title: Get drawable displayed size after scaling
body: <p>here's my problem:<br>
  How can get the displayed size of the drawable inside an ImageView in pixel after scalling, assuming that the ImageView size isn't equal to the scaled drawable?</p>
  
  <p>A lot of methods just return the original size of the Drawable or just the size of the ImageView.</p>
  
  <p>Here is a picture describing what I want :</p>

  <p>1 --> ImageView Size<br>
  2 --> The scaled image size that I want to get in px</p>
  
  <p>Thank you.</p>
