redactionOptions Property

Summary

Redaction options to use when this document is viewed or converted.

Syntax
TypeScript
JavaScript
Object.defineProperty(DocumentAnnotations.prototype, 'redactionOptions', 
   get: function(), 
   set: function(value) 
) 
redactionOptions: DocumentRedactionOptions; 

Property Value

The redaction options to use when this document is viewed or converted. The default value is null.

Remarks

The default value of null instructs the DocumentViewer and DocumentConverter to not perform any special processing for the annotations objects in the pages of this LEADDocument during viewing or converting.

To apply the annotations, set a new instance of DocumentRedactionOptions in RedactionOptions and modify its options for the desired operations.

For more information, refer to Document View and Convert Redaction.

Example

This example will load a PDF document, then dynamically apply redactions to any word containing "leadtools" found and save it back into an external PDF
