Pinta can open but can't save as JPEG XL (.jxl)

[david2000hun1]

Description
I can open .jxl files however I can't save anything as .jxl.

To Reproduce

1. Open any file
2. Save as .jxl

Additional Info

GLib.GException: Error when getting information for file “/home/david/Pictures/IMG-20250223-WA00022.jxl”: No such file or directory

This issue seems to be similar to #1857

Version
Cachyos x86_64
Pinta 3.2
I installed Pinta from the AUR.

Can you let us know if libjxl is installed and try installing it if not?

I'm wondering if Glycin might be providing import but not export capabilities.

[david2000hun1]

Yes, libjxl is installed. I have no idea if it's a problem with Glycin or not.

[david2000hun1]

To see if it was an issue with the AUR package, I built Pinta from scratch and the issue still remains. The error is the exact same. Running pinta --debug from the terminal shows nothing other than that error.

This looks like a similar stack trace to #2176

[cameronwhite]

Bug #2176 is fixed, so I suspect you would now see a proper error message saying that the file format cannot be exported?

https://gnome.pages.gitlab.gnome.org/glycin/#supported-image-formats claims that glycin does support exporting jxl, though ..

What is the output from gdk-pixbuf-query-loaders?

A few days ago I also tried to save something as .gif which also gave a similar error. So now I tried a lot more image formats which should be supported by glycin, and here are the ones that give errors:

.apng, .exr, .jp2:

[cameronwhite]

Interesting, "jxl" 5 "gdk-pixbuf" "JPEG XL image" "BSD-3" indicates that it should support writing
That's the same as .webp below - do you have the same issue with that format?

The second stack trace there should be fixed by the most recent commit, so if it's possible to build from git you could try that out.
For the first stack trace, I'm not quite sure how it would get into that state - are you saving a file without an extension by chance?

[david2000hun1]

I just checked and no issues with .webp. For the first stack trace, no, I tried saving it with the extension. I will try building from git then.

[david2000hun1]

I've built Pinta and the second stack trace is fixed. I only get a message saying Pinta doesn't support saving images in that format. I still have the same issues with the other formats.
