Class AbstractStatisticsOperationJAI

Object
  AbstractOperation
      Operation2D
          OperationJAI
              AbstractStatisticsOperationJAI

All Implemented Interfaces:

Serializable, Operation

Direct Known Subclasses:

Extrema, Histogram, ZonalStats

public abstract class AbstractStatisticsOperationJAI
extends OperationJAI

This class is the root class for the Statistics operations based on JAI's StatisticsOpImage like Extrema and Histogram. It provides basic capabilities for management of geospatial parameters like ROIs and subsampling factors.

Since:

2.4.x

Constructor Detail

AbstractStatisticsOperationJAI

public AbstractStatisticsOperationJAI(OperationDescriptor operationDescriptor)

Constructor for AbstractStatisticsOperationJAI.

Parameters:

operationDescriptor - OperationDescriptor for the underlying JAI operation.

AbstractStatisticsOperationJAI

public AbstractStatisticsOperationJAI(OperationDescriptor operationDescriptor,
                                      ImagingParameterDescriptors replacements)

Constructor for AbstractStatisticsOperationJAI.

Parameters:

operationDescriptor - OperationDescriptor for the underlying JAI operation.

replacements - ImagingParameterDescriptors that should replace the correspondent ImagingParameters in order to change the default behavior they have inside JAI.

AbstractStatisticsOperationJAI

public AbstractStatisticsOperationJAI(String name)

Constructor for AbstractStatisticsOperationJAI.

Parameters:

name - of the underlying JAI operation.

Method Detail

prepareParameters

protected ParameterBlockJAI prepareParameters(ParameterValueGroup parameters)

Copies parameter values from the specified ParameterValueGroup to the ParameterBlockJAI

Overrides:

prepareParameters in class OperationJAI

Parameters:

parameters - The ParameterValueGroup to be copied.

Returns:

A copy of the provided ParameterValueGroup as a JAI block.
