How can I display fonts correctly?

Foxit PDF SDK provides the interface of FSCRT_Library_AddFontFile or FSCRT_Library_SetFontMapperHandler to display fonts.

Following is a sample to show how to use FSCRT_Library_SetFontMapperHandler in C++.

static FSCRT_FONTMAPPERHANDLER ExternalFontMapper; 
static string FallbackFontPath; 

// MapExternalFont function will be triggered when an external font is needed. 

static FS_RESULT MapExternalFont(FS_LPVOID clientData, FS_LPCSTR fontName, FS_DWORD 
fontStyles, FS_INT32 weight, FS_INT32 charset, FSCRT_FILE *fontFile, FS_INT32 *faceIndex) 
{ 

/* The values of fontName, fontStyles, weight, charset will be provided. The setting of 
fontFile is depending on programmer. An simple example is to set it to randomFontName*/ 

if(fontName=="randomFontName") {//set font file randomFontName.ttf}. 

/*Set the font file. Call FSCRT_File_Create with FSCRT_File_Write, 
FSCRT_File_CreateCacheFile, FSCRT_File_CreateFromMemory, or FSCRT_File_CreateFromFileName 
to create the handle for FSCRT_FILE. Please see fs_base_r.h or fs_codec_r.h for details. 
//faceIndex can be set to 0 for default*/ 

Return 0; 
} 

//Apply the font mapper after unlocking the library. 

ExternalFontMapper.MapFont = MapExternalFont; 

ExternalFontMapper.clientData = 0; 

//clientData is your own data that you want to pass to MapExternalFont when it is triggered 

FSCRT_Library_SetFontMapperHandler (&ExternalFontMapper);
