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
