Hi ,

in one of my uses of PoDoFo , I scan the documents for annotations.

I currently use a PdfMemDocument and get each PdfPage from the PdfPageTree.

as I scan all the pages the memory rises constantly ( reflecting that more data 
is loaded from disk into memory )
and I want to limit the memory usage as much as possible.
I have try to call PdfPageTree ::ClearCache every 10 page I access hoping to 
balance performance with Memory but it doesn't really look like it's helping.

any recommendation and what would be the optimal way to scan a documents for 
all its annotations ?

Thanks . 

Damien
