A wonderful image library.

imago.js

It's a wonderful image library! With the purpose to facilitate the manipulation of images, imago.js enables you to perform trimming and resizing. Example page

install

Available on npm and bower: npm install imago-js, bower install imago.js or directly download

basic usage

// create a new imago instance
var imago = new Imago(document.getElementsByTagName('image')[0]);

// to start a edition
imago.edit();

// to save edited image
imago.save();

// to cancel current edition
imago.cancel();

imago.reset();

if the image element already has editing attributes and/or editing elements it will be rendered according to them.

<img src="example.jpg" data-original-width="640" data-original-height="424" data-width="640" data-height="424" data-top="0" data-left="0">
