This example showcases the implementation of redaction using rectangle annotation, leveraging the Redaction feature in File formats.
Various types of redactions are demonstrated:
- Displaying text over the redacted area
- Adding an image to the redacted area
- Drawing patterns on the redacted area
- Blacking out the redacted area
- Whitening out the redacted area
Upon selecting areas on a page or across different pages with different redaction options, users can click the `Redact button`. This action redacts the document and reloads it into the PDF Viewer. The redacted document can then be saved or downloaded.
