Syntax
C++
C#
void avl::RescalePoint
(
const avl::Point2D& inPoint,
const avl::Point2D& inReferencePoint,
float inScale,
bool inInverse,
avl::Point2D& outPoint

|
|
|
inReferencePoint |
const Point2D& |
|
Point to which the distance will be changed |
|

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