Boolean operations on composite polygons and clips.
Classes BooleanFHP and BooleanGH
are composites and provide boolean operations
intersection, difference,
reverse-difference, sum and
union.
Note: A clip is defined as a single, usually closed polygon, a composite is a collection of one or more clips.
See Also: Forster-Hormann-Popa and Greiner-Hormann.
Version: 23.04.02

_LatLonBool (INTERNAL) Base class for LatLonFHP and LatLonGH. |

|
LatLonFHP A point or intersection in a BooleanFHP clip or composite. |

|
_Clip (INTERNAL) A doubly-linked list representing a closed polygon of LatLonFHP or LatLonGH points, duplicates and intersections with other clips. |
|
|
_CompositeBase (INTERNAL) Base class for BooleanFHP and BooleanGH ( _CompositeFHP and
_CompositeGH).
|
|
|
_CompositeFHP (INTERNAL) A list of clips representing a composite of LatLonFHP points, duplicates and intersections with an other composite. |
|
|
_CompositeGH (INTERNAL) A list of clips representing a composite of LatLonGH points, duplicates and intersections with an other composite. |
