A way to reduce the number of points to describe graphical shapes and to get nice, smooth lines.
Implements Lang Simplification and McMaster’s Slide Averaging Algorithm.
Try the demo:
Line Generalization AS2

(developed and published originally in 2005)

Update: AS3 version of the core classes (without Demo-Editor):
Line Generalization AS3

hi andreas,
i have seen your small master of pieces, like this one and the gradient tool !
i’m the author of flashpaint, and i’m studying some good stuff around for a newer version of the application in as2 or 3.
i have also a tool to generate code from any flashpaint drawing, i have to publish that once.
this line tool could be very suitable to generate less data to send to the server !
where did you find informations for these algorithms ?
CGI books ?
bye.

@Fred3d
Thanks for your kind words!

The purpose and principle of Lang Simplification and McMaster’s Slide Averaging Algorithm are perfectly explained in this tutorial:
http://www.sli.unimelb.edu.au/gisweb/LGmodule/LGSelect.htm (thanks to Jim Cheng for pointing this out).
As I’m not at all a Math guy that’s exactly the kind of explanation – visual, common sense – I needed to be able to recreate it in ActionScript.

I find flashpaint.com impressive – keep up the good work!

Hi Andreas!
Thanks a lot for this script that implement the simplification and averaging algorithms. Since i’ve been trying to make it work in Actionscript 3 for two days now and i still fail:

Is there any possibility that you post a – AS3-version of LineGeneralization?

Sure, find the Link to the AS3 source in the updated post above. Cheers!

Hello, really cool work, i`m playing around with some drawing stuff, this class is really helpful for me. IÂ´m getting an error when compiling, because the vars are not strongtyped

example: var len = points.length;

Am i doing wrong, or should i strongtype them anyway?

Thanks for sharing your stuff

Greetings from Vienna
