Class ColorSpecificationBox

java.lang.Object

com.sun.media.imageioimpl.plugins.jpeg2000.Box

com.sun.media.imageioimpl.plugins.jpeg2000.ColorSpecificationBox

public class ColorSpecificationBox
extends Box

This class is defined to represent a Color Specification Box of JPEG JP2 file format. A Channel Definition Box has a length, and a fixed type of "colr". Its content contains the method to define the color space, the precedence and approximation accuracy (0 for JP2 files), the enumerated color space, and the ICC color profile if any.
