**Additional Information**


Additional options are available for reading or writing this format type, see
:doc:`options` for information.

There are two distinct versions of ND2: an old version, which uses 
JPEG-2000 compression, and a new version which is either uncompressed or 
Zip-compressed.  We are not aware of the version number or release date 
for either format. 

Bio-Formats uses the `JAI Image I/O Tools <https://github.com/jai-imageio/jai-imageio-core>`_ 
library to read ND2 files compressed with JPEG-2000.
