Quite a nasty one imho ;) Thanks for getting back to me, sorry for the delay. </pre> </blockquote> Hey Ralph! In the meantime I found some time to have a look into it: The PDF has 12153 image masks in pattern colorspace. My first try to render it under Windows with pdftoppm compiled in debug mode dies after 22 minutes with out of memory. Then I encountered, that my implementation of colorizing image masks in pattern colorspace in splash could be optimized. I gave it a try, and now I'm able to render it in 250 seconds (still Windows debug mode). It's still not so fast, but at least it works. My problem now is, that my code base is in the meantime completely different than git master, because Albert wasn't able to commit my DeviceN implementation and suspend it until 0.22. Therefore I opened a bug: <a class="moz-txt-link-freetext" href="https://bugs.freedesktop.org/show_bug.cgi?id=48964">https://bugs.freedesktop.org/show_bug.cgi?id=48964</a>. I need to discuss it with Albert in which order my enhancements could be committed. At least I'll regtest my changes coming weekend, and perhaps I create a patch for it only... BTW, it would probably help if You can send the PDF also to Albert...

Looking at an strace shows that it's doing *something* but it's taking much longer than expected (at least over a few minutes). This is present on 0.18.3 and 0.19.2. I would attach the file to a bug post, but I'd rather email it out directly as it's a customers PDF and not mine.
