业务需要动态给图片增加文字（书本的封面图片），修改字体大小、字体、颜色、控制位置

测试代码：

				?

									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");
