Description

This demo shows the usage of the AlphaJpg-Canvas.js library. A specially crafted jpg image is loaded from an external domain. It's alpha transparency is reconstructed using HTML5 canvas. The returned canvas element is attached to the DOM. The canvas is wrapped in two div elements and styled so that it behaves like a responsive image.

Support

This technique requires Javascript, canvas, and an external server that is capable of delivering CORS enabled images. Internet Explorer 9 does not support CORS enabled images.
