Struct D50 

Source 
pub struct D50<O: StandardObserver = Cie1931>(/* private fields */);
Expand description

CIE standard illuminant D50 (~5003 K) under observer O.

D50 is the reference white for the ICC profile connection space (ICC.1:2022) and ProPhoto RGB (ROMM RGB, ISO 22028-2), both defined under Cie1931. Use D50<Cie1964> for surface color evaluation.

Implementations§

Source§

impl D50<Cie1931>

Source

pub const SPD_5NM: &'static [f32; 81]

CIE D50 relative SPD at 5 nm, 380-780 nm (81 bands), normalized to 1.0 at 560 nm. Source: CIE 015:2018 Table T.1.

Source

pub const fn spd<const BANDS: usize, G: WavelengthGrid<BANDS>>() -> [f32; BANDS]

Sample the D50 SPD onto wavelength grid G.

Linearly interpolates the 5 nm source table. Bands outside 380-780 nm are zero. The result is suitable for use in a static initializer.
