Creating the Subscript and Superscript

In this section, you will learn how we can create the subscript and superscript. iText api provides a setTextrise(float value1) method to set the position of text. We can set float value as positive or negative .Positive value is used for Superscript

Creating the Subscript and Superscript    

     

In this section, you will learn how we can create  the subscript and superscript.  iText api provides a setTextrise(float value1) method to set the position of text. We can set  float value as positive or negative .Positive value is used for  Superscript and negative value used for subscript.  

Code Description:
The setTextRise(float f) method is used to set subscript and superscript. The more about setTextRise(float rise)  

setTextRise:

public Chunk setTextRise(float rise)is used to sets the text displacement relative to the baseline. Positive values rise the text, negative values lower the text. It can be used to implement sub/superscript. 

One more method to getTextRise is:

getTextRise
public float getTextRise()is used to gets the text displacement relatiev to the baseline.

 

The code of the program is given below:

import java.awt.Color;
import java.io.FileOutputStream;
import java.io.IOException;
import com.lowagie.text.Chunk;
import com.lowagie.text.Document;
import com.lowagie.text.DocumentException;
import com.lowagie.text.pdf.PdfWriter;

public class exampleOfSubSupScript {  
  public static void main(String[] args)throws Exception {
  System.out.println("Sub- and Superscript");  
  Document document = new Document();
  PdfWriter.getInstance(document,new 
FileOutputStream
("SubSupScriptPDF.pdf"));
  document.open();  
  Chunk c1,c2,c3;
  c1 = new Chunk("Rose");
  c1.setTextRise(7.0f);
  document.add(c1);
  c2 = new Chunk("India");
  c2.setTextRise(3.0f);
  document.add(c2);
  c3 = new Chunk(".net");
  c3.setTextRise(-2.0f);
  document.add(c3);
 document.close();
 }
}

The output of the program is given below:
