In the meantime, libjxl was added to the Tumbleweed distribution, thank you! Would be nice to also have the cjxl and djxl commands, but I downloaded nightly builds separately. Packages, however, do not enable libjxl: - kimageformats - krita - imagemagick - ffmpeg - digikam/kolourpaint/gwenview/okular/photoqt/qview (via kimageformats?) - gthumb (?) Should I report individually for each package to inform KDE/Qt maintainers?
