title: Can we get height and width of image using sharp?
body: <p>I am using sharp to resize bulk of image. So I am resizing them to 500px by preserving their aspect ratio. Also I want to resize height to 500px and auto resize width if height is greater than with and vice versa. To do that I need to get image, height from Image buffer. I know there are pretty number of packages available to do so. But I was hoping if I can do that using sharp buffer itself.</p>
