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, grabVideoFrames, 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.
