Struct PatternSpace 

pub struct PatternSpace {
    pub base: Option<Box<ColorSpace>>,
}

A Pattern colorspace: a marker with, for uncoloured patterns, the space its scn operands live in.

The base is genuinely optional: a [/Pattern <unloadable>] array loads successfully as a one-component pattern space with no base, which is the uncoloured-pattern case.

Fields

base: Option<Box<ColorSpace>>

The underlying space for an uncoloured pattern’s colour operands.

Implementations

impl PatternSpace

pub fn n_components(&self) -> usize

The component count: one for a bare /Pattern, one more than the base’s otherwise.

pub fn to_rgb(&self, comps: &[f32]) -> Option<Rgb>

Resolve an uncoloured pattern’s colour from its operands.

The base sees the whole operand array regardless of its own component count, matching GetPatternRGB.
