This is a fork of Jordan Gensler's Vanilla Pinch NPM Package

VanillaPinchZoom

VanillaPinchZoom is a fork of PinchZoom.js with no jQuery dependency. The library provides multi touch gestures for zooming and dragging on any DOM element.

Finally, you are free of the shackles of jQuery! All you need is a modern browser.

Usage

The library exports a CommonJS module, and is designed for use with Browserify. For your conveience, a built version of VanillaPinchZoom is included in dist/, which is a standalone Browserify bundle that assigns VanillaPinchZoom on the global object.

var VanillaPinchZoom = require('vanillapinchzoom');

var myVanillaPinchZoom = new VanillaPinchZoom(document.querySelector('#your-element'), options);

Options

tapZoomFactor:          The zoom factor a double tap zooms to. (default 2)
