Sample position for subsampled chroma

Variants

Unknown

The source video transfer function is not signaled. This crate will assume no transformation needs to be done on this data, but there is a risk of metric calculations being inaccurate.

Vertical

Horizontally co-located with (0, 0) luma sample, vertically positioned in the middle between two luma samples.

Colocated

Co-located with (0, 0) luma sample.

Bilateral

Bilaterally located chroma plane in the diagonal space between luma samples.

Interpolated

Interlaced content with interpolated chroma samples.

Trait Implementations

impl Clone for ChromaSamplePosition

fn clone(&self) -> ChromaSamplePosition

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ChromaSamplePosition

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

Formats the value using the given formatter.

impl Default for ChromaSamplePosition

fn default() -> ChromaSamplePosition

Returns the “default value” for a type.

impl PartialEq<ChromaSamplePosition> for ChromaSamplePosition

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