Enum ResamplingMethod 

pub enum ResamplingMethod {
    NearestNeighbor,
    Bilinear,
    Bicubic,
    Lanczos {
        a: u32,
    },
}

Resampling method.

Variants

NearestNeighbor

Nearest neighbor (fast, blocky).

Bilinear

Bilinear interpolation (smooth, fast).

Bicubic

Bicubic interpolation (highest quality, slower).

Lanczos

Lanczos resampling with window radius a (typical values: 2 or 3).

Evaluates L(x) = sinc(x) * sinc(x/a) for |x| < a, else 0. The 2D kernel is the outer product of two 1D Lanczos kernels. Results are normalized by dividing by the total weight sum.

Valid range for a: 1..=8.

Fields

a: u32

Window radius (half-width). Valid range: 1..=8.

Implementations

impl ResamplingMethod

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

Get the shader entry point name for this resampling method.

Trait Implementations

impl Clone for ResamplingMethod

fn clone(&self) -> ResamplingMethod

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ResamplingMethod

impl Debug for ResamplingMethod

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

Formats the value using the given formatter.

impl Eq for ResamplingMethod

impl PartialEq for ResamplingMethod

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