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;"> </div> Gives me: <div style="background-image:url('https://i.stack.imgur.com/wPh0S.jpg'); width:200px; height:100px; background-position:center;"> </div> How can I do both? Resize the image and then cut it the size I want?

如果您正在使用<img>标记,那么Object-fit可能会帮助您
下面的代码将为您裁剪图像。你可以尝试一下合身的衣服
img {
object-fit: cover;
width: 300px;
height: 337px;
}

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]
.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。
我所做的是创建一个服务器端脚本,它将在服务器端调整大小和裁剪图片,这样它就会在互联网上发送更少的数据。
它相当简单,但如果有人感兴趣,我可以挖掘并发布代码(asp.net)
img {
position: absolute;
clip: rect(0px, 140px, 140px, 0px);
}
<img src="w3css.gif" width="100" height="140" />
