We are happy to announce the release of the PDF.js Express utility API! This API enables users to perform actions that PDF.js Express alone does not support, such as merging and extracting annotations.
This is useful in scenarios where you want to save PDF annotations directly into the document, instead of a separate XFDF layer, or where you want to load annotations that exist in a document the user provides.
We also released a utility module to interact with these APIs here. This module handles all the license key and authentication steps required to use the API.
If there are any questions, please feel free to reply to this topic and we will do our best to anwser them.
