PhosphorAnimation::detail Namespace Reference

Classes
struct	DecomposedTransform
struct	OkLab

Concepts
concept	PositionalGeometric
	Position-carrying T whose damage region is fully determined by endpoints + overshoot.
concept	SizeGeometric
	Size-only T — caller must supply an anchor for damage rect.
concept	ScalarValue

Functions
qreal	srgbToLinear (qreal c)
qreal	linearToSrgb (qreal c)
QColor	lerpColorLinear (const QColor &from, const QColor &to, qreal t)
OkLab	linearToOkLab (qreal r, qreal g, qreal bv)
void	okLabToLinear (const OkLab &lab, qreal &r, qreal &g, qreal &bv)
QColor	lerpColorOkLab (const QColor &from, const QColor &to, qreal t)
qreal	colorDistance (const QColor &from, const QColor &to)
	L2 norm in linear-RGB space — matches the lerp space so velocity rescale uses a consistent metric.
DecomposedTransform	decomposeTransform (const QTransform &t)
	QR-style decomposition on the 2x2 linear part under Qt's post-multiply row-vector convention: M = R x K x S.
QTransform	recomposeTransform (const DecomposedTransform &d)
bool	isPureTranslate (const QTransform &t)
	True if the 2x2 linear part is identity (only translation present).
QTransform	lerpTransform (const QTransform &from, const QTransform &to, qreal t)
