0.6.13
🤦 Hotfix release to remove a "work-in-progress" pyproject.toml file
that was mistakenly included with Wand 0.6.12 sdist package.
0.6.12
The 0.6.12 release includes some minor bug fixes, adds a few
composite operators, and updates Sphinx build versions (used for
documentation).
v1.1.1 (2023-09-16)
-------------------
This release adds support for CPython 3.12 and reinstates the release of
Windows 32-bit wheels following NumPy's intention to continue doing so.
There is a new keyword argument ``webdriver`` to the ``BokehRenderer`` save
functions to reuse the same Selenium WebDriver instance across multiple calls.
v3.8.1
This is the first bugfix release of the 3.8.x series.
This release contains several bug fixes and adjustments:
Bump setuptools required version because of setuptools_scm v8
Update find_nearest_contour and revert contour deprecations
allsegs and allkinds return individual segments
Restore default behavior of hexbin mincnt with C provided
Try/except import of Axes3D
Ensure valid path mangling for ContourLabeler
BLD: Remove development dependencies from sdists
FIX 2-tuple of colors in to_rgba_array
Fix issue with non-string labels and legend
Fix issue with locale comma when not using math text
Various type hinting improvements
Various documentation improvements
Improvements to the MacOS backend
v0.13.0 (September 2023)
------------------------
This is a major release with a number of important new features and changes. The highlight is a major overhaul to seaborn's categorical plotting functions, providing them with many new capabilities and better aligning their API with the rest of the library. There is also provisional support for alternate dataframe libraries like `polars <https://www.pola.rs>`_, a new theme and display configuration system for :class:`objects.Plot`, and many smaller bugfixes and enhancements.
Updating is recommended, but users are encouraged to carefully check the outputs of existing code that uses the categorical functions, and they should be aware of some deprecations and intentional changes to the default appearance of the resulting plots (see notes below with |API| and |Defaults| tags).
This follows the recommended bootstrap method (flit_core, build, installer).
However, installer installs different files than pip, so update PLISTs
for all packages using wheel.mk and bump their PKGREVISIONs.
The last bit of C has fallen
gif.ski was originally meant to be just the highest-quality GIF maker, but over
time I also made it generate smaller files. Now it's probably the most
technically advanced GIF compressor, if I say so myself.
The key to good GIF compression is making LZW algorithm lossy. In 2014, I wrote
a patch that added lossy compression to gifsicle. Gifsicle is a GIF optimization
tool created in 1998, so I can't blame them for not using Rust. Of course,
I wanted to use that lossy compression in gif.ski too, so I've made gifsicle
usable as a Rust crate.
Rust already had a gif encoder, so bringing all of the gifsicle's code seemed
unnecessary. I only wanted the lossy LZW bit, so I've made the Rust gif library
accept data from other compressors, and used only a couple of gifsicle's C
functions for compression.
The lossy LZW compressor was still my 2014 hacked-together C — until yesterday.
I've rewritten it in Rust.
The rewritten code gives exactly the same, bit-identical output. Usually, when
people rewrite projects it's hard to compare results to the original, because
the rewrites change and reinvent things along the way. This time it's apples to
apples. I made sure it works exactly the same. I even reimplemented an integer
overflow bug and quirks caused by use linked lists. The result is… the same
performance, and the same binary size, within margin of error. You don't need
to rush to upgrade! On one hand this isn't surprising — it's the same algorithm,
and Rust has C-like performance as advertised. OTOH I used mostly idiomatic
Rust, and did not try to make it super optimized. The original C code did clever
things with memory pools and linked lists, and I've swapped it all for Vecs in
enums.
Aside from ffmpeg, which I'm not rewriting, gif.ski is now 100% pure Rust. It
makes it a bit easier to build it. The x86-64 MUSL/Linux binary has been built
on my ARM Mac. Since the code is now in a form I find easier to refactor, later
I'll work on improving quality of its lossy dithering, because for some reason
I'm determined to squeeze every last possible bit out of this prehistoric video
format.
Instead of depending on one of the removed packages (that are now included
in the base Python packages), include batteries-included.mk to require
a Python version that supplies them.
