fl::FluxScalar Class Reference

Detailed Description

A linear flux scalar in s16.16.

Deliberately a single scalar for every channel rather than a per-channel array: a chromaticity-changing rescale cannot be expressed through this type at all, which is how C4's "chromaticity preserved by construction" is enforced rather than merely tested.

Public Member Functions
FluxScalar	composedWith (FluxScalar other) const FL_NO_EXCEPT
	Multiplicative composition, commutative: combining brightness and the limiter in either order gives the same scalar, which is all C4 needs.
i32	rawQ16 () const FL_NO_EXCEPT

Static Public Member Functions
static FluxScalar	fromBrightness (u8 brightness) FL_NO_EXCEPT
	setBrightness(b) as the linear flux scalar b/255.
static FluxScalar	fromRawQ16 (i32 raw) FL_NO_EXCEPT
	A limiter fraction already in s16.16, clamped to [0, 1].
static FluxScalar	unity () FL_NO_EXCEPT
	Identity. Drives pass through unchanged.
