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?

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)

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。

如果你正在使用Bootstrap，尝试使用{background-size: cover; }对于<div>可能给div一个类说<div class="example" style=url('../your_image.jpeg');>所以它变成 div.example { background-size:封面}

<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>

img {
  position: absolute;
  clip: rect(0px, 140px, 140px, 0px);
}

<img src="w3css.gif" width="100" height="140" />
