Field Detail

redFunction

private final AnimationFunction<java.lang.Integer> redFunction

Refers to an AnimationFunction of float values that maps a time to the red component of an sRGB color value.

greenFunction

private final AnimationFunction<java.lang.Integer> greenFunction

Refers to an AnimationFunction of float values that maps a time to the green component of an sRGB color value.

blueFunction

private final AnimationFunction<java.lang.Integer> blueFunction

Refers to an AnimationFunction of float values that maps a time to the blue component of an sRGB color value.

Constructor Detail

ColorFunction

private ColorFunction(long duration,
                      java.awt.Color[] colors,
                      float[] keyTimes)

Creates an AnimationFunction that maps times to instances of Color. The mapping is interpolated from an array of Colors using an array of key times.

Parameters:

duration - the duration of this animation function

colors - the colors to interpolate.

keyTimes - an array of key times used to distribute the result values over the time.

Method Detail

valueAt

public java.awt.Color valueAt(long time)

Returns the interpolated color for a given time in the valid time interval.

Parameters:

time - the time used to determine the interpolated color

Returns:

the interpolated color for the given time
