 can still be turned on with USE_TBB=1).
* In fmath.h, added definitions for safe_inversesqrt, safelog, safe_log2,
safe_log10, safe_logb.
* In typedesc.h, added TypeDesc::tostring() function.
* unordered_map_concurrent.h contains a template for a thread-safe
unordered_map that is very efficient even for large number of threads
simultaneously accessing it.
* Documentation: Finally, a chapter in the PDF docs that fully describes
the ImageBuf class.
Release 1.1.13 (24 Jun 2013)
----------------------------
* Texture: make sure wrap mode "black" wins over "fill" value when they
conflict.
Release 1.1.12 (20 Jun 2013)
----------------------------
* Fix oiiotool '#' wildcard, was broken on Windows.
* Fix an overflow problem that plagued 'maketx' when running on input
larger than 32k x 32k (among other possible failures).
Release 1.1.11 (29 May 2013)
----------------------------
* IFF input: bug in endian swap of 16 bit IFF files.
* oiiotool: fix a minor bug where tiled files were output inappropriately.
(Had been patched in master some time ago.)
* fmath.h additions: safe_inversesqrt, safe_log, safe_log2, safe_log10,
safe_logb. These are versions that clamp their inputs so that they
can't throw exceptions or return Inf or NaN.
* Fix to not incorrectly print ImageCache stats for certain broken files.
Release 1.1.10 (13 Apr 2013)
----------------------------
* IBA::fillholes() and oiiotool --fillholes can smoothly fill in alpha
holes with nearby colors. Great for extrapolating the empty areas of
texture atlas images so that filtered texture lookups pull in a plausible
color at part edges.
* IBA::clamp and oiiotool --clamp clamp pixel values to a scalar or
per-channel min and/or max, or clamp alpha to [0,1].
* IBA::rangecompress()/rangeexpand(), and oiiotool --rangecompress /
--rangeexpand compress the excess >1 values of HDR images to a log
scale (leaving the <= 1 part linear), and re-expand to the usual
linear scale. This is very helpful to reduce ringing artifacts that
can happen when an HDR image is resized with a good filter with negative
lobes (such as lanczos3), by doing a range compression, then the resize,
then range expansion. It's not mathematically correct and loses energy,
but it often makes a much more pleasing result.
* maketx --hicomp does highlight compression -- automatically doing a
range compress before each high-quality resize step, and then a
range expansion and clamp-to-zero (squash negative pixels) after
each resize.
* DPX - when writing DPX files, properly set the pixel aspect ratio.
Release 1.1.9 (2 Apr 2013)
--------------------------
* IBA::resize and oiiotool --resize/--fit: Bug fixes to resize filter
size selection fix artifacts wherein extreme zooms could end up with
black stripes in places where the filters fell entirely between samples.
* oiiotool --fit: fix subtle bugs with aspect ratio preservation for
images with differing data and display windows; and allow "filter=..."
to override the default filter used for fit.
* Resize improvement: fix potential artifacts at the image edges resulting
from odd clamping behavior.
* Even more frame range wildcard flexibility with oiiotool --frames and
--framepadding options.
* oiiotool --resize and --fit (and the underlying IBA::resize()) have been
sped up significantly and are now also multithreaded.
Release 1.1.8 (15 Mar 2013)
---------------------------
* oiiotool --chappend (and ImageBufAlgo::channel_append() underneath) allow
you to take two files and concatenate their color channels.
* oiiotool --chnames allows you to rename some or all of a file's color
channels.
* oiiotool can loop over entire frame ranges by specifying wildcard
filenames such as "foo.#.tif" or "bar.1-10#.exr".
* Cmake: OVERRIDE_SHARED_LIBRARY_SUFFIX allows the shared library suffix
to be overridden (e.g., if you need to force .so names on OSX rather
than the usual default of .dylib).

NetBSD 6, requested by tron.
|
|
Recursively bump package revisions again after the "freetype2" and
"fontconfig" handling was fixed.
|
|
to address issues with NetBSD-6(and earlier)'s fontconfig not being
new enough for pango.
While doing that, also bump freetype2 dependency to current pkgsrc
version.

