Functions for fetching various bit fields and numbers scattered around OpenType tables.

These are raw table values, and many of them are legacy or unreliable, but applications might need them for various legacy reasons.

uint32_t
hb_ot_fetch_bits (hb_face_t *face,
                  hb_ot_bits_tag_t tag);

Fetches a bit field of face .

face	hb_face_t to work upon
tag	tag of the bit field to fetch

the bit field, or zero if the font does not have it.

Since: 14.3.0

int32_t
hb_ot_fetch_number (hb_face_t *face,
                    hb_ot_number_tag_t tag);

Fetches a number of face in font units.

face	hb_face_t to work upon
tag	tag of the number to fetch

the number, or zero if the font does not have it.
