About removing/deleting pages

PDFDoc.PageRemove(itr) only removes the page from document's page sequence. The page and its resources are still available until the document is saved in 'full save mode' with the 'remove unused objects' flag. If you are saving the file in 'incremental mode', the serialized document may contain the content of the removed page.
