| Value | Meaning |
|---|---|
| FromStart0 | The tangent in path direction of the incoming side of the path |
| ToStart1 | The tangent against path direction of the incoming side of the path |
| ToEnd2 | The tangent in path direction of the outgoing side of the path |
| FromEnd3 | The tangent against path direction of the outgoing side of the path |
The values of the gsk.types.PathDirection enum are used to pick one of the four tangents at a given point on the path.
Note that the directions for @GSK_PATH_FROM_START/@GSK_PATH_TO_END and @GSK_PATH_TO_START/@GSK_PATH_FROM_END will coincide for smooth points. Only sharp turns will exhibit four different directions.
