Enum skia_safe::yuva_pixmaps::yuva_pixmap_info::Subsampling

#[repr(i32)]
pub enum Subsampling {
    Unknown,
    S444,
    S422,
    S420,
    S440,
    S411,
    S410,
}

UV subsampling is also specified in the enum value names using J:a:b notation (e.g. 4:2:0 is 1/2 horizontal and 1/2 vertical resolution for U and V). If alpha is present it is not sub- sampled. Note that Subsampling values other than k444 are only valid with PlaneConfig values that have U and V in different planes than Y (and A, if present).

Trait Implementations

impl Clone for Subsampling

fn clone(&self) -> Subsampling

Returns a copy 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 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<Subsampling> for Subsampling

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

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
