VImageKit1->FileIO->FileName = "c:\\001.jpg"
VImageKit1->FileIO->FileLoadAsRawData();

// Rawdata -> Stream
VImageKit1.FileIO.SaveToStream(Stream);

// Clear Rawdata
VImageKit1->FileIO->ImageHandleRawData = 0;

// Stream -> Rawdata
Stream->Position = 0; // Reset the head of the stream
VImageKit1->FileIO->LoadFromStream(Stream);

// Rawdata -> File
VImageKit1->FileIO->FileName = "c:\\abc.jpg"
VImageKit1->FileIO->FileSaveAsRawData();

delete Stream;

Delphi
Stream: TMemoryStream;

Stream := TMemoryStream.Create;

VImageKit1.FileIO.FileName := 'c:\001.jpg';
VImageKit1.FileIO.FileLoadAsRawData;

// Rawdata -> Stream
VImageKit1.FileIO.SaveToStream(Stream);

// Clear Rawdata
VImageKit1.FileIO.ImageHandleRawData := 0;
