The output of a 0N/A * lookup operation using an object of this class is interpreted 0N/A * as an unsigned byte quantity. The lookup table contains byte 0N/A * data arrays for one or more bands (or components) of an image, 0N/A * and it contains an offset which will be subtracted from the 0N/A * input values before indexing the arrays. This allows an array 0N/A * smaller than the native data size to be provided for a 0N/A * constrained input. If there is only one array in the lookup 0N/A * table, it will be applied to all bands. 0N/A * @see ShortLookupTable 0N/A * Constructs a ByteLookupTable object from an array of byte 0N/A * arrays representing a lookup table for each 0N/A * band.
