there is work around for doing this by setting the image at absolute position and setting the page size equal to background image and don't forget to put the image in proper dpi folder :)

private void setBackground(Document document) {
    ByteArrayOutputStream stream = new ByteArrayOutputStream();
    Bitmap bitmap = BitmapFactory.decodeResource(mContext.getResources(), R.drawable.background_img);
    bitmap.compress(Bitmap.CompressFormat.JPEG , 100, stream);
    Image img;
    try {
        img = Image.getInstance(stream.toByteArray());
        img.setAbsolutePosition(0, 0);

        document.add(img);
    } catch (BadElementException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (MalformedURLException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (DocumentException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

}
