Bounds Property

Summary

Link location and position in the page.

Syntax

C++/CLI

Java

Python

public LeadRectD Bounds { get; set; }

public:  
   property LeadRectD^ Bounds 
   { 
      LeadRectD^ get() 
      void set(LeadRectD^ value) 
   }

public LeadRectD getBounds() 
public void setBounds(LeadRectD value)

Bounds # get and set (DocumentLink)

Property Value

The link location and position in the page in document coordinates. Default value is empty rectangle.

Remarks

Viewer applications can use this value to provide UI support for links. Typically, change the pointer when it hovers over the link Bounds and perform the action when the user clicks on this area: either go to Target if this is an internal link or invoke the hyperlink in Value if this is an external link depending on LinkType.

This value is in document coordinates. Refer to Document Library Coordinate System for more information.