Remove now included packages.
Bump PKGREVISION.
tk will not be a default dependency of the batteries-included Python packages,
and srcdist.mk needs to be switched from distutils to some other method of
installing the modules separately. Until this is done, there is no py-Tk
for Python 3.12.

3.0.1
The x86-64 SIMD functions now use a standard stack frame, prologue, and epilogue so that debuggers and profilers can reliably capture backtraces from within the functions.
Fixed two minor issues in the interblock smoothing algorithm that caused mathematical (but not necessarily perceptible) edge block errors when decompressing progressive JPEG images exactly two MCU blocks in width or that use vertical chrominance subsampling.
Fixed a regression introduced by 3.0 beta2[6] that, in rare cases, caused the C Huffman encoder (which is not used by default on x86 and Arm CPUs) to generate incorrect results if the Neon SIMD extensions were explicitly disabled at build time (by setting the WITH_SIMD CMake variable to 0) in an AArch64 build of libjpeg-turbo.

Following upstream guidance, tools that are no longer supported are
not built by the package. As raised on tech-pkg on October 2, with no
objections or even comments.
Upstream NEWS content:
This version removes a big number of utilities that have suffered from
lack of maintenance over the years and were the source of various
reported security issues. See "Removed functionality" below for the
list of removed utilities. Starting with libtiff v4.6.0, the source
code for most TIFF tools (except tiffinfo, tiffdump, tiffcp and
tiffset) was discontinued, due to the lack of contributors able to
address reported security issues. tiff2ps and tiff2pdf source code has
been moved in a unsupported category, no longer built by default, but
are still part of the the source distribution. Other retired utilities
are in a archive/ directory, only available in the libtiff git
repository. Issues related to unsupported and archived tools will no
longer be accepted in the libtiff bug tracker.
The usual bugfixes.
Changelog:
Release 2.5 (2.5.4.0, Oct 1, 2023) -- compared to 2.4
New minimum dependencies and compatibility changes:
CMake: minimum needed to build OpenImageIO has been raised from 3.12 to
3.15. #3924 (2.5.2.1)
LibRaw: minimum has ben raised from 0.15 to 0.18.
#3921 (2.5.2.1)
The new OpenEXR minimum is 2.4 (raised from 2.3).
#3928 (2.5.2.1)
The new fmt library minimum is 7.0 (raised from 6.1)
#3973 (2.5.3.0)
The new libjpeg-turbo (if used; it is optional) has been raised to
2.1. #3987 (2.5.3.1-beta2)
ï¸ New features and public API changes:
TextureSystem color management: #3761 (2.5.1.0)
TextureOpt and TextureOptBatch have a new field, colortransformid,
which supplies an integer ID for a requested color space transformation
to be applied as texture tiles are read. The default value 0 means no
transformation because the texture is presumed to be in the working
color space (this is the old behavior, and most performant). Tiles from
the same texture file but using different color transformations are
allowed and will not interfere with each other in the cache.
New TextureSystem::get_colortransform_id(from, to) maps from/to named
color spaces to a color transform ID that can be passed to texture
lookup calls.
ImageCache::get_image_handle and TextureSystem::get_texture_handle
now take an optional TextureOpt* parameter that can supply additional
constraints (such as color transformation) that TS/IC implementations
may wish to split into separate handles. This is currently not used, but
is reserved so that the API doesn't need to be changed if we use it in
the future.
texture.h defines symbol OIIO_TEXTURESYSTEM_SUPPORTS_COLORSPACE that
can be tested for existence to know if the new fields are in the
TextureOpt structure.
