intercept

The intercept attribute defines the intercept of the linear function of color component transfers when the {{SVGAttr("type")}} attribute is set to linear.

The linear function is defined as slope * color + intercept, where color is the color value, the intercept provides a base value for the result, and the slope is a scaling factor.

The intercept attribute is supported by children of the {{SVGElement("feComponentTransfer")}} filter primitive and is used with the following SVG component transfer function elements when type="linear" is set:

{{SVGElement("feFuncA")}}
{{SVGElement("feFuncB")}}
{{SVGElement("feFuncG")}}
{{SVGElement("feFuncR")}}

<table class="properties"> <tbody> <tr> <th scope="row">Value</th> <td>{{cssxref("number")}}</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>

<number>
- : This value indicates the intercept of the linear component transfer functions.
