Hello Dominik
----
Thanks for your answer. I had now a deeper look at the problem. As far
as I can see is the problem not only the multiple font in the doc it
is also the problem, that this function:
PdfXObject (const PdfMemDocument &rSourceDoc, int nPage, PdfDocument
pParent)
includes almost the whole objects of the rSourceDoc in the pParent.
This is a Problem if the SourceDoc contains on some Pages huge
pictures but on the imported page they wouldn't be used.
I saw the comment in FillXObjectFromDocumentPage. This function don’t
remove the unused objects. Hmm... I hope for version 0.7 ;-)
At the moment I don't feel so familiar with pdf and podofo that i can
implement this function by my self. But when I'm a big pdf-guy I'll do
it and give back to the opensource-community.
Best regards,
Stefan Huber
