NAME

       decayscreen - make a screen meltdown.


SYNOPSIS

       decayscreen [-display host:display.screen] [-window] [-root] [-mono]
       [-install] [-visual visual] [-delay usecs] [-duration secs] [-mode
       mode] [-fps]


DESCRIPTION

       The decayscreen program creates a melting effect by randomly shifting
       rectangles around the screen.

       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

       decayscreen accepts the following options:

       -window Draw on a newly-created window.  This is the default.

       -root   Draw on the root window.

       -mono   If on a color display, pretend we're on a monochrome display.

       -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
               Slow it down.

       -duration seconds
               How long to run before loading a new image.  Default 120
               seconds.

       -mode mode
               The direction in which the image should tend to slide.  Legal
               values are random (meaning pick one), up, left, right, down,
               upleft, downleft, upright, downright, shuffle (meaning prefer
               no particular direction), in (meaning move things toward the
               center), out (meaning move things away from the center), melt
               (meaning melt straight downward),  stretch (meaning stretch the
               screen downward), and fuzz (meaning go blurry instead of
               melty).

       -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
