title: Android register touch events on visible portion of image?
body: <p>I've currently been thinking about how I could register only touch events on the visible (non-transparent) parts of a .PNG image.</p>
  
  <p>-I've been testing around with AndEngine and it seems they have multiple options: I've tried any I could find to no avail.</p>
  
  <p>-I could very possibly create my own method of checking a given touched area's transparency I suppose, but not sure how much work/overhead that might create with 15-20 objects on screen being able to be touched..</p>
  
  <p>Any help is much appreciated!</p>
