PDF redaction

Hello, I am in the process of evaluating the complete Document library for one of our project requirement. One of the requested feature is redacting a text or a specific area in a PDF document to hide any sensitive PII data in the document. I couldn't able to find the example in the documentation. Please let me know Thank you.

Hi In order to perform redacting we can use PdfCompositeField compositeField = new PdfCompositeField(font, PdfBrushes.Black, "Page {0} of {1}{2}", pageNumber, count, datetimefield); compositeField.Bounds = new RectangleF(0, 0, 250, 100); compositeField.Draw(doc.Pages[0].Graphics, new PointF(0, 0)); the above code .
