Current evaluation

Feature request to automate gdk-pixbuf loader integration in snaps. Now implemented via desktop extensions: desktop-exports sets GDK_PIXBUF_MODULE_FILE/MODULEDIR and regenerates the cache. 0 comments, no maintainer activity in ~9 years.

Suggested action: close stale

Reason: The requested automation is implemented in current code: extensions/desktop/common/desktop-exports exports GDK_PIXBUF_MODULE_FILE/GDK_PIXBUF_MODULEDIR and regenerates the loaders cache via gdk-pixbuf-query-loaders, and snapcraft/extensions/gnome.py sets GDK_PIXBUF_MODULE_FILE to the SDK loaders.cache. With the feature delivered via desktop extensions, the 10-year-old request is no longer applicable, so it can be closed as implemented rather than kept open.

Impact: 20 Quick Win: 12.0 Staleness: 95 Complexity: 40 Confidence: 85 Support Request: 10

Issue body

gtk softwares need gdkpixbuf image loaders to be able to display images (jpg, png, svg, ...) if you want that to work you need to - include the loaders - generate a cache (or ship a static one in the source and copy it) - include mimetype definition (or a static mime.cache) so the loader knows what image type is needed - set those environment variable "# Gdk-pixbuf loaders export GDK_PIXBUF_MODULE_FILE=$SNAP/usr/lib/$ARCH/gdk-pixbuf-2.0/2.10.0/loaders.cache export GDK_PIXBUF_MODULEDIR=$SNAP/usr/lib/$ARCH/gdk-pixbuf-2.0/2.10.0" ideally snapcraft would do that for you
