WebJan 21, 2024 · Tolerance must be well chosen and is scale dependent. So don’t use a too small tolerance because calculation will be very long. And if it is not that you must check if you provide a “good” polyline to Clipper, it is best to do that with a dedicated component than to rely on automatic conversion. http://www.angusj.com/delphi/clipper/documentation/Docs/Units/ClipperLib/Classes/ClipperOffset/_Body.htm lawrence county recovery ohio

WebTo preserve this degree of floating point precision, and given that Clipper and ClipperOffset both operate on integer coordinates, the polygon coordinates will be scaled up by 108 (and rounded to integers) prior to offsetting. Both offset delta and ArcTolerance will also need to be scaled by this same factor.
