JPEG XL GDK Pixbuf
The plugin may already have been installed when following the instructions from the Installing section of BUILDING.md, in which case it should already be in the correct place, e.g.
Otherwise we can copy it manually:
sudo cp $yourbuilddirectory/plugins/gdk-pixbuf/libpixbufloader-jxl.so /usr/lib/x86_64-linux-gnu/gdk-pixbuf-2.0/2.10.0/loaders/libpixbufloader-jxl.so
Then we need to update the cache, for example with:
sudo /usr/lib/x86_64-linux-gnu/gdk-pixbuf-2.0/gdk-pixbuf-query-loaders --update-cache
In order to get thumbnails with this, first one has to add the jxl MIME type, see
[../mime/README.md](../mime/README.md).
Ensure that the thumbnailer file is installed in the correct place,
`/usr/share/thumbnailers/jxl.thumbnailer` or `/usr/local/share/thumbnailers/jxl.thumbnailer`.
The file should have been copied automatically when following the instructions
in the [Installing section of README.md](../../README.md#installing), but
otherwise it can be copied manually:
sudo cp plugins/gdk-pixbuf/jxl.thumbnailer /usr/local/share/thumbnailers/jxl.thumbnailer
Update the Mime database with
update-mime --local
or
sudo update-desktop-database
Then possibly delete the thumbnail cache with
rm -r ~/.cache/thumbnails
and restart the application displaying thumbnails, e.g. `nautilus -q` to display thumbnails.
