mfc使用opencv时CImage(CvvImage)取消以后的替代方法及error C2039: “DrawToHDC”: 不是“ATL::CImage”的成员

由于OpenCV2.2里面，把原来的CvvImage整个类给删除掉了，因此在MFC下使用带来诸多不方便，大家可以通过提前opencv2.1中的代码的方法来解决（弄一个h文件和一个cpp文件，然后放到你的项目里面一起编译就可以了）。

但是在s2010中会出现error C2039: “DrawToHDC”: 不是“ATL::CImage”的成员的错误。

这主要是因为命名冲突引起的，引入命名空间可以解决。

将CvvImage.h的倒数第二句改成：

namespace cv
{
typedef CvvImage CImage;
}

在使用CImage之前包含CcvImage.h并且将CImage写成cv::CImage即可。

当然最简单的办法还是将CImage直接换成CvvImage

接下来的是从老版本来的源文件，已配置的可以略过.
