Ouch :-/
Of course it is either ps.find(re) or ps.find(QRegExp("w\\d+h\\d+"), is any of
the two better?

I've never used a regexp to capture anything so i thought it would be faster
to do that than learning how to capture in a QRegExp, is it much worse to use
that?

That is because doing paintDevice::width() and paintDevice::height() on the
argument of the method always returns the pageSize of A4 (default page size
here, calling pageSize() always return A4 too even when option("PageSize")
says otherwise), i would need to do setPageSize on "printer" as i do on the
dummy printer but i don't know if that would have side consequences so i
thought it would be safer to do it on a dummy printer and i don't see any bad
consequence.
