在windows编程中，很多图片信息，都是基于windows系统所谓的DIB（设备无关位图）的结构，其定义在结构体 BITMAPINFOHEADER 中。本方法可以讲 windows 定义的DIB 结构和Opencv内部定义的IPLImage结构做相互转化。 -In windows programming, lots of pictures of information, are based on the windows system called DIB (device-independent bitmap) structure, which is defined in the BITMAPINFOHEADER structure. This method can tell windows DIB defined within the definition of the structure and Opencv do IPLImage structure into each other.
