            TextWatermark textWatermark = new TextWatermark("Confidential", new Font("Arial", 36));
            textWatermark.ForegroundColor = Color.Red;
            textWatermark.Opacity = 0.5;
            textWatermark.RotationAngle = 45;

            // Add the watermark to all pages of the PDF
            watermarker.Add(textWatermark);
            
            // Save the watermarked PDF document
