◆ transformToVectorCoordinates()

Position PositionVector::transformToVectorCoordinates ( const Position p,
bool  extend = false 
) const

return position p within the length-wise coordinate system defined by this position vector. The x value is the same as that returned by nearest_offset_to_point2D(p) and the y value is the perpendicular distance to this vector with the sign indicating the side (right is postive). if extend is true, the vector is extended on both sides and the x-coordinate of the result may be below 0 or above the length of the original vector
