- All Implemented Interfaces:
- org.opengis.coverage.processing.Operation, java.io.Serializable
- public class Invert
- extends OperationJAI
Inverts the sample values of a coverage. For source coverages with signed data types,
the sample values of the destination coverage are defined by the pseudocode:
dst[x][y][b] = -src[x][y][b]
Name: "Invert"
JAI operator: "Invert"
