Hi,

close enough to
that bezier curve to register a hit, on a mouse click?
CD does not have functions like that, it is a simple graphics library. Such
questions don't usually be solved by graphics libraries. Foley is a great
reference, Graphics Gems is another.
I would search for algorithms and implement myself...
