Release Date: 2020-10-01 // over 3 years ago

  • 🚀 This is the latest monthly instalment of the current supported production release series. It is API and ABI compatible with prior 2.2 releases.

    🚀 Release 2.2.7 (1 Oct 2020) -- compared to 2.2.6

    • oiiotool new command: --pastemeta takes two images as arguments, and
      📇 appends all the metadata (only) from the first image onto the second
      📇 image's pixels and metadata, producing a combined image. #2708
    • TIFF: Fix broken reads of multi-subimage non-spectral files (such as
      photometric YCbCr mode). #2692
    • Python: When transferring blocks of pixels (e.g., ImageInput.read_image()
      or ImageOutput.write_scanline()), "half" pixels ended up mangled into
      uint16, but now they use the correct numpy.float16 type. #2694
    • Python: The value passed to attribute(name, typedesc, value) can now be
      a tuple, list, numpy array, or scalar value. #2695
    • 🛠 IBA::contrast_remap() fixes bug that could crash for very large images
      #2704
    • Warn about recommended minimum versions of some dependencies.
    • Windows fix: correct OIIO_API declaration on aligned_malloc, aligned_free
      of platform.h. #2701
    • 🛠 Fix oiiotool crash when --resize was used with multi-subimage files. #2711
    • 🐛 Bug fix in Strutil::splits and splitsv: when input is the empty string,
      the split should return no pieces. #2712
    • 👌 Support for libheif 1.9. #2724
    • TIFF: Fix spec() and spec_dimensions() for MIPmapped TIFF files, they
      did not recognize being asked to return the specs for invalid subimage
      indices. #2723
    • TIFF: add ability to output 1bpp TIFF files. #2722
