Trait pix::chan::Channel

pub trait Channel: Copy + Debug + Default + From<f32> + Ord + Add<Output = Self> + Div<Output = Self> + Mul<Output = Self> + Sub<Output = Self> + Sealed {
    const MIN: Self;
    const MID: Self;

    fn to_f32(self) -> f32;
    fn wrapping_add(self, rhs: Self) -> Self;
    fn wrapping_sub(self, rhs: Self) -> Self;

}

Component of a color model, such as red, green, etc.

Existing Channels are Ch8, Ch16 and Ch32.

This trait is sealed, and cannot be implemented outside of this crate.

Required Associated Constants

const MIN: Self

Minimum intensity (zero)

const MID: Self

fn wrapping_add(self, rhs: Self) -> Self

Wrapping addition

fn wrapping_sub(self, rhs: Self) -> Self
