6 [\-root] [\-window] [\-mono] [\-install] [\-noinstall] [\-visual \fIvisual\fP]

22 The \fIdistort\fP program takes an image and lets circular zones of
23 distortion wander randomly around it, distorting what is under them.
24 The mode of distortion and the overall behaviour of the zones can be
25 influenced in various ways.
27 The image that it manipulates will be grabbed from the portion of
28 the screen underlying the window, or from the system's video input,
29 or from a random file on disk, as indicated by
30 the \fIgrabDesktopImages\fP, \fIgrabVideoFrames\fP,
31 and \fIchooseRandomImages\fP options in the \fI~/.xscreensaver\fP
33 .BR xscreensaver-demo (1)
37 accepts the following options:
40 Draw on the root window.
43 Draw on a newly-created window. This is the default.
46 If on a color display, pretend we're on a monochrome display.
49 Install a private colormap for the window.
52 Don't install a private colormap for the window.
54 .B \-visual \fIvisual\fP
55 Specify which visual to use. Legal values are the name of a visual
56 class or the id number (decimal or hex) of a specific visual.
58 .B \-window\-id \fIwindow\-id\fP
59 Specify which window id to use.
61 .B \-delay \fIusecs\fP
62 Specify the delay between subsequent animation frames in microseconds.
64 .B \-duration \fIseconds\fP
65 How long to run before loading a new image. Default 120 seconds.
67 .B \-radius \fIpixels\fP
68 Specify the radius of the distortion zone in pixels.
71 Specify the speed at which the distortion zone moves, where 0 is slow,
72 higher numbers are faster (10 is pretty fast.)
75 Specify the number of distortion zones.
78 Instead of letting zones wander around, let small zones pop up like
79 bubbles in a swamp and leave permanent distortion. \fBWARNING:\fP
80 this option uses a \fIcolossal\fP amount of memory: keep the \fI\-radius\fP
81 small when using \fI\-swamp\fP.
84 Let zones wander around and bounce off the window border. This is the
88 Mode of distortion that resembles reflection by a cylindrical mirror.
91 Whirlpool-shaped distortion. Way cool.
94 This mode of distortion looks like a magnifying glass.
97 Suck your pixels beyond the event horizon. Favourite mode of Dr
101 Make the zone wander slower.
104 Use shared memory extension.
107 Don't use shared memory extension.
112 to get the default host and display number
115 to get the name of a resource file that overrides the global resources
116 stored in the RESOURCE_MANAGER property.
