JXL 사용자 정의 글꼴 설정

Question

JXL에서 사용자 정의 글꼴을 추가하는 방법은 무엇입니까? 기본적으로 제공되는 것 외에도?

public static final FontName ARIAL = new FontName("Arial"); 
public static final FontName TIMES = new FontName("Times New Roman"); 
public static final FontName COURIER = new FontName("Courier New"); 
public static final FontName TAHOMA = new FontName("Tahoma"); 

FontNameWritableFont 클래스는 클래스의 내부 privatestatic 내부 클래스 것으로 보인다. 여기서 언급 한 글꼴과 별도로 글꼴을 추가 할 수 있습니까?

감사합니다, Y.는

Answer 1

WritableFont(WritableFont.FontName fn, int ps) 
     Constructs of font of the specified face and of size given by the specified point size 

Answer 2

글꼴 이름 생성자는 개인이기 때문에 here, 우리는 직접 새 FontName을 인스턴스화 할 수 없습니다를 참조하십시오. 대신 WritableFont.createFont을 사용해야합니다. 이것은 제공된 글꼴 이름으로 지정된 글꼴을 만드는 팩토리 메서드입니다.

는 다음 사항에 유의하시기 바랍니다 :

글꼴 이름을 만드는 데 사용되는 문자열이 Excel의 내부 처리에 의해 인식해야하기 때문에이 방법은주의해서 사용해야합니다

Trebuchet MS 글꼴을 만들려면 단순히 정적 팩터 리 메서드를 호출하면됩니다.

public static final FontName TREBUCHET_MS = WritableFont.createFont("Trebuchet MS");
