NAME
     decayscreen - make a screen meltdown.

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

DESCRIPTION
     The  decayscreen program creates a melting effect by randomly shifting rec-
     tangles 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,  grabVide-
     oFrames,  and  chooseRandomImages	options in the ~/.xscreensaver file; see
     xscreensaver-settings(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.

     --window-id number
	     Draw on the specified 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  val-
	     ues  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  (mean-
	     ing  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  re-
	     sources stored in the RESOURCE_MANAGER property.

     XSCREENSAVER_WINDOW
	     The window ID to use with --root.
