HSL2RGB

public static Color HSL2RGB(double h,
 double s,
 double l,
 double alpha)

Convert HSL values to a RGB Color.

Parameters:

h - Hue is specified as degrees in the range 0 - 360.

s - Saturation is specified as a percentage in the range 1 - 100.

l - Luminance is specified as a percentage in the range 1 - 100.

alpha - the alpha value between 0 - 1

Returns:

the RGB Color object

public static double[] RGB2HSL(Color color)

Convert a RGB Color to it corresponding HSL values.

Returns:

an array containing the 3 HSL values.

RGB2SCRGB

public static double[] RGB2SCRGB(Color color)

Convert sRGB Color to scRGB [0..1] (0:red,1:green,2:blue). Alpha needs to be handled separately.
