속성 값

InkCanvas의 기본 그리기 특성입니다.

예제

다음 예제에서는 두 DrawingAttributes 개체를 사용하여 동일한 InkCanvas에서 펜과 형광펜을 사용하는 환경을 시뮬레이션하는 방법을 보여 줍니다. 이 예제에서는 XAML(태그 언어) 파일 DockPanel 의 루트 요소가 라는 root것으로 가정합니다. 또한 호출 switchHighlighter 이 Button 있고 이벤트가 이벤트 처리기에 연결되어 있다고 Click 가정합니다.

다음 예제에서는 DefaultDrawingAttributes 속성을 데이터 원본에 바인딩하는 방법을 보여 줍니다.

이 속성을 설정하면 이 속성이 설정된 후에 수행되는 새 스트로크에만 영향을 줍니다. 이미 만든 Stroke 개체에 새 그리기 특성을 적용하려면 속성을 사용하여 Strokes 개별적으로 액세스합니다.
