history

Project history and usage

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.

Project history

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.

Adoption history

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.

How it is used

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.

Why package nerds care

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.

Timeline

  • 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.
