Hello, gthumb has heif jpegxl use flags but dependencies were not added yet. I suggest adding something like heif? ( >=media-libs/libheif-1.12.0-r1:= ) jpegxl? ( media-libs/libjxl:= ) I think that new version of libjxl will be released in near future and the rebuild will be probably needed.
What exactly do these library deps add as value to gthumb? I suppose libjxl adds JPEG XL viewing support, but what about HEIF? Would it be mainly used for AVIF support or HEIF in general? Basically as a used I wouldn't know to really make the connection between HEIF and AVIF here, so I'm unsure about this widespread use of IUSE=heif.
libheif is used by gthumb to load HEIF/HEIC and AVIF images. libjxl is used to load JPEG XL (*.jxl) images. HEIF and AVIF use similar container (which is ISO BMFF based, like MP4), but HEIF use pixel data compressed with h265/HEVC coded and AVIF use free AV1 codec. If you want AVIF support in GIMP, you need to add the heif use flag too. libheif can be built in such way that it support both HEIF and AVIF or only one of them. BTW, gthumb was able to load AVIF images even before they added native loading support via libheif. AVIF loading worked via gdk-pixbuf plug-in installed by libavif.
Crap, looks like I added the flags and wiring but not the dependencies.
