Unimplemented callbacks in the - subclass automatically chainup to the parent. When chaining up, - scale is adjusted if the parent font has a different scale. - - o All hb_font_funcs_t callbacks take a user_data now. Their setters - take a user_data and its respective destroy callback. - - o New API: - hb_font_get_parent() - hb_font_funcs_get_empty() - hb_font_create_sub_font() - - o Removed API: - hb_font_funcs_copy() - hb_font_unset_funcs() - - o Removed func getter functions: - hb_font_funcs_get_glyph_func() - hb_font_funcs_get_glyph_advance_func() - hb_font_funcs_get_glyph_extents_func() - hb_font_funcs_get_contour_point_func() - hb_font_funcs_get_kerning_func() - - o Changed API: - hb_font_create() takes a face and references it now - hb_font_set_funcs() takes user_data before destroy now - hb_font_set_scale() accepts signed integers now - hb_font_get_contour_point_func_t now takes glyph first, then point_index - hb_font_get_glyph_func_t returns a success boolean now - - -* Changed object model: - - o All object types have a _get_empty() now: - hb_blob_get_empty() - hb_buffer_get_empty() - hb_face_get_empty() - hb_font_get_empty() - hb_font_funcs_get_empty() - hb_unicode_funcs_get_empty() - - o Added _set_user_data() and _get_user_data() for all object types: - hb_blob_get_user_data() - hb_blob_set_user_data() - hb_buffer_get_user_data() - hb_buffer_set_user_data() - hb_face_get_user_data() - hb_face_set_user_data() - hb_font_funcs_get_user_data() - hb_font_funcs_set_user_data() - hb_font_get_user_data() - hb_font_set_user_data() - hb_unicode_funcs_get_user_data() - hb_unicode_funcs_set_user_data() - - o Removed the _get_reference_count() from all object types: - hb_blob_get_reference_count() - hb_buffer_get_reference_count() - hb_face_get_reference_count() - hb_font_funcs_get_reference_count() - hb_font_get_reference_count() - hb_unicode_funcs_get_reference_count() - - o Added _make_immutable() and _is_immutable() for all object types except for buffer: - hb_blob_make_immutable() - hb_blob_is_immutable() - hb_face_make_immutable() - hb_face_is_immutable() - - -* Changed API for vertical text support - - o The following callbacks where removed: - hb_font_get_glyph_advance_func_t - hb_font_get_kerning_func_t - - o The following new callbacks added instead: - hb_font_get_glyph_h_advance_func_t - hb_font_get_glyph_v_advance_func_t - hb_font_get_glyph_h_origin_func_t - hb_font_get_glyph_v_origin_func_t - hb_font_get_glyph_h_kerning_func_t - hb_font_get_glyph_v_kerning_func_t - - o The following API removed as such: - hb_font_funcs_set_glyph_advance_func() - hb_font_funcs_set_kerning_func() - hb_font_get_glyph_advance() - hb_font_get_kerning() - - o New API added instead: - hb_font_funcs_set_glyph_h_advance_func() - hb_font_funcs_set_glyph_v_advance_func() - hb_font_funcs_set_glyph_h_origin_func() - hb_font_funcs_set_glyph_v_origin_func() - hb_font_funcs_set_glyph_h_kerning_func() - hb_font_funcs_set_glyph_v_kerning_func() - hb_font_get_glyph_h_advance() - hb_font_get_glyph_v_advance() - hb_font_get_glyph_h_origin() - hb_font_get_glyph_v_origin() - hb_font_get_glyph_h_kerning() - hb_font_get_glyph_v_kerning() - - o The following higher-leve API added for convenience: - hb_font_get_glyph_advance_for_direction() - hb_font_get_glyph_origin_for_direction() - hb_font_add_glyph_origin_for_direction() - hb_font_subtract_glyph_origin_for_direction() - hb_font_get_glyph_kerning_for_direction() - hb_font_get_glyph_extents_for_origin() - hb_font_get_glyph_contour_point_for_origin() - - -* OpenType Layout API: - - o New API: - hb_ot_layout_position_start() - hb_ot_layout_substitute_start() - hb_ot_layout_substitute_finish() - - -* Glue code: - - o New API: - hb_glib_script_to_script() - hb_glib_script_from_script() - hb_icu_script_to_script() - hb_icu_script_from_script() - - -* Version API added: - - o New API: - HB_VERSION_MAJOR - HB_VERSION_MINOR - HB_VERSION_MICRO - HB_VERSION_STRING - HB_VERSION_CHECK() - hb_version() - hb_version_string() - hb_version_check() - - |
