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. ### Sources - - - - - - source_facts.package-manager ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Other Package-Manager Records - Debian apt - apngasm - 2.91-5+b1: normalized package name match | Debian stable package indexes: apngasm from https://deb.debian.org/debian/dists/stable/main/binary-amd64/Packages.xz | assemble APNG animation from PNG/TGA image sequence | https://sourceforge.net/projects/apngasm/ - Nix - apngasm: normalized package name match | nixpkgs package indexes: pkgs/by-name/ap/apngasm/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 - Ubuntu apt - apngasm - 2.91-5build2: normalized package name match | Ubuntu 24.04 LTS package indexes: apngasm from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | assemble APNG animation from PNG/TGA image sequence | https://sourceforge.net/projects/apngasm/ - Scoop - main/apngasm: normalized package name match | Scoop official bucket manifest trees: bucket/apngasm.json from https://api.github.com/repos/ScoopInstaller/Main/git/trees/master?recursive=1 ## Combined YAML source View the package source record on GitHub.
