Trait PixelFormat

pub trait PixelFormat: Send + Sync {
    type InputPixel: Send + Sync + Copy;
    type OutputPixel: Default + Send + Sync + Copy;
    type Accumulator: Send + Sync + Copy;

    // Required methods
    fn new() -> Self::Accumulator;
    fn add(
        &self,
        acc: &mut Self::Accumulator,
        inp: Self::InputPixel,
        coeff: f32,
    );
    fn add_acc(acc: &mut Self::Accumulator, inp: Self::Accumulator, coeff: f32);
    fn into_pixel(&self, acc: Self::Accumulator) -> Self::OutputPixel;
}

Use Pixel presets to specify pixel format.

The trait represents a temporary object that adds pixels together.

Required Associated Types

type InputPixel: Send + Sync + Copy

Pixel type in the source image

type OutputPixel: Default + Send + Sync + Copy

Pixel type in the destination image (usually the same as Input)

type Accumulator: Send + Sync + Copy

Temporary struct for the pixel in floating-point

Required Methods

fn new() -> Self::Accumulator

Create new floating-point pixel

fn add(&self, acc: &mut Self::Accumulator, inp: Self::InputPixel, coeff: f32)

Add new pixel with a given weight (first axis)

fn add_acc(acc: &mut Self::Accumulator, inp: Self::Accumulator, coeff: f32)

Add bunch of accumulated pixels with a weight (second axis)

fn into_pixel(&self, acc: Self::Accumulator) -> Self::OutputPixel

Finalize, convert to output pixel format

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
