纵横比填充 - 正确的方式

I know, it has been asked before. The answers are insufficient although they are marked as correct.

我知道,之前有人问过。虽然它们被标记为正确,但答案还不够。

I need something that fills a container with an image by showing the most of the image, centers it and preserves its ratio. Should be ajquery-plugin, a angular-directive or plain JS.

我需要通过显示图像的大部分来填充带有图像的容器,使其居中并保留其比例。应该是ajquery-plugin,angular-directive或普通的JS。

<div ratio-fill>
  <img>
</div>

Of course should be enough where the script takes action then.

当然,在脚本采取行动的地方应该足够了。
