This feature is well established and works across many devices and browser versions. It’s been available across browsers since 2018年10月.
* Some parts of this feature may have varying levels of support.
<feGaussianBlur> は SVG のフィルタープリミティブで、ベルカーブを定義する stdDeviation で指定された量だけ入力画像をぼかします。
他のフィルタープリミティブと同様に、既定では色成分を linearRGB 色空間で処理します。 color-interpolation-filters を使用すると、代わりに sRGB を使用することができます。
