Enumeration Type Documentation

◆ ClipResult

These values indicate the result of clipping an input segment against a bounding box.

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

The possible values describe if and how two segments intersect.

Enumerator
SIT_UNINITIALIZED	Invalid value
SIT_NONE	No intersection
SIT_SEGMENT	Collinear intersection (intersection is a non-degenerate segment).
SIT_POINT	Intersection at a single point (not at the endpoints).
SIT_ENDPOINT	Intersection occurs at a common endpoint of the two segments.
