Method Detail

HLStoRGB

public static int HLStoRGB(float hue,
                           float light,
                           float sat)

HLStoRGB3

public static int HLStoRGB3(float hue,
                            float light,
                            float sat)

Converts a color given by hue, light and sat to rgb.

Parameters:

hue - The color in range 0..24.0. 0 is magenta, 4: red, 8 yellow, 12 green 16 cyan, 20 blue, 24 magenta.

light - The light, 0 to 2.0. 1.0 is the saturated red 0xff0000 or a darker yellow. 1.4 is yellow 0xffff00. till 2.0 it uses the base values for color in white direction. 2.0 it is white.

sat - Saturation 0..1. part of gray. 1.0 is non-gray. 0 is full gray.

Returns:

rgb
