DESCRIPTION

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.

OPTIONS

22       qix accepts the following options:
23
24       -window Draw on a newly-created window.  This is the default.
25
26       -root   Draw on the root window.
27
28       -mono   If on a color display, pretend we're on a monochrome display.
29
30       -install
31               Install a private colormap for the window.
32
33       -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
38       -segments integer
39               How many line segments should be drawn.  Default 50.
40
41       -spread integer
42               How far apart the endpoints of one segment should be  from  the
43               next.  Default 8.
44
45       -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
50       -count integer
51               How many qixes to draw.  Default 1.
52
53       -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
59       -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
63       -random The  qix  will wander around the screen semi-randomly.  This is
64               the default.
65
66       -linear The opposite of -random: the qix will travel in straight  lines
67               until it reaches a wall, and then it will bounce.
68
69       -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
74       -hollow The opposite of -solid; this is the default.
75
76       -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
81       -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
86       -non-transparent
87               Turns off -transparent.
88
89       -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
94       -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
99       -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
104       -gravity
105
106       -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
111       -fps    Display the current frame rate and CPU load.
112

ENVIRONMENT

114       DISPLAY to get the default host and display number.
115
116       XENVIRONMENT
117               to  get  the  name of a resource file that overrides the global
118               resources stored in the RESOURCE_MANAGER property.
