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]  [-vis-
       ual visual]

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, grabVide-
       oFrames,  and  chooseRandomImages  options in the ~/.xscreensaver file;
       see xscreensaver-demo(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.

       -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.
