Struct DiffuseLightingFilter 

pub struct DiffuseLightingFilter {
    pub surface_scale: f32,
    pub diffuse_constant: f32,
    pub kernel_unit_length: f32,
    pub light_source: LightSource,
}

Diffuse lighting simulation.

Creates a lighting effect by treating the input’s alpha channel as a height map and calculating diffuse (matte) reflection from a light source.

Fields

surface_scale: f32

Surface scale factor for converting alpha values to heights.

diffuse_constant: f32

Diffuse reflection constant (kd). Controls lighting intensity.

kernel_unit_length: f32

Kernel unit length for gradient calculations in user space.

light_source: LightSource

Configuration of the light source (point, distant, or spot).
