Installation

Direct Download / CDN

https://unpkg.com/cornerstone-tools (opens new window)

Unpkg.com (opens new window) provides NPM-based CDN links. The above link will always point to the latest release on NPM. You can also use a specific version/tag via URLs like https://unpkg.com/cornerstone-tools@2.0.0.

Include cornerstoneTools after Cornerstone and it will install itself automatically:

<script src="/path/to/cornerstone.js"></script>
<script src="/path/to/cornerstoneMath.js"></script>
<script src="/path/to/cornerstoneTools.js"></script>

NPM

npm install cornerstone-tools --save

When used with a module system, you can import cornerstoneTools like this:

// External Dependencies
import Hammer from "hammerjs";

// Cornerstone Libraries
import * as cornerstone from "cornerstone-core";
import * as cornerstoneMath from "cornerstone-math";
import * as cornerstoneTools from "cornerstone-tools";

// Specify external dependencies
cornerstoneTools.external.Hammer = Hammer;
cornerstoneTools.external.cornerstone = cornerstone;
cornerstoneTools.external.cornerstoneMath = cornerstoneMath;

You don't need to do this when using global script tags.

You will have to clone directly from GitHub and build cornerstoneTools yourself if you want to use the latest dev build.

git clone https://github.com/cornerstonejs/cornerstoneTools.git node_modules/cornerstoneTools
