A watermark is an image or text that when printed appears in the background of a document. The watermark text or image is faded so that it does not distract from the content of the document but is legible.
The property Document.Watermark returns a Watermark object.
To create a text watermark, assign the string that you want to display in the background of the document to the Watermark object's Text property.
To use an image as a watermark, assign an image file to the Watermark object's Image property.
To remove a watermark from a document, call the Watermark object's ClearWatermark method.
