public class PaletteBox
This class is designed to represent a palette box for JPEG 2000 JP2 file format. A palette box has a length, and a fixed type of "pclr". Its content contains the number of palette entry, the number of color components, the bit depths of the output components, the LUT. Currently, only 8-bit color index is supported.
