How do I create super / subscript in iText?

The following example you’ll see how to create a superscript and subscript text in the pdf document using iText. We can use the Chunk‘s class method called setTextRise(). A positive value will create a superscript text while a negative value will create a subscript text.

package org.kodejava.itextpdf;

import com.itextpdf.text.*;
import com.itextpdf.text.pdf.PdfWriter;

import java.io.FileNotFoundException;
import java.io.FileOutputStream;

public class SuperSubscriptDemo {
    public static void main(String[] args) {
        Document doc = new Document();
        try {
            PdfWriter.getInstance(doc, new FileOutputStream("SuperSubscript.pdf"));
            doc.open();

            Font small = FontFactory.getFont(FontFactory.HELVETICA, 5, Font.ITALIC);

            // Add some chunks into the doc object.
            doc.add(new Chunk("The quick brown  "));

            Chunk superscript = new Chunk("fox ");
            superscript.setTextRise(5f);
            superscript.setFont(small);
            doc.add(superscript);

            doc.add(new Chunk("jumps over the lazy "));

            Chunk subscript = new Chunk("dog");
            subscript.setTextRise(-5f);
            subscript.setFont(small);
            doc.add(subscript);
        } catch (DocumentException | FileNotFoundException e) {
            e.printStackTrace();
        } finally {
            doc.close();
        }
    }
}
