     Bitmap bitmapOrig = Bitmap.getBitmapResource("ICON.png");            
      // Create a Bitmap of arbitrary size
      int scaledX = 360;
      int scaledY = 415;
      Bitmap bitmapScaled = new Bitmap(scaledX, scaledY);
      bitmapOrig.scaleInto(bitmapScaled , Bitmap.FILTER_LANCZOS);                       
      bitmapOrig.scaleInto(bitmapScaled , Bitmap.FILTER_BILINEAR, Bitmap.SCALE_TO_FILL);                       
      BitmapField bitmapFieldScaled2 = new BitmapField(bitmapScaled , Field.FOCUSABLE);
     homeScreen.add(bitmapFieldScaled2);
