Header: | FIL.h |
---|---|
Namespace: | fil |
Module: | FoundationLite |
Changes radius of a circle and translates its center in relation to a reference point.
Syntax
C++
C#
void fil::RescaleCircle ( const fil::Circle2D& inCircle, ftl::Optional<const fil::Point2D&> inReferencePoint, float inScale, bool inInverse, fil::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
