We have been trying for some time now to come up with an algorithm to outline
an image using a series of bezier curves (ie to use with postscript). The 
problem we are facing is that we have a series of points that describe the
outline but cannot find an algorithm to produce the beziers from these points.
The algorithms i have seen all assume that the control points are known for the
bezier curve to be fitted.

Does anybody know of an algorithm to evaluate the control points for a bezier
curve that best fits a set of points? If anyone has seen a documented 
description of an algorithm i would dearly love to hear about it. 

If anyone can help me with this problem, please e-mail to me. If there is 
sufficient response, i will post a summary in this news group.

thankyou in advance
Con Neri
