        // resource bitmaps are imutable,
        // so we need to convert it to mutable one

        // text shadow
        paint.setShadowLayer(2f, 1f, 1f, Color.WHITE);

        int x = bitmap.getWidth() - 150;//bounds.width()) - 150;
        int y = bitmap.getHeight() - 27;//bounds.height()) - 30;
        // fill
        canvas.drawRect(x, y, x + 150, y + 27, paint);
