The TrueType and OpenType specifications allow the inclusion of a special names table (‘name’) in font files. This table contains textual (and internationalized) information regarding the font, like family name, copyright, version, etc.

The definitions below are used to access them if available.

Note that this has nothing to do with glyph names!

### FT_SfntName

Defined in FT_SFNT_NAMES_H (freetype/ftsnames.h).

      typedef struct  FT_SfntName_
      {
        FT_UShort  platform_id;
        FT_UShort  encoding_id;
        FT_UShort  language_id;
        FT_UShort  name_id;

        FT_Byte*   string;      /* this string is *not* null-terminated! */
        FT_UInt    string_len;  /* in bytes                              */

      } FT_SfntName;

A structure used to model an SFNT ‘name’ table entry.

#### fields

platform_id | The platform ID for ‘string’. See TT_PLATFORM_XXX for possible values.
encoding_id | The encoding ID for ‘string’. See TT_APPLE_ID_XXX, TT_MAC_ID_XXX, TT_ISO_ID_XXX, TT_MS_ID_XXX, and TT_ADOBE_ID_XXX for possible values.

language_id

The language ID for ‘string’. See TT_MAC_LANGID_XXX and TT_MS_LANGID_XXX for possible values.

Registered OpenType values for ‘language_id’ are always smaller than 0x8000; values equal or larger than 0x8000 usually indicate a language tag string (introduced in OpenType version 1.6). Use function FT_Get_Sfnt_LangTag with ‘language_id’ as its argument to retrieve the associated language tag.

name_id | An identifier for ‘string’. See TT_NAME_ID_XXX for possible values.
string | The ‘name’ string. Note that its format differs depending on the (platform,encoding) pair, being either a string of bytes (without a terminating NULL byte) or containing UTF-16BE entities.
string_len | The length of ‘string’ in bytes.

#### note

Please refer to the TrueType or OpenType specification for more details.

### FT_Get_Sfnt_Name_Count

Defined in FT_SFNT_NAMES_H (freetype/ftsnames.h).

      FT_EXPORT( FT_UInt )
      FT_Get_Sfnt_Name_Count( FT_Face  face );

Retrieve the number of name strings in the SFNT ‘name’ table.

#### input

face | A handle to the source face.

#### return

The number of strings in the ‘name’ table.

### FT_Get_Sfnt_Name

Defined in FT_SFNT_NAMES_H (freetype/ftsnames.h).

      FT_EXPORT( FT_Error )
      FT_Get_Sfnt_Name( FT_Face       face,
                        FT_UInt       idx,
                        FT_SfntName  *aname );

Retrieve a string of the SFNT ‘name’ table for a given index.

#### input

face | A handle to the source face.
idx | The index of the ‘name’ string.

#### output

aname | The indexed FT_SfntName structure.

#### return

FreeType error code. 0 means success.

#### note

The ‘string’ array returned in the ‘aname’ structure is not null-terminated. Note that you don't have to deallocate ‘string’ by yourself; FreeType takes care of it if you call FT_Done_Face.

Use FT_Get_Sfnt_Name_Count to get the total number of available ‘name’ table entries, then do a loop until you get the right platform, encoding, and name ID.

‘name’ table format 1 entries can use language tags also, see FT_Get_Sfnt_LangTag.

### FT_SfntLangTag

Defined in FT_SFNT_NAMES_H (freetype/ftsnames.h).

      typedef struct  FT_SfntLangTag_
      {
        FT_Byte*  string;      /* this string is *not* null-terminated! */
        FT_UInt   string_len;  /* in bytes                              */

      } FT_SfntLangTag;

A structure to model a language tag entry from an SFNT ‘name’ table.

#### fields

string | The language tag string, encoded in UTF-16BE (without trailing NULL bytes).
string_len | The length of ‘string’ in bytes.

#### note

Please refer to the TrueType or OpenType specification for more details.

### FT_Get_Sfnt_LangTag

Defined in FT_SFNT_NAMES_H (freetype/ftsnames.h).

      FT_EXPORT( FT_Error )
      FT_Get_Sfnt_LangTag( FT_Face          face,
                           FT_UInt          langID,
                           FT_SfntLangTag  *alangTag );

Retrieve the language tag associated with a language ID of an SFNT ‘name’ table entry.

#### input

face | A handle to the source face.
langID | The language ID, as returned by FT_Get_Sfnt_Name. This is always a value larger than 0x8000.

#### output

alangTag | The language tag associated with the ‘name’ table entry's language ID.

#### return

FreeType error code. 0 means success.

#### note

The ‘string’ array returned in the ‘alangTag’ structure is not null-terminated. Note that you don't have to deallocate ‘string’ by yourself; FreeType takes care of it if you call FT_Done_Face.

Only ‘name’ table format 1 supports language tags. For format 0 tables, this function always returns FT_Err_Invalid_Table. For invalid format 1 language ID values, FT_Err_Invalid_Argument is returned.

### FT_PARAM_TAG_IGNORE_TYPOGRAPHIC_FAMILY

Defined in FT_SFNT_NAMES_H (freetype/ftsnames.h).

    #define FT_PARAM_TAG_IGNORE_TYPOGRAPHIC_FAMILY \
              FT_MAKE_TAG( 'i', 'g', 'p', 'f' )

      /* this constant is deprecated */
    #define FT_PARAM_TAG_IGNORE_PREFERRED_FAMILY \
              FT_PARAM_TAG_IGNORE_TYPOGRAPHIC_FAMILY

A tag for FT_Parameter to make FT_Open_Face ignore typographic family names in the ‘name’ table (introduced in OpenType version 1.4). Use this for backward compatibility with legacy systems that have a four-faces-per-family restriction.

### FT_PARAM_TAG_IGNORE_TYPOGRAPHIC_SUBFAMILY

Defined in FT_SFNT_NAMES_H (freetype/ftsnames.h).

    #define FT_PARAM_TAG_IGNORE_TYPOGRAPHIC_SUBFAMILY \
              FT_MAKE_TAG( 'i', 'g', 'p', 's' )

      /* this constant is deprecated */
    #define FT_PARAM_TAG_IGNORE_PREFERRED_SUBFAMILY \
              FT_PARAM_TAG_IGNORE_TYPOGRAPHIC_SUBFAMILY

A tag for FT_Parameter to make FT_Open_Face ignore typographic subfamily names in the ‘name’ table (introduced in OpenType version 1.4). Use this for backward compatibility with legacy systems that have a four-faces-per-family restriction.
