title: Customized camera view & rotation in Zxing for QR code?
body: <p>I am working with such a great library zxing to read QR code. I already got QR code successfully.</p>
  
  <p>Now, My application runs in landscape mode and camera takes the whole screen and red QR detection rectangle box is in the middle. I wanna change this to portrait mode &amp; replace the camera view only with the red QR detection rectangle box.</p>
  
  <p>I change CaptureActivity tag which is inside the zxing library manifest file.</p>
  
  <p><code>android:screenOrientation="portrait"</code>.</p>
  
  <p>But found nothing what I actually want. I don't know where I have to change/write code to get this.</p>
