libimagequant

brew install libimagequant v4.4.1 GPL-3.0-or-later AND HPND

C library for high-quality color palette quantization and image posterization.

Why you might care

Extracts optimal color palettes from images to reduce file size or convert RGB to indexed color, used internally by pngquant. Valuable as a shared library dependency for image processing tools that need deterministic, perceptually-optimized palette selection without external image conversion calls.
