Class org.geotools.geometry.jts.ReferencedEnvelope

Examples of org.geotools.geometry.jts.ReferencedEnvelope.transform()

org.geotools.geometry.jts.ReferencedEnvelope.transform()
Transforms the referenced envelope to the specified coordinate reference system.
This method can handle the case where the envelope contains the North or South pole, or when it cross the ±180ï¿½ longitude. @param targetCRS The target coordinate reference system. @param lenient {@code true} if datum shift should be applied even if there isinsuffisient information. Otherwise (if {@code false}), an exception is thrown in such case. @return The transformed envelope. @throws FactoryException if the math transform can't be determined. @throws TransformException if at least one coordinate can't be transformed. @see CRS#transform(CoordinateOperation,org.opengis.geometry.Envelope)
