정의

System.Windows.Media

어셈블리:

PresentationCore.dll

지정한 Point에 직선을 그립니다.

public:
 abstract void LineTo(System::Windows::Point point, bool isStroked, bool isSmoothJoin);

public abstract void LineTo (System.Windows.Point point, bool isStroked, bool isSmoothJoin);

abstract member LineTo : System.Windows.Point * bool * bool -> unit

Public MustOverride Sub LineTo (point As Point, isStroked As Boolean, isSmoothJoin As Boolean)

매개 변수

point

Point

선의 끝에 대한 대상 점입니다.

isStroked

Boolean

세그먼트를 렌더링하기 위해 Pen을 사용할 때 세그먼트에 스트로크를 설정하려면 true이고, 그렇지 않으면 false입니다.

isSmoothJoin

Boolean

Pen을 사용하여 스트로크를 설정할 때 이 세그먼트와 이전 세그먼트 간의 연결을 모퉁이로 처리하려면 true이고, 그렇지 않으면 false입니다.

예외

InvalidOperationException

BeginFigure(Point, Boolean, Boolean) 메서드를 호출하여 그림을 시작하지 않고 세그먼트를 추가하려고 시도한 경우

설명

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.
