Using 24.08.3 on Gentoo Linux (and also previous versions, I think this happened somewhere in the KF6 transition), Gwenview can't save rotated JPEG images anymore. Steps to reproduce: - Open some JPEG image - Show Editing Tools - Rotate Right -Save An error message saying "Gwenview cannot save images in 'jfif' format." pops up. The processed image is not "jfif", but a good ole JPEG file. Happens with all of my photos I would like to rotate. My current workaround is to use jpegtran on the console, but this sucks ;-)
Hi - could you please check in your System Settings > Default Applications > File Associations, search for jpeg above the Known Types section, and then check the Filename Patterns on the right (potentially across each of the Known Types) to see if *.jfif is listed there? I'm wondering if this is another manifestation of https://bugs.kde.org/show_bug.cgi?id=433176 , which is ultimately the same root issue as https://bugs.kde.org/show_bug.cgi?id=439519 . It would also be worth double-checking to see if this exists in the latest version, which would be available via Flatpak if it's not yet distributed by Gentoo, as I can't personally reproduce the issue by following those steps on Gwenview 24.12.0, Fedora KDE 41. Thanks!
image/jpeg lists *.jfif, *.jpe, *.jpeg and *.jpg. I just tried it with 24.12.0, and I can confirm it does not happen with that version.
Glad it's working there, then! I'm checking on that other bug report to see if others with similar issues also have them resolved using that version. Thanks for checking!
