All Implemented Interfaces:

public class AbsoluteDescriptor

extends OperationDescriptorImpl

An OperationDescriptor describing the "Absolute" operation.

The "Absolute" operation takes a single rendered or renderable source image, and computes the mathematical absolute value of each pixel:

 if (src[x][y][b] < 0) {
     dst[x][y][b] = -src[x][y][b];
 } else {
     dst[x][y][b] =  src[x][y][b];
 }
 

For signed integral data types, the smallest value of the data type does not have a positive counterpart; such values will be left unchanged. This behavior parallels that of the Java unary minus operator (see The Java Language Specification, section 15.14.4).
