svg attribute

divisor

View on MDN ↗

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

html,
body,
svg {
  height: 100%;
}
<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
    href="mdn_logo_only_color.png"
    width="200"
    height="200"
    filter="url(#convolveMatrix1)" />
  <image
    x="220"
    href="mdn_logo_only_color.png"
    width="200"
    height="200"
    filter="url(#convolveMatrix2)" />
