RescaleArc

Changes radius of an arc and translates its center in relation to a reference point.

Syntax

void avl::RescaleArc
(
	const avl::Arc2D& inArc,
	atl::Optional<const avl::Point2D&> inReferencePoint,
	float inScale,
	bool inInverse,
	avl::Arc2D& outArc
)

void RescaleArc
(
	Arc2D inArc,
	Point2D? inReferencePoint,
	float inScale,
	bool inInverse,
	out Arc2D outArc
)

Parameters

Name	Type	Default	Description
inArc	const Arc2D&
inReferencePoint	Optional<const Point2D&>	NIL	The point to which the distance of the arc center is changed (no change by default)
inScale	float	1.0f	Scaling factor
inInverse	bool		Switches to the inverse operation
outArc	Arc2D&

Examples

RescaleArc performed on the sample arc, inReferencePoint = auto, inScale = 2.0 and inInverse = false.

Errors

Error type	Description
DomainError	inScale cannot be zero in an inverse scaling in RescaleArc.
