+#### Plugin ID `32033`
+
+[High Throughput JPEG 2000 (HTJ2K)](https://jpeg.org/jpeg2000/htj2k.html) is an addition to the JPEG 2000 family of International Standards developed by JPEG Committee (ISO/IEC JTC 1/SC 29/WG 1).
+HTJ2K brings an order of magnitude increase in throughput to JPEG 2000 at the expense of slightly reduced coding efficiency.
+Plugin features:
+
+* Bare high-throughput JPEG2000 codestream.
+* Lossless compression only. For lossy compression use an HTJ2K library and write the chunk directly with `H5Dwrite_chunk`.
+* Limited support of datatypes to ensure different HTJ2K libraries can read the chunks: `int8`, `uint8`, `int16`, `uint16`.
+* Chunk shapes with at most 3 non-unity dimensions.
+* Limited JPEG2000 "components" support: For chunks with 3 non-unity dimensions, the last non-unity dimension must be 3.
+* Not limited to a particular HTJ2K implementation.
+
+Plugin's `cd_values[]` are described at https://github.com/silx-kit/h5z-htj2k#filter-cd_values.
