       rotzoomer - animated rotations and scalings of portions of the screen


       rotzoomer  [-display  host:display.screen]  [-move  | -no-move] [-delay
       millisecs] [-duration secs]  [-n  count]  [-shm  |  -no-shm]  [-window]
       [-root] [-install] [-visual visual] [-fps]


       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-demo(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.

               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

       -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

       -move   Make the rectangles should wander around the screen.

               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

       -fps    Display the current frame rate and CPU load.


       DISPLAY to get the default host and display number.

               to  get  the  name of a resource file that overrides the global
               resources stored in the RESOURCE_MANAGER property.
