You have to set object properties then call AddNewObject. For example:

ImageEnVect1.AddNewObject(iekLINE, Rect(0,0,200,80), clBlack);

Thanks for helping me solve the problem above. There is another question , how to draw a vector line on a layer ? As i want to move the layer by using the mouse.

Property ObjLayer[] specifies the object layer (where it is displayed and the base of its coordinates).
Assuming you have a layer 1 (the layer just over the background layer), you can create a line over it writing:

ImageEnVect1.ObjLayer[-1] := 1;
ImageEnVect1.AddNewObject(iekLINE, Rect(0,0,200,80), clBlack);


Index -1 means "index of next object that is created.
