HEIC/HEIF files don't show up on the file browser on ART 1.26.7 flatpak

[night199uk]

Hi,

I am running ART 1.26.7 from Flathub on Fedora Silverblue 43.

I have added heic/heif/hif to the "parsed extensions" list in Preferences->File Browser.

I have installed the ART-imageio files to ~/.var/app/us.pixls.art.ART/config/ART/imageio

I have followed all of the feedback in #347 and can manually run:
python3 hif/heif_io.py input.heic output.tif

... from within the Flatpak using:
flatpak run --devel --command=bash us.pixls.art.ART

All of these steps work fine. Yet I still don't see HEIC/HEIF files showing up in the file browser.

how can I further debug this issue please? ART doesn't seem to log anything and doesn't even seem to try and open the heic/heif files as far as I can see.

Hi,
I'm sorry but I don't maintain the Flatpak and I have no experience with that technology. Did you try using the appimage? If that works, maybe it's an issue with the default permissions -- other than that, I wouldn't know...

thanks for the response. is there any way to turn on debug or tracing for image loading in ART so that i can debug myself?

You can increase the verbosity level in the options file and see if you notice anything strange.

i ended up strace'ing the binary. the flatpak uses pillow_heif 0.22.0 which has various deprecations, mostly the ones in #347 but some others. i raised artraweditor/ART-imageio#2 which fixes ART-imageio for pillow_heif 0.22.0 and also later versions (up to 1.5.0).
