Class org.geotools.geometry.GeneralEnvelope

Examples of org.geotools.geometry.GeneralEnvelope.toRectangle2D()

org.geotools.geometry.GeneralEnvelope.toRectangle2D()
Returns a {@link Rectangle2D} with the same bounds as this {@code Envelope}. This is a convenience method for interoperability with Java2D. @return This envelope as a twp-dimensional rectangle. @throws IllegalStateException if this envelope is not two-dimensional.
