resemble-image v1.0.2

resemble-image

Provide color stops for a gradient that loosely resembles the original image.

This package contains the algorithms getEqualWidthStops and getVariableWidthStops as described in Thoughts on Linear Gradients That Resemble Images.

npm install resemble-image --save-dev

import { getEqualWidthStops, getVariableWidthStops } from 'resemble-image';

var getEqualWidthStops = require('resemble-image').getEqualWidthStops;
var getVariableWidthStops = require('resemble-image').getVariableWidthStops;

Each function returns a promise, which resolves in an array of color–position pairs.

getEqualWidthStops(image, { fidelity: 4 }).then((stops) => console.log(stops));
// [ { color: '#023d33', position: 0 },
//   { color: '#036357', position: 25 },
//   { color: '#91aaa5', position: 50 },
//   { color: '#cdcfd5', position: 75 } ]

getVariableWidthStops(image, { fidelity: 4 }).then((stops) => console.log(stops));
// [ { color: '#043630', position: 9.77 },
//   { color: '#02554b', position: 33.79 },
//   { color: '#c4c6dd', position: 67.97 },
//   { color: '#c4c6dd', position: 95.31 } ]
