방법: 합성 그리기 만들기
이 예제에서는 DrawingGroup을 통해 여러 Drawing 개체를 단일 합성 그리기로 결합하여 복잡한 그리기를 만드는 방법을 보여 줍니다.
예제
다음 예제에서는 DrawingGroup을 사용하여 GeometryDrawing 및 ImageDrawing 개체로 합성 그리기를 만듭니다. 다음 그림에서는 이 예제가 만들어내는 결과를 보여 줍니다.

new SolidColorBrush(Color.FromArgb(102, 181, 243, 20)),

new EllipseGeometry(new Point(50,50), 50, 50)
);

// Create a DrawingGroup to contain the drawings.

DrawingGroup을 사용하면 포함된 그리기에 Transform, Opacity 설정, OpacityMask, BitmapEffect, ClipGeometry 또는 GuidelineSet을 적용할 수 있습니다. DrawingGroup도 Drawing이기 때문에 다른 DrawingGroup 개체를 포함할 수 있습니다.
다음 예제는 이전 예제와 유사하지만 추가 DrawingGroup 개체를 사용하여 일부 그리기에 비트맵 효과와 불투명 마스크를 적용했습니다. 다음 그림에서는 이 예제가 만들어내는 결과를 보여 줍니다.
