How to generate a pixmap with some text superimposed on a thumbnaill image ?

[Lykurg]

You can use QPainter on a pixmap and draw everything you like on it.

How do I prevent the original pixmap from getting modified & save the modified image to a new pixmap ?

QPixmap original = //...
QPixmap pixWithText = original;
QPainter p(&pixWithText);
//..
pixWithText.save();

QPixmap original = //...
QPixmap pixWithText = original;
QPainter p(&pixWithText);
//..
pixWithText.save();

To copy to clipboard, switch view to plain text mode
