The Apryse SDK API is divided into multiple namespaces. The most important are the PDF, SDF, and Filters namespaces.

PDF API
A simple high-level API for manipulating PDF constructs such as pages, interactive forms, bookmarks, graphical elements on the page, and so on.

SDF API
A powerful low-level API for manipulating every aspect of a PDF document. To use the SDF API, you must be familiar with PDF file structure (documented in the PDF Reference Manual)

Filters API
A robust utility API that deals with various compression and encryption schemes used in PDF documents. Unless planning to implement a custom encryption or compression scheme in PDF documents, you will only need a very basic knowledge of the filters.
