NAME
       rotzoomer - animated rotations and scalings of portions of
       the screen

SYNOPSIS
       rotzoomer   [-display   host:display.screen]   [-move    |
       -no-move]  [-delay  usecs]  [-n  count]  [-shm  | -no-shm]
       [-window] [-root] [-install] [-visual visual]

DESCRIPTION
       The rotzoomer program grabs an image, then  picks  rectan-
       gles  and draws scaled and rotated animations of that sec-
       tion.

       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(o) 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.

       -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 microseconds
               How much of a delay should be  introduced  between
               steps  of  the animation.  Default 10000, or about
               1/100th second.

       -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  simultaniously.
               Default 2.

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

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.
