# TrueType Tables

## Synopsis

This section contains definitions of some basic tables specific to TrueType and OpenType as well as some routines used to access and process them.

## TT_Header

Defined in FT_TRUETYPE_TABLES_H (freetype/tttables.h).

      typedef struct  TT_Header_
      {
        FT_Fixed   Table_Version;
        FT_Fixed   Font_Revision;

        FT_Long    CheckSum_Adjust;
        FT_Long    Magic_Number;

        FT_UShort  Flags;
        FT_UShort  Units_Per_EM;

        FT_ULong   Created [2];
        FT_ULong   Modified[2];

        FT_Short   xMin;
        FT_Short   yMin;

        FT_Short   Reserved[4];

        FT_Short   metric_Data_Format;
        FT_UShort  number_Of_HMetrics;

        /* The following fields are not defined by the OpenType specification */
        /* but they are used to connect the metrics header to the relevant    */
        /* 'hmtx' table.                                                      */

        void*      long_metrics;
        void*      short_metrics;

      } TT_HoriHeader;

A structure to model a TrueType horizontal header, the ‘hhea’ table, as well as the corresponding horizontal metrics table, ‘hmtx’.

#### fields

Version | The table version.
Ascender | The font's ascender, i.e., the distance from the baseline to the top-most of all glyph points found in the font. This value is invalid in many fonts, as it is usually set by the font designer, and often reflects only a portion of the glyphs found in the font (maybe ASCII). You should use the `sTypoAscender` field of the ‘OS/2’ table instead if you want the correct one.
Descender | The font's descender, i.e., the distance from the baseline to the bottom-most of all glyph points found in the font. It is negative. This value is invalid in many fonts, as it is usually set by the font designer, and often reflects only a portion of the glyphs found in the font (maybe ASCII). You should use the `sTypoDescender` field of the ‘OS/2’ table instead if you want the correct one.
Line_Gap | The font's line gap, i.e., the distance to add to the ascender and descender to get the BTB, i.e., the baseline-to-baseline distance for the font.
advance_Width_Max | This field is the maximum of all advance widths found in the font. It can be used to compute the maximum width of an arbitrary string of text.
min_Left_Side_Bearing | The minimum left side bearing of all glyphs within the font.
min_Right_Side_Bearing | The minimum right side bearing of all glyphs within the font.
xMax_Extent | The maximum horizontal extent (i.e., the ‘width’ of a glyph's bounding box) for all glyphs in the font.
caret_Slope_Rise | The rise coefficient of the cursor's slope of the cursor (slope=rise/run).
caret_Slope_Run | The run coefficient of the cursor's slope.
caret_Offset | The cursor's offset for slanted fonts.
Reserved | 8 reserved bytes.
metric_Data_Format | Always 0.
number_Of_HMetrics | Number of HMetrics entries in the ‘hmtx’ table – this value can be smaller than the total number of glyphs in the font.
long_metrics | A pointer into the ‘hmtx’ table.
short_metrics | A pointer into the ‘hmtx’ table.

#### note

For an OpenType variation font, the values of the following fields can change after a call to `FT_Set_Var_Design_Coordinates` (and friends) if the font contains an ‘MVAR’ table: `caret_Slope_Rise`, `caret_Slope_Run`, and `caret_Offset`.

## TT_VertHeader

Defined in FT_TRUETYPE_TABLES_H (freetype/tttables.h).

      typedef struct  TT_VertHeader_

        FT_UShort  advance_Height_Max;      /* advance height maximum */

        FT_Short   min_Top_Side_Bearing;    /* minimum top-sb          */
        FT_Short   min_Bottom_Side_Bearing; /* minimum bottom-sb       */
        FT_Short   yMax_Extent;             /* ymax extents            */
        FT_Short   caret_Slope_Rise;
        FT_Short   caret_Slope_Run;
        FT_Short   caret_Offset;

        FT_Short   Reserved[4];

        FT_Short   metric_Data_Format;
        FT_UShort  number_Of_VMetrics;

        /* The following fields are not defined by the OpenType specification */
        /* but they are used to connect the metrics header to the relevant    */
        /* 'vmtx' table.                                                      */

        void*      long_metrics;
        void*      short_metrics;

      } TT_VertHeader;

A structure used to model a TrueType vertical header, the ‘vhea’ table, as well as the corresponding vertical metrics table, ‘vmtx’.

#### fields

Version | The table version.
Ascender | The font's ascender, i.e., the distance from the baseline to the top-most of all glyph points found in the font.

