Можно ли задать для QLabel два QImages

QLabel, QImage

Добрый день.
Можно ли задать для QLabel 2 QImages (один с картинкой, второй прозрачный) и рисовать на прозрачном QImage?

Похоже нужно создать класс наследник.
Может быть вы знаете, как задать set2Images?

#ifndef QLABEL2IMAGES_H
#define QLABEL2IMAGES_H
#include "QLabel"


class QLabel2Images : public QLabel 
{
public:
    QLabel2Images();
    ~QLabel2Images();
    void set2Images(QImage &downImage, QImage &yopImage);
};

#endif // QLABEL2IMAGES_H

    Использовал пример от Qt .
    Сделал так в конструкторе:

        //задание 2 картинок на QLabel
        //нижняя картинка
        QImage mapImage(":/Images/Images/mapMain.png");
        myImageViewer->setImage(mapImage);    
        QImage base(":/Images/Images/mapMain.png"); // set to some file/size
        //верхняя картинка
        QImage overlay(":/Images/Images/mapTop.png");  // set to some file/size
        QPainter paint(&base);
        paint.drawImage(0,0,overlay);
        myImageViewer->imageLabel->setPixmap(QPixmap::fromImage(base));
        ui->verticalLayout->addWidget(myImageViewer);
