| AutoRescaleDescriptor | | public class AutoRescaleDescriptor extends OperationDescriptorImpl (Code) | | Class
AutoRescaleDescriptor is an
OperationDescriptor describing the autorescale operation. This operation is a
simplification of the rescale operator such that the calculation of
the offsets and the constants are made from a range of values.
The autorescale operation takes two parameters, the lower bounds and
the upper bands of the range.
If a band of the image is constant, that is all the values are the same, the
new values of said band will be (upperbounds - lowerbounds) / 2.
