xscreensaver-getimage - put some randomly-selected image on the root
xscreensaver-getimage [-display host:display.screen] [--verbose]
The xscreensaver-getimage program is a helper program for the
xscreensaver hacks that manipulate images. This is not a user-level
This program selects a random image, and puts it on the specified
window or pixmap. This image might be a snapshot of the desktop; or a
frame captured from the system's video input; or a randomly-selected
image from disk.
If only a window ID is specified, the image will be painted there. If
both a window ID and a pixmap ID are specified, then the image will be
painted on the pixmap; and the window may be modified as a side-effect.

random image from that feed will be selected instead. The contents
of the feed will be cached locally and refreshed periodically as
If none of the three options are set to True, then video colorbars will
be displayed instead.
When grabbing desktop images, the window argument will be unmapped and
have its contents modified, causing flicker. (This does not happen
when loading image files or video frames.)
