Examples of org.opengis.coverage.grid.GridEnvelope

org.opengis.coverage.grid.GridEnvelope
Provides the {@linkplain GridCoordinates grid coordinate} values for the diametrically opposedcorners of the {@linkplain Grid grid}.
Remark that both corners are inclusive. Thus the number of elements in the direction of the first axis is {@linkplain #getHigh(int) getHigh}(0) - {@linkplain #getLow(int) getLow}(0) + 1. This is the opposite of Java2D usage where maximal values in {@link Rectangle} (as computed by{@linkplain Rectangle#getMaxX getMaxX()} and {@linkplain Rectangle#getMinY getMaxY()}) are exclusive. @source $URL$ @version ISO 19123:2004 @author Wim Koolhoven @author Martin Schouwenburg @since GeoAPI 2.1 @see org.opengis.geometry.Envelope
