## プロジェクトの歴史と使われ方

imgdiff is a small Go command-line utility for pixel-by-pixel image comparison. Its public README frames the project as a faster response to odiff, another visual-diff tool used in image-regression and screenshot-testing workflows.

### プロジェクトの歴史

The GitHub repository was created on 2020-12-12, and the v1.0.0 release was published the same day as an initial release with pre-built binaries. Follow-up releases in February and March 2021 fixed package-path and output-writing issues, after which the package remained a compact single-purpose visual comparison tool.

### 採用の歴史

Adoption appears niche but visible: the repository has roughly 1.7k GitHub stars in repository metadata, and Homebrew publishes a formula for macOS users. Homebrew analytics for the formula show low install counts, which fits a developer-tooling utility used mainly inside visual test and image-comparison workflows.

### 使われ方

The README documents a CLI that accepts base, compare, and output image paths, with options for color-difference threshold, diff-image rendering, and layout-failure behavior. The intended use is direct image comparison rather than general image editing.

### パッケージ好きにとっての重要性

imgdiff is package-nerd interesting because it is a tiny Go binary competing on startup simplicity and benchmark performance against heavier image-processing stacks. It represents the class of single-binary tools that package managers can expose for CI and screenshot-regression jobs without pulling in a larger application.

### タイムライン

- 2020-12-12: GitHub repository created and v1.0.0 initial release published.
- 2021-02-17: v1.0.1 fixed the package path.
- 2021-03-25: v1.0.2 fixed output writing.
- 2026: Homebrew formula metadata lists imgdiff as a pixel-by-pixel image difference tool.

### Related projects

- The README explicitly compares imgdiff with odiff. It also fits the broader visual-regression ecosystem around screenshot testing and pixel-diff utilities.
