PdfOutlineCollection Class

A PDF document may contain a document outline that the conforming reader may display on the screen, allowing the user to navigate interactively from one part of the document to another. The outline consists of a tree-structured hierarchy of outline items (sometimes called bookmarks), which serve as a visual table of contents to display the document’s structure to the user.

PdfOutlineCollection represents a collection of outline items.

Note  Note
This collection is implemented as doubly linked list and therefore methods that use random access (index) are an O(n) operations, where n is Count.
