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]>>) -> 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

👎Deprecated since 0.2.6:

use from_icc() or from_cicp(); roundtrip metadata belongs on ColorOrigin

Create from both ICC and CICP.

Deprecated: Codecs should populate only the authoritative field — use from_icc() or from_cicp(). Roundtrip metadata belongs on ColorOrigin, not ColorContext.

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

Get a ColorProfileSource reference for CMS integration.

Returns ICC if present, otherwise CICP. Returns None when neither is present.

Codecs should populate only the authoritative field on ColorContext at decode time, using ColorAuthority on ColorOrigin to determine which. When only one field is set, this method returns it.

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.
