== Description ==
Use the OnProcessData event handler to write code that
responds when a data buffer is received.

Write your custom code to process the video data inside the
event. The incoming data will be contained inside the
InBuffer. You can assign the processed data to the OutBuffer.

You can prevent the output buffer to be sent to the next
component by setting SendOutputData to False.

Usually occurs when a new data buffer is generated during
data capturing or data playback.

Delphi Example:

<code>
// Plot the buffer data

procedure TForm1.SLGenericIntProcessData(Sender: TObject;
InBuffer: ISLIntegerBuffer; var OutBuffer: ISLIntegerBuffer; var SendOutputData: Boolean);
var
InDataAccess : ISLIntegerDataAccess;
I : Integer;

begin
Chart1.Series[ 0 ].Clear();
for I := 0 to InBuffer.GetSize() - 1 do
Chart1.Series[ 0 ].Add( InBuffer.Items[ I ], '', clRed );

end;

</code>
C++ Builder Example:

<code>
// Plot the buffer data

void __fastcall TForm1::SLGenericIntProcessData(TObject *Sender,
TSLCIntegerBuffer InBuffer, TSLCIntegerBuffer &OutBuffer,
bool &SendOutputData)
{
Chart1->Series[ 0 ]->Clear();
for( int i = 0; i < InBuffer.GetSize(); i ++ )
Chart1->Series[ 0 ]->Add( InBuffer[ i ], "", clRed );
}

</code>
Visual C++ Example:

<code>
// Plot the buffer data

void __stdcall CCustomFilterDemoDlg::SLGenericIntProcessData(void *Sender,
TSLCIntegerBuffer InBuffer, TSLCIntegerBuffer &OutBuffer,
bool &SendOutputData)
{
for( int i = 0; i < InBuffer.GetSize(); i ++ )
{
int Value = InBuffer[ i ];
// Plot Value using your favorite Chart component.
}
}

</code>
