16 The distort program takes an image and lets circular zones of distor‐
17 tion wander randomly around it, distorting what is under them. The
18 mode of distortion and the overall behaviour of the zones can be influ‐
19 enced in various ways.
20
21 The image that it manipulates will be grabbed from the portion of the
22 screen underlying the window, or from the system's video input, or from
23 a random file on disk, as indicated by the grabDesktopImages, grabVide‐
24 oFrames, and chooseRandomImages options in the ~/.xscreensaver file;
25 see xscreensaver-settings(1) for more details.
26
28 distort accepts the following options:
29
30 --root Draw on the root window.
31
32 --window-id number
33 Draw on the specified window.
34
35 --window
36 Draw on a newly-created window. This is the default.
37
38 --mono If on a color display, pretend we're on a monochrome display.
39
40 --install
41 Install a private colormap for the window.
42
43 --noinstall
44 Don't install a private colormap for the window.
45
46 --visual visual
47 Specify which visual to use. Legal values are the name of a
48 visual class or the id number (decimal or hex) of a specific
49 visual.
50
51 --window-id window-id
52 Specify which window id to use.
53
54 --delay usecs
55 Specify the delay between subsequent animation frames in mi‐
56 croseconds.
57
58 --duration seconds
59 How long to run before loading a new image. Default 120 sec‐
60 onds.
61
62 --radius pixels
63 Specify the radius of the distortion zone in pixels.
64
65 --speed int
66 Specify the speed at which the distortion zone moves, where 0
67 is slow, higher numbers are faster (10 is pretty fast.)
68
69 --number int
70 Specify the number of distortion zones.
71
72 --swamp Instead of letting zones wander around, let small zones pop up
73 like bubbles in a swamp and leave permanent distortion. WARN‐
74 ING: this option uses a colossal amount of memory: keep the
75 --radius small when using --swamp.
76
77 --bounce
78 Let zones wander around and bounce off the window border. This
79 is the default.
80
81 --reflect
82 Mode of distortion that resembles reflection by a cylindrical
83 mirror.
84
85 --vortex
86 Whirlpool-shaped distortion. Way cool.
87
88 --magnify
89 This mode of distortion looks like a magnifying glass.
90
91 --blackhole
92 Suck your pixels beyond the event horizon. Favourite mode of Dr
93 Stephen Hawking.
94
95 --slow Make the zone wander slower.
96
97 --shm Use shared memory extension.
98
99 --no-shm
100 Don't use shared memory extension.
101
102 --fps Display the current frame rate and CPU load.
103
105 DISPLAY to get the default host and display number
106
107 XENVIRONMENT
108 to get the name of a resource file that overrides the global
109 resources stored in the RESOURCE_MANAGER property.
110
111 XSCREENSAVER_WINDOW
112 The window ID to use with --root.
