## 项目历史与用法

gif2png is a classic image-conversion utility that converts GIF files to PNG and ships with `web2png`, a front end for converting web hierarchies and rewriting image references. It is strongly associated with the late-1990s move from GIF toward PNG on the open web.

### 项目历史

The project predates its GitLab hosting and has a long changelog preserved by Eric S. Raymond's project page. The NEWS file shows releases in 1999 leading up to version 2.0.0, which was marked ready for Burn All GIFs Day, a campaign-era milestone in PNG advocacy.

Development continued through portability, packaging, and correctness work: DocBook documentation in 2002, RPM and Freshmeat packaging updates in 2003, libpng and security fixes in the 2000s and 2010s, a simpler makefile after Autotools removal in 2015, a Go port in 2019, and Go module packaging in 2023.

### 采用历史

gif2png's adoption was rooted in a specific historical problem: GIF was ubiquitous but politically and technically contentious, while PNG offered a patent-free replacement for many web graphics. The utility gave web maintainers a batchable path to convert image assets and update references.

The package's continued presence in Homebrew, Fedora, Arch, and other packaging indexes reflects its role as a small, stable conversion tool rather than a large image suite. Users who need this exact conversion can install a purpose-built command instead of pulling in a broad graphics application.

### 使用方式

Practitioners use `gif2png` for file-level GIF to PNG conversion and `web2png` when converting a directory tree of web pages and image references. The README describes POSIX and Go build requirements, a regression test suite, and the `make check` workflow.

Typical use is archival cleanup, static-site maintenance, packaging tests around image conversion, or migration of old GIF-heavy web assets to PNG.

### 为什么软件包爱好者会关心

gif2png is package-nerd significant because it is old, focused, and still easy to package. Its changelog records decades of small portability and correctness fixes, including security hardening and a language-port transition from C-era tooling to Go while keeping the command-line identity intact.

### 时间线

- 1999: Version 2.0.0 was prepared for Burn All GIFs Day.
- 2002: Documentation masters moved to DocBook.
- 2003: RPM and Freshmeat packaging updates landed in the 2.5 series.

- 2015: Autotools was removed in favor of a simple makefile.
- 2019: The code was ported to Go.
- 2023: The build was converted to a Go module.
