Difference Functions
2D Regularized Boolean Set-Operations Reference

Each one of these functions computes the difference between two given polygons p1 and p2, and inserts the resulting polygons with holes into an output container through the output iterator oi. The value type of the OutputIterator is either Polygon_with_holes_2 or General_polygon_with_holes_2.

The signature of the function is

OutputIterator difference(const Type1 & p1, const Type2 & p2, OutputIterator oi);

Parameters

The types of the paramters of the difference() function are any of the following combinations.
