</para>
<!-- ##### TYPEDEF PangoOTTag ##### -->
<para>
The <type>PangoOTTag</type> typedef is used to represent TrueType and OpenType
four letter tags inside Pango. Use the <function>FT_MAKE_TAG()</function> macro
defined in the FreeType2 header <filename>freetype/freetype.h</filename> to
create <type>PangoOTTag</type>s manually.
</para>
<!-- ##### STRUCT PangoOTInfo ##### -->
<para>
The <structname>PangoOTInfo</structname> struct contains the various
tables associated with an OpenType font. It contains only private fields and
should only be accessed via the <function>pango_ot_info_*</function> functions
which are documented below. To obtain a <structname>PangoOTInfo</structname>,
use pango_ot_info_new().
</para>

<!-- ##### STRUCT PangoOTRuleset ##### -->
<para>
The <structname>PangoOTRuleSet</structname> structure holds a
set of features selected from the tables in an OpenType font.
(A feature is an operation such as adjusting glyph positioning
that should be applied to a text feature such as a certain
type of accent.) A <structname>PangoOTRuleSet</structname>
is created with pango_ot_ruleset_new(), features are addded
to it with pango_ot_ruleset_add_feature(), then it is
applied to a #PangoGlyphString with pango_ot_ruleset_shape().
</para>
<!-- ##### ENUM PangoOTTableType ##### -->
<para>
The <type>PangoOTTableType</type> enumeration values are used to
identify the various OpenType tables in the
<function>pango_ot_info_*</function> functions.
</para>
@PANGO_OT_TABLE_GSUB: The GSUB table.
@PANGO_OT_TABLE_GPOS: The GPOS table.
