Struct Flatten 

pub struct Flatten { /* private fields */ }

Composite an image onto an opaque background, discarding alpha.

Implementations

impl Flatten

pub const fn onto(red: u8, green: u8, blue: u8) -> Flatten

Flatten onto an 8-bit RGB background.

pub const fn black() -> Flatten

Flatten onto black, the usual default.

pub const fn background(&self) -> [u8; 3]

The background colour.

Trait Implementations

impl Clone for Flatten

fn clone(&self) -> Flatten

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Flatten

impl Debug for Flatten

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

Formats the value using the given formatter.

impl Eq for Flatten

impl Hash for Flatten

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

where __H: Hasher,

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 Op for Flatten

fn rescaled(&self) -> Option<Arc<dyn Op>>

Pointwise: every output pixel depends on the one input pixel beneath it, with no length or coordinate anywhere, so resolution is irrelevant to what this op means, and there is no bound state to discard.

fn name(&self) -> &'static str

A short, stable name for this op, used in diagnostics.

fn output_descriptor( &self, inputs: &[ImageDescriptor], ) -> Result<ImageDescriptor, PixelsError>

Compute the output shape from the input shapes.

fn input_regions( &self, output: Region, _inputs: &[ImageDescriptor], ) -> Result<Vec<Region>, PixelsError>

The input regions needed to produce output.

fn compute( &self, inputs: &[Tile<'_>], output: &mut TileMut<'_>, ) -> Result<(), PixelsError>

Fill output from inputs — the kernel entry point.

fn arity(&self) -> usize

The number of inputs this op consumes.

fn access_pattern(&self) -> AccessPattern

How this op reads its inputs; drives tile negotiation (ADR-0003).

impl PartialEq for Flatten

fn eq(&self, other: &Flatten) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
