This marks the official start of the OIIO 3.0 era. Now, 3.0 is the fully-supported production release family, and will be guaranteed API, ABI, and link back-compatible for all future 3.0.x releases. Now, 2.5 will be the obsolete release family that only gets important fixes.

Release 3.0 (Nov 8, 2024) -- compared to 2.5.16.0

Executive Summary / Highlights:

  • Updated minimum toolchain: C++17/gcc9.3, Python 3.7, CMake 3.18.2, and raised min versions of most library dependencies.
  • New image format support: JPEG XL, R3D.
  • oiiotool new commands: --cryptomatte-colors, --demosaic, --buildinfo, --ocionamedtransform, --popbottom, --stackreverse, --stackclear, --stackextract; improved --for behavior for reverse direction.
  • Lots of long-deprecated API calls have been removed entirely. Please see the detailed deprecation list.
  • New ImageBufAlgo: perpixel_op(), demosaic(), ocionamedtransform().
  • ImageBuf now by default does not use ImageCache to mediate file images, unless you explicitly ask for it.
  • ImageCache & TextureSystem now use shared_ptr for creation, not raw pointers. And they have been de-virtualized, for easier future expansion flexibility without breaking ABI for any small change.
  • Improved and more consistent color space name nomenclature.
  • Build system now is capable of auto-downloading and building several of the most important dependencies if they are missing at build time.
  • Please note that the development branch in the GitHub repo is now named main instead of master.

Full details of all changes follow.

New minimum dependencies and compatibility changes:

  • C++: Move to C++17 standard minimum (from 14), which also implies a minimum gcc 9.3 (raised from 6.3), clang 5 (though we don't test or support older than clang10), Intel icc 19+, Intel OneAPI C++ compiler 2022+. #4199 (2.6.2.0)
  • Python: 3.7 minimum (from 2.7). #4200 (2.6.2.0)
  • CMake: 3.18.2 minimum (from 3.15) #4472 (3.0.0)
  • Boost: Is no longer a dependency! #4191 (by Christopher Kulla) #4221 (by Christopher Kulla) #4222 #4233 (2.6.2.0)
  • ffmpeg: 4.0 minimum (from 3.0) #4352 (2.6.3.0)
  • Freetype: 2.10 minimum (from no previously stated minimum, but we had been testing as far back as 2.8) #4283 (2.6.2.0)
  • GIF: 5.0 minimum for giflib (from 4.0) #4349 (2.6.3.0)
  • libheif: 1.11 minimum (from 1.3) #4380 (2.6.3.0)
  • LibRaw: Raise minimum LibRaw to 0.20 (from 0.18) #4217 (2.6.2.0)
  • libtiff: 4.0 minimum (from 3.9) #4296 (2.6.2.0)
  • OpenColorIO: Make OpenColorIO a required dependency and raise the minimum to 2.2 (from 1.1). #4367 (2.6.3.0)
  • OpenEXR/Imath: minimum raised to 3.1 (from 2.4) #4223 (2.6.2.0)
  • OpenCV: 4.0 minimum (from 3.x) #4353 (2.6.3.0)
  • OpenVDB: Raise OpenVDB minimum to 9.0 #4218 (2.6.2.0)
  • PNG: 1.6.0 minimum for libPNG (from 1.5.13) #4355 (2.6.3.0)
  • Pybind11: 2.7 minimum #4297 (2.6.2.0)
  • Robin-map: 1.2.0 minimum #4287 (2.6.2.0)
  • WebP: 1.1 minimum (from 0.6.1) #4354 (2.6.3.0)

⛰️ New features and public API changes:

