stdDeviation
The stdDeviation attribute defines the standard deviation for the blur operation.
You can use this attribute with the following SVG elements:
Example
html,
body,
svg {
height: 100%;
}
html
<svg viewBox="0 0 480 200" xmlns="https://www.w3.org/2000/svg">
<filter id="gaussianBlur1">
<feGaussianBlur stdDeviation="1" />
</filter>
<filter id="gaussianBlur2">
<feGaussianBlur stdDeviation="5" />
</filter>
<filter id="gaussianBlur3" x="-30%" y="-30%" width="160%" height="160%">
<feGaussianBlur stdDeviation="10" />
</filter>
<circle cx="100" cy="100" r="50" filter="url(#gaussianBlur1)" />
<circle cx="240" cy="100" r="50" filter="url(#gaussianBlur2)" />
<circle cx="380" cy="100" r="50" filter="url(#gaussianBlur3)" />
</svg>
Usage notes
| Value |
<number-optional-number>
|
|---|---|
| Default value | 0 |
| Animatable | Yes |
<number-optional-number>-
If two numbers are provided, the first number represents a standard deviation value along the x-axis. The second value represents a standard deviation along the y-axis. If one number is provided, then that value is used for both X and Y.
A negative value is forbidden. A value of zero disables the effect of the given filter primitive (i.e., the result is the filter input image). If
stdDeviationis 0 in only one of X or Y, then the effect is that the blur is only applied in the direction that has a non-zero value.
