Struct Negate 

pub struct Negate { /* private fields */ }

Invert colours: each channel becomes 1 - value (sharp’s negate).

Implementations

impl Negate

pub const fn new(alpha: bool) -> Negate

Invert colours, and alpha too if alpha is set. sharp inverts alpha by default.

Trait Implementations

impl Clone for Negate

fn clone(&self) -> Negate

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Negate

impl Debug for Negate

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

Formats the value using the given formatter.

impl Eq for Negate

impl Op for Negate

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

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

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

A copy of this op fit for a graph rebuilt at a reduced input resolution, or None if this op must not be.

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 Negate

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

Equality operator ==.

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

Inequality operator !=.
