Here, I copy a 100x100 region from Image1 to Image2 when the user clicks on Image1

procedure TForm1.Image1MouseDown(Sender: TObject; Button: TMouseButton;
  Shift: TShiftState; X, Y: Integer);
begin
  Image2.Canvas.CopyRect(Rect(0, 0, 100, 100),
    Image1.Canvas,
    Rect(X, Y, X + 100, Y + 100));
end;
