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.
OPTIONS
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
-
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.
- -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.
- -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 generated from them.
- -fps
-
Display the current frame rate and CPU load.
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.
