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
      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 -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, try

      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, try

      makepattern bits.ras -Cf0/255/0 -Cb0/0/255 > colorbits.ras
