방법: Drawing에 GuidelineSet 적용
업데이트: 2007년 11월
이 예제에서는 DrawingGroup에 GuidelineSet을 적용하는 방법을 보여 줍니다.
DrawingGroup 클래스는 GuidelineSet 속성이 있는 유일한 형식의 Drawing입니다. 다른 형식의 Drawing에 GuidelineSet을 적용하려면 DrawingGroup에 추가한 다음 해당 DrawingGroup에 GuidelineSet을 적용합니다.
예제
다음 예제에서는 거의 동일한 두 개의 DrawingGroup 개체를 만듭니다. 두 번째 DrawingGroup에는 GuidelineSet이 있고 첫 번째 개체에는 이 속성이 없다는 점만 다릅니다.
다음 그림에서는 이 예제를 실행한 결과를 보여 줍니다. 두 DrawingGroup 개체의 렌더링된 모양에 별다른 차이가 없어 보이므로 그리기의 일부를 확대해서 보여 줍니다.
