      • deriveRange

        protected NumberRange<? extends Number> deriveRange​(NumberRange<? extends Number>[] ranges,
                                                            OperationJAI.Parameters parameters)
        Returns the expected range of values for the resulting image.
        deriveRange in class OperationJAI
        ranges - The range of values from every sources. For unary operations this array has a length of 1. For binary operations like "add" and "multiply", this array has a length of 2.
        parameters - Parameters, rendering hints and coordinate reference system to use.
        The range of values to use in the destination image, or null if unknow.
      • handleJAIEXTParams

        protected void handleJAIEXTParams​(ParameterBlockJAI parameters,
                                          ParameterValueGroup parameters2)
        Description copied from class: OperationJAI
        Extension point for adding to the JAI ParameterBlockJAI object the parameters defined in the ParameterValueGroup, which can be read by the JAI-EXT operations.

        Notice that if you are using JAI, the new parameters will not be accepted by the ParameterBlockJAI instance.

        handleJAIEXTParams in class OperationJAI
        parameters - ParameterBlockJAI instance used by the current JAI-EXT/JAI operation
        parameters2 - ParameterValueGroup instance containing input operation parameters

        Description copied from class: OperationJAI
        Prepares the properties to be given to the coverage created by the deriveGridCoverage method. The default implementation returns null.
