Then I guess you better start reading what we've already written on the topic and try to understand it.
We have already told you WHY the code you wrote won't work for most images in a PDF.
We have already told you what you need to do so solve it - in general terms.
We are NOT going to write your code for you.
BUT we WILL answer questions for you as you attempt to actually implement something based on our recommendations...

Subject: Re: [iText-questions] extract the stamped image from pdf
Hi Bruno/Leo,
It's urgent task that I need to complete in coming two days :(
I need to extract all format image from pdf document.
I tried with Bruno suggestion ImageXRefViewer.java class.
PdfReader chartReader = new PdfReader("MyPdf.pdf");
for (int i = 0; i < chartReader.getXrefSize(); i++) {
PdfObject pdfobj = chartReader.getPdfObject(i);
if (pdfobj != null && pdfobj.isStream()) {
PdfStream stream = (PdfStream) pdfobj;
PdfObject pdfsubtype = stream.get(PdfName.SUBTYPE);
//System.out.println("Stream subType: " + pdfsubtype);
if (pdfsubtype != null &&
pdfsubtype.toString().equals(PdfName.IMAGE.toString())) {
byte[] image = PdfReader.getStreamBytesRaw((PRStream)
stream);
Image image = Image.getInstance(imgBytes);
using this image object I need to retrieve the image
height,width and dpi i.e. image.getDpiX();
