C#在图片增加文字的实现代码

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
