Subject Re: Conversion from 0.23 to 1.00
Date Fri, 16 Sep 2011 13:50:53 GMT
Hi Theresa,

one way to crop an image is to carry it within a svg snippet:

<fo:instream-foreign-object width="100%" height="100%"
    content-width="scale-to-fit" content-height="scale-to-fit">
  <svg xmlns="http://www.w3.org/2000/svg"
       xmlns:xlink="http://www.w3.org/1999/xlink"
      width="50mm" height="50mm" viewBox="0 0 100 100">
    <clipPath id="myClip">
      <rect x="0" y="0" width="100" height="100"/>
    </clipPath>
    <g clip-path="url(#myClip)">
      <image x="-5" y="-5" width="130" height="130"
          xlink:href="image_url_here"/>
    </g>
  </svg>
</fo:instream-foreign-object>
