quantize ======== Node.js module for color quantization, based on Leptonica. Install ------- npm install quantize Quick Overview -------------- ###Usage `````javascript var quantize = require('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. `````javascript // 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. `````javascript // Returns the reduced pixel colorMap.map(arrayOfPixels[0]); // [188,196,188] ````` Author ------ * [Olivier Lesnicki](https://github.com/olivierlesnicki) Contributors ------------ * [Nick Rabinowitz](https://github.com/nrabinowitz) * [Mike Bostock] (https://github.com/mbostock) License ------- Licensed under the MIT License.
