Parameters:

dim - final dimension of the new coordinate

Method Detail

transform

public double[] transform(double[] coord)
                   throws IllegalCoordinateException

Add a fourth coordinate, to save a value.

Specified by:

transform in interface CoordinateOperation

transform in class AbstractCoordinateOperation

Parameters:

coord - is an array containing one, two or three ordinates

Returns:

a double array containing the output coordinate

Throws:

IllegalCoordinateException - if coord is not compatible with this CoordinateOperation.
