seed
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
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:
Example
Example 1
html,
body,
svg {
height: 100%;
}
html
<svg viewBox="0 0 420 200" xmlns="https://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" filter="url(#noise1)" />
<rect x="220" y="0" width="200" height="200" filter="url(#noise2)" />
</svg>
Example 2
html
<svg
width="200"
height="200"
viewBox="0 0 220 220"
xmlns="https://www.w3.org/2000/svg">
<filter id="displacementFilter">
<feTurbulence baseFrequency="0.05" seed="1000" result="turbulence" />
<feDisplacementMap
in2="turbulence"
in="SourceGraphic"
scale="50"
xChannelSelector="R"
yChannelSelector="G" />
</filter>
<circle cx="100" cy="100" r="100" filter="url(#displacementFilter)" />
</svg>
