Enum ChromaFormat 

pub enum ChromaFormat {
    Monochrome,
    Yuv420,
    Yuv422,
    Yuv444,
}

Chroma subsampling mode.

Variants

Monochrome

4:0:0 — monochrome (luma only, no chroma). ChromaArrayType = 0.

Yuv420

4:2:0 — chroma is half width, half height. ChromaArrayType = 1.

Yuv422

4:2:2 — chroma is half width, full height. ChromaArrayType = 2.

Yuv444

4:4:4 — chroma is full width, full height. ChromaArrayType = 3.

Implementations

impl ChromaFormat

pub fn idc(self) -> u32

chroma_format_idc value written in the SPS (HEVC Table 6-1).

pub fn is_monochrome(self) -> bool

True when there is no chroma (4:0:0).

pub fn sub_w(self) -> usize

Horizontal subsampling factor: luma_width / chroma_width. (1 for monochrome, which has no chroma; the value is unused but kept well-defined.)

pub fn sub_h(self) -> usize

Vertical subsampling factor: luma_height / chroma_height.

pub fn chroma_tb_size(self) -> usize

Side length of each chroma transform block for an 8×8 luma CU.

pub fn chroma_tbs_per_cu(self) -> usize

Number of chroma transform blocks stacked vertically per 8×8 luma CU.

Trait Implementations

impl Clone for ChromaFormat

fn clone(&self) -> ChromaFormat

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ChromaFormat

impl Debug for ChromaFormat

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

Formats the value using the given formatter.

impl Eq for ChromaFormat

impl PartialEq for ChromaFormat

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