NAME

       rotzoomer - animated rotations and scalings of portions of the screen

SYNOPSIS

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

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 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.

       -no-move
               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.

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.
