itext version

In this program we are going to find version of the iText jar file which is using to make a pdf file through the java program.

In this example we need iText.jar file, without this jar file we never compile our application . The packages we need to import is java.io.FileOutputStream, java.io.IOException, com.lowagie.text.Document, com.lowagie.text.DocumentException, com.lowagie.text.Paragraph, com.lowagie.text.Rectangle,com.lowagie.text.pdf.PdfWriter.

The java.io.FileOutputStream and java.io.IOException classes are used to create file and throw the exception, if there is any exception occurs while creating a file. The com.lowagie.text.Document class is used to create a document object, com.lowagie.text.DocumentException is used to throw exception if there is any exception. com.lowagie.text.Paragraph classes is used to make paragraph , com.lowagie.text.Rectangle classes is used to create object of Rectangle class which will be used for setting the left, right, top, bottom margin, com.lowagie.text.pdf.PdfWriter class is used to write the document on a pdf file.

To make the program for finding the iText version firstly we will make a class VersionPDF. Remember the name of the file should be such that, if any other person sees the example then just by seeing the name of the program he can understand what the program is going to do without seeing the code.

Inside this class declare the main method which must throws Exception. After that follow the simple steps find the version:

Create Rectangle object and set the length and width of the page.
Create Document object and inside the constructor of Document pass pageSize and four integer which set the left,right,top and bottom margin. The Document describes a document's page size, margins, and other important attributes. It works as a container for a document's chapters, sections, images, paragraphs, and other content.
Create object of PrintWiter to add the value to document for this we need to use getInstance() method, in which we pass two arguments document and FileOutputStream("VersionPDF.pdf").
Open the document.
Create a Paragraph that hold a paragraph of text, tells the PDF document writer to ensure. The Paragraph's text justify on both sides and adds the Paragraph to the previously created Document. Inside the constructor of Paragraph we have to pass a String .Create paragraph and add it to the document.
To find the version of iText use getVersion() method which is static. It is a method of Document.
Add next paragraph.
Close the document. The closing of the document is important because it flushes and closes the OutputStream instance.

The code of the program is given below:


import java.io.FileOutputStream;

import java.io.IOException;

import com.lowagie.text.Document;

import com.lowagie.text.DocumentException;

import com.lowagie.text.Paragraph;

import com.lowagie.text.Rectangle;

import com.lowagie.text.pdf.PdfWriter;

public class VersionPDF {

 public static void main(String[] args)throws Exception {

    System.out.println("Example of a Find version of iText");  

  Rectangle pageSize = new Rectangle(288, 720);

  Document document = new Document(pageSize, 36, 18, 72, 72);

    PdfWriter writer=PdfWriter.getInstance(document, 

    new FileOutputStream("VersionPDF.pdf")); 

  document.open();

  document.add(new Paragraph("Version Of iText--

    >>Rose India"));

  document.add(new Paragraph("This page was made using " +

    Document.getVersion()));  

  document.add(new Paragraph("-->>RoseIndai.net"));

  document.close();

  }

}

The output of the program is given below:
