Classes
| Info |
|
| Ruleset |
The PangoOTRuleset structure holds a set of features selected
from the tables in an OpenType font.
|
Structs
| Buffer |
|
| FeatureMap |
The PangoOTFeatureMap typedef is used to represent an OpenType
feature with the property bit associated with it. The feature tag is
represented as a char array instead of a PangoOTTag for convenience.
since: 1.18
|
| Glyph |
The PangoOTGlyph structure represents a single glyph together with
information used for OpenType layout processing of the glyph.
It contains the following fields.
|
| RulesetDescription |
The PangoOTRuleset structure holds all the information needed
to build a complete PangoOTRuleset from an OpenType font.
The main use of this struct is to act as the key for a per-font
hash of rulesets. The user populates a ruleset description and
gets the ruleset using pango_ot_ruleset_get_for_description()
or create a new one using pango_ot_ruleset_new_from_description().
since: 1.18
|
Aliases
| Tag |
The PangoOTTag typedef is used to represent TrueType and OpenType
four letter tags inside Pango. Use PANGO_OT_TAG_MAKE()
or PANGO_OT_TAG_MAKE_FROM_STRING() macros to create PangoOTTags manually.
|
Enumerations
| TableType |
The PangoOTTableType enumeration values are used to
identify the various OpenType tables in the
pango_ot_info_… functions.
|
Functions
| tag_from_language |
Finds the OpenType language-system tag best describing language.
since: 1.18
|
| tag_from_script |
Finds the OpenType script tag corresponding to script.
since: 1.18
|
| tag_to_language |
Finds a PangoLanguage corresponding to language_tag.
since: 1.18
|
| tag_to_script |
Finds the PangoScript corresponding to script_tag.
since: 1.18
|
Function Macros
| TAG_MAKE |
Creates a PangoOTTag from four characters. This is similar and
compatible with the FT_MAKE_TAG() macro from FreeType.
|
| TAG_MAKE_FROM_STRING |
Creates a PangoOTTag from a string. The string should be at least
four characters long (pad with space characters if needed), and need
not be nul-terminated. This is a convenience wrapper around
PANGO_OT_TAG_MAKE(), but cannot be used in certain situations, for
example, as a switch expression, as it dereferences pointers.
|
Constants
| ALL_GLYPHS |
This is used as the property bit in pango_ot_ruleset_add_feature() when a
feature should be applied to all glyphs.
|
| DEFAULT_LANGUAGE |
This is used as the language index in pango_ot_info_find_feature() when
the default language system of the script is desired.
|
| NO_FEATURE |
This is used as a feature index that represent no feature, that is, should be
skipped. It may be returned as feature index by pango_ot_info_find_feature()
if the feature is not found, and pango_ot_ruleset_add_feature() function
automatically skips this value, so no special handling is required by the user.
|
| NO_SCRIPT |
This is used as a script index that represent no script, that is, when the
requested script was not found, and a default (‘DFLT’) script was not found
either. It may be returned as script index by pango_ot_info_find_script()
if the script or a default script are not found, all other functions
taking a script index essentially return if the input script index is
this value, so no special handling is required by the user.
