Link to a Pdf file

import java.awt.Color;
import java.io.FileOutputStream;

    document.newPage();
    document.add(new Paragraph("page 3"));
    writerB.resume();
    document.close();
  }
}





Remote Goto

import java.awt.Color;
import java.io.FileOutputStream;
import com.lowagie.text.Chunk;
import com.lowagie.text.Document;
import com.lowagie.text.Font;
import com.lowagie.text.FontFactory;

public class MainClass {
  public static void main(String[] args) throws Exception {
    Document document = new Document();
    PdfWriter writerA = PdfWriter.getInstance(document, new FileOutputStream("2.pdf"));
    PdfWriter writerB = PdfWriter.getInstance(document, new FileOutputStream("3.pdf"));
    document.open();
    Font font = FontFactory.getFont(FontFactory.HELVETICA, 12, Font.UNDERLINE, new Color(0, 0, 255));
    Paragraph p1 = new Paragraph("1");
    Chunk chunk = new Chunk(" 2", font);

    document.newPage();
    document.add(new Paragraph("page 3"));
    writerB.resume();
    document.close();
  }
}





Set Local Destination for chunk

import java.awt.Color;
import java.io.FileOutputStream;
import com.lowagie.text.Chunk;
import com.lowagie.text.Document;
import com.lowagie.text.Font;
import com.lowagie.text.FontFactory;
import com.lowagie.text.Paragraph;
import com.lowagie.text.pdf.PdfWriter;
public class MainClass {
  public static void main(String[] args) throws Exception {
    Document document = new Document();
    PdfWriter.getInstance(document, new FileOutputStream("2.pdf"));
    document.open();
    Paragraph p1 = new Paragraph("this is a test");
    p1.add(new Chunk(" another test ", FontFactory.getFont(FontFactory.HELVETICA, 12, Font.NORMAL,
        new Color(0, 0, 255))).setLocalGoto("jump"));
    p1.add("the lazy dog.");
    Paragraph p2 = new Paragraph("test");
    Paragraph p3 = new Paragraph("test 2");
    p3.add(new Chunk(" has jumped ", FontFactory.getFont(FontFactory.HELVETICA, 12, Font.NORMAL,
        new Color(0, 255, 0))).setLocalDestination(" cat "));
    p3.add(" dog.");
    document.add(p1);
    document.add(p2);
    document.add(p2);
    document.add(p2);
    document.add(p2);
    document.add(p2);
    document.add(p2);
    document.add(p2);
    document.add(p3);
    document.close();
  }
}





Set up PdfDestination

import java.io.FileOutputStream;
import com.lowagie.text.Document;
import com.lowagie.text.pdf.PdfContentByte;
import com.lowagie.text.pdf.PdfDestination;
import com.lowagie.text.pdf.PdfOutline;
import com.lowagie.text.pdf.PdfTemplate;
import com.lowagie.text.pdf.PdfWriter;
public class MainClass {
  public static void main(String[] args) throws Exception {
    Document document = new Document();
    PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream("2.pdf"));
    writer.setViewerPreferences(PdfWriter.PageModeUseOutlines);
    document.open();
    PdfContentByte cb = writer.getDirectContent();
    PdfTemplate template = cb.createTemplate(25, 25);
    template.moveTo(0, 13);
    template.lineTo(50, 13);
    template.stroke();
    cb.addTemplate(template, 87, 87);
    PdfDestination d1 = new PdfDestination(PdfDestination.XYZ, 300, 800, 0);
    PdfDestination d2 = new PdfDestination(PdfDestination.FITH, 500);
    PdfDestination d4 = new PdfDestination(PdfDestination.FITBV, 100);
    PdfDestination d5 = new PdfDestination(PdfDestination.FIT);
    PdfOutline root = cb.getRootOutline();
    PdfOutline out1 = new PdfOutline(root, d1, "root", true);
    PdfOutline out2 = new PdfOutline(out1, d2, "sub 1", false);
    new PdfOutline(out2, d4, "sub 2.1");
    new PdfOutline(out2, d5, "sub 2.2");
    document.close();
  }
}





Use SimpleNamedDestination

import java.io.FileOutputStream;
import java.util.HashMap;
import com.lowagie.text.Chunk;
import com.lowagie.text.Document;
import com.lowagie.text.Paragraph;
import com.lowagie.text.pdf.PdfReader;
import com.lowagie.text.pdf.PdfWriter;
import com.lowagie.text.pdf.SimpleNamedDestination;
public class MainClass {
  public static void main(String[] args) throws Exception {
    Document remote = new Document();
    PdfWriter.getInstance(remote, new FileOutputStream("remote.pdf"));
    remote.open();
    remote.add(new Paragraph("another"));
    remote.newPage();
    Paragraph p = new Paragraph("This paragraph contains a ");
    p.add(new Chunk("local destination").setLocalDestination("test"));
    remote.add(p);
    remote.close();
    PdfReader reader = new PdfReader("remote.pdf");
    HashMap map = SimpleNamedDestination.getNamedDestination(reader, false);
    SimpleNamedDestination.exportToXML(map, new FileOutputStream("remote.xml"), "ISO8859-1", true);
  }
}
