Examples of org.geotools.coverage.grid.GeneralGridEnvelope

org.geotools.coverage.grid.GeneralGridEnvelope
Defines a range of grid coverage coordinates.
CAUTION: ISO 19123 defines {@linkplain #getHigh high} coordinates as inclusive.We follow this specification for all getters methods, but keep in mind that this is the opposite of Java2D usage where {@link Rectangle} maximal values are exclusive. When thecontext is ambiguous, an explicit {@code isHighIncluded} argument is required. @since 2.5 @source $URL$ @version $Id$ @author Martin Desruisseaux (IRD) @see GridEnvelope2D
