I have a large (over 2 GB...) PDF file that is organized with nested bookmarks into chapters and pages. Each top-level chapter may contain 1-n pages with around 1,000 or so chapters in each PDF file.

I need to split this file out into a series of smaller PDF files on the chapter-level bookmark using the iTextSharp.PDF library.

Does anyone have an experience along these lines and, if so, could you share, please? Sample code in C# would be appreciated also.

an extra bookmarked blank page must be inserted at the end of the file so that the application can get the ending page number.
