org.geotools.coverage.processing.Operations
Convenience, type-safe, methods for applying some common operations on {@linkplain Coverage coverage} objects. All methods wrap their arguments in a{@linkplain ParameterValueGroup parameter value group} and delegate the work to the processor's{@link CoverageProcessor#doOperation doOperation} method.This convenience class do not brings any new functionalities, but brings type-safety when the operation is know at compile time. For operation unknown at compile time (e.g. for an operation selected by users in some widget), use the {@linkplain CoverageProcessor processor} directly. @since 2.2 @source $URL$ @version $Id$ @author Martin Desruisseaux (IRD) @see org.geotools.coverage.processing.operation
