The concept of page numbers doesn't exist in PDF. The number of the page is *calculated* based on the occurrence of (the reference to) the page dictionary in the page tree. If you have a page dictionary, you need to know it's position in the page tree. You'll discover that a page dictionary has a Parent entry. This parent entry refers to a /Pages dictionary. This /Pages dictionary can either be the root of the page tree or a child of another /Pages dictionary. Read "The ABC of PDF with iText" for more info: https://leanpub.com/itext_pdfabc (this book is under construction). The page number that is visible to humans on the actual rendered page is just a couple of glyphs rendered at an arbitrary coordinate on a canvas. You can't easily extract the page number from the content stream of a page. ------------------------------------------------------------------------------ Learn Graph Databases - Download FREE O'Reilly Book "Graph Databases" is the definitive new guide to graph databases and their applications.
