        {
            string FilePath = Path.Combine("~/CapturedImage/Image.jpg");
            int x = Convert.ToInt32(X.Value);
            int y = Convert.ToInt32(Y.Value);
            int w = Convert.ToInt32(W.Value);
            int h = Convert.ToInt32(H.Value);
            //System.Drawing.Image image = Bitmap.FromFile(HttpContext.Current.Request.PhysicalApplicationPath + @"\CapturedImage\" + DateTime.Now.ToString("dd-MM-yy hh-mm") + ".jpg");
            System.Drawing.Image image = Bitmap.FromFile(HttpContext.Current.Request.PhysicalApplicationPath + @"\CapturedImage\Image.jpg");
            Bitmap bmp = new Bitmap(w, h, image.PixelFormat);
            Graphics g = Graphics.FromImage(bmp);
            g.DrawImage(image, new Rectangle(0, 0, w, h), new Rectangle(x, y, w, h), GraphicsUnit.Pixel);
            //bmp.Save(HttpContext.Current.Request.PhysicalApplicationPath + @"\CroppedImage\" + DateTime.Now.ToString("dd-MM-yy hh-mm") + ".jpg", image.RawFormat);
            bmp.Save(HttpContext.Current.Request.PhysicalApplicationPath + @"\CroppedImage\Image.jpg", image.RawFormat);
            //imgCapture.ImageUrl = @"\CroppedImage\" + DateTime.Now.ToString("dd-MM-yy hh-mm") + ".jpg";
            imgCapture.ImageUrl = "~/CroppedImage/Image.jpg";
