Sample image generator to dynamically create images suitable for Aotal assessment apps (as described at http://talentappstore.github.io/tas-tenant-apis/doc/assessment-apps.html), using node-canvas.

To run on server:

git clone https://github.com/talentappstore/imageGen.git
cd imageGen
docker build -t imagegen .
docker run -d -p 8081:8081 --restart unless-stopped imagegen

Images will now be served at (e.g. for a score of 77):

http://yourserver.com:8081/scoreWithIcon.png?score=77&label=A1

Areas for improvement:

• more image types
• add a signature param, so that only users with the generator's secret key can create working urls (we don't want miscreants hosting 52x32 porn images :)
• add varnish to cache images server-side
