Hi Mike, If you change the behavior of PdfContentsTokenizer::GetNextToken() to span across streams, could you please provide a flag to toggle this behavior? For some users (like me) it might be important to change back to the "old" behavior which DOES NOT span across streams.
I have got an application which parses through streams and replaces the content of each single stream without changing the overall structure of the streams. I think that this wouldn't be possible any longer if PdfContentsTokenizer::GetNextToken() did not detect stream boundaries anymore. Thanks in advance!
