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.
starfish 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.
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.
How much of a delay should be introduced between steps of the animation. Default
10000, or about 1/100th second.
How long to wait between shifing the colormap by one step. Default 100000, or
about 1/10th second.
How wide each color band should be. Default 0, meaning random (the chosen value
will be between 0 and 15.)
How quickly the objects should rotate at each step. Default 0, meaning random
(the chosen value will be between 0 and 12 degrees.)
How many colors to use. Default 200. The more colors, the smoother the transi-
tions will be, and the nicer the resultant images.
Whether to do colormap cycling. Default true.
How long to run before choosing a new shape. Default 30 seconds.
When duration expires, how long to wait before starting a new run. Default 5 sec-
If blob option is specified, then the raw shapes will be shown, instead of a field
of colors generated from them.
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.
