Hi, you might be looking for a bezier thingy, or it might just be as simple as averaging the control points:
If it's the latter, there's some sample source here for something like that: http://objectpainters.com/blog/2007/07/18/drawing-using-controlpoints/ greetz JC On Sat, Nov 15, 2008 at 9:40 PM, Anthony Pace <[EMAIL PROTECTED]> wrote: > I don't know of a good as1/2 lib.
