JPEG 2000 and HTJ2K public codec crate for J2K.
This crate exposes inspect, decode, encode, recode, device-surface, and
encode-stage adapter contracts backed by the native J2K engine and optional
device adapters.
The encode-stage adapter module is a backend SPI for CUDA, Metal, and transcode
integration. It is not the primary end-user encode API.
For JPEG 2000 / HTJ2K application code, use this crate directly.
