An HTML5 Slideshow w/ Canvas & jQuery

You’ve probably heard a lot about the new HTML5 canvas element. As the name implies, this is a special element that allows us to create and modify graphics. In addition, we can also use it like any other element on the page – apply jQuery animations on it, listen for events and integrate it deeply into our layouts.

All uses of canvas you’ve come so far are probably limited to games and other proof of concept demos. Today, however, we are doing something practical – we are making a progressively enhanced slideshow with a fancy transitioning effect, which is perfectly functional in older browsers as well.

With JavaScript, we are going to apply a special filter to every image in the slideshow. We will create a new version of the images, with higher contrast and more vivid colors, and store it in a canvas elements.
