Description: The Clipper Library is based on but significantly extends Bala Vatti s polygon clipping algorithm as described in "A generic solution to polygon clipping", Communications of the ACM, Vol 35, Issue 7 (July 1992) pp 56-63.
The library can perform each of the four boolean clipping operations- intersection, union, difference and exclusive-or (xor). It can accept any number of, and any type of polygon as input (including self-intersecting polygons). Duplicate vertices and coincident edges are also accommodated.
Polygon holes are handled implicitly, based on polygon orientation. Polygon holes are implied by having their orientations opposite the orientation of their container polygons.
The Clipper package contains the core library, a help file and a number of compiled examples. The library s code was initially written in Delphi Pascal (and compiles in version 7 and up) but now contains C++ and C# translations too. The code in each language is a little over 100K, or about 3500 li
