Highlight in PdfDocumentViewer

[peterInStIngbert]

Is it possible to highlight areas (rectangle) directly in the PdfDocumentViewer and undo the highlighting?

A user should be able to select different predefined areas (rectangles)
e.g.
Area 1 = address
Area 2 = Customer number
Area 3 = Invoice number

Only one area should be highlighted at a time.
For example, if the user selects "customer number", area 2 should be highlighted, areas 1 and 3 are then not highlighted.
If the user then selects "address", area 1 should be highlighted and area 2 should no longer be highlighted.
