{{SVGRef}}

The **`scale`** attribute defines the displacement scale factor to be used on a {{SVGElement("feDisplacementMap")}} filter primitive. The amount is expressed in the coordinate system established by the {{SVGAttr("primitiveUnits")}} attribute on the {{SVGElement("filter")}} element.

You can use this attribute with the following SVG elements:

*   {{SVGElement("feDisplacementMap")}}

## Example

```css hidden
html, body, svg {
  height: 100%;
}
```

```html
<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);""/>
</svg>
```

## Usage notes

<table class="properties">
  <tbody>
    <tr>

*   `<number>`
    *   : This value defines the scale factor for the displacement.

        When the value of this attribute is `0`, this operation has no effect on the source image.
