Struct ColorContext 

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

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

icc: Option<Arc<[u8]>>

Raw ICC profile bytes.

cicp: Option<Cicp>

CICP parameters (ITU-T H.273).

Implementations

impl ColorContext

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

Create from an ICC profile.

pub fn from_cicp(cicp: Cicp) -> Self

Create from CICP parameters.

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

Create from both ICC and CICP.

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

Get a ColorProfileSource reference for CMS integration.

Returns CICP if present (takes precedence per AVIF/HEIF specs), otherwise returns the ICC profile bytes.

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

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.
