Annotation capabilities in PDF Viewer components allow users to interact with documents through visual and textual markup, supporting review, collaboration, and documentation processes. Tools such as Line, Rectangle, and Free text help highlight structure and add clarity, while Sticky note and Stamp annotations provide contextual feedback and status indicators. By embedding these capabilities directly into a viewer, applications can offer a cohesive experience for editing and reviewing PDFs without requiring external software.

Common annotations include:

Ellipse annotations offer a circular or oval shape tool for highlighting regions in a less rigid form than rectangular annotations.
Free text annotations let users insert editable text anywhere on the page for inline commentary or corrections.
Freehand draw (Ink) annotations enable natural, pen-like input for signatures, sketches, or handwritten notes.
Line annotations allow users to draw straight connectors or highlights between points, often used for pointing out relationships or alignment.
Rectangle annotations provide a way to frame areas of interest, making it useful for emphasizing sections of a page.
Stamp annotations apply predefined or custom labels, such as approval or review statuses, directly onto the document.
Sticky note annotations add comment markers that can store detailed feedback without cluttering the document visually.
