Header: FIL.h
Namespace: fil

Changes the corners and the dimensions of a rectangle.

Syntax

void fil::RescaleRectangle
(
	const fil::Rectangle2D& inRectangle,
	ftl::Optional<const fil::Point2D&> inReferencePoint,
	float inScale,
	bool inInverse,
	fil::Rectangle2D& outRectangle
)

Parameters

Name Type Default Description
Input value
 inRectangle const Rectangle2D&
Input value
 inReferencePoint Optional<const Point2D&> NIL The point, to which all distance will be changed proportionally
Input value
 inScale float 1.0f Scaling factor
Input value
 inInverse bool Switches to the inverse operation
