Repeating watermarks, also called multi-line watermarks, are a type of watermark that appears multiple times on a page of a Word document at regular intervals. Compared with single watermarks, repeating watermarks are more difficult to remove or obscure, thus offering a better deterrent to unauthorized copying and distribution. This article is going to show how to insert repeating text and image watermarks into Word documents programmatically using Spire.Doc for Java.

• Add Repeating Picture Watermarks to Word Documents in Java

Install Spire.Doc for Java

First of all, you're required to add the Spire.Doc.jar file as a dependency in your Java program. The JAR file can be downloaded from this link. If you use Maven, you can easily import the JAR file in your application by adding the following code to your project's pom.xml file.

Add Repeating Text Watermarks to Word Documents in Java

We can insert repeating text watermarks to Word documents by adding repeating WordArt to the headers of a document at specified intervals. The detailed steps are as follows:

• Create an object of Document class.
• Load a Word document using Document.loadFromFile() method.
• Create an object of ShapeObject class and set the WordArt text using ShapeObject.getWordArt().setText() method.
• Specify the rotation angle and the number of vertical repetitions and horizontal repetitions.
• Set the format of the shape using methods under ShapeObject class.
• Loop through the sections in the document to insert repeating watermarks to each section by adding the WordArt shape to the header of each section multiple times at specified intervals using Paragraph.getChildObjects().add(ShapeObject) method.
• Save the document using Document.saveToFile() method.

import com.spire.doc.Document;
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 insertRepeatingTextWatermark {
    public static void main(String[] args) {

        //Create an object of Document class
        Document doc = new Document();

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

        //Create an object of ShapeObject class and set the WordArt text
        ShapeObject shape = new ShapeObject(doc, ShapeType.Text_Plain_Text);
        shape.getWordArt().setText("DRAFT");

        //Specify the watermark rotating angle and the number of vertical repetitions and horizontal repetitions
        double rotation = 315;
        int ver = 5;
        int hor = 3;

        //Set the format of the WordArt shape
        shape.setWidth(60);
        shape.setHeight(20);
        shape.setVerticalPosition(30);
        shape.setHorizontalPosition(20);
        shape.setRotation(rotation);
        shape.setFillColor(Color.BLUE);
        shape.setLineStyle(ShapeLineStyle.Single);
        shape.setStrokeColor(Color.CYAN);
        shape.setStrokeWeight(1);

        //Loop through the sections in the document
        for (Section section : (Iterable) doc.getSections()
        ) {
            //Get the header of a section
            HeaderFooter header = section.getHeadersFooters().getHeader();
            //Add paragraphs to the header
            Paragraph paragraph = header.addParagraph();
            for (int i = 0; i < ver; i++) {
                for (int j = 0; j < hor; j++) {
                    //Add the WordArt shape to the header
                    shape = (ShapeObject) shape.deepClone();
                    shape.setVerticalPosition((float) (section.getPageSetup().getPageSize().getHeight()/ver * i + Math.sin(rotation) * shape.getWidth()/2));
                    shape.setHorizontalPosition((float) ((section.getPageSetup().getPageSize().getWidth()/hor - shape.getWidth()/2) * j));
                    paragraph.getChildObjects().add(shape);
                }
            }
        }

        //Save the document
        doc.saveToFile("RepeatingTextWatermark.docx");
        doc.dispose();
    }
}

Add Repeating Picture Watermarks to Word Documents in Java

Similarly, we can insert repeating image watermarks into Word documents by adding repeating pictures to headers at regular intervals. The detailed steps are as follows:

• Create an object of Document class.
• Load a Word document using Document.loadFromFile() method.
• Load a picture using DocPicture.loadImage() method.
• Set the text wrapping style of the picture as Behind using DocPicture.setTextWrappingStyle(TextWrappingStyle.Behind) method.
• Specify the number of vertical repetitions and horizontal repetitions.
• Loop through the sections in the document to insert repeating picture watermarks to the document by adding a picture to the header of each section at specified intervals using Paragraph.getChildObjects().add(DocPicture) method.
• Save the document using Document.saveToFile() method.

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.TextWrappingStyle;
import com.spire.doc.fields.DocPicture;

public class insertRepeatingPictureWatermark {
    public static void main(String[] args) {

        //Create an object of Document class
        Document doc = new Document();

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

        //Load a picture
        DocPicture pic = new DocPicture(doc);
        pic.loadImage("watermark.png");

        //Set the text wrapping style of the picture as Behind
        pic.setTextWrappingStyle(TextWrappingStyle.Behind);

        //Specify the number of vertical repetitions and horizontal repetitions
        int ver = 4;
        int hor = 3;

        //Loop through the sections in the document
        for (Section section : (Iterable) doc.getSections()
        ) {
            //Get the header of a section
            HeaderFooter header = section.getHeadersFooters().getHeader();
            //Add a paragraph to the section
            Paragraph paragraph = header.addParagraph();
            for (int i = 0; i < ver; i++) {
                for (int j = 0; j < hor; j++) {
                    //Add the picture to the header
                    pic = (DocPicture) pic.deepClone();
                    pic.setVerticalPosition((float) ((section.getPageSetup().getPageSize().getHeight()/ver) * i));
                    pic.setHorizontalPosition((float) (section.getPageSetup().getPageSize().getWidth()/hor - pic.getWidth()/2) * j);
                    paragraph.getChildObjects().add(pic);
                }
            }
        }

        //Save the document
        doc.saveToFile("RepeatingPictureWatermark.docx", FileFormat.Auto);
        doc.dispose();
    }
}

Effective screenshot:

A watermark in a Word document is a semitransparent text or image background that is used to highlight something important about the document, such as using text watermark to remind the reader that the document is confidential or just a draft and declaring copyright through a picture of your company. Sometimes watermarks can affect the readability of documents, and if we want to remove them, Spire.Doc for Java will be of great help. This article shows the detailed steps of removing watermarks from Word documents with the help of Spire.Doc for Java.

• Save the Word document using Document.saveToFile() method.

import com.spire.doc.*;

public class removeWatermark {
    public static void main(String[] args) {


        //Create an object of Document
        Document document = new Document();

        //Load a Word document from disk
        document.loadFromFile("D:/testp/test.docx");

        //Set the watermark value to null to remove the watermark
        document.setWatermark(null);

        //Save the Word document
        String output = "D:/javaOutput/removeWatermark.docx";
        document.saveToFile(output, FileFormat.Docx_2013);

        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 );
    }
