| HeaderBox | | public class HeaderBox extends Box (Code) | | 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.