You should use the `sTypoDescender` field of the ‘OS/2’ table instead if you want the correct one.
Line_Gap | The font's line gap, i.e., the distance to add to the ascender and descender to get the BTB, i.e., the baseline-to-baseline distance for the font.
advance_Height_Max | This field is the maximum of all advance heights found in the font. It can be used to compute the maximum height of an arbitrary string of text.
min_Top_Side_Bearing | The minimum top side bearing of all glyphs within the font.
min_Bottom_Side_Bearing | The minimum bottom side bearing of all glyphs within the font.
yMax_Extent | The maximum vertical extent (i.e., the ‘height’ of a glyph's bounding box) for all glyphs in the font.
caret_Slope_Rise | The rise coefficient of the cursor's slope of the cursor (slope=rise/run).
caret_Slope_Run | The run coefficient of the cursor's slope.
caret_Offset | The cursor's offset for slanted fonts.
Reserved | 8 reserved bytes.

        FT_Short   xAvgCharWidth;
        FT_UShort  usWeightClass;
        FT_UShort  usWidthClass;
        FT_UShort  fsType;
        FT_Short   ySubscriptXSize;
        FT_Short   ySubscriptYSize;

        FT_Short   ySuperscriptXOffset;
        FT_Short   ySuperscriptYOffset;
        FT_Short   yStrikeoutSize;
        FT_Short   yStrikeoutPosition;

        FT_Byte    panose[10];

        FT_ULong   ulUnicodeRange1;        /* Bits 0-31   */
        FT_ULong   ulUnicodeRange2;        /* Bits 32-63  */
        FT_ULong   ulUnicodeRange3;        /* Bits 64-95  */
        FT_ULong   ulUnicodeRange4;        /* Bits 96-127 */

        FT_UShort  usUpperOpticalPointSize;       /* in twips (1/20th points) */

      } TT_OS2;

A structure to model a TrueType ‘OS/2’ table. All fields comply to the OpenType specification.

Note that we now support old Mac fonts that do not include an ‘OS/2’ table. In this case, the `version` field is always set to 0xFFFF.

#### note

For an OpenType variation font, the values of the following fields can change after a call to `FT_Set_Var_Design_Coordinates` (and friends) if the font contains an ‘MVAR’ table: `sCapHeight`, `sTypoAscender`, `sTypoDescender`, `sTypoLineGap`, `sxHeight`, `usWinAscent`, `usWinDescent`, `yStrikeoutPosition`, `yStrikeoutSize`, `ySubscriptXOffset`, `ySubScriptXSize`, `ySubscriptYOffset`, `ySubscriptYSize`, `ySuperscriptXOffset`, `ySuperscriptXSize`, `ySuperscriptYOffset`, and `ySuperscriptYSize`.

Possible values for bits in the `ulUnicodeRangeX` fields are given by the `TT_UCR_XXX` macros.

## TT_Postscript

Defined in FT_TRUETYPE_TABLES_H (freetype/tttables.h).

      typedef struct  TT_Postscript_
      {
        FT_Fixed  FormatType;
        FT_Fixed  italicAngle;
        FT_Short  underlinePosition;
        FT_Short  underlineThickness;
        FT_ULong  isFixedPitch;
        FT_ULong  minMemType42;
        FT_ULong  maxMemType42;
        FT_ULong  minMemType1;
        FT_ULong  maxMemType1;

        /* Glyph names follow in the 'post' table, but we don't */
        /* load them by default.                                */

      } TT_Postscript;

A structure to model a TrueType ‘post’ table. All fields comply to the OpenType specification. This structure does not reference a font's PostScript glyph names; use `FT_Get_Glyph_Name` to retrieve them.

#### note

For an OpenType variation font, the values of the following fields can change after a call to `FT_Set_Var_Design_Coordinates` (and friends) if the font contains an ‘MVAR’ table: `underlinePosition` and `underlineThickness`.

## TT_PCLT

Defined in FT_TRUETYPE_TABLES_H (freetype/tttables.h).

      typedef struct  TT_PCLT_
      {
        FT_Fixed   Version;

        FT_Char    FileName[6];
        FT_Char    StrokeWeight;
        FT_Char    WidthType;
        FT_Byte    SerifStyle;
        FT_Byte    Reserved;

      } TT_PCLT;

A structure to model a TrueType ‘PCLT’ table. All fields comply to the OpenType specification.

