How to draw a PDF file with different font size?

Question

I am currently working on a PDF Reader application. I draw PDF files in a tiled layer with animation.

Now I want to draw PDFs with different font size (not the size specified in PDF). How can I do this?

Answer 1

It's not really possible to do this right, given the nature of the PDF.

Even if you will be able to somehow get in between reading and drawing of PDFs you'll get messed up output in the end.

PDF pages are pretty much fixed in layout and changing font sizes won't make text and other page elements to move and wrap like HTML pages, for example.
