Scale the sky result bitmap

ScaleBitmap.java

// Scale the bitmap to fit the view port
float scaleWidth = ((float) cameraSize.getWidth()) / notSkyBitmap.getWidth();
float scaleHeight = ((float) cameraSize.getWidth()) / notSkyBitmap.getHeight();
final Matrix matrix = new Matrix();
float scale = Math.min(scaleWidth, scaleHeight);
matrix.postScale(scale, scale);

// Create a scaled bitmap
Bitmap scaledNonSkyBitmap = Bitmap.createBitmap(notSkyBitmap, 0, 0,
    notSkyBitmap.getWidth(), notSkyBitmap.getHeight(), matrix, false);

// Draw the bitmap in bottom center.
int left = (cameraSize.getWidth() - scaledNonSkyBitmap.getWidth()) / 2;
int top = cameraSize.getHeight() - scaledNonSkyBitmap.getHeight();
canvas.drawBitmap(scaledNonSkyBitmap, left, top, new Paint());
