http://iecapt.sourceforge.net/
http://cutycapt.sourceforge.net/

### 操作代码
1.以管理员身份 运行cmd.exe

切换到 IECapt.exe  所在目录
例如：
输入：D:
输入：cd  D:\AppData\
输入截图命令：
输入：CutyCapt  --url=https://tieba.baidu.com/p/5217647622 --out=D:/1.jpeg --silent
输入：iecapt  --url=https://tieba.baidu.com/p/5217647622 --out=D:/1.jpeg --silent
看下D:盘目录下是否存在
