The problem
Building one or two tools on top of Cornerstone.js is not that difficult. However, as the number of tools grow, you begin to encounter difficult problems:
- Tools should behave and be configurable in a consistant way
- Managing tools across multiple cornerstone
enabled elements
- Tools that need knowledge of a fellow tool’s state
- The ability to “drop-in” others’ tools, and they “just work”
- and many others
This library solves these problems in a highly pluggable and extensible way.
This solution
cornerstone-tools is a light-weight solution for building Tools on top of Cornerstone.js. It’s only dependencies are libraries within the Cornerstone family. Instead of trying to “do everything” it aims to be extensible and pluggable to aid in the rapid development of new tools. Ideally, tools created using cornerstone-tools can be easily shared, allowing for the creation of a broader ecosystem.
Example
Below is a simplified example of creating a tool by extending cornerstone-tool’s BaseTool class.
import cornerstone from 'cornerstone-core';
import { BaseTool } from 'cornerstone-tools';
import basicLevelingStrategy from '...';
export default class WwwcTool extends BaseTool {
constructor(configuration = {}) {
const defaultConfig = {
name: 'Wwwc',
strategies: { basicLevelingStrategy },
supportedInteractionTypes: ['Mouse', 'Touch'],
configuration: {
orientation: 0,
},
};
const initialConfiguration = Object.assign(defaultConfig, configuration);
super(initialConfiguration);
}
mouseDragCallback(evt) {
this.applyActiveStrategy(evt);
cornerstone.setViewport(evt.detail.element, evt.detail.viewport);
}
touchDragCallback(evt) {
evt.stopImmediatePropagation();
this.applyActiveStrategy(evt);
cornerstone.setViewport(evt.detail.element, evt.detail.viewport);
}
}
Installation
This module is distributed via npm which is bundled with node and
should be installed as one of your project’s dependencies:
npm install --save cornerstone-tools
npm install --save cornerstone-tools@2
This library has peerDependencies listings for:
hammerjs - Better touch supportcornerstone-corecornerstone-math - Simplifies and provides shared complex tool math logic- Any Cornerstone “Image Loader”
cornerstone-web-image-loader - JPEG/PNG imagescornerstone-wado-image-loader - DICOM images; also parses tags for tool use
If you need to support the IE11 Browser, you will need to provide polyfills as needed. Our BrowserList target:
"browserslist": [
"> 1%",
"IE 11",
"not dead",
"not IE < 11",
"not op_mini all"
]
Setting up and configuring cornerstone-tools’s depency can be the biggest hurdle to getting started. Be sure to check out our docs for assistance.
