  You can tweak the default one with the following trick:

  * have an environment variable RUBYLIB pointing to a directory in your
homedir, such as RUBYLIB=$HOME/lib/ruby
  * copy the standard rbconfig.rb file and dump it there, where you can
safely modify it

  Ruby should find $HOME/lib/ruby/rbconfig.rb before the standard one,
and the installation should now work (or at least go somewhat further).
You can make sure your modified version of rbconfig.rb is used by adding
a puts statement at the beginning of it.

  Cheers,

  If you have xpdf installed, the following should do the job:

  pdftops -eps -paper match file.pdf

  I'm not sure the -paper match bit is necessary. Apparently, pdf2ps
(from gostscript) also does the job with a correct bounding box:

  pdf2ps file.pdf file.eps

  I'm confused: the bit with pdftops does not work while I was sure it
worked last time I checked, and the second does work fine. That might
depend on the versions installed on your computer, though, so I'm
keeping both methods.

  Just for the record, convert works with bitmap images, so there's no
wonder why you don't like the output so much...

  Cheers,

	Vincent

  Hmmm. That is more complex. Both methods produce a decent bounding
box, excepted that, for some reason I don't understand, gv does not take
it into account when the file has been produced by pdftops, while it
does for pdf2ps.

  So, both methods should work, if what you're looking for is inclusion
into another document.

  Cheers,

Hi there -- I used

  $ pdftops -eps filename.pdf

with success as well.  (pdftops is in the xpdf-utils in Debian; I'm
not sure in other distros).  FYI, in my box:

  $ pdftops -v
  pdftops version 3.01
  Copyright 1996-2005 Glyph & Cog, LLC

Some PDF specific features (like transparency) will get lost but
pdftops worked like a charm for me...

So I've tried the pdf2ps command and I'm getting the same results.

Comparison between the PDF and the PS documents show an obvious 
degradation in quality.  The PS document looks very blurry/hazy.

  It really shouldn't. Two questions:

  * are you using the same tool for looking at both the PDF and EPS
files ? xpdf shows graphs reasonably well, while gv's antialiasing
really doesn't do a good job there (but then, it's reasonably faster)
- I have a strong feeling this might be the problem here [1];
  * do you have pixmaps in the PDF file ? Although I don't think they
could get degraded, it is a possibility (to make sure this isn't the
case, use pdfimages to extract images from the original file, convert
it to ps and back to PDF and extract the images again; diff should
show no differences).

[1]: as far as I know, while there are at least two unrelated open
source engines for rendering PDF (ghostscript and xpdf), there is only
ghostscript that renders postscript files, so most likely anything
that displays postscript files is likely to rely on it.

  Cheers,

      Vincent

Some time ago I settled on this script: http://pastebin.com/f3420e11c
which runs ghostscript in batch mode and uses -sDEVICE=epswrite

The result in gv looks worse than the original tioga-produced PDF in the
same gv. However, on print I cannot distinguish the two.

For me, pdftops -eps produces EPS with better aliased fonts when viewed
in gv, but the page size in gv is wrong (%%Bouniding Box seems to
be almost correct, %%HiResBoundingBox is missing).

This might be off the mark, but is that bounding box problem in eps
files something a script like fixbb can fix?

  http://www.gnuplot.info/scripts/files/fixbb

For me, the combo of "pdftops -eps" and "fixbb" produce eps files that
can be included perfectly in LaTeX.

Thanks everyone for all the helpful advice.

I probably should have said this earlier, but I'm running Mac OS 
10.5.2.  This version of the Mac OS comes with pdf2ps which was giving 
me the problems I described earlier

However, I went and installed xpdf-tools from 
http://users.phg-online.de/tk/MOSXS/xpdf-tools-3.dmg and now I have pdftops.

Running "pdftops -eps file.pdf" creates an EPS file that is perfectly 
indistinguishable from the original Tioga PDF and ready for insertion 
into LaTeX documents.

Problem solved.
