viewfinder v1.0.9

viewfinder

Allow users to select an image and crop it inline, removing user confusion when the image is later served and freeing up those precious cycles on the backend

Demo

Usage

npm install --save viewfinder

import Viewfinder from 'viewfinder';

if (process.env.BROWSER) {
    require('viewfinder/dist/viewfinder.css');
}

class App extends React.Component {
    save() {
        const a = document.createElement("a");
        a.style.display = 'none';
        document.body.appendChild(a);

        // out takes an optional parameter that scales output image relative
        // to the DOM image
        a.href = this.image.out(4);
        a.download = 'viewfinder-image.png';
        a.click();
    }

    render() {
        return (
            <Viewfinder
                ref={ (c) => this.image = c.image }
                scale={ 0.5 } />
            <Button onClick={ this.save.bind(this) }>
                Save
            </Button>
        );
    }
}
