  FT_EXPORT( FT_Int )
  FT_Has_PS_Glyph_Names( FT_Face  face );

Return true if a given face provides reliable PostScript glyph names. This is similar to using the FT_HAS_GLYPH_NAMES macro, except that certain fonts (mostly TrueType) contain incorrect glyph name tables.

When this function returns true, the caller is sure that the glyph names returned by FT_Get_Glyph_Name are reliable.

Boolean. True if glyph names are reliable.

Retrieve the PS_FontInfoRec structure corresponding to a given PostScript font.

FreeType error code. 0 means success.

The string pointers within the font info structure are owned by the face and don't need to be freed by the caller.

If the font's format is not PostScript-based, this function will return the ‘FT_Err_Invalid_Argument’ error code.

  FT_EXPORT( FT_Error )
  FT_Get_PS_Font_Private( FT_Face     face,
                          PS_Private  afont_private );

Retrieve the PS_PrivateRec structure corresponding to a given PostScript font.

FreeType error code. 0 means success.

The string pointers within the PS_PrivateRec structure are owned by the face and don't need to be freed by the caller.

If the font's format is not PostScript-based, this function returns the ‘FT_Err_Invalid_Argument’ error code.

  FT_Get_PS_Font_Value( FT_Face       face,
                        PS_Dict_Keys  key,

                        FT_Long       value_len );

Retrieve the value for the supplied key from a PostScript font.

The amount of memory (in bytes) required to hold the requested value (if it exists, -1 otherwise).

The values returned are not pointers into the internal structures of the face, but are ‘fresh’ copies, so that the memory containing them belongs to the calling application. This also enforces the ‘read-only’ nature of these values, i.e., this function cannot be used to manipulate the face.

‘value’ is a void pointer because the values returned can be of various types.

If either ‘value’ is NULL or ‘value_len’ is too small, just the required memory size for the requested entry is returned.

The ‘idx’ parameter is used, not only to retrieve elements of, for example, the FontMatrix or FontBBox, but also to retrieve name keys from the CharStrings dictionary, and the charstrings themselves. It is ignored for atomic values.

PS_DICT_BLUE_SCALE returns a value that is scaled up by 1000. To get the value as in the font stream, you need to divide by 65536000.0 (to remove the FT_Fixed scale, and the x1000 scale).

IMPORTANT: Only key/value pairs read by the FreeType interpreter can be retrieved. So, for example, PostScript procedures such as NP, ND, and RD are not available. Arbitrary keys are, obviously, not be available either.

If the font's format is not PostScript-based, this function returns the ‘FT_Err_Invalid_Argument’ error code.
