Luxor is a minimal image viewer for X. It supports vector graphics, animation and multi page images.
It depends on libextractor for identifying images, abydos for loading them and libX11 for displaying them.

The keys are read both from the X window and from stdin, which means the commands can be piped to Luxor.
