Index

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.

Like other filter primitives, it handles color components in the linearRGB {{glossary("color space")}} by default. You can use {{svgattr("color-interpolation-filters")}} to use sRGB instead.

  <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>
