Trait resize::px::PixelFormat[−][src]

pub trait PixelFormat {
    type InputPixel: Copy;
    type OutputPixel;
    type Accumulator: Copy;
    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.
