Meziantou.FrameworkDiffuseLightingPrimitive Class
A primitive that lights the surface whose height is the alpha of its input, as a matte surface: feDiffuseLighting of SVG.
public sealed class DiffuseLightingPrimitive : FilterPrimitiveRemarks
Each pixel of the result is opaque, of the color kd (N.L) C: kd the DiffuseLightingPrimitive.DiffuseConstant, N the normal of the surface (from the alpha of the input, scaled by DiffuseLightingPrimitive.SurfaceScale), L the unit vector toward the light, and C the color of the light in the colors of the primitive, each component clamped to the range from 0 to 1.
