In order to activate thumbnails, it is necessary to update /usr/share/kservices5/imagethumbnail.desktop
and the image/jxl
mimetype (image-jxl.xml) should be installed.
In order to troubleshot I recommend to start gwenview
from konsole to see various debug/error messages:
gwenview testimage.jxl
Jxl animations are known not to work now because of https://gitlab.com/wg1/jpeg-xl/-/issues/87
I also use the opt
parameter to configure libjxl to see libjxl's internal error messages.
BUILD_DIR=/tmp/build ./ci.sh opt
Excuse me for newby mistakes) This issue, not sure how to how to interpret it
Out of all steps only
image/jxl mimetype (image-jxl.xml) should be installed.
is not done, don't know how to do that.
Added file association in settings manually
Console
> gwenview output.jxl
Icon theme "gnome" not found.
org.kde.kdegraphics.gwenview.lib: Unresolved mime type "image/x-mng"
org.kde.kdegraphics.gwenview.lib: Unresolved raw mime type "image/x-nikon-nrw"
org.kde.kdegraphics.gwenview.lib: Unresolved raw mime type "image/x-samsung-srw"
Gwenview gui show this error
My imagethumbnail.desktop thumbnails.zip
and here file itself file.zip
Copy image-jxl.xml
into the folder
/usr/share/mime/packages
I use slightly modified version ( https://gitlab.com/wg1/jpeg-xl/-/issues/81 ):
<?xml version="1.0" encoding="UTF-8"?>
<mime-info xmlns="http://www.freedesktop.org/standards/shared-mime-info">

I think you made a mistake because you registered image/jpegxl and I believe it should be image/jxl
Run update-mime-database /usr/share/mime
and try again:

Still doesn't work.
same console errors
I get same message when my plugin is missing or could not be loaded.
I have libqjpegxl.so in /usr/lib64/qt5/plugins/imageformats
folder. On some systems it could be /usr/lib/qt/plugins/imageformats/
or /usr/lib/x86_64-linux-gnu/qt5/plugins/imageformats
If it is there, try to go to the folder and check ldd libqjpegxl.so
if all required libraries are present.
libjxl.so.0 => not found libjxl_threads.so.0 => not found
for /usr/lib/qt/plugins/imageformats/libqjpegxl.so
libjpegxl installed

OK, you found the problem!
I have them installed in /usr/lib64
Try to copy or symlink it there (or maybe /usr/lib
on some systems) so the libjxl and libjxl_threads will be found easily.
Yep, it works now))
I figured out how to make it and install plugin. JPEG XL thumbnails don't show up and image viewers don't recognize it, please help)
