Hi,
I have to draw a shape moving round over an image like a car moving over a track drawing. The shape to be drawn will be many (20-30). I was thinking of loading the background image and then drawing the line to be followed then to be converted into a list of points (how?) to be used as coordinates to draw the shape.
What is the best solution?
Is there a function that allows me to do this movement in a certain time?
Do I draw a shape each layer?
Do I change the coordinates of the shapes on the same image?
I have developed such a thing in the past but I wanted to improve it with these components.
Thanks for the tips!

Hi

Performance is going to be the main issue here. If you are likely to be repainting multiple times a second, it will be hard to have it look good.

I would try using layers for shapes:

Update all the positions of your layers, and then call ImageEnView1.Update() to refresh the view.

Ensure you cache your layers:
