stdDeviation
The stdDeviation
attribute defines the standard deviation for the blur operation.
You can use this attribute with the following SVG elements:
Example
html
<svg viewBox="0 0 480 200" xmlns="http://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" style="filter: url(#gaussianBlur1);" />
<circle
cx="100"
cy="100"
r="50"
style="filter: url(#gaussianBlur2); transform: translateX(140px);" />
<circle
cx="100"
cy="100"
r="50"
style="filter: url(#gaussianBlur3); transform: translateX(280px);" />
</svg>

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
stdDeviation
is 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.
