Draw a line, check it against another?

Hey guys! I have a tricky one. Using the “flight plan” or “martian control” method of line drawing I need to figure out a way to have a drawn line be checked for accuracy so it can activate something.

Basically this will be used for tracing letters, but I need to come up with a method for checking that the tracing/line drawing is relatively close to what the software is looking for…

Any ideas? Thanks for the look! [import]uid: 10361 topic_id: 11503 reply_id: 311503[/import]

You need to look at point-reduction algo

Hmm… Yeah this might be helpful. Thanks for bringing it to my attention! Not entirely clear on how I can use this to check against a segment already in place on the screen though. Maybe I’m being a little dense…

Thoughts?

Thanks,
