如何防止 flexbox 水平拉伸我的图像？

Question

我看到这个关于 flexbox 垂直拉伸图像的问题，并应用 align-self: center 修复它： Why does flexbox stretch my image?

但是，我的图像水平拉伸存在问题： https://jsfiddle.net/qnnpxskk/

HTML：

<div class="wrapper">
  <div class="inner">
    <div class="row">
      <img src="https://www.wired.com/wp-content/uploads/2015/11/google-tensor-flow-logo-F.jpg">
    </div>
    <div class="row">
      <img src="https://www.wired.com/wp-content/uploads/2015/11/google-tensor-flow-logo-F.jpg">
    </div>
  </div>
</div>

CSS：

.wrapper{
  width: 600px;
  height: 900px;
  background: white;
}
.inner{
  display: flex;
  flex-direction: column;
}
.row{
  max-height: 100px;
  margin: 20px;
  display: flex;
  flex-direction: row;
  background: red;
}
.row img{
  max-height: 100%;
}

我尝试的一切似乎都无法使图像不被拉伸。我希望图像是父级的 100% 高度和保持原始纵横比的宽度。

更新css部分

.row img{
  max-height: 100%;
  object-fit:contain; /* Add this You can change it as your need */
}
.inner{
  display: flex;
  flex-flow:column nowrap;
  justify-content:flex-start;
}
.wrapper{
  width: 100%; /*Add this*/
  height: 900px;
  background: white;
}
