Error when Loading QImage

My program crashes when I try to load an image from my computer into a QImage. I made sure that the path to the file is correct and tried to make a QImage pointer, but it still results in an error. This was originally part of a larger program, but even in this simple recreation, it doesn't work.

Here is my code in main.cpp:

Code:

---

#include "mainwindow.h"
 
#include <QApplication>
 
int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    MainWindow w;
    QImage test;
    test.load("C:/IMAGES/IMAGE.png"); // crashes program
    w.show();
    return a.exec();
}

Here is the error received when I used the debugger:

qt.gui.imageio: libpng warning: iCCP: known incorrect sRGB profile
HEAP[sdf.exe]:
Invalid address specified to RtlFreeHeap( 00000000000D0000, 0000000000DF7240 )

There are also no changes in mainwindow.cpp and the header file, but I added "CONFIG += console" to the .pro file.

Hi, is the image a valid .png file? How large is it? Have you tried other .png files?

The error you are getting may be due to the Qt platform lacking a plugin for the format you are trying to use, or the image path may be incorrect or the image may be corrupted. Check for file path errors.

PNG format support is built in to Qt; it does not require a plugin. And since the OP's example provides an absolute path to the image file, a path error is probably not the cause. I would suspect a corrupted image.
