[geos-devel] strange behavior with offsetCurve, resulting points get resorted

[Swen Zanon]

Hi,

what i would expect is shown here: http://onmaps.de/tmp/wcqs5aay.png
(modified your image a bit).

Ok, forget what i wrote about "first point gets into the middle" :-)
The image explains my problem, i think.

With best regards,
Swen

The two geometries you show are offsetted on the right side,
thus order is reverted.

Here's a screenshot: http://strk.keybit.net/tmp/circlces.png

I don't understand what you say about first point getting into the
middle of the resulting geometry.
