Clipping path in SVG not working in Safari

问题

I've created a simple polygon in Illustrator and then created a clipping path (mask) in front of an image. I've exported it as an SVG file, and it renders perfectly in Chrome and Safari.

However, when I create an HTML file using the SVG data, it renders perfectly in Chrome but not Safari 6.0.2.

Not quite sure what I might be doing wrong; I've created examples of the SVG example (personal site) and the HTML (example on jsfiddle).

You must be running into a bug in Safari, instead of using use to apply the mask, just use the actual polygon element:

<svg version="1.1" id="Layer_1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px"
     width="700px" height="700px" viewBox="0 0 700 700" style="enable-background:new 0 0 700 700;" xml:space="preserve">
  <g>  

    <clipPath id="SVGID_2_">
      <polygon id="SVGID_1_" points="576.35,444.245 670.595,350 576.349,255.754 576.349,123.651 444.246,123.651 350,29.405 255.755,123.651 122.96,123.651 122.96,256.446 29.405,350.001 122.96,443.555 122.96,577.041 256.446,577.041 350,670.595 443.554,577.041 576.35,577.041"/>
    </clipPath>

    <g id="LwhyVN.tif" style="clip-path:url(#SVGID_2_);">
      <image style="overflow:visible;" width="1024" height="768" id="Layer_0_1_" xlink:href="http://fc05.deviantart.net/fs13/f/2007/071/9/e/Japanese_shiba_inu__shiba_dog__by_MogamiJ.jpg"  transform="matrix(0.8418 0 0 0.8418 27.5078 37.498)"></image>
    </g>

  </g>
</svg>

This works for me in Safari 6.

Also watch out if you have a base tag in your html as safari apparently adds the base to the id selector.

Safari isn't a huge fan of clipPaths in SVG. Instead, it works perfectly when embedded within an old-school <Object> element. In order to do that though, I needed to make use of PHP headers to define the correct Content-type which is application/xhtml+xml. Without it,all that is served is text/html, where Safari (and older versions of modern browsers) will not display SVG.

In order to use PHP with SVG, I needed to add two additions to my webservers config file. In Apache, I added the type psvg to my mime-type file so that the releveant line reads like: image/svg+xml svg svgz psvg

Next, I had to add an additional SVG-handler in the Apache config file, so that the relevant line reads like: AddType application/x-httpd-php .php .php4 .phtml .psvg so that any .psvg file is rendered as PHP.

So I created a new file called faces.psvg, and it looks like this:

<?php
    header("Content-type: image/svg+xml");
    print('<?xml version="1.0" encoding="iso-8859-1"?>');
?>
<svg version="1.1"> //your svg file data </svg>

I then created a new .php file called index.php, and it looks like this:

<html>
<head>
    <meta http-equiv="content-type" content="application/xhtml+xml; charset=utf-8" />
</head>
<body>
     <object type="image/svg+xml" data="faces.psvg" width="1120" height="800"></object>
</body>
</html>

and voilá, working svg clipping masks everywhere, even Mobile Safari.

I managed to fix this, used a :before and applied the clip and colour to that:

.field_captioned_carousel .teaser>.teasertextbg:before {
    content: '';
    position: absolute;
    left: 0;
    top: 0;
    right: 0;
    bottom: 0;
    -webkit-clip-path: polygon(70px 0%,100% 0,100% 100%,0 100%,0 70px);
    clip-path: polygon(50px 0%,100% 0,100% 100%,0 100%,0 50px);
    background-color:#ff0000;
}

You should wrap the clipPath element inside a defs element:

<defs><clipPath></clipPath></defs>
