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.
