makepattern

       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 fore­
       ground 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  pat­
       tern  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
