매개 변수
- isSmoothJoin
- Boolean
Pen을 사용하여 스트로크를 설정할 때 이 세그먼트와 이전 세그먼트 간의 연결을 모퉁이로 처리하려면 true
이고, 그렇지 않으면 false
입니다.
예외
BeginFigure(Point, Boolean, Boolean) 메서드를 호출하여 그림을 시작하지 않고 세그먼트를 추가하려고 시도한 경우

설명
첫 번째 지점 points
첫 번째 제어점을 지정 합니다. 다음 두 번째 제어점을 지정, 세 번째 점과 끝점을 지정 하 고, 다음 점이 다음 곡선의 첫째 제어점을 지정 합니다.
이 메서드는 시작 지점으로 이전 세그먼트의 끝점을 사용 합니다. 이 그림에서 첫 번째 세그먼트를 통해 지정한 점을 사용 합니다 BeginFigure 메서드 시작 지점으로 합니다.
A StreamGeometry 포함 된 경우 직렬화 할 수 없습니다는 Transform 스트로크 되지 않은 모든 또는 채워지지 않은 세그먼트입니다.
