pdf landscape
In this free tutorial we are going to tell you about landscape
portrait in iText. iText is a framework for creating pdf files in java.
In this tutorial you will know more about the landscape portrait.
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. Without this jar file our application will not run. The packages
which we need to import are java.io.* for input
output, java.awt.* package, 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 landscapeportraitPDF. 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 for you by that name.
Now open the document by document.open().
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.
Inside the constructor of Paragraph we have passed a String . Now use the
method setPageSize to set the page size of the pdf file. To make a new page use
newPage() method and add it to 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 com.lowagie.text.*;
import com.lowagie.text.pdf.*;
public class landscapeportraitPDF
{
public static void main(String arg[])throws Exception
{
Document document = new
Document(PageSize.A4.rotate());
PdfWriter.getInstance(document,new
FileOutputStream("landscapeportraitPDF.pdf"));
document.open();
document.add(new Paragraph("landscape format, just
make the height smaller than the width."));
document.setPageSize(PageSize.A4);
document.newPage();
document.add(new Paragraph("This is portrait again"));
document.close();
}
}
