Hi When you draw in macromedia flash, you can toggle "smothing" of freehand lines on and off. when on, flash "rounds" off the points on your hand-drawn path to make them smooth. You could say it makes even the worst drawn figures much better by removing sharp edges. I saw an example written in blitzbasic for this (not you fathers basic, so i havent been able to convert it) called smoth polybezier. Im no good at beziers, but it seemed to peek ahead in the array of TPoints to calculate hinting. Does anyone have any code for somthing like this?

While i am a great admirer of you work (you have helped me out on god knows how many occations), graphics programming is just a hobby. Everything i make end up as public domain anyway. Once in a while i find some things i just dont know how to do (like this bezier thing) - but i ever rarely buy components. Sorry. PS: I have sent a few customers to your site, the scrollbox component seems to be in demand. (yes, i did figure it out..)

Hi Jon Lennart Aasenden, I have posted a small sample of an algorithem that does what you want in the attachment group. If you improve it I would like a copy :) send to roymagne @ rmklever.com (remove spaces) Kind Regards Roy Magne Klever Back to top Jon Lennart Aasenden Guest Posted: Fri Oct 28, 2005 5:40 am    Post subject: Re: Smoth PolyBezier line? Hi Roy Well, it was just what i was looking for! But i found Nils's name in the code... (isnt that ironic). Hope you did not break any copyrights here. Nils.. have you started answering posts by pure mind control? :) Either way, i will have a closer look at it. Thank you for helping me out.

Hi Jon Lennart, Quote: Well, it was just what i was looking for! Good! Quote: But i found Nils's name in the code... (isnt that ironic). Well there are others DP routines on the net but I used it because it is MPL. BTW I have great respect for Nils work, he have better soultuions than me but I share my experience in hope of gettting at the same level as Nils :) Quote: Hope you did not break any copyrights here.

Hi Jon, Nope, Roy kept himself perfectly to the MPL license :) He used another free piece of code I wrote for Douglas-Peucker line simplification. However, that doesn't use bezier segments, but just line segments. The extension that Roy wrote was to convert these line segments back to bezier segments. While this is a nice solution, it inhibits one problem: you generally don't know if the error specified is really honoured. So specifying a max error of 5 pixels for DP, could turn out to be larger/smaller for the bezier segments. My other code (commercial) solves this problem. If you contact me by email, I'll provide you with a copy for free though. I only want money from C++ guys in this case, not from regular posters here :) Nils "Jon Lennart Aasenden" <post_nospam_nojunk (AT) jurasoft (DOT) no> schreef in bericht news:4361b917 (AT) newsgroups (DOT) borland.com...
