fastiv
======
'fastiv' is a fast image viewer, supporting BMP, PNG, GIF, JPEG, and optionally
raw photos, HEIC, AVIF, WebP, SVG, X11 cursors and TIFF, or whatever gdk-pixbuf
loads.
'fastiv' is a fast image viewer, directly supporting BMP, PNG, GIF, JPEG, WebP,
and optionally raw photos, HEIC, AVIF, SVG, X11 cursors and TIFF,
or whatever gdk-pixbuf loads.
Its development status can be summarized as '`beta`'.
E.g., certain GIFs animate wrong.
