Syntax
HRESULT SetOutputSize( [in] DWORD _dwWidth, [in] DWORD _dwHeight );

Return Values
| Return code | Description |
| S_OK | Success. |
| S_FALSE | The size is the same. |
| VFW_E_TYPE_NOT_ACCEPTED | Downstream filter does not support this resolution. |
Remarks
If _dwWidth and _dwHeight are zero, default output size will be set. (Default output size is the size of the maximum input frame.)
