Adding the Images In Pdf in java example using iText


In this core java tutorial we will learn Adding the Images In Pdf (from local system or if you are working on web applications you may give path of image on server) using iText library - core java tutorial in Java with program and examples.


Follow these steps to Add Images in java using iText>
  1. Create FileOutputStream - the file in which created PDF will be stored
OutputStream fos = new FileOutputStream(new File(pdfFilePath));

  1. create Document (This document will represent the PDF document)
Document class is present in com.itextpdf.text.Document.
Document document = new Document();

  1. Attach PdfWriter to document,whenever any PDF element is added to document, it will get written to FileOutputStream

PdfWriter.getInstance(document, fos);

  1. open the document.
document.open();
                

  1. Now we will get the image from your local system or if you are working on web applications you may give path of image on server.
And create object/instance of com.itextpdf.text.Image like (Image image = Image.getInstance("E:/tiger.jpg"))

Then optionally you may set absolute position of image in PDF by using (               image.setAbsolutePosition(100f, 500f));
                
Then optionally you may set the image width and height using by using scaleAbsolute method OR
use the scaleAbsoluteWidth and scaleAbsoluteHeight methods to set width and height
                
//Scale image's width and height
      image.scaleAbsolute(200f, 200f);
                
OR use below two methods >
       //Scale image's height
       image.scaleAbsoluteWidth(200f);
       //Scale image's width
       image.scaleAbsoluteHeight(200f);
                
                
  1. add image to document
document.add(image);
  1. close document
document.close();
                

We will generate PDF files in java using iText library. PDF files can be generated dynamically in java using iText library.
