closePath()
Closes and terminates the current path’s subpath.
Declaration
func closePath()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 CGContextMoveToPoint. In this case, a new subpath is implicitly created with a starting and current point equal to the previous subpath’s starting point.
If the current path is empty or the current subpath is already closed, this function does nothing.
