Re: converting metafile to EPS

[Andrew Wittenberg <Andrew.Wittenberg@xxxxxxxx>]

Hi Hein,

At least on our systems (RH Linux 7.3 and IRIX 6.5), the Ferret PostScript
output is almost valid EPS, it just needs a couple of small changes to the
PostScript file.  It might be simple for the developers to add these
commands at the end of the Fprint script.

(By valid EPS, I mean that the resulting file works in LaTeX.)

For portrait-oriented graphics, I do the following to create an EPS file:

Fprint -o out.ps -p portrait -R metafile.plt
awk '{print ($1=="%\!PS-Adobe-1.0" ? "%\!PS-Adobe-2.0 EPSF-1.2" : $0)}' <out.ps >out.eps


For landscape-oriented graphics, I do:

Fprint -o out.ps -p landscape -R metafile.plt
cat out.ps | sed \
  -e 's/^%\!PS-Adobe-1.0$/%\!PS-Adobe-2.0 EPSF-1.2/' \
  -e 's/\(%%BoundingBox: *\)\([0-9][0-9]*\)  *\([0-9][0-9]*\)  *\([0-9][0-9]*\)  *\([0-9][0-9]*\)/\1\3 \2 \5 \4\\
%%Orientation: Landscape\\
612 792 translate\\
180 rotate/' \
  > out.eps
