cornerstone-test-image-loader
This repository contains a cornerstone image loader that produces test images client side. This is really useful for supporting development activities and examples as no server is required.
WARNING: This image loader base 64 encodes the pixel data so cornerstone can view images without requiring a server (for development and example use cases). A better option that base 64 encoding your pixel data is to serve up the DICOM P10 via HTTP server and load it using the cornerstoneWADOImageLoader

Image Loaders
example
Produces MRI Head images:
- example://1 - MRI head image #1 (coronal)
- example://2 - MRI head image #2 (coronal)
ctexample
Produces CT chest image:
- ctexample://1 - CT chest image
string
Generates a 256x256 image with the specified string printed into the image:
- string://1 - Generates a 256x256 image with the string "1" rendered inside of it
- string://hello world - Generates a 256x256 image with the string "hello world" rendered inside of it
ramp
Generates a 256x256 image with a grayscale ramp based on the specified parameters (comma separated):
parameter 0 = width (default 256)
parameter 1 = height (default 256)
parameter 2 = bitsStored (default 8)
parameter 3 = columnPixelSpacing (default 1.0)
parameter 5 = rowPixelSpacing (default 1.0)
parameter 6 = slope (default 1.0)
parameter 7 = intercept (default 0.0)
ramp://256,256,8 - Generates a 256x256x1 image with a grayscale ramp covering 0-255 values
ramp://256,256,10 - Generates a 256x256x2 image with a grayscale ramp covering 0-1023 values
ramp://256,256,16 - Generates a 256x256x2 image with a grayscale ramp covering 0-65535 values
ramp://512,512,16,0.5,0.5,1.0,-1024 - Generates a 512x512x2 image with a grayscale ramp covering 0-65535 values and pixel spacing 0.5/0.5, slope = 1.0, intercept -1024
Build System
This project uses grunt to build the software.
Pre-requisites:
NodeJs - click to visit web site for installation instructions.
grunt-cli
npm install -g grunt-cli
bower
npm install -g bower
Common Tasks
Update dependencies (after each pull):
npm install
bower install
Running the build:
grunt
Automatically running the build and unit tests after each source change:
grunt watch
The build will generate the library output in /dist and the output for the live examples in ../cornerstone-test-image-loader-build. The example output is committed to the gh-pages branch so it can be viewed properly in github pages
