Add a Text Watermark to Word

The detailed steps are as follows:

• Create a Document instance.
• Load a sample Word document using Document.loadFromFile() method.
• Get the first section using Document.getSections().get() method.
• Create a TextWatermark instance.
• Set the text, font size, color and layout of the text watermark using the methods offered by TextWatermark class.
• Add the text watermark to sample document using Section.getDocument().setWatermark() method.
• Save the document to file using Document.saveToFile() method.

import com.spire.doc.*;
import com.spire.doc.documents.WatermarkLayout;
import java.awt.*;

public class WordTextWatermark {
    public static void main(String[] args) {
        //Create a Document instance
        Document document = new Document();

        //Load a sample Word document
        document.loadFromFile("Sample.docx");

        //Get the first section
        Section section = document.getSections().get(0);

        //Create a TextWatermark instance
        TextWatermark txtWatermark = new TextWatermark();

        //Set the format of the text watermark
        txtWatermark.setText("Confidential");
        txtWatermark.setFontSize(40);
        txtWatermark.setColor(Color.red);
        txtWatermark.setLayout(WatermarkLayout.Diagonal);

        //Add the text watermark to document
        section.getDocument().setWatermark(txtWatermark);

        //Save the document to file
        document.saveToFile("out/result.docx", FileFormat.Docx);
    }

}

Add an Image Watermark to Word

The detailed steps are as follows:

• Create a Document instance.
• Load a sample Word document using Document.loadFromFile() method.
• Create a PictureWatermark instance.
• Load an image as the image watermark using PictureWatermark.setPicture() method, and then set scaling as well as washout property of the image watermark using PictureWatermark.setScaling() method and PictureWatermark.isWashout() method.
• Add the image watermark to sample document using Document.setWatermark() method.
• Save the document to file using Document.saveToFile() method.

import com.spire.doc.*;


public class WordImageWatermark {
    public static void main(String[] args)  throws Exception{
        //Create a Document instance
        Document document = new Document();

        //Load a sample Word document
        document.loadFromFile("Sample.docx");

        //Create a PictureWatermark instance
        PictureWatermark picture = new PictureWatermark();

        //Set the format of the picture watermark
        picture.setPicture("logo.png");
        picture.setScaling(100);
        picture.isWashout(false);

        //Add the image watermark to document
        document.setWatermark(picture);

        //Save the result file
        document.saveToFile("out/result2.docx",FileFormat.Docx );