Changelog:
Release 1.1.7 (21 Feb 2013)
---------------------------
* Back out dangerous change to thread.h that was in 1.1.6, which could
cause performance problems.
* Compile fix for WIN32 in strutil.cpp
* Compile fix for Windows XP - add implementation of InterlockedExchangeAdd64
Release 1.1.6 (11 Feb 2013)
---------------------------
* Fix bug that could generate NaNs or other bad values near the poles of
very blurry environment lookups specifically from OpenEXR latlong env maps.
* Fix bug in oiiotool --crop where it could mis-parse the geometric parameter.
* Fix bug in ImageCache::invalidate() where it did not properly delete the
fingerprint of an invalidated file.
* Cleanup and fixes in the oiiotool command line help messages.
* New function ImageBufAlgo::paste() copies a region from one IB to another.
* oiiotool --fit resizes an image to fit into a given resolution (keeping the
original aspect ratio and padding with black if needed).
* ImageBufAlgo::channels() and "oiiotool --ch" have been extended to allow
new channels (specified to be filled with numeric constants) to also be
named.
* New function ImageBufAlgo::mul() and "oiiotool --cmul" let you multiply
an image by a scalar constant (or per-channel constant).
* Important maketx bug fix: when creating latlong environment maps as
OpenEXR files, it was adding energy near the poles, making low-res
MIP levels too bright near the poles.
* Fix to "oiiotool --text" and "oiiotool --fill" -- both were
incorrectly making the base image black rather than drawing overtop of
the previous image.
* Fix FreeBSD compile when not using TBB.
* New oiiotool --swap exchanges the top two items on the image stack.

Changelog:
Release 1.1.5 (29 Jan 2013)
---------------------------
* Bug fix in ImageBufAlgo::parallel_image utility template -- care when
not enough work chunks to dole out to all the threads (was previously
sending work to threads with nonsensical ROI's, now we just stop when
all the regions have been doled out).
* Additional optional argument to IBA::zover that, when nonzero, will
treat z=0 pixels as infinitely far away, not super close. You can turn
this on from oiiotool with: oiiotool --zover:zeroisinf=1 ...
Release 1.1.4 (27 Jan 2013)
---------------------------
* ImageBufAlgo::make_texture() allows you to do the same thing that
maketx does, but from inside an application and without launching a
shell invocation of maketx.
* oiiotool now recognizes --metamatch and --nometamatch arguments which
cause metadata names matching (or only info NOT matching) the given
regular expression to be printed with --info.
* oiiotool --zover does z (depth) composites (it's like a regular "over",
but uses the z depth at each pixel to determine which of the two images
is the foreground and which is the background).
* ImageBufAlgo::zover() performs z compositing (same as oiiotool --zover).
* ImageBufAlgo::fixNonFinite didn't work properly with 'half' image buffers.
* Performance improvements when reading and writing images.
* Fix error when writing tiled 'float' TIFF images, corrupted output.
(Could easily happen when using 'maketx' to convert float images into
TIFF textures.)
* Eliminate warnings when compiling with Clang 3.2.
* New CMake variable "USE_EXTERNAL_TBB" can optionally be set to force use
of an external TBB library rather than the embedded one.
* Additional testsuite tests (doesn't affect users, but makes bugs easier
to catch).
* Fix build problem with SHA1.cpp on some platforms.
Release 1.1.3 (9 Jan 2013)
---------------------------
* Build fix: incorrectly named OpenEXR 2.x files.
* Bug fix in oiiotool --croptofull on OSX
* Build fixes for MinGW on Windows.
* maketx --fullpixels option ignores any origin or display window in the
source image, pretending the pixel data is the entire 0-1 image range
starting at the origin (useful when the source image is created by an
application that incorrectly writes it out as if it were a crop window).
* maketx no longer will clobber existing ImageDescription metadata
when it adds SHA-1 hash or other info as it creates the texture.
* Many additional Exif and IPTC tags are correctly recognized.
* maketx and oiiotool recognize and take advantage of IPTC:ImageHistory
metadata.

|
|
--------------------------
* maketx fixes -- was botching creation of textures from source images that
were crop windows (pixel window smaller than display window).
* Minor bug fix to Timer when repeatedly starting and restopping (Apple only).
* Bug fix in ustring:find_last_not_of

OpenImageIO is a library for reading and writing images, and a
bunch of related classes, utilities, and applications. There is
a particular emphasis on formats and functionality used in
professional, large-scale animation and visual effects work for
film. OpenImageIO is used extensively in animation and VFX studios
all over the world, and is also incorporated into several commercial
products.
