Class MonochromeTransformTosRGB

java.lang.Object

ucar.jpeg.icc.lut.MonochromeTransformTosRGB

public class MonochromeTransformTosRGB
extends Object

This class constructs a LookUpTableFP from a RestrictedICCProfile. The values in this table are used to calculate a second lookup table (simply a short []). table. When this transform is applied to an input DataBlk, an output data block is constructed by using the input samples as indices into the lookup table, whose values are used to populate the output DataBlk.
