17 The qix program bounces a series of line segments around its window.
18 This is truly the swiss army chainsaw of qix programs. If you know of
19 one with more display modes, I want to know about it.
20
22 qix accepts the following options:
23 -window Draw on a newly-created window. This is the default.
25 -root Draw on the root window.
27 -mono If on a color display, pretend we're on a monochrome display.
29 -install
31 Install a private colormap for the window.
32 -visual visual
34 Specify which visual to use. Legal values are the name of a
35 visual class, or the id number (decimal or hex) of a specific
36 visual.
37 -segments integer
39 How many line segments should be drawn. Default 50.
40 -spread integer
42 How far apart the endpoints of one segment should be from the
43 next. Default 8.
44 -size integer
46 The maximum distance one endpoint of a segment is allowed to be
47 from the opposite end of that segment. Default 0, meaning
48 unlimited.
49 -count integer
51 How many qixes to draw. Default 1.
52 -color-shift degrees
54 If on a color display, the color of the line segments will
55 cycle through the spectrum. This specifies how far the hue of
56 each segment should be from the next, in degrees on the HSV
57 wheel. Default 3.
58 -delay microseconds
60 How much of a delay should be introduced between steps of the
61 animation. Default 10000, or about 0.01 seconds.
62 -random The qix will wander around the screen semi-randomly. This is
64 the default.
65 -linear The opposite of -random: the qix will travel in straight lines
67 until it reaches a wall, and then it will bounce.
68 -solid If this is specified, then the area between the line segments
70 will be filled in with the appropriate color, instead of the
71 qix simply being composed of one-pixel-wide line segments.
72 This option looks really good in color.
73 -hollow The opposite of -solid; this is the default.
75 -xor If this is specified, then qix segments will be drawn and
77 erased with xor, instead of being drawn in some color and
78 erased in the background color. This implies -mono, in that
79 only two colors can be used.
80 -transparent
82 If this is specified, and -count is greater than 1, then each
83 qix will be drawn in one color, and when they overlap, the col‐
84 ors will be mixed. This looks best in conjunction with -solid.
85 -non-transparent
87 Turns off -transparent.
88 -additive
90 If -transparent is specified, then this option means that the
91 colors will be mixed using an additive color model, as if the
92 qixes were projected light. This is the default.
93 -subtractive
95 If -transparent is specified, then this option means that the
96 colors will be mixed using a subtractive color model, as if the
97 qixes were translucent filters.
98 -poly int
100 How many vertices each qix-line should have: the default is 2,
101 meaning the traditional qix line shape. Three will yield tri‐
102 angles, and so on.
103 -gravity
105 -no-gravity
107 Whether there should be downward attraction. For example, the
108 options -gravity -linear will make everything move in nice
109 smooth parabolas. Gravity is off by default.
110 -fps Display the current frame rate and CPU load.
112
114 DISPLAY to get the default host and display number.
115 XENVIRONMENT
117 to get the name of a resource file that overrides the global
118 resources stored in the RESOURCE_MANAGER property.
