Struct rsvg::filters::lighting::Normal

source · 
pub struct Normal {
    pub factor: Vector2<f64>,
    pub normal: Vector2<i16>,
}
Expand description

2D normal and factor stored separately.

The normal needs to be multiplied by surface_scale * factor / 255 and normalized with 1 as the z component. pub for the purpose of accessing this from benchmarks.
