   Neevia.PDFsign NVsign = new Neevia.PDFsign();
   int retVal;

   NVsign.CertificateFile = "c:\cert.pfx";
   NVsign.CertificatePassword = "pwd";

   NVsign.TimeStamp = true;
   NVsign.TimeServerURL = "http://tsa.neeviaPDF.com/tsa";

   NVsign.X = 0;
   NVSign.Y = 0;
   NVSign.Width = 6;
   NVSign.Height = 2;
   NVSign.Units = 1;

   NVSign.ViewType = 2;
   NVSign.Image = "c:\stamp.jpg";

   NVSign.Reason = "I am the creator of this document";
   NVSign.TextColor = "#0000FF";

   retVal = NVsign.SignPDF(@"c:\in.pdf",@"c:\out.pdf");
   if (retVal != 0) {
     MessageBox.Show("Error code = " + retVal.ToString());
   } else {

I was looking for a product that could place watermarks on very large PDF files (some of them over 30 thousand pages) in as less time as possible. After testing many tools I found Neevia PDFstamp. It did the job!
