How about what's around the lines ...

int size = 20;

UIScrollView *scrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)];

UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake((scrollView.center.x - (size / 2)), (scrollView.center.y - (size / 2)), size, size)];

[scrollView addSubview:imageView];
