libmath-clipper-perl - 1.27-1+b1 main

Math::Clipper is a C++ (and Delphi) library that implements polygon
clipping. A Polygon is represented by a reference to an array of 2D
points. A Point is, in turn, represented by a reference to an array
containing two numbers: The X and Y coordinates.
.
Clipper 4.x works with polygons with integer coordinates. Data in
floating point format will need to be scaled appropriately to be
converted to the available integer range before polygons are added to a
clipper object. (Scaling utilities are provided.)
