속성 값

형식: System.Drawing.Region
컨트롤과 연결된 창 Region입니다.

설명

해당 창 영역 운영 체제 활성화 드로잉 창의 픽셀 컬렉션입니다.운영 체제는 창 영역 밖에 있는 창 부분은 표시 하지 않습니다.컨트롤 영역의 좌표는 컨트롤의 클라이언트 영역이 아니라 컨트롤의 왼쪽 위 모퉁이를 기준으로 합니다.

예제

다음 예제에서는 Region 속성을 변경 하려면는 RectangleShape 반투명 타원이에.이 예제에서는 있어야는 RectangleShape 폼에 RectangleShape1 이라는.이미지에 반투명 효과 확인 하려면 할당의 BackgroundImage 폼의 속성입니다.
