AlignSegment


Header: FIL.h
Namespace: fil
Module: FoundationLite

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

Applications: Required when there is a segment 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::AlignSegment
(
	const fil::Segment2D& inSegment,
	const fil::CoordinateSystem2D& inAlignment,
	bool inInverse,
	fil::Segment2D& outAlignedSegment
)

Parameters

Name Type Default Description
Input value inSegment const Segment2D&
Input value inAlignment const CoordinateSystem2D& Coordinate system to align to
Input value inInverse bool Switches to the inverse transform
Output value outAlignedSegment Segment2D&

In-place Processing

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

Read more about In-place Computation.

Description

AlignSegment aligns the inSegment to the inAlignment coordinate system. The input segment is translated, rotated and scaled.

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

Examples

AlignSegment performed on the sample segment. The inAlignment is drawn on the first image in blue.
