# FontNamesFiltersEnum

FontNamesFiltersEnum enumeration constants describe predefined filters of font family names. These filters specify the set of fonts to be used during document synthesis.

```
typedef enum {
 FNF_All        = 0x00000001,
 FNF_Auto       = 0x00000002,
 FNF_Arabic     = 0x00000004,
 FNF_Armenian   = 0x00000008,
 FNF_Chinese    = 0x00000010,
 FNF_European   = 0x00000020,
 FNF_Japanese   = 0x00000040,
 FNF_Hebrew     = 0x00000080,
 FNF_Korean     = 0x00000100,
 FNF_Thai       = 0x00000200,
 FNF_FineReader = 0x00000400,
 FNF_PDF        = 0x00000800,
 FNF_None       = 0
} FontNamesFiltersEnum;
