Struct ChromaSubsampling 

pub struct ChromaSubsampling {
    pub horizontal: bool,
    pub vertical: bool,
}

Chroma subsampling configuration for AV1/AVIF.

(false, false) = 4:4:4 (no subsampling). (true, true) = 4:2:0 (both axes subsampled). (true, false) = 4:2:2 (horizontal only).

Fields

horizontal: bool

Whether the horizontal (X) axis is subsampled.

vertical: bool

Whether the vertical (Y) axis is subsampled.

Implementations

impl ChromaSubsampling

pub const NONE: Self

4:4:4 — no chroma subsampling.

pub const YUV420: Self

4:2:0 — both axes subsampled.

pub const YUV422: Self

4:2:2 — horizontal subsampling only.

Trait Implementations

impl Clone for ChromaSubsampling

fn clone(&self) -> ChromaSubsampling

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChromaSubsampling

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

Formats the value using the given formatter.

impl From<(bool, bool)> for ChromaSubsampling

fn from((h, v): (bool, bool)) -> Self

Converts to this type from the input type.

impl From<ChromaSubsampling> for (bool, bool)

fn from(cs: ChromaSubsampling) -> Self

Converts to this type from the input type.

impl PartialEq for ChromaSubsampling

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