matchFont matches a pattern of font characteristics and returns the closest match if possible. If a match was found the FastPrintFontInfo passed in as parameter will be update to the found matching font.

implementation note: currently the function is only implemented for fontconfig.

@param rInfo out of the FastPrintFontInfo structure the following fields will be used for the match:
  • family name
  • italic
  • width
  • weight
  • pitch
@param rLocale if rLocal contains non empty strings the corresponding locale will be used for font matching also; e.g. "Sans" can result in different fonts in e.g. english and japanese */ void matchFont( FastPrintFontInfo& rInfo, const css::lang::Locale& rLocale ); static std::unique_ptr getFontOptions( const FastPrintFontInfo&, int nSize); void Substitute(FontSelectPattern &rPattern, OUString& rMissingCodes); }; } // namespace #endif // INCLUDED_VCL_INC_FONTMANAGER_HXX /* vim:set shiftwidth=4 softtabstop=4 expandtab: */ iledrendering3'>feature/calctiledrendering3 LibreOffice 核心代码仓库文档基金会
