Insert pages pdf
In this program we are going to insert a new blank pages
in pdf file through java program.
In this example we need iText.jar file, without this jar file we never compile our application . The package 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 changing the pdf version firstly we will make a class
NewpageInsertingPDF. 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 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 use
getInstance() method in which we pass two arguments document and FileOutputStream("NewPagePDF.pdf").
- Open 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 .Create paragraph and add it into document .
- Add the paragraph in the document.
- Use setPageEmpty(boolean pageEmpty) to make sure
that page is added. If setPageEmpty(false) then invoking newPage()
after blank
page will add a newPage().
- 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 NewpageInsetingPDF {
public static void main(String[] args)throws Exception {
System.out.println("Example of a PDF File to blank
pages and new page");
Rectangle pageSize = new Rectangle(288, 720);
Document document = new Document(pageSize, 36, 18, 72, 72);
PdfWriter writer=PdfWriter.getInstance(document,
new FileOutputStream("NewPagePDF.pdf"));
document.open();
document.add(new Paragraph("First Page-->>Rose India"));
document.add(new Paragraph("Next Two blank Pages"));
document.newPage();
writer.setPageEmpty(false);
document.newPage();
writer.setPageEmpty(false);
document.newPage();
document.add(new Paragraph("Last Page with some
data-->>RoseIndai.net"));
document.close();
}
}
