Converts from the RGB color space to HSV.
h, s, v = Ngl.rgbhsv(r, g, b)
Argumentsr, g, b
Intensity values for red, green, and blue in the range [0.1.].
Represents the hue of the input point in HSV color space. A value of (R,0.,0.) in the input space will result in a hue of 0. in the output space.s
The saturation value of the input point in HSV color space, in the range [0.,1.]. 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 V). Saturation values of 1. are fully saturated colors. The hue is technically undefined when S=0.; the code leaves H at its previous value when S=0. (0. initially). The fully saturated pure hues occur when S=1. and V=1.v
The value in HSV space, in the range [0.,1.].
This function converts from the RGB (Red, Green, Blue) color space to the HSV (Hue, Saturation, Value) color space.
