Struct Subsampling 

pub struct Subsampling {
    pub x_ref: u8,
    pub x_samples: u8,
    pub x2_samples: u8,
}

Describes the chroma subsampling system

The struct fields represent the numbers of the typical <x_ref>:<x_samples>:<x2_samples> format

Fields

x_ref: u8

x_samples: u8

x2_samples: u8

Implementations

impl Subsampling

pub const fn new(x_ref: u8, x_samples: u8, x2_samples: u8) -> Self

pub const fn none() -> Self

4:4:4 (no subsampling)

pub const fn is_subsampled(&self) -> bool

pub const fn is_regular(&self) -> bool

Checks if the subsampling format is regular, if a format is irregular it just doesn’t make any sense

pub fn x_grouping(&self) -> u8

Gets the number of x pixels that form a color block

Panics

Panics if the format is not regular

pub fn y_grouping(&self) -> u8

Gets the number of y pixels that form a color block

Panics

Panics if the format is not regular

Trait Implementations

impl Clone for Subsampling

fn clone(&self) -> Subsampling

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Subsampling

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

Formats the value using the given formatter.

impl Default for Subsampling

fn default() -> Self

Returns the “default value” for a type.

impl Display for Subsampling

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

Formats the value using the given formatter.

impl Hash for Subsampling

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Subsampling

fn eq(&self, other: &Subsampling) -> 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 Copy for Subsampling

impl Eq for Subsampling
