    Default 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:

    Qt Code:
    1. #include "mainwindow.h"
    2.  
    3. #include <QApplication>
    4.  
    5. int main(int argc, char *argv[])
    6. {
    7. QApplication a(argc, argv);
    8. MainWindow w;
    9. QImage test;
    10. test.load("C:/IMAGES/IMAGE.png"); // crashes program
    11. w.show();
    12. return a.exec();
    13. }
    To copy to clipboard, switch view to plain text mode 

    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.

    Default Re: Error when Loading QImage

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