Struct Rec709 

pub struct Rec709;

Rec. ITU-R BT.709-6 transfer function.

Same primaries as sRGB with a different curve, using a slope of 4.5 and an effective gamma of approximately 2.222. Used for HD broadcast. Visually close to sRGB but not interchangeable in precision workflows.

Implementations

impl Rec709

pub const ALPHA: f32 = 1.09929682680944

Gain applied in the power-law segment.

pub const POWER: f32 = 0.45

Encoding power exponent.

pub const LINEAR_SLOPE: f32 = 4.5

Slope of the linear toe.

pub const LINEAR_THRESHOLD: f32 = 0.018053968510807

Linear light value at which the curve transitions to the power-law segment.

pub const ENCODED_THRESHOLD: f32 = 0.081242858298635

Encoded signal value at which the curve transitions to the power-law segment.

Trait Implementations

impl Clone for Rec709

fn clone(&self) -> Rec709

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Rec709

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

Formats the value using the given formatter.

impl<F: Float> Decode<F> for Rec709

fn decode(x: F) -> F

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

impl Default for Rec709

fn default() -> Rec709

Returns the “default value” for a type.

impl<F: Float> Encode<F> for Rec709

fn encode(x: F) -> F

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

impl PartialEq for Rec709

fn eq(&self, other: &Rec709) -> 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.
