DESCRIPTION
The qix program bounces a series of line segments around
its window. This is truly the swiss army chainsaw of qix
programs. If you know of one with more display modes, I
want to know about it.
OPTIONSqix accepts the following options:
-window Draw on a newly-created window. This is the
default.
-root Draw on the root window.
-mono If on a color display, pretend we're on a
monochrome display.
-install
Install a private colormap for the window.
-visual visual
Specify which visual to use. Legal values are the
name of a visual class, or the id number (decimal
or hex) of a specific visual.
-segments integer
How many line segments should be drawn. Default
50.
-spread integer
How far apart the endpoints of one segment should
be from the next. Default 8.
-size integer
The maximum distance one endpoint of a segment is
allowed to be from the opposite end of that seg
ment. Default 0, meaning unlimited.
-count integer
How many qixes to draw. Default 1.
-color-shift degrees
If on a color display, the color of the line seg
ments will cycle through the spectrum. This spec
ifies how far the hue of each segment should be
from the next, in degrees on the HSV wheel.
Default 3.
-delay microseconds
How much of a delay should be introduced between
steps of the animation. Default 25000, or about
0.025 seconds.
-random The qix will wander around the screen semi-ran
domly. This is the default.
-linear The opposite of -random: the qix will travel in
straight lines until it reaches a wall, and then
it will bounce.
-solid If this is specified, then the area between the
line segments will be filled in with the appropri
ate color, instead of the qix simply being com
posed of one-pixel-wide line segments. This
option looks really good in color.
-hollow The opposite of -solid; this is the default.
-xor If this is specified, then qix segments will be
drawn and erased with xor, instead of being drawn
in some color and erased in the background color.
This implies -mono, in that only two colors can be
used.
-transparent
If this is specified, and -count is greater than
1, then each qix will be drawn in one color, and
when they overlap, the colors will be mixed. This
looks best in conjuction with -solid.
-non-transparent
Turns off -transparent.
-additive
If -transparent is specified, then this option
means that the colors will be mixed using an addi
tive color model, as if the qixes were projected
light. This is the default.
-subtractive
If -transparent is specified, then this option
means that the colors will be mixed using a sub
tractive color model, as if the qixes were
translucent filters.
-poly int
How many vertices each qix-line should have: the
default is 2, meaning the traditional qix line
shape. Three will yield triangles, and so on.
-gravity
-no-gravity
Whether there should be downward attraction. For
example, the options -gravity -linear will make
everything move in nice smooth parabolas. Gravity
is off by default.
ENVIRONMENT
DISPLAY to get the default host and display number.
XENVIRONMENT
to get the name of a resource file that overrides
the global resources stored in the RESOURCE_MAN
AGER property.
