记录-C#给图片增加文字

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");
