- update to 1.16.1:
* Small maintenance update that fixes building the gdk-pixbuf
loader.
* The source package name has also been changed back to the old
naming scheme.
* Support for HEIFv2 regions (rgan) and user annotations
(udes). This enables to annotate regions in the image with
several geometric primitives and assign user text
descriptions to them. Thank you @bradh for the contributions.
Mask support will be added soon.
* Previously, chroma was downsampled and upsampled with a
simple nearest-neighbor method. We now included the sharp-yuv
chroma downsampling algorithm. This gives improved image
quality when images are downsampled to 4:2:0 and upsampled
with bilinear interpolation. Thank you @maryla-uc for the
contributions.
* The bilinear chroma upsampling and averaging downsampling
algorithms are also new. You can choose what to use.
* We added experimental support for decoding uncompressed
images according to ISO/IEC 23001-17:2023. This is work in
progress and currently decoding only. Thank you @bradh for
the contributions.
* There are new APIs to query the image transformations. Thus,
you may choose to get the original image and apply the
transformations yourself.
* A longstanding bug writing non-compliant 'ispe' boxes (image
size) has been fixed. Files should be standard compliant now.
* When building binary packages, you can now make use of a
CMake presets to set a default configuration.
* The deprecated autotools build files have been removed.
