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.

OPTIONS

       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.

ENVIRONMENT

       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.
