allow setPage() functionality

[kwroblewski]

It would be very helpful if I could specify which page I want to render something to.

A good example for why this might be needed is if I wanted to render a "Page 1 of 5" footer, but I don't know until I am done how many pages I actually end up having.

With a setPage() method, I can simply iterate back through my pages and insert things after I have already moved onto new pages.

I am needing this also, but for a different reason. I am loading images in a loop, and frequently i have moved onto the next page of text before the image load comes back so it writes in the correct location, but on the wrong page.

I agree we need setPage() functionality, but as a workaround, have all your
images load without callback, once everything is done then start PDF
generation.

Unless you're working with a seriously large amount of images this will
finish in the same amount of time.

That's one solution. However, here's a better example for this need:

I want to render something like "Page 1 of 12" on each page. But since I don't know how many pages total I will have until I am done rendering the whole document, I have to go back on each page to do this once I have rendered all pages and know how many total there are.

+1 on this. I want to render "Page x of N" too.
