18 The qix program bounces a series of line segments around its window.
19 This is truly the swiss army chainsaw of qix programs. If you know of
20 one with more display modes, I want to know about it.
21
23 qix accepts the following options:
24 --window
26 Draw on a newly-created window. This is the default.
27 --root Draw on the root window.
29 --window-id number
31 Draw on the specified window.
32 --mono If on a color display, pretend we're on a monochrome display.
34 --install
36 Install a private colormap for the window.
37 --visual visual
39 Specify which visual to use. Legal values are the name of a
40 visual class, or the id number (decimal or hex) of a specific
41 visual.
42 --segments integer
44 How many line segments should be drawn. Default 50.
45 --spread integer
47 How far apart the endpoints of one segment should be from the
48 next. Default 8.
49 --size integer
51 The maximum distance one endpoint of a segment is allowed to be
52 from the opposite end of that segment. Default 0, meaning un‐
53 limited.
54 --count integer
56 How many qixes to draw. Default 1.
57 --color-shift degrees
59 If on a color display, the color of the line segments will cy‐
60 cle through the spectrum. This specifies how far the hue of
61 each segment should be from the next, in degrees on the HSV
62 wheel. Default 3.
63 --delay microseconds
65 How much of a delay should be introduced between steps of the
66 animation. Default 10000, or about 0.01 seconds.
67 --random
69 The qix will wander around the screen semi-randomly. This is
70 the default.
71 --linear
73 The opposite of --random: the qix will travel in straight lines
74 until it reaches a wall, and then it will bounce.
75 --solid If this is specified, then the area between the line segments
77 will be filled in with the appropriate color, instead of the
78 qix simply being composed of one-pixel-wide line segments.
79 This option looks really good in color.
80 --hollow
82 The opposite of --solid; this is the default.
83 --xor If this is specified, then qix segments will be drawn and
85 erased with xor, instead of being drawn in some color and
86 erased in the background color. This implies --mono, in that
87 only two colors can be used.
88 --transparent
90 If this is specified, and --count is greater than 1, then each
91 qix will be drawn in one color, and when they overlap, the col‐
92 ors will be mixed. This looks best in conjunction with
93 --solid.
94 --non-transparent
96 Turns off --transparent.
97 --additive
99 If --transparent is specified, then this option means that the
100 colors will be mixed using an additive color model, as if the
101 qixes were projected light. This is the default.
102 --subtractive
104 If --transparent is specified, then this option means that the
105 colors will be mixed using a subtractive color model, as if the
106 qixes were translucent filters.
107 --poly int
109 How many vertices each qix-line should have: the default is 2,
110 meaning the traditional qix line shape. Three will yield tri‐
111 angles, and so on.
112 --gravity
114 --no-gravity
116 Whether there should be downward attraction. For example, the
117 options --gravity --linear will make everything move in nice
118 smooth parabolas. Gravity is off by default.
119 --fps Display the current frame rate and CPU load.
121
123 DISPLAY to get the default host and display number.
124 XENVIRONMENT
126 to get the name of a resource file that overrides the global
127 resources stored in the RESOURCE_MANAGER property.
128 XSCREENSAVER_WINDOW
130 The window ID to use with --root.
