quantize

Node.js module for color quantization, based on Leptonica.

Install

npm install @colorthief/quantize

Quick Overview

Usage

var quantize = require('@colorthief/quantize');

var arrayOfPixels = [[190,197,190], [202,204,200], [207,214,210], [211,214,211], [205,207,207]];
var maximumColorCount = 4;

var colorMap = quantize(arrayOfPixels, maximumColorCount);

• arrayOfPixels - An array of pixels (represented as [R,G,B arrays]) to quantize
• maxiumColorCount - The maximum number of colours allowed in the reduced palette

Reduced Palette

The .palette() method returns an array that contains the reduced color palette.

// Returns the reduced palette
colorMap.palette(); 
// [[204, 204, 204], [208,212,212], [188,196,188], [212,204,196]]

Reduced pixel

The .map(pixel) method maps an individual pixel to the reduced color palette.

// Returns the reduced pixel
colorMap.map(arrayOfPixels[0]);
// [188,196,188]
