      j2d.hpp.LinearMappingProcessor

All Implemented Interfaces:

java.awt.image.ImageObserver

public class LinearMappingProcessor
extends ImageProcessor

This classes allows adjustment of the brightness (DC offset) and contrast (intensity stretch) of an image.

Method Detail

processImage

public void processImage()
                  throws java.lang.Exception

Implementation of ImageProcessor

Specified by:

processImage in class ImageProcessor

Throws:

java.lang.Exception

setParameters

public void setParameters(double offset,
                          double slope)

Set the processing parameters.

setOptimalParameters

public float[] setOptimalParameters()

Set offset and slope to maximize the use of the dynamic range. To apply the parameters to the image, this must be followed by a call to performAlgorithm().

Returns:

Two-element array. Element 0 contains the offset (brightness adjustment). Element 1 contains the slope (contrast adjustment).