## TT_MaxProfile

Defined in FT_TRUETYPE_TABLES_H (freetype/tttables.h).

      typedef struct  TT_MaxProfile_
      {
        FT_Fixed   version;
        FT_UShort  numGlyphs;
        FT_UShort  maxPoints;

        FT_UShort  maxComponentElements;
        FT_UShort  maxComponentDepth;

      } TT_MaxProfile;

## FT_Sfnt_Tag

Defined in FT_TRUETYPE_TABLES_H (freetype/tttables.h).

      typedef enum  FT_Sfnt_Tag_
      {
        FT_SFNT_HEAD,
        FT_SFNT_MAXP,
        FT_SFNT_OS2,
        FT_SFNT_HHEA,
        FT_SFNT_VHEA,
        FT_SFNT_POST,
        FT_SFNT_PCLT,

        FT_SFNT_MAX

      } FT_Sfnt_Tag;

      /* these constants are deprecated; use the corresponding `FT_Sfnt_Tag` */
      /* values instead                                                      */
    #define ft_sfnt_head  FT_SFNT_HEAD
    #define ft_sfnt_maxp  FT_SFNT_MAXP
    #define ft_sfnt_os2   FT_SFNT_OS2
    #define ft_sfnt_hhea  FT_SFNT_HHEA
    #define ft_sfnt_vhea  FT_SFNT_VHEA
    #define ft_sfnt_post  FT_SFNT_POST
    #define ft_sfnt_pclt  FT_SFNT_PCLT

An enumeration to specify indices of SFNT tables loaded and parsed by FreeType during initialization of an SFNT font. Used in the `FT_Get_Sfnt_Table` API function.

#### values

FT_SFNT_HEAD | To access the font's `TT_Header` structure.
FT_SFNT_MAXP | To access the font's `TT_MaxProfile` structure.
FT_SFNT_OS2 | To access the font's `TT_OS2` structure.
FT_SFNT_HHEA | To access the font's `TT_HoriHeader` structure.
FT_SFNT_VHEA | To access the font's `TT_VertHeader` structure.
FT_SFNT_POST | To access the font's `TT_Postscript` structure.
FT_SFNT_PCLT | To access the font's `TT_PCLT` structure.

## FT_Get_Sfnt_Table

Defined in FT_TRUETYPE_TABLES_H (freetype/tttables.h).

      FT_EXPORT( void* )
      FT_Get_Sfnt_Table( FT_Face      face,
                         FT_Sfnt_Tag  tag );

Return a pointer to a given SFNT table stored within a face.

#### input

face | A handle to the source.
tag | The index of the SFNT table.

#### return

A type-less pointer to the table. This will be `NULL` in case of error, or if the corresponding table was not found OR loaded from the file.

Use a typecast according to `tag` to access the structure elements.

#### note

The table is owned by the face object and disappears with it.

This function is only useful to access SFNT tables that are loaded by the sfnt, truetype, and opentype drivers. See `FT_Sfnt_Tag` for a list.

#### example

Here is an example demonstrating access to the ‘vhea’ table.

      TT_VertHeader*  vert_header;

      vert_header =
        (TT_VertHeader*)FT_Get_Sfnt_Table( face, FT_SFNT_VHEA );

## FT_Load_Sfnt_Table

Defined in FT_TRUETYPE_TABLES_H (freetype/tttables.h).

      FT_EXPORT( FT_Error )
      FT_Load_Sfnt_Table( FT_Face    face,
                          FT_ULong   tag,
                          FT_Long    offset,
                          FT_Byte*   buffer,
                          FT_ULong*  length );

Load any SFNT font table into client memory.

#### input

face | A handle to the source face.
tag | The four-byte tag of the table to load. Use value 0 if you want to access the whole font file. Otherwise, you can use one of the definitions found in the `FT_TRUETYPE_TAGS_H` file, or forge a new one with `FT_MAKE_TAG`.
offset | The starting offset in the table (or file if tag == 0).

#### output

buffer | The target buffer address. The client must ensure that the memory array is big enough to hold the data.

#### inout

length | If the `length` parameter is `NULL`, try to load the whole table. Return an error code if it fails. Else, if `*length` is 0, exit immediately while returning the table's (or file) full size in it. Else the number of bytes to read from the table or file, from the starting offset.

#### return

FreeType error code. 0 means success.

#### note

If you need to determine the table's length you should first call this function with `*length` set to 0, as in the following example:

      FT_ULong  length = 0;

      error = FT_Load_Sfnt_Table( face, tag, 0, NULL, &length );
      if ( error ) { ... table does not exist ... }

      buffer = malloc( length );
      if ( buffer == NULL ) { ... not enough memory ... }

      error = FT_Load_Sfnt_Table( face, tag, 0, buffer, &length );
      if ( error ) { ... could not load table ... }

Note that structures like `TT_Header` or `TT_OS2` can't be used with this function; they are limited to `FT_Get_Sfnt_Table`. Reason is that those structures depend on the processor architecture, with varying size (e.g. 32bit vs. 64bit) or order (big endian vs. little endian).

