Add watermarks to Diagram documents Leave feedback
On this page
GroupDocs.Watermark adds watermarks to Visio diagrams as shapes placed on the background or foreground of the pages. Open the diagram and pass a DiagramShapeWatermarkOptions to add() with the desired placement_type.
NoteOpen Visio files with format auto-detection —Watermarker("diagram.vsdx")— rather than passingDiagramLoadOptions()to the constructor.

Use DiagramWatermarkPlacementType.FOREGROUND_PAGES to place the watermark in front of the page content instead. Watermarker.get_content() returns a DiagramContent exposing each page’s shapes and headers/footers — see Existing objects in diagrams.
