ImageEnView1.IO.LoadFromFile( 'D:\im.jpg' );
ImageEnView2.IO.LoadFromFile( 'D:\im2.jpg' );

// Allocate destination image
DestIEViewer1.IEBitmap.Allocate( ImageEnView1.IEBitmap.Width, ImageEnView1.IEBitmap.Height );

ImageEnView1.IEBitmap.GetIEVisionImage().cmp( ImageEnView2.IEBitmap.GetIEVisionImage(),
                                              DestIEViewer1.IEBitmap.GetIEVisionImage(),
                                              ievEQUAL );
DestIEViewer1.Update();
