AlignPoint


Moves a point from a local coordinate system to the absolute one.

Header:AVL.h

Syntax

C++
C#
 
void avl::AlignPoint
(
	const avl::Point2D& inPoint,
	const avl::CoordinateSystem2D& inAlignment,
	bool inInverse,
	avl::Point2D& outAlignedPoint
)

Parameters

Name Type Default Description
inPoint const Point2D&
inAlignment const CoordinateSystem2D& Coordinate system to align to
inInverse bool Switches to the inverse transform
outAlignedPoint Point2D&

Description

AlignPoint aligns the inPoint to the inAlignment coordinate system. The input point is translated, rotated and scaled.

The inAlignment is usually a coordinate system found by some template matching algorithm.

Examples

AlignPoint performed on the sample point. The inAlignment 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 outAlignedPoint
