makepattern
MAKEPATTERN(1gmt) Generic Mapping Tools MAKEPATTERN(1gmt)NAME
makepattern - make GMT color pattern from b/w pattern or icon
SYNOPSIS
makepattern 1bit.ras | iconfile -Cfr/g/b -Cbr/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 set-
tings 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 -Gnewfile.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
