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
