}

Transfer function (tone curve).

Variants

Gamma

Pure gamma curve.

Fields

g: u32

Gamma value, scaled by 1e7 (10_000_000).

inverted: bool

Whether the gamma value is inverted.

If true, g <= 10_000_000.

Bt709 = 1

BT.709 transfer function.

Unknown = 2

Unknown transfer function.

Linear = 8

Linear (gamma of 1).

Srgb = 13

sRGB transfer function.

Pq = 16

Perceptual quantizer (HDR).

Dci = 17

DCI transfer function (gamma of 2.6).

Hlg = 18

Hybrid log-gamma (HDR).

Implementations

impl TransferFunction

pub fn cicp(&self) -> Option<u8>

Returns the CICP value of transfer function, if there is any.

Trait Implementations

impl<Ctx> Bundle<Ctx> for TransferFunction

type Error = Error

fn parse(bitstream: &mut Bitstream<'_>, _ctx: Ctx) -> Result<Self>

Parses a value from the bitstream with the given context.

impl Clone for TransferFunction

fn clone(&self) -> TransferFunction

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TransferFunction

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

Formats the value using the given formatter.

impl Default for TransferFunction

fn default() -> TransferFunction

Returns the “default value” for a type.

impl PartialEq for TransferFunction

fn eq(&self, other: &TransferFunction) -> 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 TryFrom<u32> for TransferFunction

type Error = ()

The type returned in the event of a conversion error.

fn try_from(value: u32) -> Result<Self, Self::Error>

Performs the conversion.
