Name
distort - distort the content of the screen in interesting waysSynopsis
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 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.
