Enum ScaleFilter 

pub enum ScaleFilter {
    Nearest,
    Bilinear,
    Bicubic,
    Area,
}

Interpolation filter used when scaling.

Variants

Nearest

Nearest-neighbor: fast, blocky.

Bilinear

Bilinear: smooth, slight blur.

Bicubic

Bicubic (Keys, a = -0.5): sharper than bilinear.

Area

Area averaging: best for significant downscale (anti-aliasing).

Implementations

impl ScaleFilter

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

Human-readable label.

Trait Implementations

impl Clone for ScaleFilter

fn clone(&self) -> ScaleFilter

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ScaleFilter

impl Debug for ScaleFilter

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

Formats the value using the given formatter.

impl Eq for ScaleFilter

impl Hash for ScaleFilter

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ScaleFilter

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