read_orientation_helper() mapped the irot/imir properties to an EXIF
orientation with a list of conditions that misses several combinations,
e.g. a 90 degrees counterclockwise rotation followed by a mirroring,
which is how iPhone front-camera photos are stored. For those it still
returned true, so libheif was told to ignore the transformations while
Qt got no orientation either, and the image was shown sideways.
The orientation is now chosen by a switch on the rotation and, in each
case, on the mirroring, which is applied after the rotation as MIAF
requires. Other rotation values are left to libheif.
The new read tests cover the twelve rotation and mirroring combinations,
named like the AVIF ones. All of them display the same picture (colored
corners and an "F"): the stored pixels are that picture with the
transformations undone, written as uncompressed HEIF with libheif. Four
of them fail without this change.
libjxl with SIMD disabled (HWY_COMPILE_ONLY_SCALAR) and with
O1 optimization level is very slow for real use,
leading to timeouts.
HWY_COMPILE_ONLY_STATIC enables baseline SIMD, which should be
always supported by current arch. (for example SSE2 on x86_64)
Fixes kimageformats-write-exr test on Alpine Linux armhf, armv7,
loongarch64, ppc64le, riscv64 and s390x.
Working alternatives are increasing fuzziness to 10 or using 64bpp
formats as compareFormat.
- 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.
New option `KIMAGEFORMATS_HEIC_TEST` for testing images with
HEVC codec only.
Existing option `KIMAGEFORMATS_HEIF_TEST` is used for testing other
possible (mostly quite rare) codecs that might be used by HEIF
images - uncompressed, deflate, zlib, brotli, jpeg.
- 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).
