donner::svg::components::AnimationValueContext

struct donner::svg::components::AnimationValueContext

Context required to resolve relative units and currentColor for an animated value.

Class Members
bool	angleValue = false	Marker orientation operands use SVG angle units.
RGBA	currentColor = css::RGBA::RGB(0, 0, 0)	Resolved currentColor.
Extent	extent = Lengthd::Extent::Mixed	Percentage reference axis.
FontMetrics	fontMetrics	Font and viewport unit metrics.
bool	integerValue = false	Round interpolated numeric values to the nearest integer.
bool	lengthValuesAreOffsets = false	Sample operands are displacements, not positions.
bool	linearRgb = false	Interpolate colors in linear-light RGB when requested. Map mixed-unit filter lengths to user-space pixels while keeping additive offsets origin-free.
bool	mappedLengths = false
size_t	maximumNumbers = 0
bool	numberPair = false	Repeat one coordinate for number-optional-number values.
bool	percentageNumbers	Percentages represent fractions of one, not viewport lengths.
double	percentageOrigin = 0	Origin added only to percentage positions.
bool	referenceValue = false	References are discrete and non-additive. Zero accepts general values; otherwise only this many dimensionless operands are allowed.
double	unitlessOrigin = 0	Origin added only to unitless positions.
double	unitlessScale = 1	User units represented by one unitless coordinate.
Box2d	viewBox {{0, 0}, {300, 150}}	Current SVG viewport in user units.