Extensive support for OpenColorIO 2.2 functionality and improved color
management:
When building against OCIO 2.2, you can specify/use the new "built-in"
configs, including using ocio://default, which will automatically be
usd if no config is specified and the $OCIO variable is not set #3662#3707 (2.5.0.0)
OIIO tries to find and honor the common color space aliases
"scene_linear", "srgb", "lin_srgb", and "ACEScg". When building against
OCIO 2.2+, it will know which of any config's color spaces are
equivalent to these, even if they are named something totally different,
thanks to the magic of OCIO 2.2 built-in configs. For older OCIO (2.1 or
older), it is less robust and may have to make best guesses based on the
name of the color spaces it finds. #3707 (2.5.0.0)
#3995 (2.5.3.2-rc1)
New ColorConfig methods: getAliases() #3662; isColorSpaceLinear()
#3662; resolve(name) turns any color space name, alias, role, or OIIO
name (like "sRGB") into a canonical color space name;
equivalent(n1,n2) returns true if it can tell that the two names
refer, ultimately, to equivalent color spaces #3707 (2.5.0.0)
New ImageSpec::set_colorspace() method is a more thorough way to set
the color space data than simply setting the "oiio:ColorSpace" metadata
(though it also does that). #3734 (2.5.0.1)
Improve OIIO's ability to guess which of the config's color space names
are aliases for common spaces such as srgb, lin_srgb, and acescg (quite
robustly if using OCIO >= 2.2, even for totally nonstandard names in the
config). #3755 (2.5.0.1)
New ColorConfig::getColorSpaceIndex() looks up a color space index by
its name, alias, or role. #3758 (2.5.0.1)
oiiotool new commands and features:
New --iccread and --iccwrite add an ICC profile from an external
file to the metadata of an image, or extract the ICC profile metadata
and save it as a separate file. #3550 (2.5.0.0)
New --parallel-frames parallelizes execution over a frame range rather
than over regions within each image operation. This should be used with
caution, as it will give incorrect results for an oiiotool command line
involving a frame range where the iterations have a data dependency on
each other and must be executed in order. But in cases where the order
of frame processing doesn't matter and there are many more frames in the
sequence than cores, you can get a substantial performance improvement
using this flag. #3849 (2.5.2.0)
New --no-error-exit causes an error to not exit immediately, but
rather to try to execute the remaining command line operations. This is
intended primarily for unit tests and debugging. #3643 (2.5.0.0)
New --colorconfiginfo prints the full inventory of color management
information, including color space aliases, roles, and with improved
readability of output for larger configs. #3707 (2.5.0.0)
The --resize command takes new optional :from=, :to=, and
:edgeclamp= modifiers to give more general and fine control over the
specific correspondence between display windows in the input image and
resized destination image (including allowing partial pixel offsets).
#3751#3752 (2.5.0.1)
New expression substitution additions:
New syntax for retrieving metadata {TOP[foo]} is similar to the
existing {TOP.foo}, if there is no foo metadata found, the
former evaluates to an empty string, whereas the latter is an error.
#3619 (2.4.5/2.5.0.0)
{NIMAGES} gives current stack depth
#3822 (2.5.2.0)
{nativeformat} is the pixel data format of the file, whereas the
existing format has always returned the data type used in memory.
Also, METANATfull metadata
keywords for native file metadata, comapred to the previously
existing META and METABRIEF which we now clarify reflect the
in-memory representation. #3639 (2.5.0.0)
--ociodisplay now takes an optio (2.5.0.0)
New -otex optional modifier forcefloat=0 can improve memory use for
enormous texture conversion.
#3829 (2.5.2.0)
--printinfo now takes new optional modifiers: :native=1 ensures
that the metadata printed the file, not changed by the way the
image is stored in memory (for example, it may have been converted to
a more convenient in-memory data type); :verbose=1 prints verbose
stats even if -v is not used; :stats=1 prints full pixel ul for normal maps.
#3945 (by Vlad (Kuzmin) Erium) (2.5.3.0)
ImageBufAlgo additions:
A new flavor of ociodisplay() now contains an inverse parameter.
#3650 (2.5.0.0)
New normalize() normalizes image that represent 3D vehelpful for normal maps.
