title: how does iOS scale up a non fullscreen launch image to show it as a fullscreen launch image
body: <p>iOS guidelines ask us to package 768 x 1004 (portrait launch image) or 1024 x 748 (landscape launch image) sized launch images for iPad irrespective of the fact whether the app is fullscreen or not. However if we intend to extend the duration of our full screen by showing the same launch image for some more time so that we can do the initialization in the backend, we tend to see a small drift (the launch image shown by us shifts by a small amount).</p>
  
  <p>This is because of the fact that scaling used by iOS to show the non fullscreen image is different from what when we display the image. </p>
  
  <p>Can someone help me fix this?</p>
