Struct freya_engine::prelude::CubicResampler

#[repr(C)]
pub struct CubicResampler {
    pub b: f32,
    pub c: f32,
}

Specify b and c (each between 0…1) to create a shader that applies the corresponding cubic reconstruction filter to the image.

Example values: b = 1/3, c = 1/3 “Mitchell” filter b = 0, c = 1/2 “Catmull-Rom” filter

Implementations

impl CubicResampler

pub fn mitchell() -> CubicResampler

pub fn catmull_rom() -> CubicResampler

Trait Implementations

impl Clone for CubicResampler

fn clone(&self) -> CubicResampler

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CubicResampler

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

Formats the value using the given formatter.

impl From<CubicResampler> for SamplingOptions

fn from(cubic: CubicResampler) -> SamplingOptions

Converts to this type from the input type.

impl PartialEq for CubicResampler

fn eq(&self, other: &CubicResampler) -> 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.
