Object Model
Syntax
public class AnnRedactionObject : AnnRectangleObject, IAnnHeaderIAnnObjectIAnnRectangle  
'Declaration
 
Public Class AnnRedactionObject

   Implements IAnnHeaderIAnnObjectIAnnRectangle 
'Usage
 
Dim instance As AnnRedactionObject

            

            
public ref class AnnRedactionObject : public AnnRectangleObject, IAnnHeaderIAnnObjectIAnnRectangle  
Remarks

The redaction annotation object is a rectangle with default properties that are appropriate for blacking out an area. The Realize method lets you block the area on the image with the current object brush value. The Restore method lets you restore the area back. For more information about the redaction annotation object refer to AnnRedactionObject for WPF. For more information about the automated redaction annotation object, refer to WPF Annotation Objects - Automated Features.

If you are interested in locking an object, refer to Implementing WPF Annotation Security.
