Hi Thach,

I didn’t realise that we were so close to the end!
I’ve started to hack around your code to bring answers to the difficult question 
"What do we do when source content stream and target PDF document have color 
space mismatch?" The way we handle it for other colored resources (images) is 
to perform the conversion or to attach needed material (ICC) to do it. In the 
case of embedded PDF pages, as you’ve pointed out,  we know about target color 
space too late in the process to just insert an item in pre-flighter and 
delegate the pain to the user :-) but even though we would know target color 
space sooner, as long as we don’t do color conversion of objects in the 
content stream of placed PDF pages, we would be unable to take appropriate 
measures in case of mismatch*.

I stop my digression here!
Now, I think we can spend the last week at preparing the future. I’m already  
happy with the code you wrote and in my opinion you can let it as is (just 
continue to keep in sync with Trunk). What we need is to see it documented to 
be able to easily step into it.
I would like to have more methods documentations in PDFAnalyzer and esp. where 
you created public interfaces (PDFAnalyzer::inspectCanvas). Writing how it can 
be extended will be good too, and more generally summarize all the work you 
done for the program and how you think we can continue (or even rewrite!) it 
would be interesting.

Someone else?


* Would be interesting to look if it’s such a huge job to do conversion though 
and how it could be integrated in images CM system.
