makepattern − make GMT color pattern from b/w pattern or icon |
|
makepattern 1bit.ras | iconfile −Cfr/g/b −Cbr/g/b |
|
makepattern reads either a Sun 1-bit rasterfile OR a Sun icon file. It then accepts color choices for the foreground and background pixels and colorizes the pattern, writing it as a 8-bit Sun rasterfile on stdout. These patterns may then be used in GMT (3.1 or later) −Gp settings or by psimage. |
|
1bit.ras | iconfile |
|
Either a 1-bit Sun rasterfile (standard format, no RLE) or a Sun icon file (as used in GMT 3.0). |
|
−Cf |
Sets the color for the foreground pixels (the ones) [black]. |
||
|
−Cb |
Sets the color for the background pixels (the zeros) [white]. |
|
Since binary redirection under WIN32 does not work, you must specify the output file with −Gnewfile.ras. This option is only available under WIN32. |
|
To create a colorized red/blue 8-bit Sun rasterfile pattern from the old 3.0-style iconpattern stored in file custom.icon, run makepattern custom.icon −Cf255/0/0 −Cb0/0/255 > custom.ras To create a green/blue 8-bit Sun rasterfile pattern from a 1-bit Sun raster called bits.ras, run makepattern bits.ras −Cf0/255/0 −Cb0/0/255 > colorbits.ras |
