Info

imgscreensaver is a tiny screensaver utility which displays an image in the
center of the screen. It has been developed for X.org X11 on Linux but should
also work in other Unix/X11 environments.

It is designed to sleep as much as possible, and works well with large
timeouts. Other screensaver apps tend to poll once per second.

Requirements:
	X11 with screensaver extension
	ImageMagick with MagickWand

Usage: imgscreensaver -t 60 -i foo.jpg
(for a 60 second idle timeout and the foo.jpg image)

Bugs and TODO:
 - We have to usleep(10000) after we enable the screensaver, otherwise
   sometimes the screen goes blank without displaying the image. This is
   particularly common when running compiz and the screen fades to black.
 - When running the screensaver under a window manager like GNOME's metacity,
   the screensaver appears in a desktop-managed window rather than drawing
   over the X root window. rsaver and beforelight have the same bug.
