Constructor Detail

BilevelOperation

public BilevelOperation(String name)
                 throws OperationNotFoundException

Constructs a bilevel operation with an OGC's name identical to the JAI name.

Parameters:

name - The JAI operation name.

Throws:

OperationNotFoundException - if no JAI descriptor was found for the given name.

Method Detail

deriveSampleDimension

protected GridSampleDimension[] deriveSampleDimension(GridSampleDimension[][] bandLists,
                                                      OperationJAI.Parameters parameters)

Derives the GridSampleDimensions for the destination image.

Overrides:

deriveSampleDimension in class OperationJAI

Parameters:

bandLists - Sample dimensions for each band in each source coverages.

parameters - The user-supplied parameters.

Returns:

The sample dimensions for each band in the destination image.
