Inputs

Name	Type	Description
ipPoints	ITcVnContainer	Container with TcVnPoint2_DINT, TcVnPoint2_REAL, or TcVnPoint2_LREAL elements
ipDestImage	ITcVnImage	Destination image
nThickness	DINT	Line thickness (if negative, the shape is filled)
bIsClosed	BOOL	If it is true, the function draws a line from the last point to the first point to close the polygon.
eLineType	ETcVnLineType	Line type
nShift	UDINT	Fractional bits of the coordinates (bit shift)
hrPrev	HRESULT	HRESULT indicating the result of previous operations (If SUCCEEDED(hrPrev) equals false, no operation is executed.)
