Merge XFDF signature with iText

I am using this example code I found online for iTextSharp:

PdfReader template = new PdfReader(“RightsRespPDFJS.pdf”);

XfdfReader xfdfReader = new XfdfReader(“xfdf.xml”);

PdfStamper stamper = new PdfStamper(template, new FileStream(“RightsRespMerged.pdf”, FileMode.Create));

stamper.AcroFields.SetFields(xfdfReader);

stamper.Writer.CloseStream = false;

stamper.Close();
