• Download SVG Morpheus from GitHub.
• Use Bower to download the library. Just run bower install svg-morpheus in the directory you want to download the files to.

Add Script

Simply add the svg-morpheus.js script to your website/application. No other scripts are needed. Both the minified and uncompressed (for development) versions are in the /compile folder.

<script src="svg-morpheus.js"></script>

Usage

1. Add an icon set SVG to the HTML file where you want to show the morphing icon.
2. Create a SVG Morpheus instance for the icon set by calling new SVGMorpheus(element). Object/IFrame/Inline SVG element containing the icon set. Can be a DOM element or a CSS query selector.. For example:

var myIcons = new SVGMorpheus('#myIconSet');

3. After initializing, you get a SVGMorpheus object having to(ID) function. ID is an id of Icon in the icon set. Use it to morph the icon to another icon in the icon set.

myIcons.to('icon1');

Icon Set structure

SVG should have the following structure to be a valid icon set:

• 1st tier nodes are <g> elements having 'id' attribute. They define icons in the icon set.
• 2nd tier nodes are shape elements (<path>, circle, rect, ellipse, polygon, line). They define the icon graphics.

<svg>
  <g id="icon1">
    Shape elements
  </g>
  <g id="icon2">
    Shape elements
  </g>
</svg>
