SVGFEDropShadowElement: stdDeviationY property
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 stdDeviationY read-only property of the SVGFEDropShadowElement interface reflects the (possibly automatically computed) Y component of the stdDeviation attribute of the given <feDropShadow> element.
Value
An SVGAnimatedNumber object.
Examples
Accessing the stdDeviationY value
In this example, we retrieve the vertical standard deviation for the blur operation of the <feDropShadow> by using the stdDeviationY read-only property of the SVGFEDropShadowElement interface.
