DESCRIPTION

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

OPTIONS

23       qix accepts the following options:
24
25       --window
26               Draw on a newly-created window.  This is the default.
27
28       --root  Draw on the root window.
29
30       --window-id number
31               Draw on the specified window.
32
33       --mono  If on a color display, pretend we're on a monochrome display.
34
35       --install
36               Install a private colormap for the window.
37
38       --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
43       --segments integer
44               How many line segments should be drawn.  Default 50.
45
46       --spread integer
47               How  far  apart the endpoints of one segment should be from the
48               next.  Default 8.
49
50       --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
55       --count integer
56               How many qixes to draw.  Default 1.
57
58       --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
64       --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
68       --random
69               The qix will wander around the screen semi-randomly.   This  is
70               the default.
71
72       --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
76       --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
81       --hollow
82               The opposite of --solid; this is the default.
83
84       --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
89       --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
95       --non-transparent
96               Turns off --transparent.
97
98       --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
103       --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
108       --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
113       --gravity
114
115       --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
120       --fps   Display the current frame rate and CPU load.
121

ENVIRONMENT

123       DISPLAY to get the default host and display number.
124
125       XENVIRONMENT
126               to  get  the  name of a resource file that overrides the global
127               resources stored in the RESOURCE_MANAGER property.
128
129       XSCREENSAVER_WINDOW
130               The window ID to use with --root.
