JP2 is the baseline image file format defined by the JPEG 2000 standard. It encapsulates a JPEG 2000 codestream.

Contents

Identification

JP2 files begin with bytes 00 00 00 0c 6a 50 20 20 0d 0a 87 0a ?? ?? ?? ?? 66 74 79 70 6a 70 32 20.

However, if four bytes at offset 20 are not as shown above ("jp2 "), a JP2 decoder is still expected to decode the file if "jp2 " appears in the list beginning at byte offset 28.
