public class JAIBandCombine
extends Transformer

Linearly combines input bands into an output image. The matrix parameter specifies how many input bands there are, and how many output bands there will be. The width of the matrix is equal to the number of input bands plus one. The last column is used for offsetting. The number of rows in the matrix dictates how many bands there are in the output image. For example, to swap the second and third bands in a three banded image, the following matrix can be used:

 1 0 0 0
 0 0 1 0
 0 1 0 0

Field Detail

matrix

public Parameter matrix
The transformation matrix. The entries in this matrix should doubles. The default matrix passes each band with no offsetting.


_initialMatrix

private double[][] _initialMatrix
The initial value of the transformation matrix.


_matrixValue

private double[][] _matrixValue
The value of the transformation matrix

Constructor Detail

JAIBandCombine

public JAIBandCombine(CompositeEntity container,
                      java.lang.String name)
               throws IllegalActionException,
                      NameDuplicationException
Construct an actor with the given container and name.

Parameters:
container - The container.
name - The name of this actor.
Throws:
IllegalActionException - If the actor cannot be contained by the proposed container.
NameDuplicationException - If the container already has an actor with this name.
Method Detail
