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

SYNOPSIS
       distort [-root] [-window] [-mono] [-install] [-noinstall] [-visual vis-
       ual] [-window-id	window-id] [-delay usecs]  [-duration  secs]  [-radius
       pixels] [-speed int] [-number int] [-swamp] [-bounce] [-reflect]	[-vor-
       tex] [-magnify] [-blackhole] [-slow] [-shm] [-no-shm] [-fps]

DESCRIPTION
       The distort program takes an image and lets circular zones  of  distor-
       tion  wander  randomly  around  it, distorting what is under them.  The
       mode of distortion and the overall behaviour of the zones can be	influ-
       enced 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, grabVide-
       oFrames,	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 mi-
	       croseconds.

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

       -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.	 WARN-
	       ING: 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.

       -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.
