- 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.
- update to 1.16.0
* 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. 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.
* 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.
* 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.
- Package the optional plugins in separate packages, so it is possible
to install a minimal version of the library without pulling in the
libraries needed by the plugins only.
