add Invert function in xy package
jackielii opened this issue · comments
A Invert function can enable the linear ring to transform from CCW to CW and vise versa, which is makes construct a proper polygon easier.
Makes sense, but I'd call the function Reverse. It should be a method on geom1 (LineStrings and LinearRings).
I was borrowing from https://godoc.org/github.com/golang/geo/s2#Loop.Invert
I will probably implement it in the next few days. Will submit a PR if you don't mind
Yes, please do.
