如何使SVG充满以类似于CSS"background-size:cover"的方式进行操作 [英] How to make SVG "fill" act in a similar way to CSS "background-size: cover"

问题描述

我正在尝试创建一个SVG，该SVG使用特定的路径遮盖图像，但是，当我尝试使用图案填充区域时，图像无法覆盖整个区域.

I'm am trying to create an SVG which masks an image with a particular path however, when I try to fill the area using a pattern, the image does not cover the entire area.

预期

实际

在我的defs中，我正在定义模式:

In my defs I am defining the pattern:

<pattern id="image" patternUnits="userSpaceOnUse" width="83.38" height="100" x="0" y="0">
  <image xlink:href="http://goo.gl/kVVuy1" x="0" y="0" width="100%" height="100%" />
</pattern>

和形状:

<path id="shape" d="M80.4,0c0,33.3,0,66.7,0,100c-26.8,0-53.6,0-80.4,0c0,0,0-0.1,0-0.1 c3.3-12.3,6.5-24.6,9.8-37c0.9-21,1.9-41.9,2.8-62.9C35.2,0,57.8,0,80.4,0z" />

然后我添加形状:

<use xlink:href="#shape" fill="url(#image)"></use>

我使用的图像是动态资产(用户上传)，但是如果需要，我可以获取尺寸.

The image I'm using is dynamic asset (user uploaded), however I can obtain the dimensions if necessary.

任何可以解决此问题的解决方案都会有所帮助，我尝试使用带面罩的image，但没有运气.只要能显示蓝色背景图案而没有红色，那么我的问题就应该解决.

Any solution that would solve this issue would help, I tried using an image with a mask but had no luck. As long as the blue background pattern shows through and no red does then my problem should be solved.

推荐答案

要解决此问题，请将适当的preserveAspectRatio属性添加到<pattern>中的<image>，以告诉您希望图像进行缩放并切成薄片.

To fix this, add an appropriate preserveAspectRatio attribute to the <image> in your <pattern> to tell it that you want the image to be zoomed and sliced.

<pattern id="image" patternUnits="userSpaceOnUse" width="83.38" height="100" x="0" y="0">
  <image xlink:href="http://goo.gl/kVVuy1"
         x="0" y="0" width="100%" height="100%"
         preserveAspectRatio="xMinYMin slice"/>
</pattern>
