Header: AVL.h
Namespace: avl
Module: FoundationLite

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

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


void avl::AlignCircle
	const avl::Circle2D& inCircle,
	const avl::CoordinateSystem2D& inAlignment,
	bool inInverse,
	avl::Circle2D& outAlignedCircle


Name Type Default Description
Input value
inCircle const Circle2D&
Input value
inAlignment const CoordinateSystem2D& Coordinate system to align to
Input value
inInverse bool Switches to the inverse transform
Output value
outAlignedCircle Circle2D&

In-place Processing

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

Read more about In-place Computation.


AlignCircle aligns the inCircle to the inAlignment coordinate system. The input circle is translated, rotated and scaled.

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


AlignCircle performed on the sample circle. The inAlignment is drawn on the first image in blue.
