Revision history [back]

OpenCV version: 4.0.1
IDE: Visual Studio 2017

I took code from https://docs.opencv.org/4.0.1/db/deb/tutorial_display_image.html
Here is the project Debug folder, it has the logo file.png and test.jpg

The application is compiled in debug folder.

But when I try to run the application and display one of the images in the application folder, the application writes that imread cannot open the image.

Please help.

EDIT:

This code shows whether the file is available before imread starts opening it.

#include <opencv2/core.hpp>
#include <opencv2/imgcodecs.hpp>
#include <opencv2/highgui.hpp>
#include <fstream>
#include <iostream>
#include <string>
using namespace cv;
using namespace std;
int main(int argc, char** argv)
{
    String imageName("C:\\Users\\Emilia\\Desktop\\VS\\imageFolder\\image.jpg"); // by default
    ifstream input(imageName);
    if (input)
    {
        if (input)
        {
            cout << "Ok! file exists...\n";
        }
        else
        {
            cout << "Oops! file not exists...\n";
            return -1;
        }
    }
    input.close(); //close file
    Mat image;
    image = imread(imageName, IMREAD_COLOR); // Read the file
    if (image.empty())                      // Check for invalid input
    {
        cout << "Could not open or find the image" << std::endl;
        return -1;
    }
    namedWindow("Display window", WINDOW_AUTOSIZE); // Create a window for display.
    imshow("Display window", image);                // Show our image inside it.
    waitKey(0); // Wait for a keystroke in the window
    return 0;
}

Here's what the program shows
