NAME

Math::Geometry::Planar::GPC - Perl wrapper for Alan Murta’s gpc library

CONTENTS

SYNOPSIS

use Math::Geometry::Planar::GPC;

Description

This module is just a wrapper around the gpc C library written by Alan Murta

gpc: General Polygon Clipping library (C) 1997-1999, Advanced Interfaces Group, University of Manchester.

Please refer to the gpc manual for more details on gpc.
