title: draw circle on bitmap
body: <p>i've written an app that captures a picture and saves it on the sdcard. i then can load that image into an imageview to display it. i'd like to draw a circle on the bitmap before i display it. the code below displays the bitmap but no circle, any ideas why the circle is not there?</p>
  
  <p>thanks.</p>
  
  <pre><code>BitmapFactory.Options bfo = new BitmapFactory.Options();
          bfo.inSampleSize = 5;
          Bitmap bm = BitmapFactory.decodeByteArray(imageArray, 0, imageArray.length, bfo);
          Log.e(TAG, bm.toString());
          //imageview.setImageBitmap(bm);
  
  
          Bitmap bmOverlay = Bitmap.createBitmap(bm.getWidth(), bm.getHeight(), bm.getConfig());
          canvas = new Canvas(bmOverlay);
          Paint paint = new Paint();
          paint.setColor(Color.RED);
          canvas.drawBitmap(bm, new Matrix(), null);
          canvas.drawCircle(750, 14, 11, paint);
          imageview.setImageBitmap(bmOverlay);
