## Detailed Description

A destination defines a particular view of a PDF document, consisting of the following items:

- The page of the document to be displayed.
- The location of the document window on that page.
- The magnification (zoom) factor to use when displaying the page.

Destinations may be associated with bookmarks, or some types of actions. In each case, the destination specifies the view of the document to be presented when the bookmark item or link annotation is opened or the action is performed.
This class offers functions to create destination objects for different zoom modes, and get destination data.
