bias

The bias attribute shifts the range of the filter. After applying the {{SVGAttr("kernelMatrix")}} of the {{SVGElement("feConvolveMatrix")}} element to the input image to yield a number and applied the {{SVGAttr("divisor")}} attribute, the bias attribute is added to each component. This allows representation of values that would otherwise be clamped to 0 or 1.

You can use this attribute with the following SVG elements:

• {{SVGElement("feConvolveMatrix")}}

Usage notes

<table class="properties"> <tbody> <tr> <th scope="row">Value</th> <td> <a href="/en-US/docs/Web/SVG/Guides/Content_type#number">&#x3C;number></a> </td> </tr> <tr> <th scope="row">Default value</th> <td><code>0</code></td> </tr> <tr> <th scope="row">Animatable</th> <td>Yes</td> </tr> </tbody> </table>

One application of bias is when it is desirable to have 0.5 gray value be the zero response of the filter.
