Instance Method
firstOncurveNodeIndex()firstOncurveNodeIndexfirstOncurveNodeIndex
An index from which every segment can be traversed in node order.
Declaration
func firstOncurveNodeIndex() -> IntDeclaration
- (NSInteger) firstOncurveNodeIndex;Declaration
firstOncurveNodeIndex() -> intDiscussion
For a closed path, the index may be negative to include a segment crossing the array boundary.
Returns 0 for open paths and paths without on-curve nodes.

The index of a node, or
nilwhen the node is not in the path.The next on-curve node after an index.
The previous on-curve node before an index.
For open paths, returns the first node of the path, otherwise
nil.For open paths, returns the last node of the path, otherwise
nil.The node used to begin traversing a closed path, or
nilfor an open path.The lowest on-curve node, preferring the leftmost node at equal height.
Moves trailing off-curve nodes to the beginning of a closed path.
Makes a node the start node of the path.
The index preceding the first on-curve node for TrueType path traversal.
