[−][src]Enum scarlet::illuminants::Illuminant
A listing of the supported CIE standard illuminants, standards that describe a particular set of lighting conditions. The most common ones for computers are D50 and D65, differing kinds of daylight. Other ones may be added as time goes on, but they won't be removed and backwards compatibility won't break without warning.
Variants
The CIE D50 standard illuminant. See this page for more information. This has a rough color temperature of 5000 K, so it looks the reddest out of all these standard illuminants, matching "horizon light" in eastern North America. Scarlet uses D50 for internal conversions, as many color spaces use it to define their viewing environment.
The CIE D55 illuminant, slightly less red than D50. This is rather uncommon as a choice for most work, but is still fairly widely used.
The CIE D65 illuminant, representing average noon daylight in eastern North America. This is the recommended official standard for "representative daylight" according to the CIE. The most common RGB standard, on which you're probably reading this, assumes D65 as viewing conditions.
The CIE D75 illuminant. Rarer than the others, this is nontheless included for the occasional place where it might be used.
Represents a light of any given hue, as an array [X, Y, Z]
in CIE 1931 space. This does not
allow one to replicate any illuminant, but it does allow for custom illuminants and the
ability to chromatically adapt to unique lighting conditions, like dark shade or colored
light.
Methods
impl Illuminant
[src]
pub fn white_point(&self) -> [f64; 3]
[src]
Gets the XYZ coordinates of the white point value of the illuminant, normalized so Y = 1.
Example
let wp = Illuminant::D65.white_point(); // [0.95047, 1.00000, 1.08884] assert!((wp[0] - 0.95047).abs() <= 1e-10); assert!((wp[1] - 1.00000).abs() <= 1e-10); assert!((wp[2] - 1.08884).abs() <= 1e-10);
