Java - Add Text Watermark or Image Watermark to Word Documents

A watermark is a faded background image that displays behind the text in a document. It can be used to indicate a document’s status (confidential, draft, etc.) or to add a company logo. In this article, I am going to show you how to add text or image watermark to Word documents by using Free Spire.Doc for Java.

Installing Spire.Doc.jar

If you create a Maven project, you can easily import the jar in your application using the following configurations. For non-Maven projects, download the jar file from this link and add it as a dependency in your application.

Example 1. Add one-line text watermark to Word

import com.spire.doc.Document;
import com.spire.doc.FileFormat;
import com.spire.doc.TextWatermark;
import com.spire.doc.documents.WatermarkLayout;

import java.awt.*;

public class InsertTextWatermark {

    public static void main(String[] args) {

        //Create a Document object
        Document document = new Document();

        //Load a Word document
        document.loadFromFile("C:\\Users\\Administrator\\Desktop\\sample.docx");

        //Create a TextWatermark object
        TextWatermark txtWatermark = new TextWatermark();
       
        //Set text of the watermark
        txtWatermark.setText("Confidential");
        txtWatermark.setFontSize(60);
        txtWatermark.setColor(Color.darkGray);
        txtWatermark.setLayout(WatermarkLayout.Diagonal);

        //Apply the watermark to the document
        document.setWatermark(txtWatermark);

        //Save the document
        document.saveToFile("InsertTextWatermark.docx", FileFormat.Docx );
    }
}

Example 2. Add multi-line text watermark to Word

import com.spire.doc.Document;
import com.spire.doc.FileFormat;
import com.spire.doc.HeaderFooter;
import com.spire.doc.Section;
import com.spire.doc.documents.Paragraph;
import com.spire.doc.documents.ShapeLineStyle;
import com.spire.doc.documents.ShapeType;
import com.spire.doc.fields.ShapeObject;

import java.awt.*;

public class InsertMultiLineTextWatermark {

    public static void main(String[] args) {

        //Create a Document object
        Document doc = new Document();

        //Load the sample document
        doc.loadFromFile("C:\\Users\\Administrator\\Desktop\\sample.docx");

        //Create a shape
        ShapeObject shape = new ShapeObject(doc, ShapeType.Text_Plain_Text);
        shape.setWidth(100);
        shape.setHeight(30);

        //Set the text, position and style of the shape
        shape.setVerticalPosition(10);
        shape.setHorizontalPosition(20);
        shape.setRotation(325);
        shape.getWordArt().setText("Confidential");
        shape.setFillColor(Color.darkGray);
        shape.setLineStyle(ShapeLineStyle.Single);
        shape.setStrokeColor(new Color(192, 192, 192, 255));
       
        //Declare two variables
        Section section;
        HeaderFooter header;
        Paragraph paragraph;

        //Loop through the sections in the document
        for (int n = 0; n < doc.getSections().getCount(); n++) {

            //Get the specific section
            section = doc.getSections().get(n);

            //Get the header of section
            header = section.getHeadersFooters().getHeader();

            for (int rowNum = 0; rowNum < 4; rowNum ++) {

                //Add a paragraph to header
                paragraph = header.addParagraph();
                for (int colNum = 0; colNum < 3; colNum++) {

                    //Add the shape to various positions
                    shape = (ShapeObject) shape.deepClone();
                    shape.setVerticalPosition(50 + 150 * rowNum);
                    shape.setHorizontalPosition( 150 * colNum);
                    paragraph.getChildObjects().add(shape);
                }
            }
        }
       
        //Save to file
        doc.saveToFile("MultiLineTextWatermark.docx", FileFormat.Docx_2013);
    }
}

Example 3. Add an image watermark to Word

import com.spire.doc.Document;
import com.spire.doc.FileFormat;
import com.spire.doc.PictureWatermark;

public class InsertImageWatermark {

    public static void main(String[] args) {

        //Create a Document object
        Document document = new Document();

        //Load a Word document
        document.loadFromFile("C:\\Users\\Administrator\\Desktop\\sample.docx");

        //Create a PictureWatermark object and set the image path
        PictureWatermark picture = new PictureWatermark();
        picture.setPicture("C:\\Users\\Administrator\\Desktop\\company-logo.png");
        picture.isWashout(false);
        picture.setScaling(100);

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

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