Function Documentation

void HLSTORGB	(	uchar &	hue,
		uchar &	lightness,
		uchar &	saturation
	)

Convert a color in HLS space to RGB space.

Parameters:

	hue	the hue component (modified in place).
	lightness	the lightness component (modified in place).
	saturation	the saturation component (modified in place).

Definition at line 385 of file gimp.h.

int HLSVALUE	(	double	n1,
		double	n2,
		double	hue
	)

Implement the HLS "double hex-cone".

Parameters:

Definition at line 238 of file gimp.h.

int INT_BLEND	(	int	a,
		int	b,
		int	alpha
	)			[inline]

Blend the two color components in the proportion alpha:

result = alpha a + ( 1 - alpha b)

Parameters:

	a	first component.
	b	second component.
