       qix - bounce colored lines around a window

       qix  [-display  host:display.screen]  [-foreground  color] [-background
       color] [-window] [-root] [-mono] [-install] [-visual visual] [-segments
       int]   [-spread  pixels]  [-size  pixels]  [-count  int]  [-color-shift

       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.

       qix 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 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

       -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  segment.   Default  0,  meaning

       -count integer
               How many qixes to draw.  Default 1.

       -color-shift degrees
               If  on  a  color  display,  the color of the line segments will
               cycle through the spectrum.  This specifies 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-randomly.  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 appropriate color,  instead  of  the
               qix  simply  being  composed  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.

               If  this  is specified, and -count is greater than 1, then each
               qix will be drawn in one color, and when they overlap, the col-
               ors will be mixed.  This looks best in conjuction with -solid.

               Turns off -transparent.

               If  -transparent  is specified, then this option means that the
               colors will be mixed using an additive color model, as  if  the
               qixes were projected light.  This is the default.

               If  -transparent  is specified, then this option means that the
               colors will be mixed using a subtractive 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  tri-
               angles, and so on.


               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.

       DISPLAY to get the default host and display number.

               to  get  the  name of a resource file that overrides the global
               resources stored in the RESOURCE_MANAGER property.
