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 resources stored in the RESOURCE_MANAGER property.
