Error when converting large PDFs to JPEG

[blokey]

Hi, I'm experiencing the following error on a host when converting certain PDFs with in excess of 200 pages to JPEG:

Code: Select all

Command line used:

Code: Select all

convert -colorspace Transparent -quality 90% -density 112x112 -filter lanczos -resize '450x650>' source.pdf page.jpg

Version of ImageMagick: 6.4.3, gs: 8.63.

I'm not sure if this is a problem with ImageMagick or GhostScript, but the conversion is successful with ImageMagick 6.3.7 / gs 8.62 on another machine. Could it be a resource limit problem? I'd appreciate any insight! Cheers.

To track the problem we need to reproduce it. Can you post a URL to a sample PDF or send a PM?

Thanks for the quick response. One PDF that fails is here:

Apologies for the size (~50MB).

Add -limit memory 1mb -limit map 1mb to your command line. The conversion completed for us-- we're using ImageMagick-6.4.4-1.

The -limit arguments worked a treat! There was also a permissions issue with the location of the temporary files, so it's all fixed now. Thanks for your help.
