Struct LinearScaler

pub struct LinearScaler { /* private fields */ }

Converts image to linear f32 components scales it and convert back. This is more precise and slower than scaling in linear u8 If you want just scale faster use LinearApproxScaler

Implementations

impl LinearScaler

pub fn new(filter: ResamplingFunction) -> Self

Creates new instance with sRGB transfer function

pub fn new_with_transfer( filter: ResamplingFunction, transfer_function: TransferFunction, ) -> Self

Creates new instance with requested transfer function

Trait Implementations

impl Clone for LinearScaler

fn clone(&self) -> LinearScaler

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LinearScaler

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

Formats the value using the given formatter.

impl Scaling for LinearScaler

fn set_threading_policy(&mut self, threading_policy: ThreadingPolicy)

fn resize_rgb( &self, new_size: ImageSize, store: ImageStore<'_, u8, 3>, ) -> Result<ImageStore<'_, u8, 3>, PicScaleError>

Performs rescaling for RGB, channel order does not matter

fn resize_rgba<'a>( &'a self, new_size: ImageSize, store: ImageStore<'a, u8, 4>, premultiply_alpha: bool, ) -> Result<ImageStore<'a, u8, 4>, PicScaleError>

Performs rescaling for RGBA, for pre-multiplying alpha, converting to LUV or LAB alpha must be last channel
