## NAME

makepattern − make GMT color pattern from b/w pattern or icon

## SYNOPSIS

makepattern 1bit.ras | iconfile −Cf r/g/b −Cb r/g/b

## DESCRIPTION

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].

## WIN32 fix

Since binary redirection under WIN32 does not work, you must specify the output file with −G newfile.ras. This option is only available under WIN32.

## EXAMPLES

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 −Cfred −Cbblue > 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 −Cfgreen −Cbblue > colorbits.ras
