fab	Posted - Nov 21 2011 : 10:48:47 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.
diaorp	Posted - Nov 21 2011 : 06:42:28 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.
fab	Posted - Nov 21 2011 : 01:11:10 You have to set object properties then call AddNewObject. For example: ImageEnVect1.AddNewObject(iekLINE, Rect(0,0,200,80), clBlack);
