Jpeg2000 Tags

The tags below are found in JPEG 2000 images and the JUMBF metadata in JPEG images, but not all of these are extracted. Note that ExifTool currently writes only EXIF, IPTC and XMP tags in Jpeg2000 images.

This is a List-type tag because multiple XML blocks may exist) --> XMP XML Tags (used for XMP in JPEG XL files) --> XMP Tags

Jpeg2000 ColorSpec Tags

The table below contains tags in the color specification (colr) box. This box may be rewritten by writing either ICC_Profile, ColorSpace or ColorSpecData. When writing, any existing colr boxes are replaced with the newly created colr box.

NOTE: Care must be taken when writing this color specification because writing a specification that is incompatible with the image data may make the image undisplayable.
