Enum ChromaSiting 

#[repr(u8)]
pub enum ChromaSiting {
    Left = 0,
    Center = 1,
    TopLeft = 2,
    Top = 3,
    BottomLeft = 4,

Center = 1

Chroma samples are centered horizontally and vertically.

TopLeft = 2

Chroma samples sit on top-left corner.

Top = 3

Chroma samples are centered horizontally on top edge.

BottomLeft = 4

Chroma samples sit on bottom-left corner.

Bottom = 5

Chroma samples are centered horizontally on bottom edge.

Implementations

impl ChromaSiting

pub fn parse(value: &str) -> Result<ChromaSiting, PixelFlowError>

Parses canonical chroma-siting metadata string.

pub const fn as_str(self) -> &'static str

Returns canonical metadata string.

pub const fn offsets(self) -> (f32, f32)

Returns (x, y) chroma offsets in luma-space coordinates.

Trait Implementations

impl Clone for ChromaSiting

fn clone(&self) -> ChromaSiting

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChromaSiting

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

Formats the value using the given formatter.

impl PartialEq for ChromaSiting

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