#3945 (by Vlad (Kuzmin)
Erium) #3963 (2.5.3.0)
ImageBuf changes:
ImageBuf: Only back IB with IC when passed an IC
#3986 (2.5.3.1-beta2)
ImageInput / ImageOutput:
New ImageOutput::check_open() method can be used by format writers
authors to centralize certain validity tests so they don't need to be
implemented separately for each file type. This is not meant to be
called by client application code, only by format writer authors. #3686
(2.5.0.0)
Add an ImageInput::valid_file(IOProxy) overload
#3826 (by Jesse Y)
(2.5.2.0) and implement its overloads for DDS, PSD, and WEBP
#3831 (by Jesse Y)
(2.5.2.0)
New ImageOutput::check_open() and ImageInput::open_check() can be
used by format reader/writer authors to centralize certain validity
tests so they don't need to be implemented separately for each file
type. This is not meant to be called by client application code, only by
format reader/writer authors.

OIIO::print() exposes Strutil::print() in the main OIIO namespace.
#3667 (2.4.6/2.5.0.0)
OIIO::getattribute() new queries:
font_list, font_file_list, font_dir_list return, respectively, the
list of fonts that OIIO found, the list of full paths to font files, and
the list of directories searched for fonts. All return a single string
that is a semicolon-separated list of the items. #3633 (2.5.0.0)
opencolorio_version returns the human-readable (e.g. "2.2.0") version
of OpenColorIO that is being used. #3662 (2.5.0.0)

Python bindings:
Add ability to getattribute() of int64 and uint64 data #3555 (2.5.0.0)
Fixed ability to add and retrieve uint8[] metadata, which on the
python side will be numpy arrays of type uint8 (dtype='B'). This is
important for being able to set and retrieve "ICCProfile" metadata.
#3556 (2.5.0.0)
Eliminate redundant code in Python IBA bindings #3615
Improve error messages for when passing incorrect python array sizes.
#3801 (2.5.1.0)
Fix arithmetic overflow in oiio_bufinfo (Python interop) #3931 (by Jesse Yurkovich) (2.5.2.0)
ImageBuf improvements:
Fixes to subtle bugs when ImageBuf is used with IOProxy. #3666
(2.4.6/2.5.0.0)
Auto print uncaught ImageBuf errors. When an IB is destroyed, any errors
that were never retrieved via geterror() will be printed, to aid users
who would not notice the errors otherwise.
#3949 (2.5.3.0)
oiiotool now does immediate reads without relying on an ImageCache,
unless the --cache option is used, which now both enables the use of
an underlying IC as well as setting its size.
#3986 (2.5.3.1-beta2)

v2.0.1
This is a patch release containing the following fixes and minor enhancements:
PR #1303, Update the After Effects and Photoshop plug-ins to OCIO v2.
PR #1352, Fix a problem with allocation vars not being used for the legacy GPU processing path. This provides a new getOptimizedLegacyGPUProcessor call for developers to access the legacy GPU processing (although you should be using the new GPU processor anyway!) and deprecates the previous CreateLegacyShaderDesc method.
PR #1387, Fix an issue where the environment section of the config was not being validated correctly for vars without a default. This also introduces stricter rules for validation of this part of the config and prevents a possible crash affecting both v1 and v2.
PR #1394, After Effects and Photoshop plug-in build updates.
PR #1370, Fix a minor issue with how CDL ops are optimized.
PR #1365, Enable gcc -Wextra build flag and clean up the resulting warnings.
PR #1353, Re-enable support for negative stride values for packed and planar ImageDescs.
PR #1351, Improve C++ version detection and fix some compilation issues.
PR #1350, Fix and update 'setup_ocio' script.
PR #1339, Correct a typo in the OCIO_USER_CATEGORIES environment variable name.
PR #1338, Fix an issue with the RPATH that was impacting the Python binding.
PR #1336, Improvements to cmake scripts and remove the OCIO_ADD_EXTRA_BUILTINS flag.
PR #1306, Correct the minimum GLSL version specified in some places (is now GPU_LANGUAGE_GLSL_1_2).
v2.0.0
This is the official release of OpenColorIO v2! The noteworthy changes relative to v2.0.0rc1 are:
PR #1291, Fixed a bug in the single-pixel applyRGB call.
PR #1281, Additional ACES Built-in Transforms -- The built-ins now include all transforms identified by the config working group for the initial ACES config, including all of the ACES Output Transforms.
