pub enum CicpColorPrimaries {
    SRgb = 1,
    Unspecified = 2,
    RgbM = 4,
    RgbB = 5,

}

Defines the exact color of red, green, blue primary colors.

Each set defines the CIE 1931 XYZ (2°) color space coordinates of the primary colors and an illuminant/whitepoint under which those colors are viewed.

Refer to Rec H.273 Table 2.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

SRgb = 1

ITU-R BT.709-6

Unspecified = 2

Explicitly, the color space is not determined.

RgbM = 4

ITU-R BT.470-6 System M

RgbB = 5

ITU-R BT.470-6 System B, G

Bt601 = 6

SMPTE 170M functionally equivalent to 7

Rgb240m = 7

SMPTE 240M functionally equivalent to 6

GenericFilm = 8

Generic film (colour filters using Illuminant C)

Rgb2020 = 9

Rec. ITU-R BT.2020-2 Rec. ITU-R BT.2100-2

Xyz = 10

SMPTE ST 428-1

(CIE 1931 XYZ as in ISO/CIE 11664-1)

SmpteRp431 = 11

SMPTE RP 431-2 (aka. DCI P3)

SmpteRp432 = 12

SMPTE EG 432-1, DCI P3 variant with the D65 whitepoint (matching sRGB and BT.2020)

Industry22 = 22

Corresponds to value 22 but

No corresponding industry specification identified

But moxcms identifies it as EBU Tech 3213-E: https://tech.ebu.ch/docs/tech/tech3213.pdf

However, there are some differences in the second digit of red’s CIE 1931 and the precision is only 2 digits whereas CICP names three; so unsure if this is fully accurate as the actual source material.

Trait Implementations

impl Clone for CicpColorPrimaries

fn clone(&self) -> CicpColorPrimaries

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CicpColorPrimaries

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for CicpColorPrimaries

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for CicpColorPrimaries

fn eq(&self, other: &CicpColorPrimaries) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
