- All Implemented Interfaces:
- OperationDescriptor, RegistryElementDescriptor, Serializable
- public class InvertDescriptor
- extends OperationDescriptorImpl
An OperationDescriptor describing the "Invert" operation.
The "Invert" operation inverts the pixel values of an image.
For source images with signed data types, the pixel values of the
destination image are defined by the pseudocode:
dst[x][y][b] = -src[x][y][b]
For unsigned data types, the destination values are defined by:
dst[x][y][b] = MAX_VALUE - src[x][y][b]
where MAX_VALUE is the maximum value supported by the
system of the data type of the source pixel.
