Enum MaskMode 

pub enum MaskMode {
    Luminance,
    Alpha,
}

Modo de una máscara (CSS mask-mode). Decide qué canal del píxel-máscara modula el alpha del contenido. Fase 7.1228.

Variants

Luminance

La luminancia del píxel multiplica el alpha (negro = oculto, blanco = visible). Lo usa CSS para máscaras SVG <mask>. Es el default del compositor cuando no hay MaskPlacement (camino estirado, Fase 7.1226).

Alpha

El canal alpha del píxel modula el alpha (transparente = oculto). Es el default CSS para imágenes raster (mask-mode: match-source). Se pinta con Compose::DestIn en vez de la capa de luminancia.
