Hi ...

i have installed IM 6.2.4 and GS 8.15.3 on a debian etch 4.0.

I want to convert a 180 sheet PDF to JPG but i get the error: convert: Postscript delegate failed `file.pdf'.

My first idea was to crop the PDF with Acrobat smaller in smaller sheet peaces 1-30, 31-60, 61-90, 91-120, 121-150, 151-180.
The try to convert the PDF 1-30, succeded. I got 30 JPGs. When I tryed to convert a PDF 1-60 sheets, same error (see above).

I think the PDF is to big! Filesize is 12MB. Or has ImageMagick any limitation? I readed that GhostScript is the problem. Any ideas?

Thanx alot.

Can you post a URL to your image. We need to download it and determine if the problem is with the PDF, with Ghostscript, or with ImageMagick.

The Postscript converted without complaint with this command:
  • convert -limit memory 1mb -limit map 2mb test.pdf image.jpg
We're using ImageMagick 6.5.2-1.

Does this command sequence work for you?
  • convert logo: logo.ps
    convert logo.ps logo.png
If not, its possible you do not have Ghostscript installed properly.
