public class Destination
extends java.lang.Object

The Destination class 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 outline items, annotations, or actions.

Destination can be associated with outline items, annotations, or actions. In each case the destination specifies the view of the document to be presented when one of the respective objects is activated.

The Destination class currently only supports the Destination syntaxes, [page /XYZ left top zoom], other syntax will be added in future releases. The syntax [page /XYZ left top zoom] is defined as follows:

• page - designated page to show (Reference to a page).
• /XYZ - named format of destination syntax.
• left - x value of the upper left-and coordinate.
• top - y value of the upper left-hand coordinate.
• zoom - zoom factor to magnify page by.

A null value for left, top or zoom specifies that the current view values will be unchanged when navigating to the specified page.

1.0
