RescaleSegment

Lengthens or shortens a segment relatively.

Syntax

void fil::RescaleSegment
(
	const fil::Segment2D& inSegment,
	ftl::Optional<const fil::Point2D&> inReferencePoint,
	float inScale,
	bool inInverse,
	fil::Segment2D& outSegment
)

Parameters

Name	Type	Default	Description
inSegment	const Segment2D&
inReferencePoint	Optional<const Point2D&>	NIL	The point to which all distances change linearly (the mass center by default)
inScale	float	1.0f	Scaling factor (negative values invert the segment)
inInverse	bool		Switches to the inverse operation
outSegment	Segment2D&

Examples

RescaleSegment performed on the sample segment, inReferencePoint = auto, inScale = 2.0 and inInverse = false.
