Question

I have this piece of code:

int main()
{
    string file = "stuff.jpg";

    Mat img = imread(file);
    if (img.empty())
    {
        printf("EMPTY");
        system("PAUSE");
        return -1;
    }
    imshow("display", img );

    waitKey(0);
    return 0;
}

When i launch this program in visual, i get that the img is empty, but if i run in from command line or by simply double clicking, it works fine. The path at the top when i run it in both visual and command line is the same. Why is that?

Answer 1

The working directory when run from visual studio is controlled by the project properties:

Configuration Properties | Debugging | Working Directory

Set that appropriately or specify a full, absolute path instead of just "stuff.jpg" for the filename.
