 1 | # Changelog
 2 | All notable changes to this project will be documented in this file.
 3 | 
 4 | The format is based on [Keep a Changelog](http://keepachangelog.com/en/1.0.0/)
 5 | and this project adheres to [Semantic Versioning](http://semver.org/spec/v2.0.0.html).
 6 | 
 7 | ## [2.1.1] - 2018-12-05
 8 | ### Added
 9 | - Added default export named 'cornerstoneWebImageLoader' to the module
10 | 
11 | ## [2.1.0] - 2018-04-11
12 | ### Changed
13 | - Updated Webpack to version 4
14 | - DIST folder is now removed from the repository
15 | 
16 | ## [2.0.0] - 2017-12-08
17 | ### Changed
18 | 
19 | - *Breaking Change!!!* Switches image loader return values to support the breaking change in Cornerstone Master (https://github.com/cornerstonejs/cornerstone/commit/9448755397da10a6de6f694d83123274cbd4b38e) which requires image loaders to return an object of the form { promise, cancelFn }.
20 | - *Breaking Change!!!* Removed jQuery events from triggerEvent, lower-cased all the event names (i.e. 'cornerstoneimageloadprogress').
21 | - *Breaking Change!!!* Switched all Deferred usage to use Promises
22 | - Performance: Switch getPixelData to just return the canvas imageData.data. The previous loop to set alpha channel to 255 is unnecessary since we can now just set image.rgba = false.
23 | - Set image.rgba to false by default. Users can change this to have the image rendered with the alpha channel intact.
24 | - Switch event triggering to use cornerstone.triggerEvent
25 | - Switched this changelog to try to follow http://keepachangelog.com/en/1.0.0/
26 | 
27 | ## [1.0.0]
28 | 
29 | - Updated to 1.0.0 because 0.8.5 introduced a breaking change with Cornerstone / jQuery injection. This doesn't break usage if you are using HTML script tags, but if you are using a module system, Cornerstone Web Image Loader may not properly find its dependencies.
30 | 
31 | The solution for this is to inject your Cornerstone instance into Cornerstone Tools as follows:
32 | 
33 | ````javascript
34 | cornerstoneWebImageLoader.external.$ = $;
35 | cornerstoneWebImageLoader.external.cornerstone = cornerstone;
36 | ````
37 | 
38 | An example commit doing something similar in the OHIF Viewer Meteor application is here: https://github.com/OHIF/Viewers/commit/012bba44806d0fb9bb60af329c4875e7f6b751e0#diff-d9ccd906dfc48b4589d720766fe14715R25
39 | 
40 | We apologize for any headaches that the breaking change in 0.8.5 may have caused for those using module systems.
41 | - Note: the dependencies have been updated to require Cornerstone Core 1.0.0 or above
42 | 
43 | ## [0.8.6] (deprecated due to breaking change)
44 | 
45 | - Added native CustomEvents that are triggered parallel to the jQuery events. This is part of a transition to drop the jQuery dependency entirely.
46 | - *Note:* This version requires Cornerstone Core 0.13.2 or above, where cornerstone.events has the EventTarget interface!
47 | 
48 | e.g. CornerstoneImageLoadProgress has a native CustomEvent name 'cornerstoneimageloadprogress'
49 | 
50 | ## [0.8.5] (deprecated due to breaking change)
51 | 
52 | - Add Jquery and Cornerstone as injection dependencies

 1 | cornerstone Web Image Loader
 2 | =============================
 3 | 
 4 | A cornerstone (legacy) Image Loader for web images (PNG, JPEG) for cornerstone legacy. For cornerstone3D use the new loader [here](https://github.com/cornerstonejs/cornerstone3D-beta/blob/main/packages/core/examples/webLoader/registerWebImageLoader.ts) 
 5 | 
 6 | Live Examples
 7 | ---------------
 8 | 
 9 | [Click here for a live example of this library in use!](http://rawgit.com/cornerstonejs/cornerstoneWebImageLoader/master/examples/index.html)
10 | 
11 | View the [simple image viewer](http://viewer.ohif.org/) built on cornerstone.
12 | 
13 | Install
14 | -------
15 | 
16 | Get a packaged source file:
17 | 
18 | * [cornerstoneWebImageLoader.js](https://unpkg.com/browse/cornerstone-web-image-loader/dist/)
19 | * [cornerstoneWebImageLoader.min.js](https://unpkg.com/browse/cornerstone-web-image-loader/dist/)
20 | 
21 | 
22 | Or install via [NPM](https://www.npmjs.com/package/cornerstone-web-image-loader):
23 | 
24 | > npm install cornerstone-web-image-loader
25 | 
26 | Usage
27 | -------
28 | 
29 | 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:
30 | 
31 | ````javascript
32 | cornerstoneWebImageLoader.external.cornerstone = cornerstone;
33 | ````
34 | 
35 | 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().
36 | 
37 | Key Features
38 | ------------
39 | 
40 | * Provides a bridge between the cornerstone library and standard web images
41 | * Allows XHR to be hooked so custom http headers can be added (e.g. for authentication).  View the source of the
42 |   [example](http://rawgit.com/cornerstonejs/cornerstoneWebImageLoader/master/examples/index.html) to see how this is done.
43 | 
44 | Contributors
45 | ------------
46 | @onluiz for fixing a bug with images not being properly invalidated
47 | @leonardorame for adding support for CornerstoneImageLoadProgress
48 | 
49 | Build System
50 | ============
51 | 
52 | This project uses webpack to build the software.
53 | 
54 | Pre-requisites:
55 | ---------------
56 | 
57 | NodeJs - [click to visit web site for installation instructions](http://nodejs.org).
58 | 
59 | Common Tasks
60 | ------------
61 | 
62 | Update dependencies (after each pull):
63 | > npm install
64 | 
65 | Running the build:
66 | > npm start
67 | 
68 | Automatically running the build and unit tests after each source change:
69 | > npm run watch
70 | 
71 | Why is this a separate library from cornerstone?
72 | ================================================
73 | 
74 | Cornerstone was designed to support loading of any kind of image regardless of its container,
75 | compression algorithm, encoding or transport.  This is one of many possible image loaders
76 | that can provide the image pixel data to cornerstone to display
