|gdk-pixbuf-query-loaders [--update-cache] [MODULE...]|
gdk-pixbuf-query-loaders collects information about loadable modules for gdk-pixbuf and writes it to the default cache file location, or to stdout.
If called without arguments, it looks for modules in the gdk-pixbuf loader directory.
If called with arguments, it looks for the specified modules. The arguments may be absolute or relative paths.
