Class Boolean2

Namespace: GeometryHelper.Core

Assembly: GeometryHelper.dll

The boolean operations over the loops that may curve.

These flatten first, and say so by what they give back: Clipper resolves every region operation in this library and knows only straight edges, so there is no form of a boolean that keeps arcs. The straight result is the honest one — an answer of the curved type would be a promise that the arcs had survived, and they have not.

Offset2 is the exception, and the reason is worth knowing: offsetting is done piece by piece, so an arc can be offset exactly and stay an arc. A boolean cannot be done piece by piece.
