The official SourceForge project page and wiki describe it as aimed at parallel and robust image processing. ### プロジェクトの歴史 The SourceForge project was registered on October 2, 2006. Its public project metadata lists a last update of June 17, 2014, suggesting a mature but quiet utility rather than an actively evolving media stack. ### 採用の歴史 EPSILON's visible adoption is narrow: it is packaged by Homebrew in this dataset and hosted on SourceForge with code, wiki, tickets, mailing lists, and file releases. The official page lists BSD, Linux, and Windows as operating systems. ### 使われ方 The package provides an epsilon command plus helper scripts for starting and stopping EPSILON nodes, fitting its stated focus on parallel image-processing workflows. ### パッケージ好きにとっての重要性 EPSILON is interesting mostly as a niche compressor: wavelet-based, command-line friendly, and old enough to preserve a SourceForge-era image-processing project in modern package managers. ### タイムライン - 2006: SourceForge project registered. - 2014: SourceForge project page lists its last update. ### Related projects - The project is adjacent to other command-line image-compression and image-processing tools, but no direct upstream companion project is documented in the official sources. ### ソース - - - ## セキュリティノート broad file, network, media, or database tool signal. - **Geiger リスク:** blue / 中 - broad file, network, media, or database tool signal ## ソースデータベース詳細 - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** epsilon - **Version Scheme:** 0 - **Revision:** 0 - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## 関連リンク - [Secret-risk packages](https://pkg.so/ja/secret-risk-packages/) - Has protected-tool coverage, approval-gate, or non-low Geiger security signals. - [Terminal utility packages](https://pkg.so/ja/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Archive and compression packages](https://pkg.so/ja/archive-compression-tools/) - Matched archive or compression metadata. - [Networking and protocol packages](https://pkg.so/ja/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [libtool](https://pkg.so/ja/brew/libtool/) - Build dependency declared by Homebrew. - [autoconf](https://pkg.so/ja/brew/autoconf/) - Build dependency declared by Homebrew. - [automake](https://pkg.so/ja/brew/automake/) - Build dependency declared by Homebrew. - [gdal](https://pkg.so/ja/brew/gdal/) - Popular package that depends on this formula. - [giflib](https://pkg.so/ja/brew/giflib/) - Shares pkgdb curated category or tags: cli, image-processing, media. - [leptonica](https://pkg.so/ja/brew/leptonica/) - Shares pkgdb curated category or tags: cli, image-processing, media. - [netpbm](https://pkg.so/ja/brew/netpbm/) - Shares pkgdb curated category or tags: cli, image-processing, media. - [gifsicle](https://pkg.so/ja/brew/gifsicle/) - Shares pkgdb curated category or tags: cli, image-processing, media. - [openimageio](https://pkg.so/ja/brew/openimageio/) - Shares pkgdb curated category or tags: cli, image-processing, media. - [nip4](https://pkg.so/ja/brew/nip4/) - Shares pkgdb curated category or tags: cli, image-processing, media. - [apngasm](https://pkg.so/ja/brew/apngasm/) - Shares pkgdb curated category or tags: cli, image-processing, media. - [libsail](https://pkg.so/ja/brew/libsail/) - Shares pkgdb curated category or tags: cli, image-processing, media. - [ebook-tools](https://pkg.so/ja/brew/ebook-tools/) - Both packages touch the same language runtime or ecosystem.
