feGaussianBlur

Overview Table

DOM Interface: SVGElement

Notes

Remarks

The Gaussian blur kernel is an approximation of the normalized convolution

G(x,y) = H(x)I(y),

where

H(x) = exp(-x²/ (2s²)) / sqrt(2* pi*s²)

and

I(y) = exp(-y²/ (2t²)) / sqrt(2* pi*t²)

with ‘s’ being the standard deviation in the x direction and ‘t’ being the standard deviation in the y direction, as specified by the stdDeviationX and stdDeviationY properties.

Members

The SVGFEGaussianBlurElement object has these methods:

setStdDeviation: Sets the standard deviation values used in calculating a Gaussian blur.

The SVGFEGaussianBlurElement object has these properties:

height: Gets or sets the height of an element.
