WKTWriter.withDimension constructor
WKTWriter.withDimension(
- int outputDimension
Creates a writer that writes {@link Geometry}s with the given output dimension (2 to 4). The output follows the following rules:
- If the specified output dimension is 3 and the z is measure flag
is set to true, the Z value of coordinates will be written if it is present
(i.e. if it is not
Double.NaN
) - If the specified output dimension is 3 and the z is measure flag
is set to false, the Measure value of coordinates will be written if it is present
(i.e. if it is not
Double.NaN
) - If the specified output dimension is 4, the Z value of coordinates will
be written even if it is not present when the Measure value is present.The Measrue
value of coordinates will be written if it is present
(i.e. if it is not
Double.NaN
)
@param outputDimension the coordinate dimension to output (2 to 4)
