Overview

Annotations are used to markup a PDF document without changing its original content.

The annotator package creates the Annotation object and an appearance stream, which is required to make the annotation look the same in all viewers.

• Text Markup(Highlight, Underline, Strikeout, Squiggly)
• Draw Shapes(Ellipse, Rectangle, Line, Polygon, Polyline)
• Redact
• Media

• Link
• Ink
