With ImageMagick 6.7.1-0 2011-08-03 Q16 and Ghostscript 9.02 (2011-03-30) (all compiled with default ./configure) i get only a 'Segmentation Fault'

Is anyone able to reproduce?

I'm able to reproduce it.

ImageMagick 6.6.5-6 2010-12-10 Q16 http://www.imagemagick.org
GPL Ghostscript 8.71 (2010-02-10)
Gentoo

I've got the same output.

Removing the density argument ( IIRC the default density is 72 ) it works.. so, I suppose it's a free tmp space problem.

[jgonera]

I "solved" the issue by giving up on imagemagick (it's just buggy in this case, no discussion) and using directly ghostscript. Works reliably, is faster, and doesn't use that much memory at all!

Sample ghostscript invocation for pdf -> jpeg conversion follows.

Code: Select all

ghostscript -q -dBATCH -dNOPAUSE -sDEVICE=jpeg -r200x200 -sOutputFile=page_%02d.jpg file.pdf

Your PDF converts fine for us with ImageMagick 6.7.1-8 and Ghostscript 9.02 (no segmentation fault). We recommend using Ghostscript directly if all you want is a direct conversion without any additional image processing operations. See Using Ghostscript Directly @ http://www.imagemagick.org/Usage/text/#ghostscript.
