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
