Java IText: Superscript + Subscript
You can write text as superscript or subscript using the
Chunk class, and it's setTextRise()method. You use a positive text rise value for superscript, and a negative text rise value for subscript.
Here is a simple code example:
import com.itextpdf.text.Chunk;
import com.itextpdf.text.Document;
import com.itextpdf.text.DocumentException;
import com.itextpdf.text.pdf.PdfWriter;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
public class SuperSubScriptExample {
public static void main(String[] args) {
Document document = new Document();
try {
PdfWriter.getInstance(document,
new FileOutputStream("SuperSubScript.pdf"));
document.open();
Chunk normalText =
new Chunk("Normal text at normal y-location. ");
document.add(normalText);
Chunk superScript = new Chunk("Superscript");
superScript.setTextRise(5f);
document.add(superScript);
Chunk moreNormalText =
new Chunk(". More normal y-location text. ");
document.add(moreNormalText);
Chunk subScript = new Chunk("Subscript");
subScript.setTextRise(-5f);
document.add(subScript);
document.close();
} catch (DocumentException e) {
e.printStackTrace();
} catch (FileNotFoundException e) {
e.printStackTrace();
}
}
}
Here is what the generated document looks like:
