parameters:

dx: offset for x

dy: offset for y

in: first picture

result: name for raster created

Example of code:

<defs>
   <filter id="MyFilter" filterUnits="userSpaceOnUse" x="0" y="0" width="400" height="400">
      <feImage xlink:href='memo.svg' result='pict1'/>
      <feOffset dx="2" dy="2" in="pict1" result='pict2'/>
      <feMerge>
         <feMergeNode in="pict1"/>
         <feMergeNode in="pict2"/>
      </feMerge>
   </filter>
</defs>
<use filter="url(#MyFilter)" x='0' y='0'/>
