◆ unifyDirectionBy()

void WLine::unifyDirectionBy ( const WLine & other )

Put the line into reverse ordering if the reverse ordering would have a similar direction to the given line.

That means if the start point (or multiple selected sample points) of the given line will better match to end point (or multiple selected sample points) of this line (in term of direction) the line is reordered.

Parameters

other The line giving the direction to align this line to.
