Module: FoundationLite

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

Name Type Description
inCircle Circle2D
inAlignment CoordinateSystem2D Coordinate system to align to
inInverse Bool Switches to the inverse transform
outAlignedCircle Circle2D


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.


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.

Complexity Level

This filter is available on Basic Complexity Level.
