Finally I got some success... here is what I did. Found it in an example. It
creates an exact copy of the PDF with a new logo in it. Just what I needed.
The only odd thing is I have to divide the image size by 2 to get it to a
reasonable size though. If I don't the image looks huge? ie.
img.scaleToFit(img.width() / 2, img.height() / 2);
Thanks for everyone's time!
PdfReader reader = new PdfReader("C:\\original.pdf");
PdfStamper stamper = new PdfStamper(reader, new
FileOutputStream("C:\\newPDF.pdf"));
Image img = Image.getInstance("C:\\_projects\\GPO\\logo.jpg");
img.scaleToFit(img.width() / 2, img.height() / 2);
img.setAbsolutePosition(470, 780);
int pageNumber = 1;
PdfContentByte cb = stamper.getOverContent(pageNumber);
cb.addImage(img);
stamper.close();
reader.close();

If you first flatten Final_PKI_logo.jpg it may work.
