◆ ToHSV()

void COLOR4D::ToHSV	(	double &	aOutHue,
		double &	aOutSaturation,

	)		const

Convert current color (stored in RGB) to HSV format.

Parameters

aOutHue	is the conversion result for hue component, in degrees 0 ... 360.0.
aOutSaturation	is the conversion result for saturation component (0 ... 1.0).
aOutValue	is conversion result for value component (0 ... 1.0).
aAlwaysDefineHue	controls the way hue is defined when r = v = b

Note: saturation is set to 0.0 for black color (r = v = b = 0), and if r = v = b, hue is set to 0.0 if aAlwaysDefineHue = true, and set to NAN if aAlwaysDefineHue = false. this option is useful to convert a 4D color to a legacy color, because Red has hue = 0, therefore aAlwaysDefineHue = false makes difference between Red and Gray colors.
