## 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
