Meziantou.FrameworkGaussianBlurPrimitive Class
A primitive that blurs its input: feGaussianBlur of SVG.
public sealed class GaussianBlurPrimitive : FilterPrimitiveRemarks
The blur is the one of BlurFilter, with a standard deviation per axis. What it reads beyond the subregion of its input is given by GaussianBlurPrimitive.EdgeMode, relative to that subregion: transparent (none, the default), the nearest pixel (duplicate), the pixel of the opposite side (wrap), or the mirrored pixel.
