Answer 1

As far as I know this is not possible with iText (at least some time ago while I searched for a similar issue).

But you can use the PDFToImage from Apache PDFBox:

String [] args =  new String[7];
args[0] = "-startPage";
args[1] = "1";
args[2] = "-endPage";
args[3] = "1";
args[4] = "-outputPrefix";
args[5] = "MyJpgFile";
args[6] = "MyPdfFile";

PDFToImage.main(args);

It's easy to write a wrapper for this. Perhaps such a wrapper is available in PDFBox in the meantime.

Answer 2

Answering on my own question so that others can be benefited with it. After some research I found it and got the solution.

Have a look at this link.

PDFDocumentReader document = new PDFDocumentReader(<byteArraOfThePDF>);
PageDetail pageDetail = new PageDetail("<docIDanything>", "", <pagenumber>, "");
ResourceDetail det = document.getPageAsImage(pageDetail);

BufferedImage image = ImageIO.read(new ByteArrayInputStream(det.getBytes()));
File file = new File("d:/img2.jpg");
ImageIO.write(image, "jpg", file);
