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.
  • in1: Identifies input for the given filter primitive.
  • result: Provides a reference for the output result of a filter.
  • stdDeviationX: Gets a value that indicates the standard deviation in the x-direction, used in calculating a Gaussian blur.
  • stdDeviationY: Gets a value that indicates the standard deviation in the y-direction, used in calculating a Gaussian blur.
  • width: Defines the width of an element.
  • x: Gets or sets the x-coordinate value.
