13
15 The ifs program draws spinning, colliding iterated-function-system
16 images.
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 Draw on a newly-created window. This is the default.
25
26 -root Draw on the root window.
27
28 -no-db Disable double-buffering.
29
30 -delay number
31 Per-frame delay, in microseconds. Default: 20000
32
33 -colors number
34 Number of colours to use. Default: 200
35
36 -detail number
37 In -iterate mode, number of times to randomly iterate the func‐
38 tions, in thousands. In -recurse mode, number of times to
39 apply functions (recursion depth) before drawing each point.
40 Default: 9
41
42 -functions number
43 Number of functions to be iterated. Default: 3
44
45 -iterate
46 Calculate by iteratively applying the functions in a random
47 order, usually faster than -recurse. This is the default.
48
49 -recurse
50 Calculate by recursively applying all combinations of the func‐
51 tions. This is the historical behavior and may produce neater
52 output than -iterate.
53
54 -no-rotate
55 Disable the rotation component of the functions.
56
57 -no-scale
58 Disable the scaling component of the functions.
59
60 -no-translate
61 Disable the varying translation component of the functions.
62
63 -no-multi
64 Turn off multi-coloured mode, only one colour is used to colour
65 the whole set.
66
67 -fps Display the current frame rate and CPU load.
68
70 DISPLAY to get the default host and display number.
71
72 XENVIRONMENT
73 to get the name of a resource file that overrides the global
74 resources stored in the RESOURCE_MANAGER property.