## FT_Sfnt_Table_Info

Defined in FT_TRUETYPE_TABLES_H (freetype/tttables.h).

      FT_EXPORT( FT_Error )
      FT_Sfnt_Table_Info( FT_Face    face,
                          FT_UInt    table_index,
                          FT_ULong  *tag,
                          FT_ULong  *length );

Return information on an SFNT table.

#### input

face | A handle to the source face.
table_index | The index of an SFNT table. The function returns FT_Err_Table_Missing for an invalid value.

#### inout

tag | The name tag of the SFNT table. If the value is `NULL`, `table_index` is ignored, and `length` returns the number of SFNT tables in the font.

#### output

length | The length of the SFNT table (or the number of SFNT tables, depending on `tag`).

#### return

FreeType error code. 0 means success.

#### note

While parsing fonts, FreeType handles SFNT tables with length zero as missing.

## FT_Get_CMap_Language_ID

Defined in FT_TRUETYPE_TABLES_H (freetype/tttables.h).

      FT_EXPORT( FT_ULong )
      FT_Get_CMap_Language_ID( FT_CharMap  charmap );

Return cmap language ID as specified in the OpenType standard. Definitions of language ID values are in file `FT_TRUETYPE_IDS_H`.

#### input

charmap | The target charmap.

#### return

The language ID of `charmap`. If `charmap` doesn't belong to an SFNT face, just return 0 as the default value.

For a format 14 cmap (to access Unicode IVS), the return value is 0xFFFFFFFF.

## FT_Get_CMap_Format

Defined in FT_TRUETYPE_TABLES_H (freetype/tttables.h).

      FT_EXPORT( FT_Long )
      FT_Get_CMap_Format( FT_CharMap  charmap );

Return the format of an SFNT ‘cmap’ table.

#### input

charmap | The target charmap.

#### return

The format of `charmap`. If `charmap` doesn't belong to an SFNT face, return -1.

## FT_PARAM_TAG_UNPATENTED_HINTING

    #define FT_PARAM_TAG_UNPATENTED_HINTING \
              FT_MAKE_TAG( 'u', 'n', 'p', 'a' )

Deprecated, no effect.

    #define TT_PLATFORM_ADOBE          7 /* artificial */

A list of valid values for the `platform_id` identifier code in `FT_CharMapRec` and `FT_SfntName` structures.

#### values

TT_PLATFORM_APPLE_UNICODE | Used by Apple to indicate a Unicode character map and/or name entry. See `TT_APPLE_ID_XXX` for corresponding `encoding_id` values. Note that name entries in this format are coded as big-endian UCS-2 character codes only.
TT_PLATFORM_MACINTOSH | Used by Apple to indicate a MacOS-specific charmap and/or name entry. See `TT_MAC_ID_XXX` for corresponding `encoding_id` values. Note that most TrueType fonts contain an Apple roman charmap to be usable on MacOS systems (even if they contain a Microsoft charmap as well).
TT_PLATFORM_ISO | This value was used to specify ISO/IEC 10646 charmaps. It is however now deprecated. See `TT_ISO_ID_XXX` for a list of corresponding `encoding_id` values.
TT_PLATFORM_MICROSOFT | Used by Microsoft to indicate Windows-specific charmaps. See `TT_MS_ID_XXX` for a list of corresponding `encoding_id` values. Note that most fonts contain a Unicode charmap using (`TT_PLATFORM_MICROSOFT`, `TT_MS_ID_UNICODE_CS`).
TT_PLATFORM_CUSTOM | Used to indicate application-specific charmaps.
TT_PLATFORM_ADOBE | This value isn't part of any font format specification, but is used by FreeType to report Adobe-specific charmaps in an `FT_CharMapRec` structure. See `TT_ADOBE_ID_XXX`.

Possible values of the language identifier field in the name records of the SFNT ‘name’ table if the ‘platform’ identifier code is `TT_PLATFORM_MICROSOFT`. These values are also used as return values for function `FT_Get_CMap_Language_ID`.

The canonical source for Microsoft's IDs is

https://docs.microsoft.com/en-us/windows/desktop/Intl/language-identifier-constants-and-strings ,

however, we only provide macros for language identifiers present in the OpenType specification: Microsoft has abandoned the concept of LCIDs (language code identifiers), and format 1 of the ‘name’ table provides a better mechanism for languages not covered here.

More legacy values not listed in the reference can be found in the `FT_TRUETYPE_IDS_H` header file.
