PDF Annotation Server
Document Engine includes support for importing, creating, removing, and flattening PDF annotations. It offers developers a robust API for programmatic annotation management, as well as integration with our client-side SDKs for manual annotation through a UI.
What Are Annotations?
Content displayed as a PDF page isn’t suitable for easy editing, but the PDF specification defines a comprehensive set of objects that can be added to PDF pages without changing the page content. These objects are called annotations, and their purpose ranges from marking up page content to implementing interactive features such as forms.
