zoomable

Super simple pinch zooming for DOM elements on devices!

Zoomable enables you to pinch zoom DOM elements on devices by just adding some attributes to your elements.

usage

1. Drop zoomable.min.js into your scripts.
2. Add the attribute zoomable to your zoomable elements.
3. Add the attribute zoom-rate to your elements defining the rate at which element which scale upon pinch. For example; a zoom rate of 0.1 means that as you pinch, the element will go from 1.0 to 1.1 to 1.2 etc.
4. Optionally define a top and lower limit for element scale using lower-limit and upper-limit. For example; to stop your element from becoming smaller than half it's size set the lower-limit to 0.5. For example,

  <div zoomable zoom-rate="0.1"> My zoomable element </div>

uses

Zoomable mainly becomes useful for when you are trying to manipulate images within applications. For example, when you are cropping an image for say a profile picture.
