8 The \fIqix\fP program bounces a series of line segments around its window.
9 This is truly the swiss army chainsaw of qix programs. If you know of one
10 with more display modes, I want to know about it.
13 accepts the following options:
16 Draw on a newly-created window. This is the default.
19 Draw on the root window.
22 If on a color display, pretend we're on a monochrome display.
25 Install a private colormap for the window.
27 .B \-visual \fIvisual\fP
28 Specify which visual to use. Legal values are the name of a visual class,
29 or the id number (decimal or hex) of a specific visual.
31 .B \-segments \fIinteger\fP
32 How many line segments should be drawn. Default 50.
34 .B \-spread \fIinteger\fP
35 How far apart the endpoints of one segment should be from the next.
38 .B \-size \fIinteger\fP
39 The maximum distance one endpoint of a segment is allowed to be from
40 the opposite end of that segment. Default 0, meaning unlimited.
42 .B \-count \fIinteger\fP
43 How many qixes to draw. Default 1.
45 .B \-color\-shift \fIdegrees\fP
46 If on a color display, the color of the line segments will cycle through
47 the spectrum. This specifies how far the hue of each segment should be
48 from the next, in degrees on the HSV wheel. Default 3.
50 .B \-delay \fImicroseconds\fP
51 How much of a delay should be introduced between steps of the animation.
52 Default 25000, or about 0.025 seconds.
55 The \fIqix\fP will wander around the screen semi-randomly. This is the
59 The opposite of \fI\-random\fP: the \fIqix\fP will travel in straight lines
60 until it reaches a wall, and then it will bounce.
63 If this is specified, then the area between the line segments will be filled
64 in with the appropriate color, instead of the \fIqix\fP simply being composed
65 of one-pixel-wide line segments. This option looks really good in color.
68 The opposite of \fI\-solid\fP; this is the default.
71 If this is specified, then qix segments will be drawn and erased with xor,
72 instead of being drawn in some color and erased in the background color.
73 This implies \fI\-mono\fP, in that only two colors can be used.
76 If this is specified, and \fI\-count\fP is greater than 1, then each qix
77 will be drawn in one color, and when they overlap, the colors will be mixed.
78 This only works on \fBPseudoColor\fP displays. This looks best in
79 conjuction with \fI\-solid\fP.
82 Turns off \fI\-transparent\fP.
85 If \fI\-transparent\fP is specified, then this option means that the colors
86 will be mixed using an additive color model, as if the qixes were projected
87 light. This is the default.
90 If \fI\-transparent\fP is specified, then this option means that the
91 colors will be mixed using a subtractive color model, as if the qixes were
97 to get the default host and display number.
100 to get the name of a resource file that overrides the global resources
101 stored in the RESOURCE_MANAGER property.
