Struct Matrix3 

pub struct Matrix3<Src: ColorSpace, Dst: ColorSpace> { /* private fields */ }

Q4_28 coefficients that convert Color<Src, Linear> to Color<Dst, Linear>.

Implementations

impl<Src: ColorSpace, Dst: ColorSpace> Matrix3<Src, Dst>

pub const fn from_q428(coefs: [[Q4_28; 3]; 3]) -> Self

Wrap baked Q4_28 coefficients. Target code does not derive them.

pub const fn apply(&self, color: Color<Src, Linear>) -> Color<Dst, Linear>

Apply to a linear source: one i64 accumulate per row, then one shift-round-saturate. There is no inverse or chromatic adaptation.

pub fn apply_f32(&self, color: ColorF32<Src, Linear>) -> ColorF32<Dst, Linear>

Apply with f32 mul/add of Q4.28 coefficients decoded as coef as f32 / 2^28. Saturates each channel to 0.0..=1.0.

Additive: does not change Self::apply. Error versus W7 goldens is at most crate::F32_MAX_ERR_LSB.
