// Specify an absolute or relative path to your document. Ex: @"C:\Docs\protected-document.docx"
string filePath = "protected-document.docx";
using (Watermarker watermarker = new Watermarker(filePath, loadOptions))
{
// use watermarker methods to manage watermarks in the document
TextWatermark watermark = new TextWatermark("Test watermark", new Font("Arial", 12));
watermarker.Add(watermark);
watermarker.Save("protected-document.docx");
