zoom.js

Enables a minimal JS API for zooming in on specific points or DOM elements.

Note that this is only a proof of concept so don't use it for anything important. Does not work in IE, yet.

Try out the demo.

Usage

Zoom in on an element:

  zoom.to({
    element: document.querySelector( 'img' )
  });

Additional options:

  zoom.to({
    element: document.querySelector( 'img' ),

    // Amount of empty space around zoomed element
    padding: 20,

    // Function to call once zooming completes
    callback: function() { /* ... */ }
  });

Zoom in on a point:

  zoom.to({
    x: 100,
    y: 200,
    width: 300,
    height: 300
  });

  zoom.to({
    x: 100,
    y: 200,
    scale: 3
  });

Reset

  zoom.out();
