seed

The seed attribute represents the starting number for the pseudo random number generator of the <feTurbulence> filter primitive.

You can use this attribute with the following SVG elements:

<feTurbulence>

Example

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

<svg viewBox="0 0 420 200" xmlns="http://www.w3.org/2000/svg">
  <filter id="noise1" x="0" y="0" width="100%" height="100%">
    <feTurbulence baseFrequency="0.025" seed="0" />
  </filter>
  <filter id="noise2" x="0" y="0" width="100%" height="100%">
    <feTurbulence baseFrequency="0.025" seed="100" />
  </filter>

  <rect x="0" y="0" width="200" height="200" style="filter:url(#noise1);" />
  <rect x="0" y="0" width="200" height="200" style="filter:url(#noise2); transform: translateX(220px);" />
</svg>
