居中 owl-carousel，其中每个图像具有相同的高度并保持其纵横比

Question

有没有一种方法可以创建一个居中的owl-carousel，其中每个图像具有相同的高度而不丢失其纵横比？

我尝试用 JS/jQuery 计算图像大小，但 owl-carousel 的计算结果一团糟。 CSS 的结果相同。示例 (JSFiddle):

$(document).ready(function () {
    $('.loop').owlCarousel({
        center: true,
        items: 3,
        loop: true,
        margin: 20
    });
});

.owl-carousel .owl-stage {
  height: 150px;
}

.owl-carousel .owl-item {
  height: 100%;
}

.owl-carousel .owl-item .item {
  height: 100%;
}

.owl-carousel .owl-item img {
  height: 100% !important;
  width: auto !important;
  margin: 0 auto;
}

<link rel="stylesheet" type="text/css" href="https://owlcarousel2.github.io/OwlCarousel2/assets/owlcarousel/assets/owl.carousel.min.css">
<link rel="stylesheet" type="text/css" href="https://owlcarousel2.github.io/OwlCarousel2/assets/owlcarousel/assets/owl.theme.default.min.css">
<script type="text/javascript" src="https://owlcarousel2.github.io/OwlCarousel2/assets/vendors/jquery.min.js"></script>
<script type="text/javascript" src="https://owlcarousel2.github.io/OwlCarousel2/assets/owlcarousel/owl.carousel.js"></script>
<div class="loop owl-carousel owl-theme">
    <div class="item"><img src="http://via.placeholder.com/320x460/ff0000/000000?text=IMG 01" /></div>
    <div class="item"><img src="http://via.placeholder.com/460x320/00ffff/000000?text=IMG 02" /></div>
    <div class="item"><img src="http://via.placeholder.com/100x80/00ff00/000000?text=IMG 03" /></div>
    <div class="item"><img src="http://via.placeholder.com/50x100/ff00ff/000000?text=IMG 04" /></div>
    <div class="item"><img src="http://via.placeholder.com/70x80/ffff00/000000?text=IMG 05" /></div>
</div>

当前div/image应该是

在旋转木马的中央，
与所有其他项目具有相同的高度
保持纵横比并且
与上一项或下一项并排。

如果元素比视口大，那么它就会被剪切。

是否有一种方法可以通过 owl-carousel 实现这一目标？

我在 SO 上检查了其他一些类似的问题，但据我所知，它们的重点各不相同：

Image slider: maintaining equal height for all images while keeping slider responsive
```
 // overrides the aspect ratio
```
Owl Carousel align each item vertically when their height not equal
```
 // not the same height of each item*
```

我刚刚仔细检查了 auto-height demo...

To enable use autoHeight: true. At the moment works only with 1 item on screen. The plan is to calculate all visible items and change height according to highest item.

好像还没有这个选项

如果您的所有图片都具有相同的高度 - 尝试添加 autoWidth: true:

$(document).ready(function () {
  $('.owl-carousel').owlCarousel({
      center: true,
      margin:10,
      loop:true,
      autoWidth:true,
      items:4
  })
});

.owl-carousel .owl-stage {
  height: 200px;
}

.owl-carousel .owl-item {
  height: 100%;
}

.owl-carousel .owl-item .item {
  height: 100%;
}

.owl-carousel .owl-item img {
  height: 100% !important;
  width: auto !important;
  margin: 0 auto;
}
