How does polyline simplification in Adobe Illustrator work?

问题 I'm working on an application that records strokes, which you paint with a pointing device. In the image above, I've drawn a single stroke, which contains 453 data points. My goal would be to drastically reduce the amount of data points while still maintaining the shape of the original stroke. For those interested, the coordinates for the stroke pictured above are available as a gist on GitHub. As a matter of fact, Adobe Illustrator has a great implementation of what I'm trying to achieve.

Google Maps Polyline click between points

由 心已入冬 提交于 2021-01-28 11:46:06
问题 Using Google Maps api 3, I have a polyline with a click event. I need to find out between which two points in the path the user has clicked. Ideally the index of the points. Below is a sample page mostly taken direct from google docs, but added the click event. The actual app has much more complex polylines. Is there are way to do this? Many thanks <!DOCTYPE html> <html> <head> <meta name="viewport" content="initial-scale=1.0, user-scalable=no"> <meta charset="utf-8"> <title>Polylines</title>
