Delphi 구문:

procedure SetFont ( FontName: AnsiString; FontStyle: TFontStyles; ASize: Single; FontCharset: TFontCharset = DEFAULT_CHARSET; IsVertiacal: Boolean);

TFontStyles Definition

Determines whether the font is normal, italic, underlined, bold, and so on

type

  TFontStyle = (fsBold, fsItalic, fsUnderline, fsStrikeOut);

  TFontStyles = set of TFontStyle;

Description:
Use Style to add special characteristics to characters that use the font. Style is a set containing zero or more values from the following:

Value	Meaning

fsBold	The font is boldfaced
fsItalic	The font is italicized
fsUnderline	The font is underlined
fsStrikeOut	The font is displayed with a horizontal line through it.

TFontCharset Definition

TFontCharset represents the character set of a font

type TFontCharSet = 0..255;

Description:
Each Windows typeface supports one or more character sets, which indicate what characters can be written using the font. For example, most fonts that can represent japanese characters use a particular multi-byte character set
Each font supports its own, unique set of character sets. Check with the font vendor to determine which character sets are supported

ANSI_CHARSET		0	ANSI characters
DEFAULT_CHARSET		1	Font is chosen based solely on Name and Size

C++ 구문:

void __fastcall SetFont ( AnsiString FontName, Graphics::TFontStyles FontStyle, float ASize, Graphics::TFontCharset FontCharset; IsVertiacal: Boolean);

 

Description:

SetFont method는 text output을 위한 current font를 설정합니다. FontStyle은 0개 이상의 style flag를 포함하고 ASize는 font size를 정의합니다

 

서로 다른 font 사이를 전환할 때 HotPDF는 이전 font의 cached Unicode glyph state를 reset하고 active font의 glyph ID와 width를 resolve합니다. 이는 Calibri 및 기타 TrueType Unicode font 같은 embedded font에 중요합니다

 

Viewer 전반에서 repeatable output을 얻으려면 SetFont 호출 전에 THotPDF.FontEmbedding을 enable하고 THotPDF.StandardFontEmulation을 disable하십시오

 

FontEmbedding이 enabled이면 HotPDF는 embedded TrueType font program의 PostScript name을 resolve하고 matching PDF font name을 씁니다. 이렇게 하면 SetFont에 전달된 Windows face name이 alias 또는 substituted face여도 /BaseFont/FontDescriptor data가 일관되게 유지됩니다

 

Code Example

program TextOut;
{$APPTYPE CONSOLE}
uses
    SysUtils, Graphics, Classes, HPDFDoc;

var
    HPDF: THotPDF;

begin
    HPDF := THotPDF.Create ( nil ) ;
    try
        HPDF.AutoLaunch := true;
        HPDF.FileName := 'TextOut.pdf';
        HPDF.FontEmbedding := true;
        HPDF.StandardFontEmulation := false;
        HPDF.BeginDoc;
        HPDF.CurrentPage.SetFont('Calibri', [fsBold], 24);
        HPDF.CurrentPage.TextOut(10, 10, 0, 'Embedded font output');
        HPDF.EndDoc;
    finally
        HPDF.Free;
    end;
end.
