Struct ColorMetadata 

pub struct ColorMetadata {
    pub primaries: ColorPrimaries,
    pub transfer: TransferFunction,
    pub matrix: ColorMatrix,
    pub range: ColorRange,
    pub dynamic_range: DynamicRange,
}

Host-independent video color description.

Fields

primaries: ColorPrimaries

RGB chromaticity standard.

transfer: TransferFunction

Nonlinear transfer curve.

matrix: ColorMatrix

YUV-to-RGB coefficient family, or RGB for already converted sources.

range: ColorRange

Encoded component range.

dynamic_range: DynamicRange

SDR or HDR; HDR exactly when transfer is PQ or HLG (Self::is_consistent).

Implementations

impl ColorMetadata

pub const EXPORT: Self

The color every SDR export is tagged with: BT.709 primaries, transfer and matrix, limited range.

The working space is display-referred, so export encodes with the sRGB curve (the exact inverse of SDR input linearization) and tags the result BT.709 like other SDR video.

pub const UNDECLARED: Self = Self::EXPORT

How a source without declared color is decoded: BT.709 limited SDR. The renderer reports it as ColorDiagnostic::MissingMetadataFallback.

pub const fn is_hdr(self) -> bool

Whether the signal is HDR by transfer (PQ or HLG) or classification. Every consumer uses this one rule.

pub const fn is_consistent(self) -> bool

Whether dynamic_range matches transfer (HDR exactly for PQ or HLG). Projects with an inconsistent color are rejected.
