Hi Stefan, I think you have to do the work manually. Create a new stream object with the modified contents. Afterwards, you can do something like this (pseudo code, you might need to modifiy it slightly):
PdfPage* pPage ...
PdfObject* objectWithNewStream ...
objectWithNewStream->GetStream()->Set( pConcatenatedStreamBuffer,
pConcatenatedStreamBufferLen );
pPage->GetObject().GetDictionary().AddKey( "Contents", objectWithNewStream-
>Reference() );
Hope this helps!
Cheers,
Dominik
