### Polyfill for IE and Edge
If you wish to use the file output, you'll need to polyfill the `toBlob` method of the HTML Canvas for IE and Edge.
```
if (!HTMLCanvasElement.prototype.toBlob) {
Object.defineProperty(HTMLCanvasElement.prototype, 'toBlob', {
value: function (callback, type, quality) {
var dataURL = this.toDataURL(type, quality).split(',')[1];
setTimeout(function() {
var binStr = atob( dataURL ),
len = binStr.length,
arr = new Uint8Array(len);
for (var i = 0; i < len; i++ ) {
arr[i] = binStr.charCodeAt(i);
}
callback( new Blob( [arr], {type: type || 'image/png'} ) );
});
}
});
}
