Usage

define(['toDataURL'], function (toDataURL) {
    var element = document.getElementByTagName('img')[0];
    var src = 'https://avatars0.githubusercontent.com/u/7076521?v=2&s=84';

    /* you can get the dataUrl from an element (not a url) synchronously, */
    console.log(toDataURL(element));
    // > data:image/png;base64,iVBORw0KGgo...

    /* but that sync method may cause some issues, so you can also make it by an async way. */
    toDataURL(element, {
        callback: function (err, data) {
            if (!err) console.log(data);
            // > data:image/png;base64,iVBORw0KGgo...
        }
    });

    /* or get the dataUrl from a url asynchronously */
    toDataURL(src, {
        callback: function (err, data) {
            if (!err) console.log(data);
            // > data:image/png;base64,iVBORw0KGgo...
        }
    });

    /* and define the width and height */
    toDataURL(src, {
        width: 120,
        height: 120,
        callback: function (err, data) {
            if (!err) console.log(data);
            // > data:image/png;base64,iVBORw0KGgo...
        }
    });

    /* maybe you just want the base64 data */
    toDataURL(src, {
        purify: true,
        callback: function (err, data) {
            if (!err) console.log(data);
            // > iVBORw0KGgo...
        }
