New PDF fails to convert

[georgec]

Hi,

I have been using ImageMagick for a couple of years now. Happlily converting PDFs to PNGs with no trouble (thanks!) But now I have been supplied a batch of PDFs that wont convert and I cant find out why?!

Here are the details

Version: ImageMagick 6.2.5 02/14/06 Q16 under linux

Command: "convert -verbose "./pdf/4/proofs/letterhead.pdf" "./pdf/4/proofs/mastertest.png" 1>output.txt 2>error.txt"

Error text:
GNU Ghostscript 8.01: Unrecoverable error, exit code 1
convert: Postscript delegate failed `./pdf/4/proofs/letterhead.pdf'.

Output text:
Error: /undefined in --token--

What is making this latest batch of PDFs fail to convert to PNG files?

Thanks iin advance for your help!

Mmm - I think that this may be a ghostscript issue rather than a IM thing. I installed IM and GS on a windows machine and converted the problem PDFs with no errors. I think that GS isnt converting the newer PDFs to PS files.
Can anyone comment on this?
Thanks

upgrade your GS? Check version numbers between the one that works and the one that doesn't.
