Hi Mike, Qt 5 includes QPdfWriter [0] that makes generating multi-page
PDFs a breeze. I haven't used it myself, but the documentation makes
it look easy. I'm surprised there's no corresponding QPdfReader
(perhaps it's still a WIP?), but since you're using HTML as input you
can simply use QtWebKit to load the files and then render them to a
QPaintDevice (image, pdf, etc). There's an example in the docs showing
you how to do just that [1], but you're going to have to glue the
pieces together yourself to iterate over your 60 HTML files, rendering
and calling QPdfWriter::newPage() where appropriate.
