hajar,
The document viewer demo itself does not have a burn or save annotations. You need to implement them by yourself. The burning can be done using Burn method and the saving can be done using Save method. You can read more about Burn method here:
https://www.leadtools.com/help/leadtools/v19/dh/javascript/ac/leadtools.annotations.core~leadtools.annotations.core.annrenderingengine~burn.html

You can read more about Save method here:

You can also use our HTML5 Annotations Demo's project as a reference to see what you need to add to the Document Viewer's code in order to be able to add burn and save abilities to the project. The Annotations project can be found here:
[LEADTOOLS 19]\Examples\JS\AnnotationsDemo

The Document Viewer project can be found here:

You can also refer to the following forum post which has a project that shows how to burn annotations on multi-pages at the server side:
