Overview
The halo program draws cool patterns based on circles.
Options
halo 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.
-
-count integer -
How many circles to draw. Default 0, meaning random.
- -mode seuss | ramp | random
-
In seuss mode, alternating striped curves will be drawn.
In ramp mode, a color ramp will be drawn.
random means pick the mode randomly.
-
-delay microseconds -
How much of a delay should be introduced between steps of the animation. Default 100000, or about 0.1 second.
-
-colors integer -
How many colors to use. Default 100.
-
-animate -
If specified, then the centerpoints of the circles will bounce around. Otherwise, the circles will be drawn once, erased, and a new set of circles will be drawn.
-
-cycle
-
-no-cycle -
Whether to do colormap cycling. Default is to cycle.
-
-cycle-delay -
Number of microseconds between shifts of the colormap; default 100000, or 1/10th second.
