예제

다음 코드 예제를 사용 하는 방법에 설명 합니다 PageScaleTranslateTransform 사각형을 그릴 때 크기와 원점을 변경 하는 멤버입니다.The following code example demonstrates how to use the PageScale and TranslateTransform members to change the scale and origin when you draw a rectangle.

이 예제에서는 Windows Forms를 사용 하 여 사용 하도록 설계 되었습니다.This example is designed to be used with Windows Forms. 양식과 호출 코드를 붙여 합니다 ChangePageScaleAndTranslateTransform 폼을 처리 하는 경우 메서드 Paint 이벤트를 전달 e 으로 PaintEventArgs합니다.Paste the code into a form and call the ChangePageScaleAndTranslateTransform method when handling the form's Paint event, passing e as PaintEventArgs.
