PDF viewer which caches / prerenders upcoming pages
 

Is there a PDF viewer which will prerender X amount of pages +/- from the current one? I'm writing up documentation, I have to zoom out and scroll through checking it - but the pdf viewers all seem to take forever to render each page, scoll by scroll. I would much rather leave the computer be and do other work while I wait for it to completely render.

It would be a useful feature (I have the same problem), but I don't know of a reader that does this on GNU/Linux.

Depending on your workflow (ie, if you are not editing the PDF directly), a work around is to convert the pdf to an image set (eg using pdftoppm), and then just use an image viewer such as gqview to flick through pages. Not so useful if you have to check indexes and documents links, but okay if you are just proofreading a lot of text.

I _think_ ocular does it, but I'm not sure and I can't check it right now...
