I'd like to ask for support or redaction, similar to itextpdf.com/itext7/pdfSweep
Sometimes You must remove address information from invoice. Adding rectangle on top isn't an option, because You could still copy paste text and get that data.
Ideally GemBox.Pdf should remove text behind given rectangle and draw new rectangle.
This feature request has been implemented and is available in the latest versions of GemBox.Pdf.
