## プロジェクトの歴史と使われ方

OpenJPH is a BSD-licensed open-source implementation of High-Throughput JPEG 2000, also known as HTJ2K, JPH, JPEG 2000 Part 15, ISO/IEC 15444-15, and ITU-T T.814. It focuses on the Part 15 codec rather than being a general replacement for every JPEG 2000 feature.

### プロジェクトの歴史

OpenJPH was developed by Aous Thabit Naman to implement an HTJ2K encoder and decoder. The project name follows the .jph file extension assigned to the HTJ2K file format.

The upstream README is explicit about scope: OpenJPH implements HTJ2K while supporting selected JPEG 2000 Part 1 features, such as the reversible 5/3 and irreversible 9/7 wavelet transforms. That narrow scope is part of the package's identity; it is an implementation of the high-throughput path, not a grab bag of every JPEG 2000 variant.

### 採用の歴史

HTJ2K was standardized to replace the original JPEG 2000 block coder with a faster HT block coder while preserving much of the JPEG 2000 architecture. The Library of Congress format description notes an order-of-magnitude throughput increase and describes use cases such as professional video capture, mobile and satellite imaging, preview, browsing, and archiving or delivery workflows.

OpenJPH appears in the early open-source implementation set for HTJ2K. The Code4Lib Journal's IIIF evaluation describes cultural-heritage interest in HTJ2K as a drop-in replacement path for JPEG 2000 deployments, with open-source tools such as OpenJPEG and Grok also part of that testing landscape.

### 使われ方

Developers use OpenJPH when they need to encode, decode, test, or embed HTJ2K/JPH support without buying a proprietary SDK. The package is especially relevant for experiments and production prototypes around faster JPEG 2000 delivery, partial-resolution decoding, WebAssembly/Javascript demos, and image-server pipelines.

For Homebrew users, openjph supplies the codec implementation as a packaged C/C++ project rather than a white-paper reference. That is useful for downstream projects that want to compile against a system library and for operators comparing HTJ2K tooling on ordinary developer machines.

### パッケージ好きにとっての重要性

OpenJPH is small but strategically interesting: it packages a newer image standard where the standards documents, reference software, and practical deployment ecosystem are still close together. That makes package metadata, source URLs, and version tracking more important than popularity signals alone.

It also complements OpenJPEG rather than simply replacing it. OpenJPEG represents the older JPEG 2000 baseline; OpenJPH is focused on the high-throughput Part 15 branch and the .jph ecosystem.

### タイムライン

- 2017-2019: JPEG committee work on HTJ2K progressed from call-for-proposals activity to ISO publication of JPEG 2000 Part 15.
- June/August 2019: ITU-T T.814 and the shared ISO/IEC 15444-15 text established the high-throughput JPEG 2000 standard.
- 2020s: OpenJPH developed as an open-source HTJ2K implementation with encoder, decoder, documentation, demos, and packaged releases.

### Related projects

- OpenJPH is related to HTJ2K/JPH, JPEG 2000 Part 1, OpenJPEG, Grok, Kakadu, IIIF image servers, the Library of Congress format-sustainability work, and JPEG committee standards documents.
