pdf section

     

In this program we are going to tell you how you can divide a pdf file into sections irrespective of the fact whether it exists or not.

To make a program over this, firstly we need to import some packages. Remember to make this program the first and foremost thing to remember is to place the iText.jar in WEB-INF/lib of your web application. The packages we were talking about are java.io.* for input output, java.awt.* and com.lowagie.text.pdf.*, and com.lowagie.text.*. These two package will help us to make and use pdf file in our program.

Now create a file named sectionPDF. Remember the name of the file should be such that the reader can understand what the program is going to perform. Inside the class declare a main method inside which we are going to write the logic of our program.

Firstly make a object of class Document. 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. 

Now create a document writer that writes the equivalent syntax for a document's content to a specific OutputStream. PdfWriter.getInstance() creates a PDF document writer that writes PDF syntax to concerned file by a FileOutputStream. If the pdf file doesn't exist then it will create a pdf file by that name.

Now open the document by document.open(). Make a Chapter and inside the constructor of Chapter create a Paragraph that houses a paragraph of text, tells the PDF document writer to ensure that the Paragraph's text is justified on both sides create a Section object and add the section to the previously created Chapter and add the Paragraph to the previously created Section. Inside the constructor of Paragraph we have passed one String. Add the Chapter object to the previously created Document. At last closes the document by using the document.close(). 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.*;
import java.awt.*;
import com.lowagie.text.*;
import com.lowagie.text.pdf.*;
public class sectionPDF{
public static void main(String arg[])throws Exception{
Document document=new Document();
PdfWriter.getInstance(document,new FileOutputStream("sectionPDF.pdf"));
document.open();
Chapter chapter=new Chapter(new Paragraph("Chapter1"),1);
Section section1=chapter.addSection(new Paragraph("Section1"));
section1.add(new Paragraph("Rose India"));
Section section2=chapter.addSection(new Paragraph("section2"));
section2.add(new Paragraph("roseinia.net"));
document.add(chapter);
document.close();
}
}

The output of the program is given below:
