!!DESCRIPTION |

|
|
|
31 |
The ''qix'' program bounces a series of line segments |
|
|
32 |
around its window. This is truly the swiss army chainsaw of |
|
|
33 |
qix programs. If you know of one with more display modes, I |
|
|
34 |
want to know about it. |
|
|
35 |
!!OPTIONS |
|
|
36 |
|
|
|
37 |
|
|
|
38 |
''qix'' accepts the following options: |
|
|
39 |
|
|
|
40 |
|
|
|
41 |
__-window__ |
|
|
42 |
|
|
|
43 |
|
|
|
44 |
Draw on a newly-created window. This is the |
|
|
45 |
default. |
|
|
46 |
|
|
|
47 |
|
|
|
48 |
__-root__ |
|
|
49 |
|
|
|
50 |
|
|
|
51 |
Draw on the root window. |
|
|
52 |
|
|
|
53 |
|
|
|
54 |
__-mono__ |
|
|
55 |
|
|
|
56 |
|
|
|
57 |
If on a color display, pretend we're on a monochrome |
|
|
58 |
display. |
|
|
59 |
|
|
|
60 |
|
|
|
61 |
__-install__ |
|
|
62 |
|
|
|
63 |
|
|
|
64 |
Install a private colormap for the window. |
|
|
65 |
|
|
|
66 |
|
|
|
67 |
__-visual__ ''visual'' |
|
|
68 |
|
|
|
69 |
|
|
|
70 |
Specify which visual to use. Legal values are the name of a |
|
|
71 |
visual class, or the id number (decimal or hex) of a |
|
|
72 |
specific visual. |
|
|
73 |
|
|
|
74 |
|
|
|
75 |
__-segments__ ''integer'' |
|
|
76 |
|
|
|
77 |
|
|
|
78 |
How many line segments should be drawn. Default |
|
|
79 |
50. |
|
|
80 |
|
|
|
81 |
|
|
|
82 |
__-spread__ ''integer'' |
|
|
83 |
|
|
|
84 |
|
|
|
85 |
How far apart the endpoints of one segment should be from |
|
|
86 |
the next. Default 8. |
|
|
87 |
|
|
|
88 |
|
|
|
89 |
__-size__ ''integer'' |
|
|
90 |
|
|
|
91 |
|
|
|
92 |
The maximum distance one endpoint of a segment is allowed to |
|
|
93 |
be from the opposite end of that segment. Default 0, meaning |
|
|
94 |
unlimited. |
|
|
95 |
|
|
|
96 |
|
|
|
97 |
__-count__ ''integer'' |
|
|
98 |
|
|
|
99 |
|
|
|
100 |
How many qixes to draw. Default 1. |
|
|
101 |
|
|
|
102 |
|
|
|
103 |
__-color-shift__ ''degrees'' |
|
|
104 |
|
|
|
105 |
|
|
|
106 |
If on a color display, the color of the line segments will |
|
|
107 |
cycle through the spectrum. This specifies how far the hue |
|
|
108 |
of each segment should be from the next, in degrees on the |
|
|
109 |
HSV wheel. Default 3. |
|
|
110 |
|
|
|
111 |
|
|
|
112 |
__-delay__ ''microseconds'' |
|
|
113 |
|
|
|
114 |
|
|
|
115 |
How much of a delay should be introduced between steps of |
|
|
116 |
the animation. Default 25000, or about 0.025 |
|
|
117 |
seconds. |
|
|
118 |
|
|
|
119 |
|
|
|
120 |
__-random__ |
|
|
121 |
|
|
|
122 |
|
|
|
123 |
The ''qix'' will wander around the screen semi-randomly. |
|
|
124 |
This is the default. |
|
|
125 |
|
|
|
126 |
|
|
|
127 |
__-linear__ |
|
|
128 |
|
|
|
129 |
|
|
|
130 |
The opposite of ''-random'': the ''qix'' will travel |
|
|
131 |
in straight lines until it reaches a wall, and then it will |
|
|
132 |
bounce. |
|
|
133 |
|
|
|
134 |
|
|
|
135 |
__-solid__ |
|
|
136 |
|
|
|
137 |
|
|
|
138 |
If this is specified, then the area between the line |
|
|
139 |
segments will be filled in with the appropriate color, |
|
|
140 |
instead of the ''qix'' simply being composed of |
|
|
141 |
one-pixel-wide line segments. This option looks really good |
|
|
142 |
in color. |
|
|
143 |
|
|
|
144 |
|
|
|
145 |
__-hollow__ |
|
|
146 |
|
|
|
147 |
|
|
|
148 |
The opposite of ''-solid''; this is the |
|
|
149 |
default. |
|
|
150 |
|
|
|
151 |
|
|
|
152 |
__-xor__ |
|
|
153 |
|
|
|
154 |
|
|
|
155 |
If this is specified, then qix segments will be drawn and |
|
|
156 |
erased with xor, instead of being drawn in some color and |
|
|
157 |
erased in the background color. This implies ''-mono'', |
|
|
158 |
in that only two colors can be used. |
|
|
159 |
|
|
|
160 |
|
|
|
161 |
__-transparent__ |
|
|
162 |
|
|
|
163 |
|
|
|
164 |
If this is specified, and ''-count'' is greater than 1, |
|
|
165 |
then each qix will be drawn in one color, and when they |
|
|
166 |
overlap, the colors will be mixed. This looks best in |
|
|
167 |
conjuction with ''-solid''. |
|
|
168 |
|
|
|
169 |
|
|
|
170 |
__-non-transparent__ |
|
|
171 |
|
|
|
172 |
|
|
|
173 |
Turns off ''-transparent''. |
|
|
174 |
|
|
|
175 |
|
|
|
176 |
__-additive__ |
|
|
177 |
|
|
|
178 |
|
|
|
179 |
If ''-transparent'' is specified, then this option means |
|
|
180 |
that the colors will be mixed using an additive color model, |
|
|
181 |
as if the qixes were projected light. This is the |
|
|
182 |
default. |
|
|
183 |
|
|
|
184 |
|
|
|
185 |
__-subtractive__ |
|
|
186 |
|
|
|
187 |
|
|
|
188 |
If ''-transparent'' is specified, then this option means |
|
|
189 |
that the colors will be mixed using a subtractive color |
|
|
190 |
model, as if the qixes were translucent |
|
|
191 |
filters. |
|
|
192 |
|
|
|
193 |
|
|
|
194 |
__-poly__ ''int'' |
|
|
195 |
|
|
|
196 |
|
|
|
197 |
How many vertices each qix-line should have: the default is |
|
|
198 |
2, meaning the traditional qix line shape. Three will yield |
|
|
199 |
triangles, and so on. |
|
|
200 |
|
|
|
201 |
|
|
|
202 |
__-gravity__ |
|
|
203 |
|
|
|
204 |
|
|
|
205 |
__-no-gravity__ |
|
|
206 |
|
|
|
207 |
|
|
|
208 |
Whether there should be downward attraction. For example, |
|
|
209 |
the options __-gravity -linear__ will make everything |
|
|
210 |
move in nice smooth parabolas. Gravity is off by |
|
|
211 |
default. |

__XENVIRONMENT__ |
|

222 |
