在多边形点路径(svg)内调整图像大小并使其不被裁剪 [英] Resize image inside polygon point path(svg) and make it not clipped

问题描述

我要实现以下目标:

调整svg元素内的图像大小以使其完全适合多边形内，此外，该图像是完全可见的，不会被剪切(请参见jsfiddle).

Resize the image inside the svg element to perfectly fit inside a polygon, and furthermore that it is fully viewable, and not clipped ( see jsfiddle).

我经历了很多stackoverflow问题，但无法弄清楚:

I have gone through many stackoverflow questions but cannot figure it out:

代码:

<svg width="50%" height="50%" viewBox="0 0 25 10"  preserveAspectRatio="none">
      <defs>
          <pattern id="im1" width="100%" height="100%" preserveAspectRatio="none">
              <image  preserveAspectRatio="none" xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="http://dummyimage.com/600x400/abc" width="100%" height="100%"></image>
          </pattern>
      </defs>
       <polygon points="0,10 29, 10 10, 0" x="0" y="0" style="fill:url(#im1);"></polygon>
    
    </svg>

请参见 https://jsfiddle.net/f8ktzyLw/

有人可以指出我正确的方向吗?这是仅可以通过svg实现的，还是我需要JavaScript/画布?

Can someone point me in the right direction ? is this achievable with svg only or do i need JavaScript/Canvas ?

推荐答案

多边形的水平尺寸29px比viewBox ="0 0 25 10"大4px

Polygon size 29px horizontal is 4px larger than viewBox = "0 0 25 10"

我添加了一个灰色框，用于显示SVG画布的边界

I added a gray frame that shows the boundaries of the SVG canvas

<svg width="50%" height="50%" viewBox="0 0 25 10"  preserveAspectRatio="none" style="border:1px solid gray">
  <defs>
      <pattern id="im1" width="100%" height="100%" preserveAspectRatio="none">
          <image  preserveAspectRatio="none" xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="http://dummyimage.com/600x400/abc" width="100%" height="100%"></image>
      </pattern>
  </defs>
   <polygon points="0,10 29, 10 10, 0" x="0" y="0" style="fill:url(#im1);"></polygon>

</svg>

要使多边形完全适合SVG的画布，必须将SVG的大小水平增加4px viewBox ="0 0 29 10"

To make the polygon fully fit inside the canvas of the SVG, it is necessary to increase the size of the SVG horizontally by 4px viewBox="0 0 29 10"

<svg width="50%" height="50%" viewBox="0 0 29 10"  preserveAspectRatio="none" style="border:1px solid gray">
  <defs>
      <pattern id="im1" width="100%" height="100%" preserveAspectRatio="none">
          <image  preserveAspectRatio="none" xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="http://dummyimage.com/600x400/abc" width="100%" height="100%"></image>
      </pattern>
  </defs>
   <polygon points="0,10 29, 10 10, 0" x="0" y="0" style="fill:url(#im1);"></polygon>

</svg>

或者您可以保持 viewBox ="0 0 25 10 的尺寸不变，但是随后您需要将多边形的水平尺寸减小相同的 4px

Or you can leave the dimensions of the viewBox="0 0 25 10 unchanged, but then you need to reduce the horizontal size of the polygon by the same 4px

<svg width="50%" height="50%" viewBox="0 0 25 10"  preserveAspectRatio="none" style="border:1px solid gray">
  <defs>
      <pattern id="im1" width="100%" height="100%" preserveAspectRatio="none">
          <image  preserveAspectRatio="none" xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="http://dummyimage.com/600x400/abc" width="100%" height="100%"></image>
      </pattern>
  </defs>
   <polygon points="0,10 25, 10 10, 0" x="0" y="0" style="fill:url(#im1);"></polygon>

</svg>
