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.
