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:
The output of the program is given below:
