**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 `_
library to read ND2 files compressed with JPEG-2000.
There is also a **legacy** ND2 reader that uses Nikon's native libraries.
To use it, you must be using Windows 32-bit and have `Nikon's ND2 reader plugin for ImageJ
`_ installed.
Additionally, you will need to download :source:`LegacyND2Reader.dll
`
and place it in your ImageJ plugin folder.
Note that this reader is **unmaintained** and no additional support effort
will be made.
