C#如何在图片增加文字的示例代码分享

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");

字体选择：

黑体：SimHei 宋体：SimSun 新宋体：NSimSun 仿宋：FangSong 楷体：KaiTi 仿宋_GB2312：FangSong_GB2312 楷体_GB2312：KaiTi_GB2312 微软雅黑体：Microsoft YaHei
