        PdfWriter.GetInstance(document, new FileStream(Request.PhysicalApplicationPath + "\\PDFfile.pdf", FileMode.Create));
        document.Open();
        Image pdfImage = Image.GetInstance(Server.MapPath("logo.png"));

        pdfImage.ScaleToFit(100, 50);

        pdfImage.Alignment = iTextSharp.text.Image.UNDERLYING; pdfImage.SetAbsolutePosition(180, 760);

        document.Add(pdfImage);

        iTextSharp.text.html.simpleparser.HTMLWorker hw = new iTextSharp.text.html.simpleparser.HTMLWorker(document);
        hw.Parse(new StringReader(HTML));
        document.Close();
        ShowPdf("PDFfile.pdf");
    }
