Annotation module is a web application that runs in your browser with the help of javascript and can be accessed from anywhere.


Follow those recommendations for the best results:
Though we support all common web browsers, we strongly recommend using Google Chrome or Mozilla Firefox, because we use latest technologies to render annotations. We also advise you to use the latest version of web browser.
To work with large images and lots of annotations we recommend to use computer with hardware acceleration available. Check if your browser uses hardware acceleration here.
