cornerstoneTools
================

`cornerstoneTools` is a library built on top of [cornerstone](https://github.com/cornerstonejs/cornerstone) that provides
a set of common tools needed in medical imaging to work with images and stacks of images.

Getting Started
---------------

### Install

**Via NPM:** (preferred)

_Latest stable release:_
- `npm install --save cornerstone-tools`

_Pre-release, unstable, mostly for contributors:_
- `npm install --save cornerstone-tools@next`

**Get a packaged source file:**

[UNPKG](https://unpkg.com/#/) offers a quick/neat solution for grabbing versioned copies of the source. For example:

`https://unpkg.com/<package-name>@<package-version>/path/to/desired-file.js`


* For development, to get the latest minified source:
    * `<script src="https://unpkg.com/cornerstone-tools"></script>`
* For production, specify a package version:
    * `<script src="https://unpkg.com/cornerstone-tools@0.9.0"></script>`


### Usage

See the [live examples](https://rawgithub.com/cornerstonejs/cornerstoneTools/master/examples/index.html) and [wiki](https://github.com/cornerstonejs/cornerstoneTools/wiki) for documentation (Soon to be replaced by [tools.cornerstonejs.org](http://tools.cornerstonejs.org/)) on how to use this library


**A common setup when using modules:**

````javascript
// Load NPM packages
import Hammer from 'hammerjs';                    // npm install --save hammerjs
import * as cornerstone from 'cornerstone-core';  // npm install --save cornerstone-core
import * as cornerstoneTools from 'cornerstone-tools';

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

*Note: `cornerstoneTools.external`'s only need to be specified in `cornerstone-tools` versions 1.0.0+


**A common setup when using package source files:**

````javascript
// Load Packaged Sources
<script src="https://unpkg.com/hammerjs@2.0.8/hammer.js"></script>
<script src="https://unpkg.com/cornerstone-core@2.0.0/dist/cornerstone.min.js"></script>
<script src="https://unpkg.com/cornerstone-tools@2.0.0/dist/cornerstoneTools.min.js"></script>

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

*Note: `cornerstoneTools.external`'s only need to be specified in `cornerstone-tools` versions 1.0.0+

A quick "here is how I intend to approach this problem", with sign-off from someone like @swederik, will go a long way toward increasing the chances your hard work will be merged :+1:

**How To Contribute:**

1. Fork this repository
2. Clone the forked repository
3. Before committing code, create a branch-per-feature, or branch-per-bug
4. Create pull requests against `cornerstonejs/cornerstoneTools/master`

**What To Contribute:**

If you're looking to get your feet wet, start by:

- Read existing [wiki documentation](https://github.com/cornerstonejs/cornerstoneTools/wiki) as you implement your solution. Notice any holes? Fill them in.
  - Soon to be replaced by [tools.cornerstonejs.org](http://tools.cornerstonejs.org/)
- Can't find an [example of a tool](https://rawgit.com/cornerstonejs/cornerstoneTools/master/examples/index.html)? Or think an example can be improved? Improve it.
- Creating your first tool and learned some lessons along the way? Add documentation to help others.

Can't think of anything? Weigh in on and claim an [outstanding issue in the backlog](https://github.com/cornerstonejs/cornerstoneTools/issues).


Versioning
----------

cornerstoneTools will be maintained under the [Semantic Versioning Guidelines](http://semver.org) as much as possible. Releases will be numbered with the following format:

`<major>.<minor>.<patch>`

And constructed with the following guidelines:

* Breaking backward compatibility bumps the major (and resets the minor and patch)
  - Information on how to navigate breaking changes will be included in our [Change Log](https://github.com/cornerstonejs/cornerstoneTools/blob/master/changelog.md)
* New additions, including new icons, without breaking backward compatibility bumps the minor (and resets the patch)
* Bug fixes, changes to brand logos, and misc changes bumps the patch


Build System
------------

This project uses webpack to build the software.

**Requirements:**

* [NodeJs](http://nodejs.org).

**Common Tasks:**


Update dependencies (after each pull):
> npm install

Running the build:
> npm start

Automatically running the build and unit tests after each source change:
> npm run watch

Backlog
------------

* Updating related handles while resizing (e.g. resize top left handle of a rect and update the bottom left and top right as it changes)
* measurement calibration tool
* Config object that allows tool appearance to be customized (e.g. line color, text color, handle size, shape, etc)
* automatically disabling tools when the enabled element is disabled
* reconsider the state management api, it is a bit clunky
* add support for pointer events as an input source
* Reference line renderer for first/last/active
* key press input source - so user can interact with tools via keyboard (e.g. scroll stack image using arrow keys)
