var
vect: TImageEnVect;

begin
vect:= TMyImageEnVect.Create(Self);
vect.Parent:=Self;
vect.Align:= alClient;
vect.AddNewObject(iekBOX, Rect(10,10,100,100), clRed);
end;

When using this code, not create any object. Canvas is white.

When ImageEnVect is created at runtime it looks like it is important to create a bitmap before adding an object:
procedure TForm1.FormCreate(Sender: TObject);
var
  hobj: integer;
begin
  ImageEnVect := TImageEnVect.Create(self);
  ImageEnVect.Parent := self;
  ImageEnVect.Left := 0;
  ImageEnVect.Top := 0;
  ImageEnVect.Align := alClient;
  ImageEnVect.Background := clBtnFace;
  ImageEnVect.BorderStyle := bsSingle;
  ImageEnVect.BackgroundStyle := iebsSolid;
  ImageEnVect.IEBitmap.Allocate(640, 480); // Important  
  ImageEnVect.IEBitmap.Fill(clBtnFace);
  ImageEnVect.Update;
  ImageEnVect.AddNewObject(iekBOX, Rect(10, 10, 100, 100), clRed);
end;
