Examples of org.geotools.coverage.grid.GridCoverageFactory.create()

org.geotools.coverage.grid.GridCoverageFactory.create()
Constructs a grid coverage from an {@linkplain ImageFunction image function}. @param name The grid coverage name. @param function The image function. @param gridGeometry The grid geometry. The {@linkplain GridGeometry2D#getGridRange gridrange} must contains the expected image size (width and height). @param bands Sample dimensions for each image band, or {@code null} fordefault sample dimensions. @param properties The set of properties for this coverage, or {@code null} if there is none. @return The new grid coverage. @since 2.2
