Get palette for any image file, no node-canvas

Package Exports

  • image-palette

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (image-palette) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

image-palette Build Status unstable

Extract palette from pixels array, return pixels mapped to palette. Useful for organizing palette-based encoding, like GIF, or various limited colors renderers, like gl-scatter2d.

Inspired by get-rgba-palette.

Usage

$ npm install image-palette

var palette = require('image-palette')
var pixels = require('image-pixels')

var {ids, colors} = palette(await pixels('./image.png'))

API

var {ids, colors, amount} = palette(pixels, count=5)

Extract palette from the input pixels array with rgba pixels sequence, whether flat or nested.

  • colors is a list of extracted colors [[r, g, b, a], [r, g, b, a], ...].
  • ids is an array of input pixels mapped to extracted colors.
  • amount is an array with amounts corresponding to the extracted colors, from 0..1 range.
  • count is max number of colors to extract.
  • image-pixels − load pixels data from any image source.
  • image-save − save image/pixel data to a file, canvas or array.
  • image-equal − test if two images are equal, based on fuzzy comparison.
