CSS显示图像调整大小和裁剪

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;
}

其他回答

.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。

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]

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)

<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;
}

在裁剪类中，放置你想要显示的图像大小:

.crop {
    width: 282px;
    height: 282px;
    overflow: hidden;
}
.crop span.img {
    background-position: center;
    background-size: cover;
    height: 282px;
    display: block;
}

html看起来像这样:

<div class="crop">
    <span class="img" style="background-image:url('http://url.to.image/image.jpg');"></span>
</div>
