Syntax

VB.Net
C#
Delphi
C++

Sub MFTransition( _
   ByVal _pFrameFrom As IMFFrame, _
   ByRef _ppFrameRes As IMFFrame, _
   ByVal _dblPos As Double, _
   ByVal _bsTransition As String, _
   ByVal _bsPropsList As String, _
   ByVal _bsConverterID As String _
)

void MFTransition( 
   IMFFrame _pFrameFrom,
   out IMFFrame _ppFrameRes,
   double _dblPos,
   string _bsTransition,
   string _bsPropsList,
   string _bsConverterID
)

procedure MFTransition( 
    _pFrameFrom: IMFFrame;
   Out  _ppFrameRes: IMFFrame;
    _dblPos: Double;
    _bsTransition: String;
    _bsPropsList: String;
    _bsConverterID: String
);

void MFTransition( 
   IMFFrame* _pFrameFrom,
   [PARAMFLAG::Out] IMFFrame* _ppFrameRes,
   double _dblPos,
   BSTR* _bsTransition,
   BSTR* _bsPropsList,
   BSTR* _bsConverterID
)

Parameters

_pFrameFrom: a frame from the transition is used
_ppFrameRes: result frame
_dblPos: position of a transition
_bsTransition: transition type
_bsPropsList: additional properties
_bsConverterID: converter ID

Example

Here is a example of how to use a transition from File transition sample:

/// <summary>
/// Make a transition between frames
/// </summary>
/// <param name="pFrameTo">frame to which transition is implemented</param>
/// <param name="pFrameFrom">frame from which transition is implemented</param>
/// <param name="_dblPos">transition's position</param>
/// <param name="_strConverterID">converter's ID</param>
private void FrameTransition(ref MFFrame pFrameTo, MFFrame pFrameFrom, double _dblPos, string _strConverterID)
{
    MFFrame pFrameRes = null;
    pFrameTo.MFTransition(pFrameFrom, out pFrameRes, _dblPos, "fade", "", _strConverterID);
    if (pFrameRes != null)
    {
        Marshal.ReleaseComObject(pFrameTo);
        pFrameTo = pFrameRes;
    }
}
