Type

Description

ipSrcPointsCart

ITcVnContainer

Container with cartesian points (ContainerType_Vector_TcVnPoint2_DINT or ContainerType_Vector_TcVnPoint2_REAL or ContainerType_Vector_TcVnPoint2_LREAL)

ipDestPointsPolar

Reference To ITcVnContainer

Returns a container which is filled with the converted points in polar coordinates (ContainerType_Vector_TcVnPoint2_REAL, if source points are of type TcVnPoint2_DINT or TcVnPoint2_REAL; else ContainerType_Vector_TcVnPoint2_LREAL. Non-zero interface pointers are reused.)

hrPrev

HRESULT

HRESULT indicating the result of previous operations (If SUCCEEDED(hrPrev) equals false, no operation is executed.)
