Struct Color 

pub struct Color {
    pub r: u8,
    pub g: u8,
    pub b: u8,
    pub a: u8,
    pub cmyk: Option<[f32; 4]>,
}

An sRGB 8-bit color with pre-multiplied-independent alpha.

r, g, b, a are all in 0..=255 (linear 8-bit sRGB per channel, straight / un-pre-multiplied alpha).

cmyk is None for sRGB-origin colors. When a color token was declared in CMYK (cmyk(c,m,y,k)), this carries the original [c, m, y, k] percentages (0.0..=100.0) so a future PDF backend can emit native DeviceCMYK; the r/g/b channels then hold the naive device sRGB conversion. The PNG renderer ignores cmyk entirely and paints with r/g/b/a.

Fields

r: u8

g: u8

b: u8

a: u8

cmyk: Option<[f32; 4]>

Original CMYK channels [c, m, y, k] (percentages) when this color was declared in CMYK; None for sRGB-origin colors. Skipped in JSON when absent so existing sRGB scenes serialize byte-identically.

Implementations

impl Color

pub const fn srgb(r: u8, g: u8, b: u8, a: u8) -> Self

Construct an sRGB-origin color (cmyk is None).

pub const fn cmyk(c: f32, m: f32, y: f32, k: f32, r: u8, g: u8, b: u8) -> Self

Construct a CMYK-origin opaque color from the original channels plus the already-converted sRGB triple. c/m/y/k are percentages (0.0..=100.0); the converted r/g/b are supplied by the caller so the deterministic conversion lives in exactly one place (zenith_core::cmyk_to_srgb). Alpha is always 255.

Trait Implementations

impl Clone for Color

fn clone(&self) -> Color

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Color

impl Debug for Color

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

Formats the value using the given formatter.

impl PartialEq for Color

fn eq(&self, other: &Color) -> 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.

impl Serialize for Color

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
