Enum PolygonRelation

Enumerates the types of spatial relationships between two polygons, A and B, based on the positions of their vertices.

Namespace: OpenSvg

Assembly: OpenSvg.dll

Syntax

public enum PolygonRelation

Remarks

Note: Border-touching vertices are treated as "neutral" and do not by themselves determine the relationship. The relationship is assessed based on the positions of the other vertices.

The relationships are symmetric, meaning:

• If A is Inside B, then B Cover A.
• If A is Disjoint from B, then B is Disjoint from A.
• If A Intersect B, then B Intersect A.
• If A is Equal to B, then B is Equal to A.

Fields

Name	Description
Cover	All vertices of B are within the interior of A. Any border-touching vertices are not considered.
Disjoint	No part of A overlaps with B. Any border-touching vertices are not considered.
Equal	Both polygons have the same vertices and are identical in shape and position.
Inside	All vertices of A are within the interior of B. Any border-touching vertices are not considered.
Intersect	At least one vertex of A is inside the interior of B, or vice versa. Any border-touching vertices are not considered.
