예제
다음 코드 예제는 Windows Forms에서 사용하도록 설계되었으며 Paint 이벤트 개체인 PaintEventArgse
필요합니다. 코드는 다음 작업을 수행합니다.
사각형을 형성하는 점의 배열을 만듭니다.
배율 변환(파란색 사각형)을 적용하기 전에 화면에 이 점 배열을 그립니다.
행렬을 만들고 x축에서 3, y축에서 2로 크기를 조정하고 두 축에서 100으로 변환합니다.
화면에 행렬 요소를 나열합니다.
이 행렬 변환을 점 배열에 적용합니다.
변환된 배열을 화면(빨간색 사각형)에 그립니다.
빨간색 사각형은 직사각형의 왼쪽 위 모서리(사각형의 시작점)를 포함하여 x축에서 3배, y축에서 2로 배율 조정되었지만 변환 벡터(행렬의 마지막 두 요소)는 무시됩니다.
