Available on crate feature scale only.

Expand description

Nearest Neighbor image scaling algorithm.

Trait Implementations§

impl ScalingAlgorithm for Nearest

fn scale_opaque<const N: usize>( i: Image<&[u8], N>, w: NonZeroU32, h: NonZeroU32, ) -> Image<Box<[u8]>, N>
where ChannelCount<N>: ToImageView<N>,

Can be used on non opaque too! (Nearest is special like that).

fn scale_transparent<const N: usize>( i: Image<&mut [u8], N>, w: NonZeroU32, h: NonZeroU32, ) -> Image<Box<[u8]>, N>
where ChannelCount<N>: AlphaDiv<N>,

Ya/Rgba scale

Blanket Implementations§

impl<T> Any for T
where T: 'static + ?Sized,

fn type_id(&self) -> TypeId

Gets the TypeId of self. Read more

impl<T> Borrow<T> for T
where T: ?Sized,

fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more

impl<T> BorrowMut<T> for T
where T: ?Sized,

fn borrow_mut(&mut self) -> &mut T

Mutably borrows from an owned value. Read more

impl<T> Downcast<T> for T

fn downcast(&self) -> &T

impl<T> Downcast for T
where T: Any,

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.

impl<T> DowncastSync for T
where T: Any + Send + Sync,

fn into_any_arc(self: Arc<T>) -> Arc<dyn Any + Send + Sync>

Convert Arc<Trait> (where Trait: Downcast) to Arc<Any>. Arc<Any> can then be further downcast into Arc<ConcreteType> where ConcreteType implements Trait.

impl<T> From<T> for T

fn from(t: T) -> T

Returns the argument unchanged.

impl<T, U> Into<U> for T
where U: From<T>,

fn into(self) -> U

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.

impl<T> Join<T, 1, 1, T> for T

fn join(self, with: T) -> [T; 2]

Join a array and an scalar together. For joining two arrays together, see Couple. Read more

impl<T, const O: usize> Join<T, 1, O, [T; O]> for T

fn join(self, with: [T; O]) -> [T; { _ }]

Join a array and an scalar together. For joining two arrays together, see Couple. Read more

impl<T, U> TryFrom<U> for T
where U: Into<T>,

type Error = Infallible

The type returned in the event of a conversion error.

fn try_from(value: U) -> Result<T, <T as TryFrom<U>>::Error>

Performs the conversion.

impl<T, U> TryInto<U> for T
where U: TryFrom<T>,

type Error = <U as TryFrom<T>>::Error

The type returned in the event of a conversion error.

fn try_into(self) -> Result<U, <U as TryFrom<T>>::Error>

Performs the conversion.

impl<T> Upcast<T> for T

fn upcast(&self) -> Option<&T>

impl<T> WasmNotSend for T
where T: Send,

impl<T> WasmNotSendSync for T
where T: WasmNotSend + WasmNotSync,

impl<T> WasmNotSync for T
where T: Sync,
