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. </blockquote> Additional information: Under Unix 64 bit release mode it takes now 74 seconds. But You can use pdftocairo (only 18 seconds) if You accept, that cairo isn't able to render image masks in pattern colorspace correctly :-) Thomas <blockquote cite="mid:4F914CC7.2090100@kabelmail.de" type="cite"> 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 moz-do-not-send="true" 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...
