opencv - c++ cvShowImage 错误

Question

我想用opencv加载图像。一切正常，但没有显示图像。我使用的代码在这里：#include #include #include

 using namespace cv;
 using namespace std;

 int main( int argc, const char** argv )
 {
     IplImage *img = cvLoadImage("D:/C++/ MGC.JPG");

     cvNamedWindow("MyWindow", 1); //create a window with the name "MyWindow"
     cvMoveWindow("MyWindow", 100, 100);
     cvShowImage("MyWindow", img);

     cvWaitKey(0); //wait infinite time for a keypress
     cvDestroyWindow("MyWindow"); //destroy the window with the name, "MyWindow"

     return 0;
 }

Answer 1

您选择使用 C 接口是否有特定原因？如果没有，您应该使用 C++ 接口

int main( int argc, const char** argv )
{
    cv::Mat image = cv::imread("D:/C++/ MGC.JPG");
    cv::namedWindow("MyWindow", 256);
    cv::imshow("MyWindow", image );
    cv::waitKey();
    return 0;
}
