NAME

        starfish - radially-symmetric throbbing colormap-hacking graphics demo
 

SYNOPSIS

        starfish  [-display  host:display.screen]  [-foreground  color] [-back-
        ground color] [-window] [-root]  [-mono]  [-install]  [-visual  visual]
        [-delay  usecs]  [-delay2 secs] [-thickness pixels] [-rotation degrees]
        [-duration seconds] [-colors int] [-blob] [-no-blob] [-fps]
 

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  sec-
                onds.
 
        -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.
