Clipper2

A Polygon Clipping and Offsetting library (in C++, C# & Delphi)

The Clipper2 library performs intersection, union, difference and XOR boolean operations on both simple and complex polygons. It also performs polygon offsetting. This is a major update of my original Clipper library that was written over 10 years ago. That library I'm now calling Clipper1, and while it still works very well, Clipper2 is better in just about every way.

Compilers

Clipper2 can be compiled using either C++, or C#, or Delphi Pascal. The library can also be accessed from other programming languages by dynamically linking to exported functions in the C++ compiled Clipper2 library. (Since the C++ compiled code is measurably faster, C# and Delphi developers may also prefer this approach in applications where the library's performance is critical.)

Lang.	Requirements
C++:	Requires C++17 (could be modified to C++11 with relatively minor changes), or
C#:	The library uses Standard Library 2.0 but the sample code uses .NET6, or
Delphi:	Compiles with any version of Delphi from version 7 to current.
