Pointlist to Bezier?

Pointlist to Bezier

Hi there

I wonder if any have code to take a point-list and turn it into a smooth-lined bezier.

There are explanations around the net for C-code but it is very hard to understand.

(one here said to be good but misses the graphics:)

What could this code be used for.

— Tracing an image

— Smoothing the lines drawn by a user

plus a lot more Im sure

Thanks 
Michael
