## プロジェクトの歴史と使われ方

jpeginfo is Timo Kokkonen's small Unix-style utility for listing JPEG/JFIF metadata and checking file integrity. Its project page describes it as a tool for informative JPEG listings, error checks, and optional deletion of broken JPEG files.

### プロジェクトの歴史

The README records copyright years starting in 1995 and lists v1.0 as the first public release. The program was built on IJG libjpeg and kept the style of traditional command-line inspection tools: one binary, option flags, report columns, and exit codes suitable for shell scripts.

Later releases added checksum support, GNU autoconf configuration, comment and Exif recognition, CSV and JSON output, stdin support, and stronger digest options. GitHub releases in January and October 2023 document the modern 1.6 and 1.7 series.

### 採用の歴史

jpeginfo appears in Unix package collections as a companion to image-processing pipelines, especially where maintainers need a lightweight integrity checker rather than a full image editor. Its availability through Homebrew, Debian, Fedora, MacPorts, Nix, Ubuntu, and openSUSE reflects that quiet utility role.

### 使われ方

Typical use is batch inspection of JPEG dimensions, markers, progressive/non-progressive status, comments, and optional checksum columns. The `--check` mode makes it useful in scripts that reject damaged uploads or clean photo archives.

### パッケージ好きにとっての重要性

jpeginfo is package-nerd useful because it exposes low-level JPEG facts without dragging in a heavyweight graphics stack. It pairs naturally with `jpegoptim`: one tool checks and reports, the other rewrites and compresses.

### タイムライン

- 1995: Copyright period begins in the upstream README.
- v1.0: First public release, as listed in the upstream history.
- 2023-01-08: v1.6.2 added SHA-256 digest support and improved Win32 support.
- 2023-01-16: v1.7.0 added CSV output, JSON output, stdin support, headers, and SHA-512 support.
- 2023-10-29: v1.7.1 added `--files-from` and `--files-stdin`.

### Related projects

- Related projects include IJG libjpeg, libjpeg-turbo, mozjpeg, and jpegoptim.
