I want to show an image from an URL with a certain width and height even if it has a different size ratio. So I want to resize (maintaining the ratio) and then cut the image to the size I want. I can resize with html img property and I can cut with background-image. How can I do both? Example: This image: Has the size 800x600 pixels and I want to show like an image of 200x100 pixels With img I can resize the image 200x150px: <img style="width: 200px; height: 150px;" src="http://i.stack.imgur.com/wPh0S.jpg"> That gives me this: <img style="width: 200px; height: 150px;" src="https://i.stack.imgur.com/wPh0S.jpg"> And with background-image I can cut the image 200x100 pixels. <div style="background-image: url('https://i.stack.imgur.com/wPh0S.jpg'); width:200px; height:100px; background-position:center;">&nbsp;</div> Gives me: <div style="background-image:url('https://i.stack.imgur.com/wPh0S.jpg'); width:200px; height:100px; background-position:center;">&nbsp;</div> How can I do both? Resize the image and then cut it the size I want?

.imgContainer {
  overflow: hidden;
  width: 200px;
  height: 100px;
}
.imgContainer img {
  width: 200px;
  height: 120px;
}
<div class="imgContainer">
  <img src="imageSrc" />
</div>

包含的div本质上是通过隐藏溢出来裁剪图像。

你可以使用Kodem的图片调整服务。您可以通过http调用调整任何图像的大小。可以在浏览器中随意使用,也可以在生产应用程序中使用。

上传图片到你喜欢的地方(S3, imgur等) 将其插入到您的专用API url(从我们的仪表板)

img {
  position: absolute;
  clip: rect(0px, 140px, 140px, 0px);
}
<img src="w3css.gif" width="100" height="140" />
<p class="crop"><a href="http://templatica.com" title="Css Templates">
    <img src="img.jpg" alt="css template" /></a></p> 

.crop {
    float: left;
    margin: .5em 10px .5em 0;
    overflow: hidden; /* this is important */
    position: relative; /* this is important too */
    border: 1px solid #ccc;
    width: 150px;
    height: 90px;
}
.crop img {
    position: absolute;
    top: -20px;
    left: -55px;
}

尝试使用clip-path属性:

剪切路径属性允许您将元素剪切为基本形状或 SVG源代码。 注意:clip-path属性将替换已弃用的剪辑 财产。

img { 宽度:150 px; 剪辑路径:插入(30px 35px); } < img src = " http://i.stack.imgur.com/wPh0S.jpg " >

这里有更多的例子。

有像Filestack这样的服务可以帮你做这件事。

它们获取你的图像url,并允许你使用url参数来调整它的大小。这很简单。

将图像大小调整为200x100,但保持纵横比后,图像将如下所示

整个url看起来像这样

https://process.filestackapi.com/AhTgLagciQByzXpFGRI0Az/resize=width:200/crop=d:[0,25,200,100]/https://i.stack.imgur.com/wPh0S.jpg

但重要的是

resize=width:200/crop=d:[0,25,200,100]
