c++ cli && mfc ---opencv 读取图片并显示

const char* imagename = "c:\\cctv.jpg"; 
cv::Mat img = cv::imread(imagename); // Matlab风格的 cvLoadImage 函数的另一种调用
//cv::namedWindow("image", CV_WINDOW_AUTOSIZE); //创建窗口
//cv::imshow("image", img); //显示图像
//IplImage* img = cvLoadImage(imagename, -1);//读入图片
IplImage img2 = IplImage(img);
CvvImage cvvImg;
cvvImg.CopyOf(&img2, 3);

//Control ^ ct = Control::FromHandle(pic_show->Handle);
//IntPtr dc = GetDC()
