Recognize images based on content not name
Please describe the problem you are trying to solve
…
shotwell ~/.face
does return a format ignored whereas it's a perfectly valid PNG file. Copied to/tmp/face.png
, the file can be opened by shotwell without issue, which tells me that shotwell does the check based on name and not content.
Other solutions you have considered
…
gimp ~/.face
works without problem (but takes longer to start, just to view an image).
$ file ~/.face
.face: PNG image data, 512 x 512, 8-bit/color RGBA, non-interlaced
