css - ie中的图像是像素化的

Question

我已经将 png 图像上传到网站，它们在 firefox、chrome 和 safari 中看起来很完美，但在 ie 中看起来很糟糕。我已经从 photoshop 中保存了这些文件，它们在图像大小下有一个功能，让您可以选择将图像设置为:双三次自动、双三次锐化、双三次平滑、双三次、双线性和最近邻。这些有帮助吗？

html:

<ul class="social">
  <li><a target="_blank" href="https://plus.google.com/+ToadhallcottagesCoUk/posts"><img onmouseout=this.src='/images/googleplusgrey-flat.png' onmouseover=this.src='/images/googleplus-flat.png' src="/images/googleplusgrey-flat.png" width="38" height="38" alt="Toad Hall Cottages Google Plus Page"</a></li>
  <li><a target="_blank" href="http://www.twitter.com/thcottages"><img onmouseout=this.src='/images/twittergrey-flat.png' onmouseover=this.src='/images/twitter-flat.png' src="/images/twittergrey-flat.png" width="38" height="38" alt="Toad Hall Cottages on Twitter" /></a></li>
  <li><a target="_blank" href="http://www.facebook.com/holidaycottages"><img <img onmouseout=this.src='/images/facebookgrey-flat.png' onmouseover=this.src='/images/facebook-flat.png'  src="/images/facebookgrey-flat.png" width="38" height="38" alt="Toad Hall Cottages Facebook page"/></a></li>

</ul>

CSS:

img.icon { 
  vertical-align: middle; 
  margin-right: 8px; 
  margin-left: 2px;
  image-rendering:optimizeSpeed;             /* Legal fallback */
  image-rendering:-moz-crisp-edges;          /* Firefox        */
  image-rendering:-o-crisp-edges;            /* Opera          */
  image-rendering:-webkit-optimize-contrast; /* Safari         */
}

Answer 1

旧的IE方法是:

-ms-interpolation-mode: bicubic;

这没有很好的记录。
