The result attribute defines the assigned name for this filter primitive. If supplied, then graphics that result from processing this filter primitive can be referenced by an in attribute on a subsequent filter primitive within the same <filter> element. If no value is provided, the output will only be available for re-use as the implicit input into the next filter primitive if that filter primitive provides no value for its in attribute.

Seventeen elements are using this attribute: <feBlend>, <feColorMatrix>, <feComponentTransfer>, <feComposite>, <feConvolveMatrix>, <feDiffuseLighting>, <feDisplacementMap>, <feDropShadow>, <feFlood>, <feGaussianBlur>, <feImage>, <feMerge>, <feMorphology>, <feOffset>, <feSpecularLighting>, <feTile>, and <feTurbulence>

<svg viewBox="0 0 220 220" xmlns="http://www.w3.org/2000/svg">
  <filter id="displacementFilter">
    <feTurbulence type="turbulence" baseFrequency="0.05"
        numOctaves="2" result="turbulence"/>
    <feDisplacementMap in2="turbulence" in="SourceGraphic"
        scale="50" xChannelSelector="R" yChannelSelector="G"/>
  </filter>

Usage notes

Value <filter-primitive-reference>
Default value None
Animatable Yes
<filter-primitive-reference>
This value is a <custom-ident> and defines the name for the filter primitive. It is only meaningful within a given <filter> element and thus has only local scope. It is legal for the same <filter-primitive-reference> to appear multiple times within the same <filter> element. When referenced, this value will use the closest preceding filter primitive with the given result.
