Constructor Detail

CoordinateTransformation

public CoordinateTransformation(SpatialReference src,
                                SpatialReference dst)

Create transformation object.

Input spatial reference system objects are assigned by copy (calling clone() method) and no ownership transfer occurs.

Parameters:

src - source spatial reference system.

dst - target spatial reference system.

Method Detail

delete

public void delete()

Transform point from source to destination space.

Parameters:

x - input x value

y - input y value

Returns:

the transformed coordinates

Since:

Java bindings 1.7.0
