列出Delphi2009win32中可用的GDI+字体

您应该枚举系统中的所有字体:

procedure TPDFFontMapper.EnumFonts;
var
  LF: TLogFont;
begin
  System.FillChar(LF, sizeof(LF), 0);
  LF.lfCharSet := DEFAULT_CHARSET;
  FDC := CreateCompatibleDC(0);
  try
    Windows.EnumFontFamiliesEx(FDC, LF, @EnumFFProc, Integer(Self), 0);
  finally
    Windows.DeleteDC(FDC);
  end;
end;

您应该有一个为每个字体调用的函数,并测试它是否是矢量字体(TrueType和OpenType字体都被视为TrueType字体):

function EnumFFProc(const LogFont: TEnumLogFontEx; const TextMetric: TNewTextMetric; FontType: DWORD; LParam: DWORD): Integer; stdcall;
begin
  if FontType and TRUETYPE_FONTTYPE = TRUETYPE_FONTTYPE then
    // do sometghing useful with the logfont...
  Result := 1;
end;
