Hi Riad,
I've attached a patch that does formatted PDF output. Nested Phrase
objects were needed, as was some XML parsing. No wonder you left it as
unformatted output in the first place! :)
I've hardwired the PDF output for "vertical arrangement" (question on
top row, answer on bottom row). Maybe a new export option is needed in
the GUI (say "PDF (vertical)" and "PDF (horizontal)").
I'll leave you to factor in my patch. Let me know when you're done, then
I'll update from svn trunk. Thanks!
Regards
Jonathan
