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.
rotzoomer accepts the following options:
--window
Draw on a newly-created window. This is the default.
--root
Draw on the root window.
--window-id number
Draw on the specified window.
--install
Install a private colormap for the window.
--visual visual
Specify which visual to use. Legal values are the name of a visual class, or the id number (decimal or hex) of a specific visual.
--delay milliseconds
How much of a delay should be introduced between steps of the animation. Default 10, or about 1/100th second.
--duration seconds
How long to run before loading a new image. Default 120 seconds.
--move
Make the rectangles should wander around the screen.
--no-move
Make the rectangles be stationary. This is the default.
--n count
How many rectangles to animate simultaneously. Default 2.
--no-shm
Disable use of the SHM extension, even if it appears to be available.
--fps
Display the current frame rate and CPU load.
DISPLAY
to get the default host and display number.
XENVIRONMENT
to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property.
XSCREENSAVER_WINDOW
The window ID to use with --root.
