       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.

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.

rotzoomer accepts the following options:

       --window
               Draw on a newly-created window.  This is the default.

       --root  Draw on the root window.

       --window-idnumber
               Draw on the specified window.

       --install
               Install a private colormap for the window.

       --visualvisual
               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.

       --delaymilliseconds
               How  much  of  a delay should be introduced between steps of the animation.  Default 10, or about
               1/100th second.

       --durationseconds
               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.

       --ncount
               How many rectangles to animate simultaneously.  Default 2.

       --no-shm
               Disable use of the SHM extension, even if it appears to be available.
