[Bug 2042857] Re: Cannot handle HEIC images

2023-11-18 Thread Cepheid
I can confirm this bug on Lubuntu 23.10.
Previously, on Lubuntu 23.04, I could view HEIC images with all image viewers, 
using heif-gdk-pixbuf and libheif-examples.
Now, on Lubuntu 23.10, I cannot view HEIC images any more with the following 
image viewers:

NOT WORKING image viewers / graphics software:
gThumb
Geeqie
LXimage
GIMP

The only viewer that is working to view HEIC images now on my Lubuntu 23.10 
machine is:
Eye of Mate (EOM)

[Bug 2042857] Re: Cannot handle HEIC images

2023-11-18 Thread Cepheid
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
