HB_OT_TAG_MATH:
OpenType Mathematical Typesetting Table.
Since: 1.3.3
Definition at line 50 of file hb-ot-math.h.
HB_OT_TAG_MATH_SCRIPT:
OpenType script tag, math, for features specific to math shaping.
<note>HB_OT_TAG_MATH_SCRIPT is not a valid hb_script_t and should only be used with functions that accept raw OpenType script tags, such as hb_ot_layout_collect_features. In other cases, HB_SCRIPT_MATH should be used instead.</note>

| typedef struct hb_ot_math_glyph_part_t hb_ot_math_glyph_part_t |
hb_ot_math_glyph_part_t: @glyph: The glyph index of the variant part @start_connector_length: The length of the connector on the starting side of the variant part @end_connector_length: The length of the connector on the ending side of the variant part @full_advance: The total advance of the part @flags: hb_ot_math_glyph_part_flags_t flags for the part
Data type to hold information for a "part" component of a math-variant glyph. Large variants for stretchable math glyphs (such as parentheses) can be constructed on the fly from parts.
