NAME

6       ifs - draws spinning, colliding iterated-function-system images
7

SYNOPSIS

9       ifs  [-display  host:display.screen] [-visual visual] [-window] [-root]
10       [-no-db] [-delay number] [-detail number] [-colors number]  [-functions
11       number]  [-iterate | -recurse] [-no-rotate] [-no-scale] [-no-translate]
12       [-fps]

DESCRIPTION

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

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 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  ap‐
39               ply functions (recursion depth) before drawing each point.  De‐
40               fault: 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 or‐
47               der, 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

ENVIRONMENT

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.
