I want to create a png image with transparency.
QImage image(dim, dim, QImage;;Format_ARGB32);
and I set the
qRgba(qRed, qGreen, qBlue, alpha)
But the alpha channel does not modify the transparency/opacity of the color, instead modify the intensity color (from white to color).
Thus, how can I set the transparency of the QImage (which I save on file)?
I have to use QImage, no other stuff.
