public class SignatureBox
extends BaseJP2KBox

This class is defined to represent a Signature Box of JPEG JP2 file format. This type of box has a fixed length of 12, a type of "jP " and a four byte content of 0x0D0A870A, which is used to detects of the common file transmission errors which substitutes with or vice versa.

It must be the first box in a JP2 file.
