이 Transform에 적용된 DrawingGroup을 가져오거나 설정합니다.

public:
 property System::Windows::Media::Transform ^ Transform { System::Windows::Media::Transform ^ get(); void set(System::Windows::Media::Transform ^ value); };

public System.Windows.Media.Transform Transform { get; set; }

Public Property Transform As Transform

속성 값

Transform

이 DrawingGroup에 적용할 변환입니다. 기본값은 null입니다.

예제

적용 하는 방법을 보여 주는이 예제는 Transform 에 Drawing합니다. 변환할를 Drawing 개체에 추가 DrawingGroup 설정를 Transform 의 속성을 DrawingGroup 개체.

합니다 DrawingGroup 클래스의 유일한 형식인 Drawing 변환을 지 원하는 개체입니다. 단일에 여러 변환을 적용 하려면 DrawingGroup를 사용 하 여를 TransformGroup입니다.

다음 예에서는 DrawingGroup 여러 결합 GeometryDrawing 개체를 사용 하 여 변환 합니다는 RotateTransform합니다.

그림과 합니다 DrawingGroup 전과 후의 RotateTransform 적용 됩니다.
