Struct Scaler

pub struct Scaler { /* private fields */ }

Represents base scaling structure

Implementations

impl Scaler

pub fn new(filter: ResamplingFunction) -> Self

Creates new Scaler instance with corresponding filter

impl Scaler

pub fn resize_plane_f32( &self, new_size: ImageSize, store: ImageStore<'_, f32, 1>, ) -> ImageStore<'_, f32, 1>

Performs rescaling for f32 plane

impl Scaler

pub fn resize_plane( &self, new_size: ImageSize, store: ImageStore<'_, u8, 1>, ) -> ImageStore<'_, u8, 1>

Performs rescaling for u8 plane

Trait Implementations

impl Clone for Scaler

fn clone(&self) -> Scaler

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Scaler

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

Formats the value using the given formatter.

impl Scaling for Scaler

fn set_threading_policy(&mut self, threading_policy: ThreadingPolicy)

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

Performs rescaling for RGB, channel order does not matter

fn resize_rgba( &self, new_size: ImageSize, store: ImageStore<'_, u8, 4>, is_alpha_premultiplied: bool, ) -> ImageStore<'_, u8, 4>

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

impl ScalingF32 for Scaler

fn resize_rgb_f32( &self, new_size: ImageSize, store: ImageStore<'_, f32, 3>, ) -> ImageStore<'_, f32, 3>

Performs rescaling for RGB f32, channel order does not matter

fn resize_rgba_f32( &self, new_size: ImageSize, store: ImageStore<'_, f32, 4>, is_alpha_premultiplied: bool, ) -> ImageStore<'_, f32, 4>

Performs rescaling for RGBA f32, alpha expected to be last

impl ScalingU16 for Scaler

fn resize_rgba_u16( &self, new_size: ImageSize, store: ImageStore<'_, u16, 4>, bit_depth: usize, is_alpha_premultiplied: bool, ) -> ImageStore<'_, u16, 4>

Resizes u16 image

Arguments

new_size - New image size store - original image store bit_depth - image bit depth, this is required for u16 image is_alpha_premultiplied - flags is alpha is premultiplied

Panics

Panic if bit depth < 1 or bit depth > 16

fn resize_plane_u16( &self, new_size: ImageSize, store: ImageStore<'_, u16, 1>, bit_depth: usize, ) -> ImageStore<'_, u16, 1>

Performs rescaling for u16 plane

fn resize_rgb_u16( &self, new_size: ImageSize, store: ImageStore<'_, u16, 3>, bit_depth: usize, ) -> ImageStore<'_, u16, 3>

Performs rescaling for RGB, channel order does not matter
