Manage annotations
The Toolbox add-on lets you manage annotations in PDF documents. PDF annotations are elements that allow you to add comments, suggestions, and markup like shapes and highlights to PDFs. Annotations are not part of the page content as they are applied on the top of a page. In contrast to ordinary page content, many annotation types behave interactively in PDF viewers.
This functionality is part of the Toolbox add-on, a separate SDK that you can use with the same license key as the Pdftools SDK. To use and integrate this add-on, review Getting started with the Toolbox add-on and Toolbox add-on code samples.
The Toolbox add-on supports the following types of annotations:
Type | Annotation name |
---|---|
Text Markup | Highlight Popup StickyNote StrikeThrough Underline |
Shape | Ellipse Ink Line Polygon PolyLine Rectangle Squiggly |
Navigation | InternalLink WebLink |
Stamp | TextStamp CustomStamp |
File | FileAttachment |
