Can't save Images using QImage

Question

I wish to use QImage in Qt to load and save images. While I can load an image, for whatever reason it wont let me save the image.

So I started writing a simple code, made a simple png test file using paint, put it into the same folder as the project itself.

#include <QImage>
#include <iostream>

int main(){
    QImage image;
    image.load("test.png");

    if (image.isNull()){
        std::cout << "ERROR!\n";
    }
    else{
        std::cout << "IMAGE LOADED!\n";
    }

    image.save("test1.png");

    return 0;
}

During running the program I get the message of "IMAGE LOADED!" from the application output, however when I check the folder I expect the same image saved as test1.png, which doesn't appear at all.

So, how do I actually save an image? What did I miss?

Answer 1

In the other comments mentioned the image got saved into the working directory, which is not the same as the folder where the project is located.

In my specific case I got the image by adding a full path to the project like

int i = image.save("C:\\Users\\UserName\\Documents\\QT\\testing_ground_cpp\\" + string);

to find the image.

Ideally I should directly access with the working directory.
