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

23 The \fIdistort\fP program takes an image and lets circular zones of
24 distortion wander randomly around it, distorting what is under them.
25 The mode of distortion and the overall behaviour of the zones can be
26 influenced in various ways.
28 The image that it manipulates will be grabbed from the portion of
29 the screen underlying the window, or from the system's video input,
30 or from a random file on disk, as indicated by
31 the \fIgrabDesktopImages\fP, \fIgrabVideoFrames\fP,
32 and \fIchooseRandomImages\fP options in the \fI~/.xscreensaver\fP
34 .BR xscreensaver-demo (1)
38 accepts the following options:
41 Draw on the root window.
44 Draw on a newly-created window. This is the default.
47 If on a color display, pretend we're on a monochrome display.
50 Install a private colormap for the window.
53 Don't install a private colormap for the window.
55 .B \-visual \fIvisual\fP
56 Specify which visual to use. Legal values are the name of a visual
57 class or the id number (decimal or hex) of a specific visual.
59 .B \-window\-id \fIwindow\-id\fP
60 Specify which window id to use.
62 .B \-delay \fIusecs\fP
63 Specify the delay between subsequent animation frames in microseconds.
65 .B \-duration \fIseconds\fP
66 How long to run before loading a new image. Default 120 seconds.
68 .B \-radius \fIpixels\fP
69 Specify the radius of the distortion zone in pixels.
72 Specify the speed at which the distortion zone moves, where 0 is slow,
73 higher numbers are faster (10 is pretty fast.)
76 Specify the number of distortion zones.
79 Instead of letting zones wander around, let small zones pop up like
80 bubbles in a swamp and leave permanent distortion. \fBWARNING:\fP
81 this option uses a \fIcolossal\fP amount of memory: keep the \fI\-radius\fP
82 small when using \fI\-swamp\fP.
85 Let zones wander around and bounce off the window border. This is the
89 Mode of distortion that resembles reflection by a cylindrical mirror.
92 Whirlpool-shaped distortion. Way cool.
95 This mode of distortion looks like a magnifying glass.
98 Suck your pixels beyond the event horizon. Favourite mode of Dr
102 Make the zone wander slower.
105 Use shared memory extension.
108 Don't use shared memory extension.
111 Display the current frame rate and CPU load.
116 to get the default host and display number
119 to get the name of a resource file that overrides the global resources
120 stored in the RESOURCE_MANAGER property.
