Re: Fland and Transparency

[Ansley Manke <ansley.b.manke@xxxxxxxx>]

Hi Bruce,
The transparent option in the fland script uses the PATTERN option for
the SHADE overlay of the land mask.  The PATTERNs are not implemented
for Ferret's -gif or -batch modes, but you can make postscript output 
using a
metafile, or a gif by running Ferret without a command line switch and 
using
the FRAME/FILE=filename.gif  command.  These two sequences work fine:

 > ferret
 yes? use etopo20
 yes? shade/pal=land_sea rose
 yes? go fland 20 black transparent
 yes? frame/file=gfile.gif

  > ferret
  yes? set mode meta
  yes? use etopo20
  yes? shade/pal=land_sea rose
  yes? go fland 20 black transparent
 yes? exit

 > Fprint -o pfile.ps metafile.plt
