title: Bitmap's bounds in Android Studio
body: <p>My question is: a bitmap had to be square or is possible delete the invisible parts around the colored image? I have a bitmap in a SurfaceView with an hand in the center and i want calculate the bounds of this hand deleting the invisible around it, cause i have problems with the onClick Method. Without calculate every X and Y, is possible know the bounds of the hand with a Method or other things? Thanks in advance.</p>
