◆ FindFont()

FONTCONFIG::FF_RESULT FONTCONFIG::FindFont ( const wxString &  aFontName,
wxString &  aFontFile,
int &  aFaceIndex,
bool  aBold,
bool  aItalic,
const std::vector< wxString > *  aEmbeddedFiles = nullptr 
)

Given a fully-qualified font name ("Times:Bold:Italic") find the closest matching font and return its filepath in aFontFile.

A return value of false indicates a serious error in the font system.

◆ getAllFamilyStrings()

void FONTCONFIG::getAllFamilyStrings ( FONTCONFIG_PAT &  aPat,
std::unordered_map< std::string, std::string > &  aFamStringMap 
)
private

Gets a list of all family name strings maped to lang.

Parameters
aPatreference to FcPattern container
aFamStringMapMap to be populated with key, value pairs representing lang to family name

◆ getFamilyStringByLang()

std::string FONTCONFIG::getFamilyStringByLang ( FONTCONFIG_PAT &  APat,
const wxString &  aDesiredLang 
)
private

Gets a family name based on desired language.

This will fallback to english or first available string if no language matching string is found.

Parameters
aPatreference to FcPattern container
aDesiredLangLanguage to research for (RFC3066 format)

◆ getFcString()

std::string FONTCONFIG::getFcString ( FONTCONFIG_PAT &  aPat,
const char *  aObj,
int  aIdx 
)
private

Wrapper of FcPatternGetString to return a std::string.

Parameters
aPatreference to FcPattern container
aObjThe fontconfig property object like FC_FAMILY, FC_STYLE, etc
aIdxThe ith value associated with the property object

◆ isLanguageMatch()

bool FONTCONFIG::isLanguageMatch ( const wxString &  aSearchLang,
const wxString &  aSupportedLang 
)
private

Matches the two rfc 3306 language entries, used for when searching for matching family names.

The overall logic is simple, either both language tags matched exactly or one tag is "single" level that the other language tag contains. There's nuances to language tags beyond this but font tags will most likely never be more complex than say "zh-CN" or single tag "en".

Parameters
aSearchLangthe language being searched for
aSupportedLangthe language being offered

◆ ListFonts()

void FONTCONFIG::ListFonts ( std::vector< std::string > &  aFonts,
const std::string &  aDesiredLang,
const std::vector< wxString > *  aEmbeddedFiles = nullptr,
bool  aForce = false 
)

List the current available font families.

Parameters
aDesiredLangThe desired language of font name to report back if available, otherwise it will fallback
aEmbeddedFilesA list of embedded to use for searching fonts, if nullptr, this is not used
aForceIf true, force rebuilding the font cache

◆ SetReporter()

void fontconfig::FONTCONFIG::SetReporter ( REPORTER *  aReporter)
static

Set the reporter to use for reporting font substitution warnings.

Parameters
aReporterThe reporter to use for reporting font substitution warnings.
