[-visual visual] [-window-id window-id] [-delay usecs]

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.
OPTIONSdistort 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 pix
els.
-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.
-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_MAN
AGER property.
