Examples of org.geotools.gce.gtopo30.NoDataReplacerOpImage

org.geotools.gce.gtopo30.GTopo30Writer
An image that contains transformed samples, specifically this method will transform the NoData value using a new supplied one. A new layout is used in order to convert to the required image layout. Default values for this operation can be used to set the NoData and the layout to the values needed for the GTOPO30 writer. Images are created using the {@code NoDataReplacerOpImage.NoDataReplacerCRIF} inner class, where "CRIF" stands for{@link java.awt.image.renderable.ContextualRenderedImageFactory}. The image operation name is "org.geotools.gce.NoDataReplacer". @source $URL$ @version $Id$ @author Simone Giannecchini @since 2.2
