DESCRIPTION

15       The ifs program draws spinning, colliding iterated-function-system  im‐
16       ages.
17

OPTIONS

19       --visual visual
20               Specify  which  visual  to use.  Legal values are the name of a
21               visual class, or the id number (decimal or hex) of  a  specific
22               visual.
23
24       --window
25               Draw on a newly-created window.  This is the default.
26
27       --root  Draw on the root window.
28
29       --window-id number
30               Draw on the specified window.
31
32       --no-db Disable double-buffering.
33
34       --delay number
35               Per-frame delay, in microseconds.  Default: 20000
36
37       --colors number
38               Number of colours to use. Default: 200
39
40       --detail number
41               In  --iterate  mode,  number  of  times to randomly iterate the
42               functions, in thousands.  In --recurse mode, number of times to
43               apply  functions  (recursion  depth) before drawing each point.
44               Default: 9
45
46       --functions number
47               Number of functions to be iterated. Default: 3
48
49       --iterate
50               Calculate by iteratively applying the functions in a random or‐
51               der, usually faster than --recurse.  This is the default.
52
53       --recurse
54               Calculate by recursively applying all combinations of the func‐
55               tions.  This is the historical behavior and may produce  neater
56               output than --iterate.
57
58       --no-rotate
59               Disable the rotation component of the functions.
60
61       --no-scale
62               Disable the scaling component of the functions.
63
64       --no-translate
65               Disable the varying translation component of the functions.
66
67       --no-multi
68               Turn off multi-coloured mode, only one colour is used to colour
69               the whole set.
70
71       --fps   Display the current frame rate and CPU load.
72

ENVIRONMENT

74       DISPLAY to get the default host and display number.
75
76       XENVIRONMENT
77               to get the name of a resource file that  overrides  the  global
78               resources stored in the RESOURCE_MANAGER property.
79
80       XSCREENSAVER_WINDOW
81               The window ID to use with --root.
