Function Documentation

template<class T>

void vil1_colour_space_HSV_to_RGB	(	T	h,
		T	s,
		T	v,
		T *	r,
		T *	g,
		T *	b
	)

Transform from HSV to RGB colour space.

The input HSV values will lie in the ranges: H : [0, 360) (an angle, in bloody degrees) S : [0, 1] V : [0, 255]

The output RGB values will lie in [0, 255]

[HSV is also known as HSB]

template<class T>

void vil1_colour_space_RGB_to_HSV	(	T	r,
		T	g,
		T	b,
		T *	h,
		T *	s,
		T *	v
	)

Transform from RGB to HSV colour spaces.

The input RGB values must lie in [0, L], for some positive L. Usually L=1 or 255.

The output HSV values will lie in the ranges: H : [0, 360) (an angle, in bloody degrees) S : [0, 1] V : [0, L]

[HSV is also known as HSB]
