How do you programmatically redact PDF FIles?

Question

Adobe Acrobat has the ability to redact PDF files (that is, actually remove the information, rather than simply drawing a black box on top of it). I would like to use this feature programmatically. To redact using the GUI you select the Mark for Redaction Tool, draw it over the text to be redacted, then Apply Redactions.

Is there any way to do this programmatically, either through AppleScript or some other way?

I know the (X,y) location of the text to be redacted.

Thanks!

You can use GroupDocs.Redaction for .NET to programmatically redact text in the PDF documents. You can perform the exact phrase, case-sensitive and regular expression redaction of the text. This is how you can perform the exact phrase redaction.

using (Document doc = Redactor.Load("D:\\candy.pdf"))
{
     doc.RedactWith(new ExactPhraseRedaction("candy", new ReplacementOptions("[redacted]")));
     // Save the document to "*_Redacted.*" file.
     doc.Save(new SaveOptions() { AddSuffix = true, RasterizeToPDF = false }); 
}
