Clipper offset polyline
WebClipper. The Clipper class encapsulates boolean operations on polygons (intersection, union, difference and XOR), which is also called polygon clipping.. Input polygons, both subject and clip sets, are passed to a Clipper object by its AddPath and AddPaths methods, and the clipping operation is performed by calling its Execute method. Multiple boolean … WebClipperLib. Filenames: clipper.pas; clipper.hpp and clipper.cpp; clipper.cs Namespace: ClipperLib Contents

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.
