                    "launchscreen.png");
            Bitmap bmp = BitmapFactory.decodeStream(inputStream);
            ByteArrayOutputStream stream = new ByteArrayOutputStream();
            bmp.compress(Bitmap.CompressFormat.PNG, 100, stream);
            Image signature;
            signature = Image.getInstance(stream.toByteArray());
            signature.setAbsolutePosition(400f, 150f);
            signature.scalePercent(100f);
            document.add(signature);
                    document.close();
        } catch (MalformedURLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
