Jpeg2000 Tags

The tags below are extracted from JPEG 2000 images and the JUMBF metadata in JPEG images. Note that ExifTool currently writes only EXIF, IPTC and XMP tags in Jpeg2000 images.

(by default, data in this tag is parsed using the ExifTool JSON module to to allow individual tags to be accessed when reading, but it may also be extracted as a block via the "JSONData" tag or by setting the API BlockExtract option)

(by default, the XML data in this tag is parsed using the ExifTool XMP module to to allow individual tags to be accessed when reading, but it may also be extracted as a block via the "XML" tag, which is also how this tag is written and copied. It may also be extracted as a block by setting the API BlockExtract option. This is a List-type tag because multiple XML blocks may exist)
