ps2pdf?

There exists the -dEPSCrop option but in case you have to handle EPS files
that have a wrong bounding box (as a result of rounding or default paper
size or the like) you can also insert specific pdfmarks to force a correct
media box (using a HighResBoundingBox comment for example):

    /pdfmark where {pop} {userdict /pdfmark /cleartomark load put} ifelse
    [{ThisPage}<</MediaBox [ 30.5 403 558.3 700 ] >> /PUT pdfmark

(Have a look at <http://www.pdflib.com/more/pdfmark.html> and the PDF
documentation for more details about pdfmarks)

BTW: Does anyone have a clue whether I can use GS to extract both Media- and
TrimBox from _PDF_ files?
