A watermark is a semitransparent text or an image placed behind the content of a document. In Word, you can add a watermark to protect the intellectual property of the document, for example to include a copyright symbol, author's name or company logo. Or you can use it to indicate the status of a document, such as "Draft", "Confidential", or "Final". This article will demonstrate how to add text watermarks and image watermarks to Word in Python using Spire.Doc for Python.

Add a Text Watermark to a Word Document in Python
Spire.Doc for Python provides the TextWatermark class to set a text watermark, and then you can add it to Word document through Document.Watermark property. The following are the detailed steps.
- Create a Document object.
- Load a sample Word document using Document.LoadFromFile() method.
- Create an instance of TextWatermark class.
- Set the text, font size, color and layout of the text watermark using the methods of TextWatermark class.
- Add the text watermark to the Word document using Document.Watermark property.
- Save the result document using Document.SaveToFile() method.
- Python
from spire.doc import *
from spire.doc.common import *
# Create a Document object
document = Document()
# Load a Word document
document.LoadFromFile("test.docx")
# Create a TextWatermark object
txtWatermark = TextWatermark()
# Set the format of the text watermark
txtWatermark.Text = "DO NOT COPY"
txtWatermark.FontSize = 65
txtWatermark.Color = Color.get_Red()
txtWatermark.Layout = WatermarkLayout.Diagonal
# Add the text watermark to document
document.Watermark = txtWatermark
#Save the result document
document.SaveToFile("Output/TextWatermark.docx", FileFormat.Docx)
document.Close()
Add an Image Watermark in a Word Document in Python
To set the image watermark, you can use the methods of PictureWatermark class. The following are the detailed steps.
- Create a Document object.
- Load a sample Word document using Document.LoadFromFile() method.
- Create an instance of PictureWatermark class.
- Load an image as the image watermark using PictureWatermark.SetPicture() method, and then set scaling as well as washout property of the image watermark.
- Add the image watermark to the Word document using Document.Watermark property.
- Save the result document using Document.SaveToFile() method.
- Python
from spire.doc import *
from spire.doc.common import *
# Create a Document object
document = Document()
# Load a Word document
document.LoadFromFile("test.docx")
# Create a PictureWatermark object
picture = PictureWatermark()
# Set the format of the picture watermark
picture.SetPicture("logo.png")
picture.Scaling = 100
picture.IsWashout = False
# Add the image watermark to document
document.Watermark = picture
#Save the result document
document.SaveToFile("Output/ImageWatermark.docx", FileFormat.Docx)
document.Close()
