|---|
| 10 | .SH OPTIONS |
|---|
| 11 | .I goop |
|---|
| 12 | accepts the following options: |
|---|
| 13 | .TP 8 |
|---|
| 14 | .B \-window |
|---|
| 15 | Draw on a newly-created window. This is the default. |
|---|
| 16 | .TP 8 |
|---|
| 17 | .B \-root |
|---|
| 18 | Draw on the root window. |
|---|
| 19 | .TP 8 |
|---|
| 20 | .B \-mono |
|---|
| 21 | If on a color display, pretend we're on a monochrome display. |
|---|
| 22 | .TP 8 |
|---|
| 23 | .B \-install |
|---|
| 24 | Install a private colormap for the window. |
|---|
| 25 | .TP 8 |
|---|
| 26 | .B \-visual \fIvisual\fP |
|---|
| 27 | Specify which visual to use. Legal values are the name of a visual class, |
|---|
| 28 | or the id number (decimal or hex) of a specific visual. |
|---|
| 29 | .TP 8 |
|---|
| 30 | .B \-count \fIinteger\fP |
|---|
| 31 | How many bubbles to draw per layer. Default: random. |
|---|
| 32 | .TP 8 |
|---|
| 33 | .B \-layers \fIinteger\fP |
|---|
| 34 | How many layers to draw. Default: random, based on screen depth. |
|---|
| 35 | .TP 8 |
|---|
| 36 | .B \-delay \fImicroseconds\fP |
|---|
| 37 | How much of a delay should be introduced between steps of the animation. |
|---|
| 38 | Default 100000, or about 1/10th second. |
|---|
| 39 | .TP 8 |
|---|
| 40 | .B \-transparent |
|---|
| 41 | If \fI\-layers\fP is greater than 1, then each layer will be drawn in one |
|---|
| 42 | color, and when they overlap, the colors will be mixed. This is the default. |
|---|
| 43 | .TP 8 |
|---|
| 44 | .B \-non\-transparent |
|---|
| 45 | Turns off \fI\-transparent\fP. |
|---|
| 46 | .TP 8 |
|---|
| 47 | .B \-additive |
|---|
| 48 | If \fI\-transparent\fP is specified, then this option means that the colors |
|---|
| 49 | will be mixed using an additive color model, as if the blobs were projected |
|---|
| 50 | light. This is the default. |
|---|
| 51 | .TP 8 |
|---|
| 52 | .B \-subtractive |
|---|
| 53 | If \fI\-transparent\fP is specified, then this option means that the |
|---|
| 54 | colors will be mixed using a subtractive color model, as if the blobs were |
|---|
| 55 | translucent filters. |
|---|
| 56 | .TP 8 |
|---|
| 57 | .B \-xor |
|---|
| 58 | Draw with xor instead of the other color tricks. |
