## 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 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
