PDFBox Adding Text

We can add Text content in the existing PDF document. This section describes how to add new text content to the existing PDF document. PDFBox library provides a PDPageContentStream class. This class contains the required methods to insert text, images, and other types of contents in a page of the PDF Document.

Follow the steps below to add text content in the existing PDF document -

import java.io.File; 
import java.io.IOException;
  
import org.apache.pdfbox.pdmodel.PDDocument; 
import org.apache.pdfbox.pdmodel.PDPage; 
import org.apache.pdfbox.pdmodel.PDPageContentStream; 
import org.apache.pdfbox.pdmodel.font.PDType1Font;
  
public class AddingContent {
   public static void main (String args[]) throws IOException {

      //Loading an existing document
      File file = new File("C:/PdfBox_Examples/my_doc.pdf");
      PDDocument document = PDDocument.load(file);
       
      //Retrieving the pages of the document 
      PDPage page = document.getPage(1);
      PDPageContentStream contentStream = new PDPageContentStream(document, page);
      
      //Begin the Content stream 
      contentStream.beginText(); 
       
      //Setting the font to the Content stream  
      contentStream.setFont(PDType1Font.TIMES_ROMAN, 12);

      //Setting the position for the line 
      contentStream.newLineAtOffset(25, 500);

      String text = "This is the sample document and we are adding content to it.";

      //Adding text in the form of string 
      contentStream.showText(text);      

      //Ending the content stream
      contentStream.endText();

      System.out.println("Content added");

      //Closing the content stream
      contentStream.close();

      //Saving the document
      document.save(new File("C:/PdfBox_Examples/new.pdf"));

      //Closing the document
      document.close();
   }
}
