RGB QColor(QRgb)

[yogeshgokul]

You have to manually map the values from.
0..........1

On

0..........255

Then pass the mapped value in qRgba(); I am not good in Mathematics otherwise could have provide you the actual solution.

If you just want to create a QColor from rgb values between 0 and 1, you can also use QColor::setRgbF(). No need to think about

(quint8)(value*255)

(quint8)(value*255)

To copy to clipboard, switch view to plain text mode 

and polluting your code with it.
