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.
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 a private colormap for the window.
Don't install a private colormap for the window.
Specify which visual to use. Legal values are the name of a
visual class or the id number (decimal or hex) of a specific
Specify which window id to use.
Specify the delay between subsequent animation frames in
Specify the radius of the distortion zone in pixels.
Specify the speed at which the distortion zone moves, where 0
is slow, higher numbers are faster (10 is pretty fast.)
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.
Mode of distortion that resembles reflection by a cylindrical
-vortex Whirlpool-shaped distortion. Way cool.
This mode of distortion looks like a magnifying glass.
Suck your pixels beyond the event horizon. Favourite mode of Dr
-slow Make the zone wander slower.
-shm Use shared memory extension.
-no-shm Don't use shared memory extension.
DISPLAY to get the default host and display number
to get the name of a resource file that overrides the global
resources stored in the RESOURCE_MANAGER property.
