Method Detail

addPosition

public void addPosition(double x,
                        double y)

Adds a position point to this step at the specified image coordinates.

Parameters:

x - the image x coordinate of the position point

y - the image y coordinate of the position point

getPosition1

public TPoint getPosition1()
