How can I crop an image in Qt?

I load a PNG image in a QPixmap/QImage and I want to crop it. Is there a function that does that in Qt, or how should I do it otherwise?

Solution

  • You can use QPixmap::copy:

    QRect rect(10, 20, 30, 40);
QPixmap original('image.png');
QPixmap cropped = original.copy(rect);

    There is also QImage::copy:

    QRect rect(10, 20, 30, 40);
QImage original('image.png');
QImage cropped = original.copy(rect);
