You could try
ps2pdf -dEPSCrop foo.eps
assuming your bounding box makes sense. If you run windows you may
need to play with Ghostscript paths or install Cywgin to get the above
happening.
Good luck.

You are right that ImageMagick is not the solution
here, since it is software for working with raster
files, and must go through a raster intermediary to
go from one vector format (PostScript) to another (PDF).
I use Adobe Acrobat and Distiller for this purpose,
but this is reasonably expensive (although solid and
with LOTS of features) software. I see advertisements
for less expensive alternatives from time to time.
These routines can be called from within IDL using the
SPAWN command in exactly the same way ImageMagick is
used from within the Coyote Graphics programs.
Another solution I have used is to print PostScript
graphics routines directly to a PDF file via the
PRINTER device in IDL and a PDF printer.
http://www.idlcoyote.com/fileio_tips/pdffiles.html
This solution is nice and convenient, but it requires
the user to directly choose the PDF printer driver. I've
never been able to figure out a way to do this
programmatically.
Cheers,
David

ps2pdf Test.ps
and the result of that is good
filesize is 50K
cheers
