title: Camera preview on small surfaceView not showing the whole camera output
body: <p>My app is showing the camera preview on one of my activities. I would like to show the camera preview but not taking the full screen, just inside a small box.</p>
  
  <p>The problem is that right now the image that i get from the camera is smaller that I want. For example, when I open it I can only see there my eyes and nose, but I would like to see my whole face.</p>
  
  <p>It's like my surfeceView is acting like a window in a house that only allows me to see part of the views outside. The idea is that in the surfaceView (that does not take the whole screen space) I get the whole camera output but resized in order to fit the surfaceView.</p>
  
  <p>Is that a problem with the camera preview size? Or should I somehow resize the camera output?</p>
  
  <p>Thanks in advance</p>
