Instance Method

closeSubpath()

Closes and completes a subpath in a mutable graphics path.

Declaration

func closeSubpath()

Parameters

path

The path to change.

Discussion

Appends a line from the current point to the starting point of the current subpath and ends the subpath.

After closing the subpath, your application can begin a new subpath without first calling moveTo(_:x:y:). In this case, a new subpath is implicitly created with a starting and current point equal to the previous subpath’s starting point.
