How to wrap image in the pdf file

     

In this program we are going to tell you how we can insert a image  and wrap it according to your own style in a pdf file irrespective of the fact whether it exists or not. If it exists, fine otherwise it will get automatically created.  

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 directory of your web application. Without this .jar the application will not run.  Its a must to import this .jar file in the above directory.The packages we were talking about are java.io.* for input output, 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 imagesWrapPDF. Remember the name of the file should be such that the reader can easily  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 Document class. This class 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().  Image.getInstance() gets the image. After that add the content to the document. 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 and adds the Paragraph to the previously created Document. Inside the constructor of Paragraph we have passed a String . We have written a paragraph inside the Paragraph constructor so that you can understand what is happening. Now add the object of Paragraph in the 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 com.lowagie.text.*;
import com.lowagie.text.pdf.*;

public class imagesWrapPDF{
public static void main(String arg[])throws Exception{
Document document=new Document();
PdfWriter.getInstance(document,
new FileOutputStream("imagesWrapPDF.pdf"));
document.open();
Image image = Image.getInstance ("devi.jpg");
Paragraph para=new Paragraph("RoseIndia.net
