DESCRIPTION

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
20       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-settings(1) for more details.

OPTIONS

27       distort accepts the following options:
28
29       -root   Draw on the root window.
30
31       -window Draw on a newly-created window. This is the default.
32
33       -mono   If on a color display, pretend we're on a monochrome display.
34
35       -install
36               Install a private colormap for the window.
37
38       -noinstall
39               Don't install a private colormap for the window.
40
41       -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
46       -window-id window-id
47               Specify which window id to use.
48
49       -delay usecs
50               Specify  the  delay  between subsequent animation frames in mi‐
51               croseconds.
52
53       -duration seconds
54               How long to run before loading a new image.  Default  120  sec‐
55               onds.
56
57       -radius pixels
58               Specify the radius of the distortion zone in pixels.
59
60       -speed int
61               Specify  the  speed at which the distortion zone moves, where 0
62               is slow, higher numbers are faster (10 is pretty fast.)
63
64       -number int
65               Specify the number of distortion zones.
66
67       -swamp  Instead of letting zones wander around, let small zones pop  up
68               like  bubbles in a swamp and leave permanent distortion.  WARN‐
69               ING: this option uses a colossal amount  of  memory:  keep  the
70               -radius small when using -swamp.
71
72       -bounce Let  zones wander around and bounce off the window border. This
73               is the default.
74
75       -reflect
76               Mode of distortion that resembles reflection by  a  cylindrical
77               mirror.
78
79       -vortex Whirlpool-shaped distortion. Way cool.
80
81       -magnify
82               This mode of distortion looks like a magnifying glass.
83
84       -blackhole
85               Suck your pixels beyond the event horizon. Favourite mode of Dr
86               Stephen Hawking.
87
88       -slow   Make the zone wander slower.
89
90       -shm    Use shared memory extension.
91
92       -no-shm Don't use shared memory extension.
93
94       -fps    Display the current frame rate and CPU load.
