    Re: Qt camera swaping colors

    Here's something:
    Qt Mobility camera functions do not help here. You need to load the image into a QImage and then go through all pixels. Get their colour values into a QColor variable (QRgb pixel = image.pixel(x, y) and replace the pixel value swapping the color channels, for example image.setPixel(x, y, QRgb(pixel.qRed(), pixel.qBlue(), pixel.qGreen())).
