java.lang.Objectjavax.media.jai.OperationDescriptorImpl
javax.media.jai.operator.AbsoluteDescriptor
public class AbsoluteDescriptor
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).
