This is one way to convert QPixmap to QByteArray.
Useful when you want to store a pixmap in a database etc.
QPixmap pixmap;
// Preparation of our QPixmap
QByteArray bArray;
QBuffer buffer(&bArray);
buffer.open(QIODevice::WriteOnly);
pixmap.save(&buffer, "PNG");
Now variable bArray contains the byte array form of pixmap.
