At least on my computer, I think the source of the problem is not in GIMP, because it also effects other viewers and even imgmagick.
I have a bash script for mass conversion of jpg to heic. This shell script uses "heif-enc" and after the upgrade to Lubuntu 23.10, it's still working like before. However, when I want to use imgmagick to display the heic file, it's not working. display test.heic => nothing is happening. Imgmagick doesn't show the file. The same behaviour for gThumb, Geeqie, LXimage, GIMP Only Eye of Mate (EOM) succeeds in displaying the photo. I think the interesting question would be: How is EOM different to these other graphics programs? I suspect that EOM has built-in HEIC support while the others are using the generic library. I also suspect that somehow the HEIC file type is not properly registered any more after the upgrade to Lubuntu 23.10 -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gimp in Ubuntu. https://bugs.launchpad.net/bugs/2042857 Title: Cannot handle HEIC images To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gimp/+bug/2042857/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
