Method Detail

RGBAequals

public static boolean RGBAequals(float[] rgba1,
                                 float[] rgba2,
                                 float eps)

Checks if two colors differ within supplied epsilon. Colors must have length of at least 3. If only RGB is supplied, the alpha component is assumed to be one.

Parameters:

rgba1 - first color

rgba2 - second color

Returns:

true if any component differs by more than epsilon

interpolateColor

public static void interpolateColor(float[] result,
                                    float[] color0,
                                    float[] color1,
                                    double s)

Computes (1-s) color0 + s color1 and places the result in result. Only the first three array entries are used.

Parameters:

result - result value

color0 - first color

color1 - second color

s - interpolation parameter

HSVtoRGB

public static void HSVtoRGB(float[] hsv,
                            float[] rgb)

Convert an HSV color to RGB representation. It is assumed that all RBG and HSV values are in the range 0-1 (as opposed to the typical HSV ranges of [0-360], [0-100], [0-100]).

RGBtoHSV

public static void RGBtoHSV(float[] hsv,
                            float[] rgb)

Convert an RGB color to HSV representation. It is assumed that all RBG and HSV values are in the range 0-1 (as opposed to the typical HSV ranges of [0-360], [0-100], [0-100]).