  • New image file format support:
    • JPEG XL: Initial JPEG XL support for image input/output #4055 (by Peter Kovář) #4252 (by Vlad (Kuzmin) Erium) (2.6.2.0) #4310 (by Vlad (Kuzmin) Erium) (2.6.3.0)
    • R3D: Add initial support to read R3D files. Note that this capability will only be enabled if OIIO is built with the R3D SDK installed and available to be found by the build system. #4216 (by Peter Kovář) (2.6.2.0)
  • oiiotool new features and major improvements:
    • --cryptomatte-colors takes the name of a cryptomatte set of channels, and produces a color-coded matte in which each ID gets a distinct color in the image. This can be useful for visualizing the matte, among other things. #4093 (2.6.0.2)
    • --demosaic takes 1-channel Bayer patterns and turn them into
      demosaiced 3-channel images #4366 (by Anton Dukhovnikov) (2.6.3.0) #4419 (by Anton Dukhovnikov) (2.6.6.0)
    • --buildinfo command prints build information, including
      version, compiler, and all library dependencies. #4124 (2.6.0.3) #4150 (2.6.0.3)
    • --ocionamedtransform: Implement support for OCIO NamedTransforms #4393 (by zachlewis) (2.6.3.0)
    • Several new stack manipulation commands: --popbottom discards the bottom element of the stack, --stackreverse reverses the order of the whole stack, --stackclear fully empties the stack, --stackextract <index> moves the indexed item from the stack (index 0 means the top) to the top. #4348 (2.6.3.0)
    • --for improvements: correct reverse iteration behavior if the step value is negative, or if there is no step value but the start value is greater than the end value. (#4348) (2.6.3.0)
    • Expression evaluation improvements: BOTTOM refers to the image on the bottom of the stack, IMG[expression] is now supported (previously only numeric literals were accepted as the index), check that label/variable names #4334 (2.6.3.0)
    • oiiotool now by default 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. This tends to improve performance.
      #3986 (2.6.0.1, 2.5.3.1)
    • Change command line embedding for oiiotool & maketx output, by default hiding the command line for security reasons. It can be re-enabled with --history. #4237 (2.6.2.0)
  • Command line utility new features:
    • idiff: Allow users to specify a directory as the 2nd argument #4015 (by David Aguilar) (2.6.0.1)
    • iv: Implement Directory Argument Loading for iv #4010 (by Chaitanya Sharma) (2.6.0.1)
    • iv: Split off the current image in iv into a separate window #4017 (by Anton Dukhovnikov) (2.6.0.1)
    • iv: OCIO color managed display #4031 (by Anton Dukhovnikov) (2.6.0.2)
    • iv: Iv shows constant brown and GL error messages on start-up. #4451 (by David Adler) (2.6.6.0)
    • iv: Initialize variables before we use them. #4457 (by Bram Stolk) (2.6.6.0)
    • iv: Add iv data and display windows overlay feature #4443 (by Andy Chan) (2.6.6.0)
  • New global attribute queries via OIIO::getattribute():
    • "build:platform", "build:compiler", "build:dependencies" #4124 (2.6.0.3)
    • "build:simd" is the new preferred synonym for the old name "oiio:simd" #4124 (2.6.0.3)
  • ImageBuf/ImageBufAlgo:
    • ImageBuf now has span-based constructors for the variety where it "wraps" a user buffer. This is preferred over the constructor that takes a raw pointer (which is considered deprecated). #4401 (2.6.6.0)
    • New span-based versions of get_pixels, set_pixels, setpixe...

OpenImageIO v3.0.0.0-beta1

Pre-release

OpenImageIO version 3.0 is now in beta, tagged as "v3.0.0.0-beta1". We will try very hard not to make any further incompatible API or ABI changes between now and the final release, unless it is absolutely necessary to fix an important problem identified during beta testing. We are aiming for Nov 1 to tag a non-beta (pending no critical problems being found), so please try building and testing the beta so we are sure to find any problems.

Some highlights of this year's release are:

  • Updated minimum toolchain: C++17/gcc9.3, Python 3.7, CMake 3.18.2, and raised min versions of most library dependencies.
  • New image format support: JPEG XL, R3D.
  • oiiotool new commands: --cryptomatte-colors, --demosaic, --buildinfo, --ocionamedtransform, --popbottom, --stackreverse, --stackclear, --stackextract; improved --for behavior for reverse direction.
  • Lots of long-deprecated API calls have been removed entirely. Please see the detailed deprecation list.
  • New ImageBufAlgo: perpixel_op, demosaic, ocionamedtransform.
  • ImageBuf now by default does not use ImageCache to mediate file images, unless you explicitly ask for it.
  • ImageCache & TextureSystem now use shared_ptr for creation, not raw pointers. And they have been de-virtualized, for easier future expansion flexibility without breaking ABI for any small change.
  • Improved and more consistent color space name nomenclature.
  • Build system now is capable of auto-downloading and building several of the most important dependencies if they are missing at build time.
