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  psim-
     age.

     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
