Install

Get a packaged source file:

cornerstoneWebImageLoader.js cornerstoneWebImageLoader.min.js

Or install via NPM:

npm install cornerstone-web-image-loader

Usage

Simply include the cornerstoneWebImageLoader.js in your HTML file after you load cornerstone.js and then set the cornerstone instance as an external module for cornerstoneWebImageLoader:

cornerstoneWebImageLoader.external.cornerstone = cornerstone;

This will let cornerstoneWebImageLoader register itself with cornerstone to load imageId's that have the http or https url schemes. To display an image, pass the url to the image as the imageId parameter to a cornerstone API function loadImage().

Key Features Provides a bridge between the cornerstone library and standard web images Allows XHR to be hooked so custom http headers can be added (e.g. for authentication). View the source of the example to see how this is done. Contributors
