scale - SVG: Scalable Vector Graphics 编辑

The scale attribute defines the displacement scale factor to be used on a <feDisplacementMap> filter primitive. The amount is expressed in the coordinate system established by the primitiveUnits attribute on the <filter> element.

Only one element is using this attribute: <feDisplacementMap>

html, body, svg {
  height: 100%;
}

<svg viewBox="0 0 480 220" xmlns="http://www.w3.org/2000/svg">
  <filter id="displacementFilter" x="-20%" y="-20%" width="140%" height="140%">
    <feTurbulence type="turbulence" baseFrequency="0.05" numOctaves="2" result="turbulence"/>
    <feDisplacementMap in2="turbulence" in="SourceGraphic" scale="5"/>
  </filter>
  <filter id="displacementFilter2" x="-20%" y="-20%" width="140%" height="140%">
    <feTurbulence type="turbulence" baseFrequency="0.05" numOctaves="2" result="turbulence"/>
    <feDisplacementMap in2="turbulence" in="SourceGraphic" scale="50"/>
  </filter>

  <circle cx="100" cy="100" r="80" style="filter: url(#displacementFilter);""/>
  <circle cx="100" cy="100" r="80" style="filter: url(#displacementFilter2); transform: translateX(240px);""/>
