javax.media.jai.operator.AbsoluteDescriptor
| AbsoluteDescriptor | | public class AbsoluteDescriptor extends OperationDescriptorImpl (Code) | | 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).
