Image Palette Posterizer

Image Palette Posterizer is a desktop color quantization, bit-depth posterization,
and palette extraction studio built for illustrators, UI designers, pixel artists,
and web developers on Linux.

Key Features:
- Quantizer & Posterize Lab: Reduce full-color artwork to 2-256 palette colors
using Median-Cut, MaxCoverage, or FastOctree reducers, or apply uniform and
custom per-channel R/G/B bit-depth posterization with optional Floyd-Steinberg
dithering and an interactive split comparison viewer.
- Dominant Swatch Extractor: Extract dominant K-color swatches with exact pixel
coverage percentages, relative luminance, and WCAG contrast ratio badges
(AA/AAA normal & large text pair checker), plus clean exports to GIMP Palette
(.gpl), CSS custom properties, JSON, and binary .aco swatch files.
- Batch Posterizer: Process entire photo folders into quantized or posterized
PNG, WebP, and JPEG outputs alongside a detailed palette CSV summary report.
