Brenor Brophy

This package can be used to perform different types of geometric operations with polygons.

It provides generic polygon and vertex classes that support mixing lines and arc segments between vertices. Polygons may be self-intersecting.

It provides means to perform boolean operations AND and OR (Intersect and Union) with the shapes and compute shape clipping (A-B and B-A).

Number 5

Prize: One book of choice by SAMS		 Certain types of image manipulation applications need to execute operations on images that involve shapes, for instance to define clipping areas. Such areas are defined by individual polygons or combinations of multiple polygons.

This class provides means to perform operations on shapes defined by polygons delimited by lines or arcs. It is useful for image manipulation applications like, for instance, those that involve maps.
