yes I found the formula for straight lines and I was wondering what was the one for bezier curves, so your reply could not have come a better moment. Thanks I will study it and implement it.

You may want to calculate the distance between the mouse position and your path (I guess a bezier curve). Then given this distance and a tolerance to zero you decide if the mouse position is more or less on your path. Calculating the distance you will also get for free the place where to add a point on your path.

In order to do that I will have to check that the line passes through a specific pixel. Or to be more correct that the place that mouse has clicked is where my path passes through. How I do that ? Can Athens do that ? Can athens tell me which pixels my path passes through ?
