Example

In the below example we have taken an image and displayed it in various ways.

package com.kscodes.examples.itext;

import java.io.FileOutputStream;

import com.itextpdf.text.Document;

import com.itextpdf.text.Image;

import com.itextpdf.text.pdf.PdfWriter;

public class ImageExample1 {

public static void main(String args[]) {

// Create a Document object

Document document = new Document();

try {

// Create a PdfWriter instance and use the document to write the pdf

// to a specified location

PdfWriter.getInstance(document, new FileOutputStream("K:\\Kscodes\\pdf\\itext-image.pdf"));

// open the document

document.open();

// Get instance of Image and then add it in document

Image image = Image.getInstance("K:\\Kscodes\\Images\\java_logo.png");

document.add(image);

// Image Rotation test

Image image1 = Image.getInstance("K:\\Kscodes\\Images\\java_logo.png");

image1.setRotationDegrees(45);

document.add(image1);

// Image scaling test

Image image2 = Image.getInstance("K:\\Kscodes\\Images\\java_logo.png");

image2.scaleToFit(75, 200);

document.add(image2);

// close the document

document.close();

System.out.println("PDF created at the location !!!");

} catch (Exception e) {

System.out.println("Exception occured :: " + e);

}
