Struct PatternValue 

pub struct PatternValue {
    pub name: Name,
    pub components: SmallVec<[f32; 4]>,
    pub loaded: Option<Arc<Pattern>>,
}

A pattern colour: which pattern, and the components an uncoloured one paints with.

Fields

name: Name

The pattern’s name in the /Pattern resource dictionary.

components: SmallVec<[f32; 4]>

The colour operands, capped at sixteen. Meaningless for a coloured (/PaintType 1) pattern, which supplies its own.

loaded: Option<Arc<Pattern>>

The pattern the name resolved to, when it resolved to one.

Loading it here rather than at paint time is what lets the renderer stay free of the resolver: a tiling cell’s page objects and a shading pattern’s ramp are both already in hand by the time an object carrying this colour reaches the walk. None only where scn named a pattern the resources do not define, which is a no-op operator.
