HasProperIntersection

A proper intersection is an intersection which is interior to at least two line segments. Note that a proper intersection is not necessarily in the interior of the entire Geometry, since another edge may have an endpoint equal to the intersection, which according to SFS semantics can result in the point being on the Boundary of the Geometry.

Declaration
public bool HasProperIntersection { get; }
Property Value

bool

ProcessIntersections(ISegmentString, int, ISegmentString, int)

This method is called by clients of the ISegmentIntersector class to process intersections for two segments of the ISegmentString being intersected.
Note that some clients (such as MonotoneChain") may optimize away this call for segment pairs which they have determined do not intersect (e.g. by an disjoint envelope test).

Declaration
public void ProcessIntersections(ISegmentString e0, int segIndex0, ISegmentString e1, int segIndex1)
Parameters
Type Name Description
ISegmentString e0
int segIndex0
ISegmentString e1
int segIndex1
