impl TransferFunction

pub fn name(&self) -> &'static str

pub fn process(&self, pixels: &mut [f32])

Apply the OETF (linear → log) for the selected transfer function.

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 Copy for TransferFunction

impl Debug for TransferFunction

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

Formats the value using the given formatter.

impl Eq for TransferFunction

impl From<TransferFunction> for Transfer

fn from(tf: TransferFunction) -> Self

Converts to this type from the input 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.
