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：

 1             string path = @"E:cover.png";
 2 
 3             Bitmap bmp = new Bitmap(path);
 4             Graphics g = Graphics.FromImage(bmp);
 5             String str = "贤愚经";
 6             Font font = new Font("仿宋_GB2312", 14, FontStyle.Bold);//设置字体，大小，粗细
 7             SolidBrush sbrush = new SolidBrush(Color.White);//设置颜色
 8             int base_left = 10;
 9             int left_space = 30;
10 
11             int base_top = 27;
12             int top_space = 27;
13             for (int i = 0; i < str.Length; i++)
14             {
15                 if (i > 13)
16                 {
17                     continue;
18                     g.DrawString(str[i] + "", font, sbrush, new PointF(base_left + (left_space * 2), base_top + (top_space * (i - 14))));
19                 }
20                 else if (i > 6)
21                 {
22                     g.DrawString(str[i] + "", font, sbrush, new PointF(base_left + (left_space * 1), base_top + (top_space * (i - 7))));
23                 }
24                 else
25                 {
26                     g.DrawString(str[i] + "", font, sbrush, new PointF(base_left, base_top + (top_space * i)));
27                 }
28 
29             }
30 
31             //MemoryStream ms = new MemoryStream();
32             //bmp.Save(ms, System.Drawing.Imaging.ImageFormat.Bmp);
33             bmp.Save(@"E:cover1.png");
