ImageHeaderBox
public class ImageHeaderBox
This class is defined to represent an Image Header Box of JPEG JP2 file format. An Image Header Box has a length, and a fixed type of "ihdr". The content of an image header box contains the width/height, number of image components, the bit depth (coded with sign/unsign information), the compression type (7 for JP2 file), the flag to indicate the color space is known or not, and a flag to indicate whether the intellectual property information included in this file.
