        distort - distort the content of the screen in interesting ways


        distort  [-root]  [-window]  [-mono]  [-install]  [-noinstall] [-visual
        visual] [-window-id window-id] [-delay usecs] [-duration secs] [-radius
        pixels] [-speed int] [-number int] [-swamp] [-bounce] [-reflect] [-vor-
        tex] [-magnify] [-blackhole] [-slow] [-shm] [-no-shm] [-fps]


        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.
        -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
        -window-id window-id
                Specify which window id to use.
        -delay usecs
                Specify  the  delay  between  subsequent  animation  frames  in
        -duration seconds
                How long to run before loading a new image.  Default  120  sec-
        -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.
                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
                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.

                resources stored in the RESOURCE_MANAGER property.
