AlignPoint


Header: FIL.h
Namespace: fil
Module: FoundationLite

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

Applications: Required when there is a point defined in a local coordinate system, but the next image-related filter in the program does not have any inAlignment input.

Syntax

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

Parameters

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

In-place Processing

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

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.
