int pw = 60;
            int ph = 15;
            int px =80;
            int py = 100;

            ppath = @"d:\123.jpg";
            Bitmap b = new Bitmap(ppath);
                //剪裁图片
                RectangleF rec = new RectangleF(px, py, pw, ph);
                Bitmap nb = b.Clone(rec, System.Drawing.Imaging.PixelFormat.Format32bppArgb);
//剪切后并读入到流中去
                Stream ms = new MemoryStream();
                nb.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg);
