divisor
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since January 2020.
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%;
}
html
<svg viewBox="0 0 420 200" xmlns="https://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)" />
</svg>
Usage notes
| Value | <number> |
