Latest update: I got the rendering of AVIF files working with
GraphicsMagick:
* Made sure that GraphicsMagick properly reports its list of supported
file formats. By doing so I found what I believe to be a [bug in
Arch][1].
* Explicitly specified GraphicsMagick as converter, although according
to documentation it should be chosen automatically if not set:
'(image-converter 'graphicsmagick)
* As before, I specified `avif` as an extension of files to render in
`image-mode` upon loading:
'(image-file-name-extensions
'("png" "jpeg" "jpg" "gif" "tiff" "tif" "xbm" "xpm" "pbm"
"pgm" "ppm" "pnm" "svg" "avif"))
However, that does *not* work. AVIF files are opened in
`fundamental-mode`, and I have to do:
M-x image-mode
Now, I would like to try if setting `image-file-name-regexps` can solve
the issue. However, when I add a regular expression such as simply the
four characters “avif”, then customize reports an error message:
image-file-name-regexp: Wrong type argument: characterp, "avif"
*Why is that? How do I properly specify a regular expression here?*
See full configuration attached.
(About raw files: GraphicsMagick does support ARW files, albeit
rendering is slow. Via so called delegates it can be extended to
support additional file formats, and maybe I can tell it to use the
preview embedded in an ARW in order to speed things up.)
