public LineProfileCommand( 
   LeadPoint firstPoint,
   LeadPoint secondPoint
)

'Declaration

)

function LineProfileCommand( 
   firstPoint ,
   secondPoint 
)

public:
LineProfileCommand( 
   LeadPoint firstPoint,
   LeadPoint secondPoint
)

Parameters

firstPoint: The starting point for the line.
secondPoint: The end point for the line.
