## Values

| Name | Value | Description |
| --- | --- | --- |
| Disjoint | 0 | There is no common area between the two regions. |
| MutualIntersection | 1 | The two curves intersect. There is therefore no full containment relationship either way. |
| AInsideB | 2 | Region bounded by curveA (first curve) is inside of curveB (second curve). |
| BInsideA | 3 | Region bounded by curveB (second curve) is inside of curveA (first curve). |
