Examples of org.geotools.coverage.grid.GridGeometry2D.reduce()

org.geotools.coverage.grid.GridGeometry2D.reduce()

Reduces the specified envelope to a two-dimensional one. If the given envelope has more than two dimensions, then a new one is created using only the coordinates at ( {@link #axisDimensionX}, {@link #axisDimensionY}) index.

The {@link Envelope#getCoordinateReferenceSystem coordinate reference system} of thesource envelope is ignored. The coordinate reference system of the target envelope will be {@link #getCoordinateReferenceSystem2D} or {@code null}. @param envelope The envelope to reduce, or {@code null}. This envelope will not be modified. @return An envelope with exactly 2 dimensions, or {@code null} if {@code envelope} was null.The returned envelope is always a new instance, so it can be modified safely. @since 2.5
