Struct ColorContext 

#[non_exhaustive]
pub struct ColorContext {
    pub icc: Option<Arc<[u8]>>,
    pub cicp: Option<Cicp>,
    pub color_authority: ColorAuthority,
}

Color space metadata for pixel data.

Bundles ICC profile bytes and/or CICP parameters into a single shareable context. Carried via Arc on pixel slices and pipeline sources so color metadata travels with pixel data without per-strip cloning overhead.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

icc: Option<Arc<[u8]>>

Raw ICC profile bytes.

cicp: Option<Cicp>

CICP parameters (ITU-T H.273).

color_authority: ColorAuthority

Which field the CMS should treat as authoritative for transforms.

Implementations

impl ColorContext

pub fn from_icc(icc: impl Into<Arc<[u8]>>) -> ColorContext

Create from an ICC profile.

pub fn from_cicp(cicp: Cicp) -> ColorContext

Create from CICP parameters.

pub fn from_icc_and_cicp(icc: impl Into<Arc<[u8]>>, cicp: Cicp) -> ColorContext

Create from both ICC and CICP.

pub fn as_profile_source(&self) -> Option<ColorProfileSource<'_>>

Get a ColorProfileSource reference for CMS integration.

Returns a source based on ColorAuthority: when authority is Cicp, returns CICP if present; when authority is Icc, returns ICC bytes if present. In both cases, falls back to the other field if the authoritative one is absent, and returns None when neither is present.

pub fn transfer_function(&self) -> TransferFunction

Derive transfer function from CICP (or Unknown if no CICP).

pub fn is_srgb(&self) -> bool

True if this describes sRGB (either via CICP or trivially).

Trait Implementations

impl Clone for ColorContext

fn clone(&self) -> ColorContext

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ColorContext

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

Formats the value using the given formatter.

impl PartialEq for ColorContext

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