Constructs a CTransformFilterobject.
CTransformFilter( TCHAR* pObjectName, LPUNKNOWN lpUnk, CLSID clsid );
Parameters
- pObjectName
- Name given to the CTransformFilterobject.
- lpUnk
- Pointer to LPUNKNOWN.
- clsid
- Class identifier of the
CTransformFilterclass.
Return Values
No return value.
Remarks
The constructor of the derived class calls this member function. The pin objects are not created at this time; they are created when calling the CTransformFilter::GetPinmember function. Thus the pins ( m_pInputand m_pOutput) cannot be referred to in the constructor unless GetPinis first called. (An external object can find pins only by enumerating them or by calling IBaseFilter::FindPin. These each call GetPin, so the pins are, in fact, created as soon as they are needed.)
