Constructor Detail

Composite

public Composite(PointMapper pm1,
                 PointMapper pm2)

Create a composite of two PointMappers.

Parameters:

pm1 - the first PointMapper to be applied

pm2 - the pointMapper to applied last.

Method Detail

transform

public void transform(float[] x,
                      float[] y)
               throws IllegalArgumentException

Performs the Composite transforms. First pointMapper1 applies a transform on it, then pointMapper2 applies a transform on it.

Specified by:

transform in interface PointMapper

Parameters:

x - an array containing the x coordinates

y - an array containing the y coordinates

IllegalArgumentException

transform

public void transform(float[] x,
                      float[] y,
                      int offset,
                      int count)
               throws IllegalArgumentException

Performs the composite transforms.

Specified by:

transform in interface PointMapper

Parameters:

x - an array containing the x coordinates

y - an array containing the y coordinates

offset - the starting point of the array

count - the number of points from the offset to apply the transformation

IllegalArgumentException

inverseTransform

public void inverseTransform(float[] x,
                             float[] y)
                      throws IllegalArgumentException

Performs the inverse of the composite transforms.

Specified by:

inverseTransform in interface PointMapper

Parameters:

x - an array containing the x coordinates

y - an array containing the y coordinates

IllegalArgumentException

inverseTransform

public void inverseTransform(float[] x,
                             float[] y,
                             int offset,
                             int count)
                      throws IllegalArgumentException

Performs the inverse of the composite transforms.

Specified by:

inverseTransform in interface PointMapper

Parameters:

x - an array containing the x coordinates

y - an array containing the y coordinates

offset - the starting point of the array

count - the number of points from the offset to apply the transformation

IllegalArgumentException
