Recognizing Shapes?

[rob5]

Hi,

I am very new to developing for the Tablet PC. My question is this:

Can I develop a program which recognizes shapes that are drawn, such as squares, circles, triangles, etc. and then "smoothes" the shapes once they are recognized? Does something like this already exist?

Any help would be appreciated. Thanks.

Hi Rob

Something like this does exist.

You could look at Corel Grafigo.

There is also a way to do it in Windows Journal.

Draw something like this, then use the lasso tool to select it.

This sounds like riteShape
http://www.penandinternet.com/piweb/...s_prodinfo.asp

I've never used it, but I use ritePen by the same people, which I love.

Thanks for the info.

So, I am looking to incorporate this functionality in an application that I am writing. Do you know if there is a way that I can do this sort of "automatically". So, the user draws a circle, the circle is recognized as a circle, and then this circle is redrawn as a smooth, perfect circle approximately the same size.

Hi,

Did you solve this problem?
I am investigating this as an alternative to using Graphics.DrawShape on a Tablet PC application.

Thanks,
Janine

The company which used to do SketchRight is offering the technology for licensing.

http://www.saltire.com was the URL I believe.
