title: Rotate an image around an axis
body: <p>I have an image that I want to rotate, like a watch hand. The problem is that no matter what I'm putting in the pivot point (in the matrix.setrotate)  is still rotated the same. Here is my code:</p>
  
  <pre><code>c = holder.lockCanvas();
  matrix.setRotate((float) degre * 4, 500, 500);
  Bitmap to_rotate = Bitmap.createBitmap(watch_hand, 0, 0, watch_hand.getWidth(), watch_hand.getHeight(), matrix, false);
  c.drawARGB(255, 255, 255, 255);
  c.drawBitmap(background, 0, 0, null);
  c.drawBitmap(to_rotate, CENTER_X - 20 , CENTER_Y - height / 2 + 20, null);
  holder.unlockCanvasAndPost(c);
  </code></pre>
  
  <p>What can I do? </p>
  
  <p>I want the image to rotate at "CENTER_X, CENTER_Y.</p>
