Special Issues:
Due to GCC bug 53967, several key agorithms (e.g. convolution) may execute much faster (e.g. 2-3X) for x86-64 and/or when SSE is enabled for floating point math (-mfpmath=sse) if the GCC option -frename-registers is used. Default 32-bit builds do not experience the problem since they use '387 math. It is not clear in what version of GCC this problem started but it was not noticed by the developers until the GCC 4.6 timeframe. Other compilers do not suffer from this bug. Please lobby the GCC project to fix this embarrassing performance bug.
Bug fixes:
Compilation: No longer undefine __attribute__ since this may be used by system or compiler headers and cause problems.
BMP: Alpha channel from BMP3 format was inverted.
PNG: Fix round-trip repeatability issue (due to rounding algorithm) with modern versions of libpng. Prefer the less accurate method which does not alter the image.
PNG: Fix some memory leaks in error-handling paths.
PNM: Scaling of alpha in sub-ranged pixels is fixed.
Wand API: Removed development debug fprintf which causes each drawing primitive to be printed to stderr.
PS, PS2, PS3, PDF: Only use resolution from image or -density if units was properly specified. Without units, resolution is worthless.
PS, PS2, PS3, PDF: Use resolution from image if it appears to be valid.
WebP: Fix inverted return status which caused failure to be reported instead of success.
Rotation clipping/shearing errors for short wide images at some angles is fixed.
-geometry: Deal with resize geometry missing width or height (e.g. '640x' or 'x480') by substituting the missing value with one which preserves the image aspect ratio. This has been documented to be supported since almost the dawn of GraphicsMagick but was not actually supported until now.
-geometry: Support '>' and '<' qualifiers with '@' qualifier to specify if image should be resized if larger or lesser than given area specification.
New Features:
Wand API: MagickSetImageGravity() - New function to set image gravity.
Wand API: MagickGetImageGravity() - New function to get image gravity.
Wand API: MagickSetImageMatte() - New function to set the image matte channel enable flag.
Wand API: MagickGetImageMatte() - New function to read the image matte channel enable flag.
Wand API: MagickSetImageGeometry() - New function to set the image geometry string.
Wand API: MagickGetImageGeometry() - New function to get the image geometry string.
Wand API: MagickOperatorImageChannel() - New function to apply an operator to an image channel.
Magick++ API: New Image::thumbnail() method for fast image resizing, particularly to make thumbnails.
Core C API: Added SetLogMethod() to allow an application/library to specify a function to be called for logging.
Clang/LLVM: Provide support for clang/llvm attribute and builtin specifiers similar to that provided for GCC.
OpenMP: OpenMP native locking and thread specific data is supported via a configuration option (is not the default). This offers a "pure" OpenMP compilation mode. No real value for this compilation mode has been observed yet but it seems worthy to support.
Coders: Added BrokenCoderClass to mark coders which often malfunction or are not very useful in their current condition.
Composition: Added HardLight composition operator, which is now used by PSD and XCF formats, and available via command line, Magick++ API, PerlMagick API, and Wand API.
Composition: Added ScreenCompositePixels composition operator.
Composition: Added missing Photoshop separable compositing operations, Overlay, Exclusion, ColorBurn, ColorDodge, SoftLight, LinearBurn, LinearDodge, LinearLight, VividLight, PinLight, HardMix.
+set: Command line utilities now support +set to remove an existing image attribute.
-format: Support additional format specifiers 'g', 'A', 'C', 'D', 'G', 'H', 'M', 'O', 'P', 'Q', 'T', 'U', 'W', 'X', and '@', similar to the major brand.
-operator: New quantum operators ThresholdBlackNegateQuantumOp and ThresholdWhiteNegateQuantumOp These correspond to -operator "Threshold-Black-Negate" and "Threshold-White-Negate".
TIFF: Now support setting the TIFF "Software" tag for users who do not want to admit to using GraphicsMagick.
WebP: All of the WebP encoder encoder options are now supported by -define arguments.
Feature improvements:
Pixel interpolation quality is greatly improved, with minimal impact on performance. Pixel interpolation now also works well given an alpha channel.
WebP: WebP support is now prepared to compile with most WebP library versions and supports all features except for those pertaining to "RIFF" container support.
Performance Improvements:
Non-integral image rotation performance has been improved by about 40%, with lower memory usage as well.
GradientImage: Update image is_grayscale and is_monochrome flags based on gradient color properties.
Windows Delegate Updates/Additions:
PNG: Libpng 1.6.12 - June 12, 2014.
JPEG: libjpeg 9a of January 19, 2014.
FreeType: FreeType 2.5.3 of March 6, 2014.
WebP: webp 0.4.0 of January 20, 2013.
zlib: zlib 1.2.8 of April 28, 2013.
Build Changes:
--without-threads no longer disables use of OpenMP. Use the already existing option --disable-openmp to disable OpenMP.
Makefiles: Include paths are now exceedingly pedantic to make sure that only the required directories are included.
VisualMagick configure: Improve configure program so that it is possible to select QuantumDepth, OpenMP, and 64-bit build via configure dialog boxes as well as options on the command line. Also automatically detects and deals with similarly named files in subdirectories so that WebP support can now build successfully.
Behavior Changes:
MultiplyCompositePixels: Multiply composition now uses SVG interpretation of how alpha should be handled. No longer does a simple multiply of alpha channel.
Composition: The Difference, Darken, Lighten, and HardLight composition operators were modified to support alpha in their computations.
PNG: Using -optimize no longer triggers palette and depth optimizations since their implementations have been problematic.

