DESCRIPTION
The starfish program draws radially symmetric objects,
which expand, contract, rotate, and turn inside out. It
uses these shapes to lay down a field of smooth colors,
and then rotates the colormap.
OPTIONSstarfish 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.
-delay microseconds
How much of a delay should be introduced between
steps of the animation. Default 10000, or about
1/100th second.
-cycle-delay microseconds
How long to wait between shifing the colormap by
one step. Default 100000, or about 1/10th second.
-thickness pixels
How wide each color band should be. Default 0,
meaning random (the chosen value will be between 0
and 15.)
-rotation degrees
How quickly the objects should rotate at each
step. Default 0, meaning random (the chosen value
will be between 0 and 12 degrees.)
-colors int
How many colors to use. Default 200. The more
colors, the smoother the transitions will be, and
the nicer the resultant images.
-cycle
-no-cycle
Whether to do colormap cycling. Default true.
-duration seconds
How long to run before choosing a new shape.
Default 30 seconds.
-delay2 seconds
When duration expires, how long to wait before
starting a new run. Default 5 seconds.
-blob
-no-blob
If blob option is specified, then the raw shapes
will be shown, instead of a field of colors gener
ated from them.
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.
