public class: ByteLookupTable [javadoc | source]
java.lang.Object
   java.awt.image.LookupTable
      java.awt.image.ByteLookupTable
This class defines a lookup table object. The output of a lookup operation using an object of this class is interpreted as an unsigned byte quantity. The lookup table contains byte data arrays for one or more bands (or components) of an image, and it contains an offset which will be subtracted from the input values before indexing the arrays. This allows an array smaller than the native data size to be provided for a constrained input. If there is only one array in the lookup table, it will be applied to all bands.

Method from java.awt.image.ByteLookupTable Detail:
 public final byte[][] getTable() 
    Returns the lookup table data by reference. If this ByteLookupTable was constructed using a single byte array, the length of the returned array is one.
 public int[] lookupPixel(int[] src,
    int[] dst) 
    Returns an array of samples of a pixel, translated with the lookup table. The source and destination array can be the same array. Array dst is returned.
 public byte[] lookupPixel(byte[] src,
    byte[] dst) 
    Returns an array of samples of a pixel, translated with the lookup table. The source and destination array can be the same array. Array dst is returned.
