This class implements the output pin of a simple transform filter. It is the class assigned to the m_pOutput data member of the CTransformFilter class.
Typically, you can create objects of a class derived from CTransformFilter without modifying the CTransformOutputPin class.
To override this class and derive a class from CTransformFilter, use the class and then override the CTransformFilter::GetPin member function to create pins of your derived class.
Protected Data Members
| Member | Description |
|---|---|
m_pTransformFilter |

Pointer to a CPosPassThru object that implements the IMediaPosition interface to pass media position commands on to the upstream filter. |
Member Functions
| Member function | Description |
|---|---|
Constructs a CTransformOutputPin object. |
|
Retrieves the media type currently assigned to the filter. |
Overrideable Member Functions
| Member function | Description |
|---|---|
Informs the derived class when the connection is broken. |
|
