Constructor Detail

OffsetTransformation

public OffsetTransformation(double dx,
                            double dy)

Creates a new instance of the transformation.

Parameters:

dx - the translation to apply to the longitude.

dy - the translation to apply to the latitude.

OffsetTransformation

public OffsetTransformation(Point offset)

Creates a new instance of the transformation.

Parameters:

offset - the translation to apply to the longitude and the latitude.

Method Detail

getDx

public double getDx()

Returns the translation to apply to the longitude.

Returns:

the value of the translation.

getDy

public double getDy()

Returns the translation to apply to the latitude.

Returns:

the value of the translation.

transform

public Geometry transform(Point point)

Translate the specified coordinate with the specified translation values specified at the transformation creation.

Parameters:

point - the coordinate to translate.

Returns:

the translated point. The returned instance is always the same instance as point that was specified in parameter.

clone

public java.lang.Object clone()

Clones the current transformation.

Specified by:

clone in interface Transformation

Specified by:

clone in class UnaryTransformation

Returns:

a new transformation instance initialized with the same translation values than the current one.
