string path = @"E:\cover.png";
      Bitmap bmp = new Bitmap(path);
      Graphics g = Graphics.FromImage(bmp);
      String str = "贤愚经";
      Font font = new Font("仿宋_GB2312", 14, FontStyle.Bold);//设置字体,大小,粗细
      SolidBrush sbrush = new SolidBrush(Color.White);//设置颜色
      int base_left = 10;
      int left_space = 30;
      int base_top = 27;
      int top_space = 27;
      for (int i = 0; i < str.Length; i++)
      {
        if (i > 13)
        {
          continue;
          g.DrawString(str[i] + "", font, sbrush, new PointF(base_left + (left_space * 2), base_top + (top_space * (i - 14))));
        }
        else if (i > 6)
        {
          g.DrawString(str[i] + "", font, sbrush, new PointF(base_left + (left_space * 1), base_top + (top_space * (i - 7))));
        }
        else
        {
          g.DrawString(str[i] + "", font, sbrush, new PointF(base_left, base_top + (top_space * i)));
        }
      }
      //MemoryStream ms = new MemoryStream();
      //bmp.Save(ms, System.Drawing.Imaging.ImageFormat.Bmp);
      bmp.Save(@"E:\cover1.png");
