Functions

hb_font_get_glyph_func_t ()

hb_bool_t
(*hb_font_get_glyph_func_t) (hb_font_t *font,
                             void *font_data,
                             hb_codepoint_t unicode,
                             hb_codepoint_t variation_selector,

                             void *user_data);

hb_font_get_glyph_func_t is deprecated and should not be used in newly-written code.

hb_ot_layout_table_find_script ()

hb_bool_t
hb_ot_layout_table_find_script (hb_face_t *face,
                                hb_tag_t table_tag,
                                hb_tag_t script_tag,
                                unsigned int *script_index);

Fetches the index if a given script tag in the specified face's GSUB table or GPOS table.

Parameters

face	hb_face_t to work upon
table_tag	HB_OT_TAG_GSUB or HB_OT_TAG_GPOS
script_tag	hb_tag_t of the script tag requested
script_index	The index of the requested script tag.	[out]

Returns

true if the script is found, false otherwise