Tux Paint 0.9.21 features nearly two dozen new Magic tools, as well
as updates to old favorites. Many of these were developed by six
students from around the globe during Google's 2008 Summer of Code
program, under the mentorship of Tux Paint developers.
Exciting new Magic tools include intelligent train tracks that
automatically connect when their paths cross, a realistic rainbow
tool, a fisheye lens effect, edge and silhouette tracing tools,
various string art effects, and a tool to fold the edges of your
drawing up from the corners. There is also a brush that paints with
'toothpaste', and others that paint with confetti, rain, snowballs,
and snowflakes! Additionally, many classic Magic tools (like Blur
and Tint) can now affect the entire drawing, instead of just a
selected area.
Coloring-book style Starter Images are now easier to make. Images
with transparency (alpha channel) are still supported, but
additionally, if no transparent layer is found, Tux Paint will
assume that white is the background color. This means you can now
draw or scan any simple black-and-white image and use it as a Tux
Paint Starter Image!
New in Tux Paint 0.9.21, the Text tool now supports bidirectional
languages like Hebrew and Arabic, thanks to the FriBidi library.
Tux Paint has also been translated to two new languages, Shuswap
and Songhay, and many other translations have been updated.
On Linux, environment variables (like "$HOME") may now be used when
setting directories for saving images or finding data files.
And of course, Tux Paint 0.9.21 incorporates a number of minor
improvements and bug fixes requested by the Tux Paint community.
For example, Tux Paint no longer drops out of fullscreen mode in
Windows if the [Windows] key is pressed (XP, 2000 and Vista only),
and it brings up an error window if it fails to print.

|
|
|
Bump the package revision as it is possible that the broken code compiled
on some platforms but won't work properly.
|
|
|
|
|
|
Note: some of these packages didn't build for me, e.g. osg, so I couldn't
verify them all.

Modern g++ seems to dislike *printf without a constant format string if there
are no other aguuments and was causing compiles to fail. Fixed warning
and patch from Tobias Quathamer.
Manpage spelling fix from Tobias Quathamer.
John Heidemann pointed out that plot doesn't accept modifiers to strings
(though he didn't phrase it that way). The short form is that
plot bullet at x,y
wasn't working. I've adjusted plot to make the string modifiers into
active keywords, which fixes the problem.
Someone named Y T pointed out that there was no mod operator (%). There
is now.
This marks the transition from my home brewed Makefiles to automake-generated
makefiles. A couple largely unused options went away, but with any luck
we still build everywhere.
Robert Daasch submitted a patch to include floor and ceil fuctions.
That's been incorporated. (His patch also included adding a mod
operator, but I'd already done that.)
Added minimal support for dates, by adding versions of strftime and
strptime that return and accept seconds since the unix epoch.
1.43
Bruce Lilly pointed out that g++ 4.3.1 was emitting all sorts of dire
warnings about the hash_map data structure and associated support being
pulled from g++ in the future. SuSe seems to ship with this and there's
no point scaring people (or letting a time bomb tick). Grap now detects
and uses unordered_map if it's present on your system, which stops the
wailing and gnashing of teeth from g++ 4.3.1 . That g++ version also
requires a compiler option to support that include file, which we also
autodetect and use. (This is essentially autodetecting the flags described in
the changes to grap 1.41 below, along with some code changes to make that
actually function correctly.)
A fellow named Fergus had a Cygwin compilation problem as well. His
system apparently had rand but not random (a very rare configuration
these days). This led me to find a corner of the autoconf code that I
apparently hadn't checked sufficiently. If rand was found and a
declaration made in the system files, the grap config stuff failed to
note the declaration and made its own incompatible one. This should be
gone now.
Fergus's system also seemed to be lacking snprintf - which again is very
odd. I hadn't reflected the change to grap sprintf in version 1.23 into
the code that emulates snprintf on systems without it. That code has
been added.
Changed the examples to include a brief tutorial on string matching in
grap. Suggested by John Heidemann.
1.42
There's been a long standing bug with how different versions of pic
interpret the "line from (x,y) then down 5" construct. There was once a
bug report at
http://lists.gnu.org/archive/html/groff/2008-03/msg00003.html
about this. As of version 1.42 grap no longer outputs this pic construct.
Dan Lasley pointed out that the key was incomplete for the bar graph example.
His fix to restore the key is included.
John Heidemann points out that bars in coordinate systems other than the
default just didn't work. This was a bug in my yacc grammer - for
heaven's sake. It's corrected to match the manual page.
For loops were strange in that
.G1
for xx from 15 to 13 do { print "YYY" }
print "ZZZZ"
.G2
would loop infinitely. xx never passes 13. Added a test to make that a
null loop as well as making
.G1
for xx from 13 to 13 do { print "YYY" }
print "ZZZZ"
.G2
print one "YYY". You can still confuse loops, using strange by clauses
- for example "by 0" or "by * -1" but common cases should be covered.
Spotted by a fellow named Yuval.
Found a lurking initializer bug while fixing the for loop thing.
I added references to standard plot strings in a couple places to make
them somewhat easier to find.

This package provides encoder/decoder implementation for DEC SIXEL graphics, and
some converter programs.
SIXEL is one of image formats for printer and terminal imaging introduced by
Digital Equipment Corp. (DEC).
Its data scheme is represented as a terminal-friendly escape sequence.
So if you want to view a SIXEL image file, all you have to do is "cat" it to
your terminal.

#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.

Fixes the build on systems with a native harfbuzz library, where the
library will otherwise be auto-detected.
Add: USE_TOOLS+=pkg-config
Not identified as fixing any real-world problems, but it corrects build
behaviour if buildlinking harfbuzz for diagnostic purposes.
Helps with working around the problems identified in PR pkg/48919.
No PKGREVISION bump - I believe all the problems fixed here prevent this
package from building at all if on an affected platform, and unaffected
platforms will not be affected by these changes.
