Method Detail

RGBToHSV

@Implementation
public static void RGBToHSV(int red,
                                            int green,
                                            int blue,
                                            float[] hsv)

This is implemented in native code in the Android SDK.

Since HSV == HSB then the implementation from java.awt.Color can be used, with a small adjustment to the representation of the hue.

java.awt.Color represents hue as 0..1 (where 1 == 100% == 360 degrees), while Color represents hue as 0..360 degrees. The correct hue can be calculated by multiplying with 360.

Parameters:

red - Red component

green - Green component

blue - Blue component

hsv - Array to store HSV components
