access the pdf stream

[José Rodolfo Carrijo de Freitas]

Hello all, 

Does someone know how to access the pdf and the page stream?

 

I need to know the size in bytes of it, and I´m trying to extract the size
of the dictionary, until now, without success.

It would be nice if someone could help, cause I´m stuck in this problem for
a while.

 

Thank you.
