8 The \fIstarfish\fP program draws radially symmetric objects, which expand,
9 contract, rotate, and turn inside out. It uses these shapes to lay down a
10 field of smooth colors, and then rotates the colormap.
13 accepts the following options:
16 Draw on a newly-created window. This is the default.
19 Draw on the root window.
22 If on a color display, pretend we're on a monochrome display.
25 Install a private colormap for the window.
27 .B \-visual \fIvisual\fP
28 Specify which visual to use. Legal values are the name of a visual class,
29 or the id number (decimal or hex) of a specific visual.
31 .B \-delay \fImicroseconds\fP
32 How much of a delay should be introduced between steps of the animation.
33 Default 10000, or about 1/100th second.
35 .B \-cycle\-delay \fImicroseconds\fP
36 How long to wait between shifing the colormap by one step.
37 Default 100000, or about 1/10th second.
39 .B \-thickness \fIpixels\fP
40 How wide each color band should be. Default 0, meaning random (the chosen
41 value will be between 0 and 15.)
43 .B \-rotation \fIdegrees\fP
44 How quickly the objects should rotate at each step. Default 0, meaning
45 random (the chosen value will be between 0 and 12 degrees.)
48 How many colors to use. Default 200. The more colors, the smoother the
49 transitions will be, and the nicer the resultant images.
54 Whether to do colormap cycling. Default true.
56 .B \-duration \fIseconds\fP
57 How long to run before choosing a new shape. Default 30 seconds.
59 .B \-delay2 \fIseconds\fP
60 When \fIduration\fP expires, how long to wait before starting a new run.
66 If \fIblob\fP option is specified, then the raw shapes will be shown,
67 instead of a field of colors generated from them.
72 to get the default host and display number.
75 to get the name of a resource file that overrides the global resources
76 stored in the RESOURCE_MANAGER property.
