PDFBox Adding Multiple Lines
In the previous section, we discussed how to add text content to the pages of a PDF document. The previous program writes the only single line in a page. If we want to insert more than one line in the page than it will not allow and end inserting text after ending the line.
To add multiple lines in a PDF document we need to use the setLeading() method and after finishing each line we use newline() method to insert text from a new line.
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 AddMultipleLines {
public static void main(String args[]) throws IOException {
//Loading an existing document
File file = new File("C:/PdfBox_Examples/my_pdf.pdf");
PDDocument doc = document.load(file);
//Creating a PDF Document
PDPage page = doc.getPage(1);
PDPageContentStream contentStream = new PDPageContentStream(doc, page);
//Begin the Content stream
contentStream.beginText();
//Setting the font to the Content stream
contentStream.setFont( PDType1Font.TIMES_ROMAN, 16 );
//Setting the leading
contentStream.setLeading(14.5f);
//Setting the position for the line
contentStream.newLineAtOffset(25, 725);
String text1 = "This is an example of adding text to a page in the pdf document.
we can add as many lines";
String text2 = "as we want like this using the ShowText() method of the
ContentStream class";
//Adding text in the form of string
contentStream. ShowText(text1);
contentStream.newLine();
contentStream. ShowText(text2);
//Ending the content stream
contentStream.endText();
System.out.println("Content added");
//Closing the content stream
contentStream.close();
//Saving the document
doc.save(new File("C:/PdfBox_Examples/new.pdf"));
//Closing the document
doc.close();
}
}
