NAME
       distort - distort the content of the screen in interesting ways

SYNOPSIS
       distort	[-root]  [-window] [-mono] [-install] [-noinstall] [-visual visual] [-window-id window-id] [-delay usecs] [-radius pixels] [-speed
       int] [-number int] [-swamp] [-bounce] [-reflect] [-vortex] [-magnify] [-blackhole] [-slow] [-shm] [-no-shm]

DESCRIPTION
       The distort program takes an image and lets circular zones of distortion wander randomly around it, distorting what  is	under  them.   The
       mode of distortion and the overall behaviour of the zones can be influenced in various ways.

       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
       distort accepts the following options:

       -root   Draw on the root window.

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

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

       -install
	       Install a private colormap for the window.

       -noinstall
	       Don't 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.

       -window-id window-id
	       Specify which window id to use.

       -delay usecs
	       Specify the delay between subsequent animation frames in microseconds.

       -radius pixels
	       Specify the radius of the distortion zone in pixels.

       -speed int
	       Specify the speed at which the distortion zone moves, where 0 is slow, higher numbers are faster (10 is pretty fast.)

       -number int
	       Specify the number of distortion zones.

       -swamp  Instead	of  letting  zones wander around, let small zones pop up like bubbles in a swamp and leave permanent distortion.  WARNING:
	       this option uses a colossal amount of memory: keep the -radius small when using -swamp.

       -bounce Let zones wander around and bounce off the window border. This is the default.

       -reflect
	       Mode of distortion that resembles reflection by a cylindrical mirror.

       -vortex Whirlpool-shaped distortion. Way cool.

       -magnify
	       This mode of distortion looks like a magnifying glass.

       -blackhole
	       Suck your pixels beyond the event horizon. Favourite mode of Dr Stephen Hawking.

       -slow   Make the zone wander slower.

       -shm    Use shared memory extension.

       -no-shm Don't use shared memory extension.

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.
