divisor

The divisor attribute specifies the value by which the resulting number of applying the kernelMatrix of a <feConvolveMatrix> element to the input image color value is divided to yield the destination color value.

A divisor that is the sum of all the matrix values tends to have an evening effect on the overall color intensity of the result.

You can use this attribute with the following SVG elements:

Example

<svg viewBox="0 0 420 200" xmlns="http://www.w3.org/2000/svg">
  <filter id="convolveMatrix1" x="0" y="0" width="100%" height="100%">
    <feConvolveMatrix kernelMatrix="1 2 0 0 0 0 0 0 -1" divisor="1" />
  </filter>
  <filter id="convolveMatrix2" x="0" y="0" width="100%" height="100%">
    <feConvolveMatrix kernelMatrix="1 2 0 0 0 0 0 0 -1" divisor="8" />
  </filter>

  <image
    xlink:href="mdn_logo_only_color.png"
    width="200"
    height="200"
    style="filter:url(#convolveMatrix1);" />
  <image
    xlink:href="mdn_logo_only_color.png"
    width="200"
    height="200"
    style="filter:url(#convolveMatrix2); transform:translateX(220px);" />
</svg>

Usage notes

Value <number>
Default value Sum of all values in kernelMatrix or 1 if sum is 0
Animatable Yes
<number>

This value defines the divisor. If the specified divisor is 0 then the default value will be used instead.
