            string f = Server.MapPath(string.Format("~/Temp/{0}.pdf",fileName));
            PdfWriter.GetInstance(doc, new FileStream(f, FileMode.Create));
            doc.Open();
            ///
            /// A4 Size
            ///
            int width = 585;

            string p = Server.MapPath(string.Format("~/Temp/{0}.bmp",fileName));
            image.Save(p);
            iTextSharp.text.Image i = iTextSharp.text.Image.GetInstance(p);
            doc.Add(i);
            doc.Close();
            File.Delete(p);
            ///
            /// use pdf file
            ///
            File.Delete(f);            
        }
