Support for PDF Document Annotations

The PDF Viewer control can show only visible markup annotations. In the following image, the current page contains two annotations: a file attachment and a free text annotation.

Supported markup annotation types include:

  • Free text.

  • Text markup (that is, highlight, underline, strikeout, and squiggly-underline).

  • Square and circle.

  • Line, polygon, and polyline.

  • File attachment.

A file attachment annotation allows you to open or save a copy of the attachment associated with a specific page.

You can manage the annotation accessibility via the control’s OptionsSelection.Annotations property.

Note

The VCL PDF Viewer also provides limited support for rubber stamp, caret, and ink annotations.
