title: Easy way to rotate an image as ByteArray in another byteArray without drawing it
body: <p>I'm looking for an easy way to rotate a byteArray in a specific angle (not jut 90°, 180°, 270°) but all solutions I can find finish with g2D.drawImage(). I don't want to draw the image but only modify a byteArray.</p>
  
  <p>This might be really simple and maybe it only miss me the correct keywords to find relevant answers.</p>
  
  <p>Any Help appreciated, Class name, Tutorials, code extracts...
  thanks :-)</p>
