How can I check HSV value of pixel?

Question

I want to read HSV value of pixel. I wrote that code, but it is probably wrong. Can you help me with that? Thanks a lot and have a nice day!

img = new QImage(600,600,QImage::Format_RGB32);
img -> load("D:/1.jpg");
bits = img->bits();

int h = bits[0].hue();
int s = bits[1].saturation();
int v = bits[2].value();

Answer 1

transform to QColor and use .toHsv

QColor color(bits[0],bits[1],bits[2]);
color.toHsv();
