distort(6) XScreenSaver manual distort(6) NAME distort - distort the content of the screen in interesting ways SYNOPSIS distort [--root] [--window-id number][--window] [--mono] [--install] [--noinstall] [--visual visual] [--window-id window-id] [--delay usecs] [--duration secs] [--radius pixels] [--speed int] [--number int] [--swamp] [--bounce] [--reflect] [--vortex] [--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-settings(1) for more details. OPTIONS distort accepts the following options: --root Draw on the root window. --window-id number Draw on the specified 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 vi- sual class or the id number (decimal or hex) of a specific vi- sual. --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. XSCREENSAVER_WINDOW The window ID to use with --root.
