# AlignPath

Header: AVL.h avl FoundationLite

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

Applications: Required when there is a path 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 avl::AlignPath
(
const avl::Path& inPath,
const avl::CoordinateSystem2D& inAlignment,
bool inInverse,
avl::Path& outAlignedPath
)


### Parameters

Name Type Default Description
inPath const Path& Input path
inAlignment const CoordinateSystem2D& Coordinate system to align to
inInverse bool Switches to the inverse transform
outAlignedPath Path&

### In-place Processing

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

### Description

AlignPath aligns the inPath to the inAlignment coordinate system. The input path is translated, rotated and scaled.

The inAlignment is usually an alignment of an object found by some template matching algorithm.

### Examples

AlignPath run on the sample paths.
