-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Well, it's the same bad design as the Poppler qt4 frontend uses.
But really, just consider it part of the description of "Page::size": "returns the size of the page at 72 DPI". (So the declaration of Page::size is the single of definition. Documentation is really bad though. :-\) It is completely equivalent to assuming some physical unit and returning the physical page size. I wouldn't call it magical, just convention on what is meant by size.
