RescalePoint

Changes the distance of a point to a reference point.

Syntax

void fil::RescalePoint
(
	const fil::Point2D& inPoint,
	const fil::Point2D& inReferencePoint,
	float inScale,
	bool inInverse,
	fil::Point2D& outPoint
)

Parameters

	Name	Type	Default	Description
	inPoint	const Point2D&
	inReferencePoint	const Point2D&		Point to which the distance will be changed
	inScale	float	1.0f	Scaling factor
	inInverse	bool		Switches to the inverse operation
	outPoint	Point2D&

In-place Processing

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

Examples

RescalePoint performed on the sample point, inReferencePoint = (150.0, 150.0), inScale = -1.5 and inInverse = false. The inReferencePoint point is drawn on the first image in blue.
