<femerge>

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 result attribute and then accessing it in a <feMergeNode> child.

Usage context

Categories	Filter primitive element
Permitted content	Any number of the following elements, in any order: `<feMergeNode>`

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 in="SourceGraphic" 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);" />
  <rect x="40" y="40" width="100" height="100"
