15 The distort program takes an image and lets circular zones of distor‐
16 tion wander randomly around it, distorting what is under them. The
17 mode of distortion and the overall behaviour of the zones can be influ‐
18 enced in various ways.
19 The image that it manipulates will be grabbed from the portion of the
21 screen underlying the window, or from the system's video input, or from
22 a random file on disk, as indicated by the grabDesktopImages, grabVide‐
23 oFrames, and chooseRandomImages options in the ~/.xscreensaver file;
24 see xscreensaver-demo(1) for more details.

27 distort accepts the following options:
28 -root Draw on the root window.
30 -window Draw on a newly-created window. This is the default.
32 -mono If on a color display, pretend we're on a monochrome display.
34 -install
36 Install a private colormap for the window.
37 -noinstall
39 Don't install a private colormap for the window.
40 -visual visual
42 Specify which visual to use. Legal values are the name of a
43 visual class or the id number (decimal or hex) of a specific
44 visual.
45 -window-id window-id
47 Specify which window id to use.
48 -delay usecs
50 Specify the delay between subsequent animation frames in
51 microseconds.
52 -radius pixels
54 Specify the radius of the distortion zone in pixels.
55 -speed int
57 Specify the speed at which the distortion zone moves, where 0
58 is slow, higher numbers are faster (10 is pretty fast.)
59 -number int
61 Specify the number of distortion zones.
62 -swamp Instead of letting zones wander around, let small zones pop up
64 like bubbles in a swamp and leave permanent distortion. WARN‐
65 ING: this option uses a colossal amount of memory: keep the
66 -radius small when using -swamp.
67 -bounce Let zones wander around and bounce off the window border. This
69 is the default.
70 -reflect
72 Mode of distortion that resembles reflection by a cylindrical
73 mirror.
74 -vortex Whirlpool-shaped distortion. Way cool.
76 -magnify
78 This mode of distortion looks like a magnifying glass.
79 -blackhole
81 Suck your pixels beyond the event horizon. Favourite mode of Dr
82 Stephen Hawking.
83 -slow Make the zone wander slower.
85 -shm Use shared memory extension.
87 -no-shm Don't use shared memory extension.
89
91 DISPLAY to get the default host and display number
92 XENVIRONMENT
94 to get the name of a resource file that overrides the global
95 resources stored in the RESOURCE_MANAGER property.
