Struct

PangoOTRulesetDescription

Description [src]

struct PangoOTRulesetDescription {
  PangoScript script;
  PangoLanguage* language;
  const PangoOTFeatureMap* static_gsub_features;
  guint n_static_gsub_features;
  const PangoOTFeatureMap* static_gpos_features;
  guint n_static_gpos_features;
  const PangoOTFeatureMap* other_features;
  guint n_other_features;
}

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().
