Converts from the RGB color space to HLS.
h, l, s = Ngl.rgbhls(r, g, b)
Argumentsr, g, b
Intensity values for red, green, and blue in the range [0.1.].
The hue of the input point in HLS color space, in the range [0.,360.). A value of (0.,0.,1.) in the input space will result in a hue of 0. in the output space.l
The lightness value of the input point in HLS color space in the range [0.,100.]. Lightness is a measure of the quantity of light - a lightness of 0. is black, and a lightness of 100. is white. The pure hues occur at lightness value 50.s
The saturation value of the input point in HLS color space in the range [0.,100.]. Saturation is a measure of how much white light is mixed with the color. Saturation values of 0. represent grays (with a gray value equal to the lightness value L). Saturation values of 100. are fully saturated colors. The hue is undefined when S=0. The fully saturated pure hues occur when S=100. and L=50. The saturation value should be thought of as a percentage.
This function converts from the RGB (Red, Green, Blue) color space to the HLS (Hue, Lightness, Saturation) color space.
