[scribus-dev] GSOC: PDF Embedding

[Thach Tran]

I'm not sure it would be any good for PoDoFo, you could take a look at  
pdf_analyzer.cpp. It mostly parses the page content stream and return  
the used color spaces, used fonts, and see if there's transparency.  
The returned values are very simple structs that I put together for  
the purpose of preflighting. I would imagine if in the context of  
PoDoFo, you would want to return the appropriate PoDoFo's objects. And  
about the code, yes, it's mostly C++ with a few Qt classes which are  
just convenient data structures which can easily be replaced.
