Struct Pq 

pub struct Pq;

SMPTE ST 2084 Perceptual Quantizer transfer function.

Display-referred HDR where encoded 1.0 represents 10000 cd/m2. Used in HDR10 and as the base layer in Dolby Vision.

Trait Implementations

impl Clone for Pq

fn clone(&self) -> Pq

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Pq

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

Formats the value using the given formatter.

impl<F: Float> Decode<F> for Pq

fn decode(x: F) -> F

Convert an encoded signal value to a linear-light value.

impl Default for Pq

fn default() -> Pq

Returns the “default value” for a type.

impl<F: Float> Encode<F> for Pq

fn encode(x: F) -> F

Convert a linear-light value to an encoded signal value.

impl PartialEq for Pq

fn eq(&self, other: &Pq) -> 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 Pq

impl Eq for Pq

impl StructuralPartialEq for Pq
