Struct ChromaKeyOptions

Source

pub struct ChromaKeyOptions {
    pub method: ChromaKeyMethod,
    pub threshold: f32,
    pub smoothing: f32,
}

Expand description

Construction-time options for either chroma-key backend.

Fields§

§method: ChromaKeyMethod

Color selection used as the transparent key.

§threshold: f32

How far (as a fraction of the maximum possible RGB distance, so 0.0..=1.0 is the meaningful range) a pixel may differ from the key color before it counts as foreground rather than background.

§smoothing: f32

Width of the linear feather band straddling threshold, in the same 0.0..=1.0 units — this is what keeps a key edge from aliasing into a hard, jagged cutout. 0.0 (or negative) is a hard step with no feathering at all.
