- ORA/KRA: merged in a single plugin (KRA)
- ORA: removed standalone plugin
- KRA: use of logging category
- KRA: add metadata support by processing the embedded `documentinfo.xml`
- Improved signature lookup (see MR !17) and added test case
When 1st parsing ends with invalid EXIF payload error,
we try 2nd time again while ignoring the EXIF metadata.
Dropped support for legacy 0.x libavif versions,
libavif 1.0.0+ is now required for the AVIF support.
libheif retains the heif_reader pointer after
heif_context_read_from_reader returns. The callback table was scoped
to the non-sequential branch and could be destroyed before
tiled image decoding used it from worker threads.
Give the callback table static storage duration.
BUG: 523105
Following compromises were chosen to ensure that saved AVCI
is decodable using OpenH264 decoder:
8-bit only, YUV420 subsampling, lossy compression,
large images encoded via image grid.
We were errorneously returning true here, as we do not have any more
images to jump to. If we only have one image, return false.
This avoids the avif handler getting stuck in a loop with only single images.
BUG: 521200
FIXED-IN: 6.28
- Fixes a writing issue for float values less than 1
- Fixes a missing definition of `EXIF_DATETIMEDIGITIZED` tag
- Adds support for some common camera shot metadata
- Adds missing metadata to writing tests
The following plugins automatically gain support for the new metadata: AVIF, IFF, HEIF, JXL, JXR, PSD and TGA (V2E).
The new metadata added with this patch is usually saved by smartphones (e.g. iPhone or Google Pixel).
Previously there was no limit for uncompressed metadata,
but when compressed metadata required buffer larger than 4MB,
image decoding stopped.
Now the plugin discards/skips metadata boxes larger than 8MB
without stopping image decoding.
If size of compressed box is above 8MB,
we do not attempt to decompress it.
File with compressed metadata could be rejected only in rare cases
when the decompression buffer grows above 32MB (four times 8M).
