This sample illustrates how to perform redaction using the PDF Viewer. Select regions on one or multiple pages, customize the redaction properties, and then apply them to permanently remove the marked content. You can invoke redaction through the API using RedactAsync. After applying redaction, the updated document is reloaded into the viewer and can be saved or reopened for further use.
