Rippler.AxisConfig

public Rippler.AxisConfig(double start,
                          double length,
                          double amplitude)

Constructor.

Parameters:

start - the starting x offset to generate wave values. Should be between 0 and 2 * Math.PI.

length - the length of x to be used to generate wave values. Should be between 0 and 4 * Math.PI.

amplitude - the maximum y value, if it is too big, some important parts of the image (like the text) can "wave" out on the top or on the bottom of the image.

normalize

protected double normalize(double a,
                           int multi)

Normalizes parameter to fall into [0, multi * Math.PI].

Parameters:

a - to be normalized

multi - multiplicator used for end value

Returns:

normalized value

getStart

public double getStart()

Returns:

wave part start value

getLength

public double getLength()

Returns:

wave part length

getAmplitude

public double getAmplitude()

Returns:

amplitude used to transform the wave part
