Enum TransferFunction 

pub enum TransferFunction {
    Bt709,
    Pq,
    Hlg,
    Gamma22,

}

Video transfer function (EOTF / OETF).

Variants

Bt709

ITU-R BT.709 / BT.1886 (standard SDR).

Pq

SMPTE ST 2084 (Perceptual Quantizer, used by HDR10 and Dolby Vision).

Hlg

Gamma22

Gamma 2.2 (legacy / JPEG / sRGB approximation).

Linear

Linear light (no gamma).

Unspecified

Unspecified / unknown.

Implementations

impl TransferFunction

pub fn h273_code(self) -> u8

Returns the ITU-T H.273 / ISO/IEC 23091-2 transfer characteristics code.

pub fn is_hdr(self) -> bool

Returns true if this is an HDR transfer function (PQ or HLG).

pub fn is_wide_gamut(self) -> bool

Returns true if this transfer function uses a wide colour gamut (BT.2020).

Trait Implementations

impl Clone for TransferFunction

fn clone(&self) -> TransferFunction

Returns a duplicate 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<'de> Deserialize<'de> for TransferFunction

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for TransferFunction

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

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 Serialize for TransferFunction

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for TransferFunction

impl Eq for TransferFunction

impl StructuralPartialEq for TransferFunction
