halo - draw circular patterns
SYNOPSIS
halo [-display host:display.screen] [-foreground color] [-background color] [-window] [-root] [-mono] [-install] [-visual visual] [-count
int] [-delay usecs] [-mode seuss | ramp | random ] [-animate] [-colors integer] [-cycle] [-no-cycle] [-cycle-delay usecs]
DESCRIPTION
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.
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_MANAGER property.
