예제

다음 코드 예제에서는 Matrix 및 Transform 메서드를 사용하여 문자열을 회전하는 방법을 보여 줍니다. 이 예제는 Windows Forms와 함께 사용하도록 설계되었습니다. 양식을 만들고 다음 코드를 붙여넣습니다. 양식의 Paint 이벤트 처리기에서 DrawVerticalStringFromBottomUp 메서드를 호출하여 ePaintEventArgs전달합니다.

RotateAt(Single, PointF, MatrixOrder)

Source:

Matrix.cs

지정된 지점에 대한 시계 방향 회전을 지정된 순서로 이 Matrix 적용합니다.

public:
 void RotateAt(float angle, System::Drawing::PointF point, System::Drawing::Drawing2D::MatrixOrder order);

public void RotateAt (float angle, System.Drawing.PointF point, System.Drawing.Drawing2D.MatrixOrder order);

member this.RotateAt : single * System.Drawing.PointF * System.Drawing.Drawing2D.MatrixOrder -> unit

Public Sub RotateAt (angle As Single, point As PointF, order As MatrixOrder)

매개 변수

angle

Single

회전 각도(도)입니다.

point

PointF

회전의 중심을 나타내는 PointF.

order

MatrixOrder

회전이 적용되는 순서(추가 또는 앞에 추가)를 지정하는 MatrixOrder.

예제

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

• 회전 변환(파란색 사각형)을 적용하기 전에 화면에 사각형을 그립니다.

• 행렬을 만들고 지정된 지점을 45도 회전합니다.

• 이 행렬 변환이 사각형에 적용됩니다.

• 변환된 사각형을 화면(빨간색 사각형)에 그립니다.

빨간색 사각형이 사각형의 왼쪽 위 모서리를 중심으로 회전되었습니다(회전 지점은 RotateAt 메서드를 지정).
