Enumeration Type Documentation

ClipResult

enum ClipResult

Enumerator
CR_INVALID	Can't compute a result, call setLimit() with a valid Bbox2 before!
CR_EMPTY	The result is empty (input completely outside the box)
CR_CLIPPED_DEGENERATE	The result has been clipped and is degenerate
CR_CLIPPED_NONDEGENERATE	The result has been clipped and is non-degenerate
CR_COMPLETE_DEGENERATE	The result is unclipped and degenerate (because the segment was already degenerate)
CR_COMPLETE_NONDEGENERATE	The result is unclipped and non-degenerate

SegmentIntersectionType

enum SegmentIntersectionType

The Segment intersection type enumerates the way two line segments intersect each other

Enumerator
SIT_UNINITIALIZED	Invalid value
SIT_NONE	No intersection
SIT_SEGMENT	The intersection is a non-degenerate segment (collinear intersection)
SIT_POINT	The intersection is a single point differnt from the endpoints
SIT_ENDPOINT	The two segments share a common endpoint which is the only intersection