PR #1280, Add to Python binding Uniform_Float3 and setStrictParsingEnabled.
PR #1277, Fixed pybind issue to allow children of Transform class to have the correct type.
PR #1275, Restructure PyOpenColorIO -- Completed PyGpuShaderDesc and moved declarations. Fixed a number of issues with the Python documentation.
PR #1274, Added lots of new Python unit tests, adjusted a few bindings as a result. Reserved some enums for future work.
PR #1272, Avoid NaN values during Lut1D composition.
PR #1271, Python dynamic property fixes and added unit tests. Warn if more than one property is active.
PR #1270, Modify Python LogCameraTransform and FixedFunctionTransform constructors to require arguments. Direct operator<< to Python repr rather than str.
PR #1268, Make shader textures available via the Python API.
PR #1267, Add constants for new roles to the API. Have parseColorSpaceFromString include inactive spaces. Modify ociocheck to warn if roles are missing, rather than error. Fix exception propagation issue from FileRules.
PR #1266, Use OIIO-provided CMake find module to fix build issue.
v2.0.0-rc1
This is the first release candidate for OCIO v2. The final release is about two weeks away, we request people test this thoroughly and help us find any issues. Here are the noteworthy changes relative to beta2:
PR #1241, Color Space Aliases -- It is now possible to define several alternate names for a color space, for example, a full name and an abbreviated name appropriate for use in image file paths. An optional "name" attribute was also added to the config.
PR #1220, App Helpers and Category improvements -- The App Helpers functions to ease use of the library have been moved into OCIO core. Also, the options for filtering color spaces based on category is now more powerful, implementing issue #1222.
PR #1197, New API Docs implementation -- This overhauls the way the API documentation for both C++ and Python are generated. Contributors now need to manually update the frozen Python .rst files and should review the issue for details.
PR #1249, Improved Python apply functions -- This fixed several Python applyRGB issues and the unit test for PyCPUProcessor now requires NumPy.
PR #1244, Improved version handling and config synonyms -- The parser will now throw if reading a minor version higher than current (i.e. a config version 2.1 or higher will now throw). This also fixed a bug when writing v1 configs that caused them to not load correctly. Several syntax enhancements requested related to view transforms were added: - The from/to_reference color space attributes are now written as from/to_scene_reference in v2 configs, although the old syntax is also supported. - The config also now has an attribute to identify the default view transform.
PR #1221, CDLTransform cleanup -- The code for reading and writing CDLs was refactored and the API changed so that they are written more like CLF and CTF files. The write method on Processor was moved to GroupTransform. The way CDL metadata is handled was made more consistent with CLF/CTF. Files with several CDLS (e.g. ccc) may now be loaded into a single GroupTransform.
PR #1245, Finish inversion of new look ops -- This complete the work on issue #1100, these operators all work in both forward and inverse direction.
PR #1251, Fix ACEScc and XYZ built-in transforms -- Addresses issues with several built-in transforms.
PR #1252, Misc fixes -- The ColorSpaceMenuHelpers code no longer warns on v1 configs. An edge case of using LegacyViewingPipeline with named transforms was addressed.
PR #1214, Minor file rules fixes.
v2.0.0-beta2
This is the second beta for OCIO v2. The release candidate is not far off, we request people test this thoroughly and help us find any issues. Here are the noteworthy changes relative to beta1:
PR #1189, Named Color Transforms -- It is now possible to include color transforms in a config separately from color spaces.
PR #1229, Data bypass fix -- Critical bug fix for an issue where conversions on data color spaces were sometimes not bypassed.
PR #1205, Remove dynamic properties from configs -- It is not possible to use dynamic properties in configs, configs are intended to be fixed representations.
PR #1228, Bump pybind11 required version to 2.6.1 -- Moving from 2.4.3 to 2.6.1 removes a dependency that was causing build issues.
PR #1204, Some API cleanup -- Capitalization change for three functions used for iterating over available LUT file formats.
PR #1208, Remove the 'unknown' shader language -- Minor cleanup of GPU renderer API.
