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
)

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&

In-place Processing

This function supports in-place data processing - you can pass the same reference to inCircle and outCircle

Examples

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