{{SVGRef}}

The <feMerge> SVG element allows filter effects to be applied concurrently instead of sequentially. This is achieved by other filters storing their output via the {{ SVGAttr("result") }} attribute and then accessing it in a {{ SVGElement("feMergeNode") }} child.

Usage context

{{svginfo}}

Example

SVG

<svg width="200" height="200" xmlns="http://www.w3.org/2000/svg">
  <filter id="feOffset" x="-40" y="-20" width="100" height="200">
    <feOffset in="SourceGraphic" dx="60" dy="60" />
    <feGaussianBlur stdDeviation="5" result="blur2" />
    <feMerge>
      <feMergeNode in="blur2" />
      <feMergeNode in="SourceGraphic" />
    </feMerge>
  </filter>

  <rect
    x="40"
    y="40"
    width="100"
    height="100"
    style="stroke: #000000; fill: green; filter: url(#feOffset);" />
</svg>
