RescaleCircle

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

Syntax

void avl::RescaleCircle
(
	const avl::Circle2D& inCircle,
	atl::Optional<const avl::Point2D&> inReferencePoint,
	float inScale,
	bool inInverse,
	avl::Circle2D& outCircle
)

void RescaleCircle
(
	Circle2D inCircle,
	Point2D? inReferencePoint,
	float inScale,
	bool inInverse,
	out Circle2D outCircle
)

Parameters

Name	Type	Default	Description
inCircle	const Circle2D&
inReferencePoint	Optional<const Point2D&>	NIL	The point to which the distance of the circle center is changed (no change by default)
inScale	float	1.0f	Scaling factor
inInverse	bool		Switches to the inverse operation
outCircle	Circle2D&

Examples

RescaleCircle performed on the sample circle, inReferencePoint = auto, inScale = 0.5 and inInverse = false.

Errors

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