Method Detail

inputCoordinateSystem

public CoordinateSystemI inputCoordinateSystem()

Returns the coordinate system used by the input.

outputCoordinateSystem

public CoordinateSystemI outputCoordinateSystem()

Returns the coordinate system used by the output.

forwardTransform

public PointI forwardTransform(PointI point)
                        throws GeomException

Returns a transformed point. Converts from the input coordinate system to the output coordinate system.

inverseTransform

public PointI inverseTransform(PointI point)
                        throws GeomException

Returns an inverse transformed point. Converts from the output coordinate system to the input coordinate system.

forwardTransform

public RangeI forwardTransform(RangeI range)
                        throws GeomException

Returns a transformed range. Converts from the input coordinate system to the output coordinate system.

inverseTransform

public RangeI inverseTransform(RangeI range)
                        throws GeomException

Returns an inverse transformed range. Converts from the output coordinate system to the input coordinate system.
