@Soren : you are right. But whatever may be the coordinate I want to get the color. for testing a feasible coordinate can be selected. – skmaran.nr.iras Feb 07 '11 at 12:51

If you know the page then take the image of the page:
PdfImportedPage page = writer.getImportedPage(reader, pageNum); // get the page of the PDF Image img = Image.getInstance(page); // wrap it in an image object
From there on convert the Image to a byte array and get your color at your coordinate.
