XScreenSaver !!!XScreenSaver NAME SYNOPSIS DESCRIPTION OPTIONS ENVIRONMENT SEE ALSO COPYRIGHT AUTHORS ---- !!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. __-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. !!SEE ALSO X(1), xscreensaver(1), xscreensaver-demo(1), xscreensaver-getimage(1) !!COPYRIGHT Copyright 1998 by Jonas Munsin and Jamie Zawinski.
