Class RangeLookupOpImage

Object

PlanarImage

OpImage

PointOpImage

RangeLookupOpImage

All Implemented Interfaces:

RenderedImage, ImageImageN, PropertyChangeEmitter, PropertySource, WritablePropertySource

public class RangeLookupOpImage
extends PointOpImage

This is a variation on the ImageN org.eclipse.imagen.LookupDescriptor. It works with a RangeLookupTable object in which each entry maps a source image value range to a destination image value. Optional ROIs may be used in computations.

Constructor Details

RangeLookupOpImage

public RangeLookupOpImage(RenderedImage source,
 Map config,
 ImageLayout layout,
 RangeLookupTable table,
 Number defaultValue,
 ROI roi)

Constructor

Parameters:

source - a RenderedImage.

config - configurable attributes of the image

layout - an ImageLayout optionally containing the tile grid layout, SampleModel, and ColorModel, or null.

table - an instance of RangeLookupTable that defines the mappings from source value ranges to destination values

defaultValue - either a value to use for all unmatched source values or null to indicate that unmatched values should pass-through to the destination

roi - ROI object used for masking image areas.
