Module: FoundationLite

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

Name Type Description
inLine Line2D
inAlignment CoordinateSystem2D Coordinate system to align to
inInverse Bool Switches to the inverse transform
outAlignedLine Line2D


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


AlignLine aligns the inLine to the inAlignment coordinate system. The input line is translated, rotated and scaled.

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


AlignLine performed on the sample line. The inAlignment is drawn on the first image in blue.


This filter can throw an exception to report error. Read how to deal with errors in Error Handling.
