Struct NoTransfer 

pub struct NoTransfer;

Identity transfer function: no conversion.

Used when pixel data is already in the desired space, or when resizing should happen in the encoded domain (gamma-space resize). All batch methods are trivial copies/scales.

Trait Implementations

impl Clone for NoTransfer

fn clone(&self) -> NoTransfer

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NoTransfer

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

Formats the value using the given formatter.

impl Default for NoTransfer

fn default() -> NoTransfer

Returns the “default value” for a type.

impl TransferCurve for NoTransfer

type Luts = ()

Cached state (LUTs, etc.). Built once by build_luts(), passed to batch methods.

fn to_linear(&self, v: f32) -> f32

Encode a linear-light value to this TF’s encoded space. Both input and output are in [0, 1] for SDR TFs.

fn from_linear(&self, v: f32) -> f32

Decode a value from this TF’s encoded space to linear light.

fn is_identity(&self) -> bool

Whether this TF is the identity (no conversion needed).

fn build_luts(&self) -> Self::Luts

Build or retrieve cached LUTs.

fn u8_to_linear_f32( &self, src: &[u8], dst: &mut [f32], _luts: &(), _channels: usize, _has_alpha: bool, premul: bool, )

Convert a row of u8 encoded pixels to premultiplied linear f32.

fn linear_f32_to_u8( &self, src: &[f32], dst: &mut [u8], _luts: &(), _channels: usize, _has_alpha: bool, unpremul: bool, )

Convert a row of premultiplied linear f32 to u8 encoded pixels.

fn u16_to_linear_f32( &self, src: &[u16], dst: &mut [f32], _luts: &(), _channels: usize, _has_alpha: bool, premul: bool, )

Convert a row of u16 encoded pixels to premultiplied linear f32.

fn linear_f32_to_u16( &self, src: &[f32], dst: &mut [u16], _luts: &(), _channels: usize, _has_alpha: bool, unpremul: bool, )

Convert premultiplied linear f32 to u16 encoded pixels.

fn u8_to_linear_i12(&self, src: &[u8], dst: &mut [i16], _luts: &())

Convert a row of u8 encoded pixels to linear i12 (0-4095). All channels converted; no premul/unpremul (I16Work doesn’t support premul).

fn linear_i12_to_u8(&self, src: &[i16], dst: &mut [u8], _luts: &())

Convert a row of linear i12 to u8 encoded pixels.

fn f32_to_linear_inplace( &self, row: &mut [f32], _channels: usize, _has_alpha: bool, premul: bool, )

Convert f32 encoded values to premultiplied linear f32 in-place.

fn linear_to_f32_inplace( &self, row: &mut [f32], _channels: usize, _has_alpha: bool, unpremul: bool, )

Convert premultiplied linear f32 to f32 encoded in-place. Does NOT clamp — output can have values outside [0, 1] for wide gamut.
