I have Gimp 2.10.22 running, which should have HEIC support according to the release notes from last October. So I would have expected that an iOS-created .heic file should open up. Unfortunately, I just get the generic "Unknown file type" error from Gimp when I try to open it there, or drag and drop into Gimp.
The release notes, as well as all the various third party announcements I've seen about the heic support fail to give an example of how to import/open the file.
So I'm stuck - how can I get Gimp to load a .heic image that was created by iOS?
Thanks.
