예제

다음 코드 예제는 Windows Forms에서 사용하도록 설계되었으며 OnPaint 이벤트 개체인 PaintEventArgse필요합니다. 코드는 다음 작업을 수행합니다.

• 새 LinearGradientBrush만듭니다.

• 이 브러시를 사용하여 화면에 줄임표를 그립니다.

• MultiplyTransform 메서드를 호출하여 LinearGradientBrush변환합니다.

• 변형된 브러시를 사용하여 첫 번째 줄임표 바로 아래의 화면에 줄임표를 그립니다.

• 변환을 다시 설정합니다.

• 처음 두 줄임표 아래의 화면에 세 번째 줄임표를 그립니다.

가장 낮은 줄임표는 첫 번째와 같은 크기로 그려지고 ResetTransform 메서드 호출로 인해 그라데이션이 일치하도록 감소되었습니다.
