Class: TSLGenericInt

Syntax
Delphi:
property OnProcessData : TSLProcessIntegerNotify read FOnProcessData write SetOnProcessData;
C++ Builder:
__property TSLProcessIntegerNotify OnProcessData = { read=FOnProcessData, write=SetOnProcessData };
Summary
Occurs when a data buffer is received.
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:
// 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;
C++ Builder Example:
// 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 );
}
Visual C++ Example:
// 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.
}
}
