Fields

crc32: Option<Crc32>

Optional CRC-32 element for integrity checking.

void: Option<Void>

void element, useful for reserving space during writing.

matrix_coefficients: MatrixCoefficients

The Matrix Coefficients of the video used to derive luma and chroma values from red, green, and blue color primaries. For clarity, the value and meanings for MatrixCoefficients are adopted from Table 4 of ISO/IEC 23001-8:2016 or ITU-T H.273.

bits_per_channel: BitsPerChannel

Number of decoded bits per channel. A value of 0 indicates that the BitsPerChannel is unspecified.

chroma_subsampling_horz: Option<ChromaSubsamplingHorz>

The amount of pixels to remove in the Cr and Cb channels for every pixel not removed horizontally. Example: For video with 4:2:0 chroma subsampling, the ChromaSubsamplingHorz SHOULD be set to 1.

chroma_subsampling_vert: Option<ChromaSubsamplingVert>

The amount of pixels to remove in the Cr and Cb channels for every pixel not removed vertically. Example: For video with 4:2:0 chroma subsampling, the ChromaSubsamplingVert SHOULD be set to 1.

cb_subsampling_horz: Option<CbSubsamplingHorz>

The amount of pixels to remove in the Cb channel for every pixel not removed horizontally. This is additive with ChromaSubsamplingHorz. Example: For video with 4:2:1 chroma subsampling, the ChromaSubsamplingHorz SHOULD be set to 1 and CbSubsamplingHorz SHOULD be set to 1.

cb_subsampling_vert: Option<CbSubsamplingVert>

The amount of pixels to remove in the Cb channel for every pixel not removed vertically. This is additive with ChromaSubsamplingVert.

chroma_siting_horz: ChromaSitingHorz

How chroma is subsampled horizontally.

• 0 - unspecified,
• 1 - left collocated,
• 2 - half

chroma_siting_vert: ChromaSitingVert

How chroma is subsampled vertically.

• 0 - unspecified,
• 1 - top collocated,
• 2 - half

range: Range

Clipping of the color ranges.

• 0 - unspecified,
• 1 - broadcast range,
• 2 - full range (no clipping),
• 3 - defined by MatrixCoefficients / TransferCharacteristics

transfer_characteristics: TransferCharacteristics

The transfer characteristics of the video. For clarity, the value and meanings for TransferCharacteristics are adopted from Table 3 of ISO/IEC 23091-4 or ITU-T H.273.

Trait Implementations

impl Clone for Colour

fn clone(&self) -> Colour

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Colour

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

Formats the value using the given formatter.

impl Default for Colour

fn default() -> Colour

Returns the “default value” for a type.

impl Element for Colour

const ID: VInt64

EBML ID of the element.

fn decode_body<B: Buf>(buf: &mut B) -> Result<Self>

Decode the body of the element from a buffer.

fn encode_body<B: BufMut>(&self, buf: &mut B) -> Result<()>

Encode the body of the element to a buffer.

const HAS_DEFAULT_VALUE: bool = false

Whether the element has a default value, as per Matroska specification. If true, and the element is missing in a master element, it should be treated as if it were present with the default value. If false, and the element is missing in a master element, it should be treated as an error.

impl PartialEq for Colour

fn eq(&self, other: &Colour) -> 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 StructuralPartialEq for Colour
