软件包摘要
Tool for optimizing PNG images
历史
项目历史与用法
pngnq is a command-line utility for converting RGBA PNG images to indexed palettes with two to 256 colors using a NeuQuant-derived neural-network algorithm.
项目历史
Stuart Coyle created pngnq as an adaptation of Greg Roelofs's pngquant code using Anthony Dekker's NeuQuant algorithm, extended for four-channel RGBA data. The first release was 0.3 in June 2004; development resumed in 2006, the project moved to SourceForge in 2007, and improvements by Kornel Lesiński were merged for version 1.0 in 2009.
采用历史
The project supplied binaries for Linux, macOS, BSD, and Windows and later entered several Unix-like package collections. Its official site records a move to SourceForge in 2007.
使用方式
Run pngnq on PNG files to produce reduced-palette output; the official example combines `pngnq -n 256` with pngcrush. The utility deliberately focuses on quantization rather than serving as an all-in-one compression pipeline.
为什么软件包爱好者会关心
pngnq represents the neural-network branch of classic PNG palette-reduction tools. It is interesting as a specialized alternative to pngquant's historically median-cut-derived approach and as a composable predecessor to later image-optimization pipelines.
