매개 변수

ranges

CharacterRange[]

MeasureCharacterRanges(String, Font, RectangleF, StringFormat) 메서드 호출로 측정된 문자 범위를 지정하는 CharacterRange 구조체의 배열입니다.

예외

OverflowException

32자 이상의 문자 범위가 설정됩니다.

예제

다음 예제는 Windows Forms에서 사용하도록 설계되었으며 Paint 이벤트 처리기의 매개 변수인 PaintEventArgse필요합니다. 코드는 다음 작업을 수행합니다.

• StringFormat문자 범위를 설정합니다.

• 지정된 문자열 및 레이아웃 사각형의 문자 범위를 측정합니다.

• 문자열 및 레이아웃 사각형을 그립니다.

• 영역을 그립니다. 각 Region 문자 범위가 차지하는 영역을 지정합니다. 영역의 값은 문자 범위가 MeasureCharacterRanges 메서드에 의해 측정되는 경우 설정됩니다.

• 처음 네 단계를 반복하지만 각 문자 범위의 측정에 후행 공백이 포함됩니다.

• 후행 공백이 각 문자 범위의 측정값에 포함되지 않도록 StringFormat 서식 플래그를 지웁니다.

• 처음 네 단계를 반복하지만 다른 레이아웃 사각형을 사용하여 레이아웃 사각형이 문자 범위의 측정값에 영향을 줍니다. 글꼴의 크기도 측정값에 영향을 미칩니다.
