libavif Files

1.3.0 - 2025-05-09

Added since 1.2.1

• Add grayscale conversions in avifImageRGBToYUV and avifImageYUVToRGB.
• Add avifRGBFormatIsGray to check whether an avifRGBFormat is gray.

Changed since 1.2.1

• Reject the conversion in avifenc from non-monochrome/monochrome to monochrome/non-monochrome when an ICC profile is present and not explicitly discarded.
• Forbid encoding with AVIF_MATRIX_COEFFICIENTS_IDENTITY and AVIF_PIXEL_FORMAT_YUV400 to be AV1 spec compatible.
• Do not go through RGB when reading/writing a grayscale PNG/JPG images in avifenc/avifdec
• Ignore tmap items not present in grpl box
• Assume any id is present in only one altr group as per spec.
• avifpng.c: support ImageMagick app1 exif text data
• avifjpeg.c: check for uint32_t overflow before add
• Update googletest.cmd/LocalGTest.cmake: v1.16.0
• Update libjpeg.cmd/LocalJpeg.cmake: 3.1.0
• Update libsharpyuv: v1.5.0
• Update libxml2.cmd/LocalLibXml2.cmake: v2.14.0
• Update libyuv.cmd/LocalLibyuv.cmake: 4db2af62d (1909)
• Update LocalRav1e.cmake: cargo-c v0.10.12
• Update zlibpng.cmd: libpng 1.6.47
• Fix wrong Exif orientation set in JPEG or PNG output by avifdec when the input AVIF file has an ImageRotation property with angle set to 1 or 3, has no ImageMirror property, and carries an Exif chunk. Note that Exif orientation is usually ignored in PNG files, so this mainly impacts JPEG files.
• Encoder: fix ispe property for tmap with grid.
• Decoder: check the ispe property of tmap items.
• Allow lowercase GUIDs in XMP when reading JPEG files.
• Update aom.cmd/LocalAom.cmake: v3.12.1
• Change avifenc to start in automatic tiling mode.
• Always forward Unspecified (2) CICP color primaries, transfer characteristics, and matrix coefficients to the AV1 encoder. Rely on the 'colr' box instead.
• Declare *RowBytes as size_t in avifImageRGBToYUV()
• Check ftell returned value in avifjpeg.c
• Add integer overflow checks to makeRoom.
• LocalJpeg.cmake: Support multi-config generators.
