27 !!DESCRIPTION
28
29
30 The ''starfish'' program draws radially symmetric
31 objects, which expand, contract, rotate, and turn inside
32 out. It uses these shapes to lay down a field of smooth
33 colors, and then rotates the colormap.
34 !!OPTIONS
35
36
37 ''starfish'' accepts the following options:
38
39
40 __-window__
41
42
43 Draw on a newly-created window. This is the
44 default.
45
46
47 __-root__
48
49
50 Draw on the root window.
51
52
53 __-mono__
54
55
56 If on a color display, pretend we're on a monochrome
57 display.
58
59
60 __-install__
61
62
63 Install a private colormap for the window.
64
65
66 __-visual__ ''visual''
67
68
69 Specify which visual to use. Legal values are the name of a
70 visual class, or the id number (decimal or hex) of a
71 specific visual.
72
73
74 __-delay__ ''microseconds''
75
76
77 How much of a delay should be introduced between steps of
78 the animation. Default 10000, or about 1/100th
79 second.
80
81
82 __-cycle-delay__ ''microseconds''
83
84
85 How long to wait between shifing the colormap by one step.
86 Default 100000, or about 1/10th second.
87
88
89 __-thickness__ ''pixels''
90
91
92 How wide each color band should be. Default 0, meaning
93 random (the chosen value will be between 0 and
94 15.)
95
96
97 __-rotation__ ''degrees''
98
99
100 How quickly the objects should rotate at each step. Default
101 0, meaning random (the chosen value will be between 0 and 12
102 degrees.)
103
104
105 __-colors__ ''int''
106
107
108 How many colors to use. Default 200. The more colors, the
109 smoother the transitions will be, and the nicer the
110 resultant images.
111
112
113 __-cycle__
114
115
116 __-no-cycle__
117
118
119 Whether to do colormap cycling. Default true.
120
121
122 __-duration__ ''seconds''
123
124
125 How long to run before choosing a new shape. Default 30
126 seconds.
127
128
129 __-delay2__ ''seconds''
130
131
132 When ''duration'' expires, how long to wait before
133 starting a new run. Default 5 seconds.
134
135
136 __-blob__
137
138
139 __-no-blob__
140
141
142 If ''blob'' option is specified, then the raw shapes will
143 be shown, instead of a field of colors generated from
144 them.
145 !!ENVIRONMENT
146
147
148 __DISPLAY__
149
150
151 to get the default host and display number.

153
154 __XENVIRONMENT__
155
156
157 to get the name of a resource file that overrides the global
158 resources stored in the RESOURCE_MANAGER
