Hello,
when using layers there is the following problem see example pictures.
1. Original Imageenview1.center := true
2. With Layer1 and softshadow.enabled := true;
3. Mergelayer(0,1);
Problem, the Picture not more in center, posx and psy < 0
4. Set posx,posy = 0, it's Ok now
5. Original + Layer1 imageenview1.center := false;
6. Softshadow.enabled = true, Mergelayer(0,1)
Problem, left and top Site not visible
7. Posx,posy = 0, It's Ok
Maybe this could be corrected. Then you don't have to correct it every time.

Hi Klaus
In the first state, the view is centered over layer 0 (which appears to be a blank 1x1 image), and layer 1 is ignored.
After you merge it is now centered on your layer 1 + layer 2 combined, so it is expected to move.
It is easier to see if you make Layer 0 visible, e.g.
ImageEnView1.Layers[0].Bitmap.Allocate(10, 10, clRed);
ImageEnView1.Update;
This is why ImageEnView1.Center is not recommended for layer editing.
Also see loDynamicCanvas in LayerOptions:

Hi Nigel,
loDynamicCanvas is not practical for me.
When moving, unpredictable views arise.
If center := false, it doesn't work.
I set after mergelayer, posx and posy = 0.
The result is better.
