java.lang.Object javax.media.jai.OperationDescriptorImpl javax.media.jai.operator.InvertDescriptor
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.
