概览
Enable lossless editing of PNGs via a textual representation
历史
SNG, Scriptable Network Graphics, is a textual representation for PNG files plus a compiler/decompiler named sng. It enables lossless editing of PNG structure and ancillary chunks using text tools.
The official NEWS file records a private pre-alpha release in December 1999, a public alpha days later, and a 1.0.0 production release in July 2001. The project is maintained by Eric S. Raymond and hosted on SourceForge with an official Git code browser.
SNG has stayed small but packageable: the official README says the code is commonly packaged as sng, and the supplied package facts list Homebrew, Debian/Ubuntu, Fedora, and Nix packages.
The sng program translates PNG to SNG and SNG back to PNG. Official documentation emphasizes viewing and editing obscure ancillary chunks and generating PNG content from scripts.
SNG is classic Unix packaging material: a small C command-line tool, a man page, a regression test, libpng dependency, and a stable file-format niche that has survived many libpng transitions.
