I am trying to add some annotation like highlight some text write a note in pdf or tiff but seems the option is not available. Not sure whether viewer supports annotations.
By default alfresco viewer as of now does not supporting annotation But you can integrate other viewer which is supporting annotation.
Such type of viewer is available called snowbound.
Snowbound Software's VirtualViewer® HTML5 Document Viewer
The Alfresco default viewer is PDF.js which is does not support either annotation and advanced viewing capabilities.
There is a powerful viewer (thanks to native document streaming) you may want to try > ARender
This universal content viewer enables users to easily comment any document format (PDF, Office, Image, Video…) with an ergonomic on any device incl. Mobiles.ARender conforms to the XFDF ISO annotations standard, including all types :
AnnotationExplorer helps users navigate through their documents from existing annotations, facilitating review and collaboration.Each annotation can have its own approval lifecycle, security settings and tracking.ARender also supports import from/export to various formats (incl. FDF & embedded in PDF).
