## プロジェクトの歴史と使われ方

apngasm is an APNG assembler CLI and library for creating, and in the newer GitHub version also disassembling, Animated PNG files. It is one of the core APNG-family utilities alongside disassemblers and GIF/APNG converters.

### プロジェクトの歴史

The older SourceForge-hosted APNG Assembler page describes a command-line and GUI tool that creates APNG animations from PNG or TGA image sequences. It emphasizes inter-frame optimization, palette and color-type optimization, and zlib, 7zip, and Zopfli compression options.

The current GitHub project was created in July 2013 and calls itself the next generation of apngasm. Its README documents a CMake-based cross-platform build, CLI and library packaging, Java and Ruby wrappers generated through SWIG, and copyright shared as a joint production by Max Stepin and K.K. GenSouSha.

Official GitHub releases show the 3.1.x line in 2014 and 2015, followed by a 3.1.10 release in 2021 for newer build and packaging systems plus small fixes.

### 採用の歴史

The README recommends Homebrew for the latest macOS apngasm, GitHub releases for Windows, and a Launchpad PPA for GNU/Linux. The supplied package metadata also records Homebrew, Debian, Nix, Scoop, and Ubuntu packages, indicating broad packaging for a specialized image tool.

The SourceForge feed shows prebuilt 2.91 artifacts for Linux, macOS, and Windows in 2016, while the GitHub repository shows the later source-control home for the next-generation codebase.

### 使われ方

The SourceForge documentation shows commands such as apngasm output.png frame001.png [options] and apngasm output.png frame*.png [options]. Options include frame delay, loop count, skipping the first frame, keeping palette or color type, compression backend, and iteration counts.

The GitHub README is more build- and packaging-oriented, with platform-specific dependency lists and package-building instructions rather than a fixed user config file.

### パッケージ好きにとっての重要性

apngasm matters because APNG is a format niche where small command-line utilities define the practical toolchain. It gives packagers a native assembler that can be scripted, built through CMake, wrapped as a library, and distributed through distro repositories.

Its evolution from SourceForge binaries and GUI/CLI zips to a GitHub-hosted CMake project is a compact example of how older image-format utilities migrated into modern package-manager ecosystems.

### タイムライン

- 2013: Current apngasm/apngasm GitHub repository was created.
- 2014: GitHub 3.1.x releases began, including libapngasm updates.
- 2016: SourceForge feed records APNG Assembler 2.91 source and platform binary releases.
- 2021: GitHub 3.1.10 release updated builds and packaging for newer systems.

### Related projects

- The official SourceForge page links apngdis, gif2apng, apng2gif, and apngopt as related APNG utilities. The GitHub README also points Ruby users toward the rapngasm gem.
