Class
PangoOT.Info
Instance methods
pango_ot_info_find_feature
Finds the index of a feature. If the feature is not found, sets
feature_index
to PANGO_OT_NO_FEATURE, which is safe to pass to
pango_ot_ruleset_add_feature()
and similar functions.
pango_ot_info_find_language
Finds the index of a language and its required feature index.
If the language is not found, sets language_index
to
PANGO_OT_DEFAULT_LANGUAGE and the required feature of the default language
system is returned in required_feature_index. For best compatibility with
some fonts, also searches the language system tag ‘dflt’ before falling
back to the default language system, but that is transparent to the user.
The user can simply ignore the return value of this function to
automatically fall back to the default language system.
pango_ot_info_find_script
Finds the index of a script. If not found, tries to find the ‘DFLT’
and then ‘dflt’ scripts and return the index of that in script_index
.
If none of those is found either, PANGO_OT_NO_SCRIPT
is placed in
script_index
.
pango_ot_info_list_features
Obtains the list of features for the given language of the given script.
pango_ot_info_list_languages
Obtains the list of available languages for a given script.
pango_ot_info_list_scripts

Functions
