SYNOPSIS

DESCRIPTION

The rotzoomer program grabs an image, then picks rectangles and draws
scaled and rotated animations of that section.

The image that it manipulates will be grabbed from the portion of the
screen underlying the window, or from the system's video input, or
from a random file on disk, as indicated by the grabDesktopImages,
grabVideoFrames, and chooseRandomImages options in the
~/.xscreensaver file; see xscreensaver-settings(1) for more details.
