Is it possible to apply a mask on an image using jquery/javascript/html5?

I am looking for a way to cat a part of an image, using another image as a mask.

I don't know if this is at all possible using web technologies. I am willing of using libraries (jquery, php, javascript) or anything available on the market that d开发者_高级运维oes just that.

In general, I want to create themes that use resources that I don't have to cut in order to make them in different shapes (rectangles, circles etc). I onlywant to be able to apply a mask to them on the fly.

I am aware of ImageMagick® but cant figure out a way on how to use it to have such results without making my code ugly.

If you don't have a clue on what masking is, here's a link.

If I understand well you're talking about juxtaposing images. If so, you can encapsulate a div into another, like this:

<div id="div1">
 <div id="<div2">
 </div>
</div>

And then put your image as a CSS background for div2 and the mask for div1.
