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