Add Polyline Annotation

Polyline annotations allow you to highlight a series of connected line segments in a PDF. Using PdfContentEditor, you can draw a polyline by specifying vertices coordinates, border style, page number, and annotation bounds. This is useful for visually representing paths, trends, or connections in diagrams and documents.

1. Create the PdfContentEditor object.
2. Bind the input PDF.
3. Configure Polyline properties.
4. Add the Polyline annotation.
5. Save the updated Document.
