            Description

            Attached image produces an NPE exception similar to the following:

            Exception in thread "main" java.lang.NullPointerException
            at org.icepdf.core.pobjects.Document.getPageImage(Document.java:1063)

            I did some debugging and found that statements:

            Document document = new Document();
            document.setFile(filePath);

            create a new document object, but getNumberOfPages() method of this object always return zero. Furthermore an exception is thrown when the following line executed thereafter:

            int number = document.getNumberOfPages();
            BufferedImage image = (BufferedImage) document.getPageImage( number, GraphicsRenderingHints.SCREEN, Page.BOUNDARY_CROPBOX, rotation, scale); <<< NPE thrown at this line
