Release 2.3.12 (1 Feb 2022) -- compared to 2.3.11

  • oiiotool: Don't give spurious warnings about no output when the --colorcount
    or --rangecheck commands are used. #3262
  • oiiotool --pattern checker fixed behavior so that if only the checker
    width was specified but not the height, height will be equal to width. #3255
  • oiiotool --point lets you set individual pixels. #3256
  • Python: A new ImageBuf constructor was added that takes only a NumPy
    ndarray, and deduces the resolution, channels, and format (pixel data type)
    from the shape of the array. #3246
  • Python: Implement ROI.copy(). #3253
  • Python: ImageSpec and ParamValueList now support 'key' in spec,
    del spec['key'], and spec.get('key', defaultval) to more fully emulate
    Python dict syntax for manipulating metadata. #3252 (2.3.12/2.4.0)
  • Python bug fix: fix clamp() when the min or max are just a float. Now
    it uses that one value for all channels, instead of using it only for
    the first channel. #3265
  • ImageSpec gained an additional constructor that takes a string
    representation of the pixel data type (where it used to insist on a
    TypeDesc), such as ImageSpec(640, 480, 3, "uint8"). This is especially
    helpful for new/casual users, or when you want code to be maximally
    readable. #3245
  • Imagepec::getattribute() new query token "format" can retrieve the pixel
    data type. #3247
  • IBA::make_texture(): ensure that "maketx:ignore_unassoc" is honored. #3269
  • Support an additional UDIM pattern <UVTILE>, which is specified by
    MaterialX. #3280
  • TIFF: support 16-bit palette images. #3260
  • TIFF: Gracefully handle missing ExtraSamples tag. #3287
  • Targa: Better interpretation of TGA 1.0 files with alpha that is zero
    everywhere. Be more consistent with Targa attributes all being called
    "targa:foo". Add "targa:version" to reveal whether the file was TGA 1.0
    or 2.0 version of the format. #3279
  • simd.h: Better guards to make it safe to include from Cuda. #3291 #3292
  • Fix bugs in the build_opencolorio.bash script, did not correctly handle
    installation into custom directories. #3278
  • Fixes to FindOpenColorIO.cmake module, now it prefers an OCIO exported cmake
    config (for OCIO 2.1+) unless OPENCOLORIO_NO_CONFIG=ON is set. #3278
  • Docs: The ImageBufAlgo chapter now has examples for C++, Python, and
    oiiotool for almost every operation. #3263
