       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 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.

               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.

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