    GroupDocs.Redaction supports both types of image documents for Optical Character Recognition (OCR): image files, such as printed document scans (PNG, JPG, etc.) embedded images within office documents (PDF, DOCX, etc.) You have to implement IOcrConnector interface and pass the instance to RedactorSettings constructor. For more details, see OCR Usage Basics article.
