Hello

I am making a drawing application where I want the user to be able to draw straight lines (quite similar to the line tool in Flash). I want them to be able to draw these lines at any angle they want but they have to be straight and the lengths can only vary between 4 pixels long and 200 pixels long. (The weight of the lines I want to be 2 pixels).

I would be ever so grateful if you could help me out on this,...
