react-image-filter v0.1.2

React Image Filter

Lightweight React component, for applying color filters on images, works in all modern browsers plus IE10+ and Edge. Made because CSS filters don't work in IE and Edge :(

Component is written as ES module, so it will work with webpack and other module bundlers (which is standard for React apps anyway). Tested with react-create-app and my boilerplate, Marvin.

Demo

Check the interactive demo.

Quick start

Get it from npm

$ npm install --save react-image-filter

Import and use it in your React app.

import React, { Component } from 'react';
import ImageFilter from 'react-image-filter';

class Example extends Component {
  render() {
    return (
      <ImageFilter
        image='https://source.unsplash.com/random/1200x800'
        filter={ 'duotone' } // see docs beneath
        colorOne={ [40, 250, 250] }
        colorTwo={ [250, 150, 30] }
      />
    );
  }
}
