Class: Bookmark

Core.PDFNet. Bookmark


new Bookmark()

A %PDF document may optionally display a document outline 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 Bookmarks (sometimes called outline items), which serve as a 'visual table of contents' to display the document's structure to the user. Each Bookmark has a title that appears on screen, and an Action that specifies what happens when a user clicks on the Bookmark. The typical action for a user-created Bookmark is to move to another location in the current document, although any action (see PDF::Action) can be specified. Bookmark is a utility class used to simplify work with %PDF bookmarks (or outlines; see section 8.2.2 'Document Outline' in %PDF Reference Manual for more details).
