MFC中将图片显示到picture控件上

在实现以下代码之前需要首先加载CvvImage.cpp和CvvImage.h两个文件

void CPicProcessDlg::DrawImgToHDC(Mat &img, UINT ID)
{
CDC *pDC = GetDlgItem(ID)->GetDC();
HDC hDC = pDC->GetSafeHdc();
CRect rect;
GetDlgItem(ID)->GetClientRect(&rect);
CvvImage Cimg;
IplImage Ipimg = img;
Cimg.CopyOf(&Ipimg, 3);
Cimg.DrawToHDC(hDC, &rect);
ReleaseDC(pDC);
}
