-
Update to Unicode 10.
-
Various Indic and Universal Shaping Engine fixes as a result of
HarfBuzz Hackfest with Jonathan Kew at Web Engines Hackfest at
the Igalia offices in A Coruña, Spain. Thanks Igalia for having
us! -
Implement Unicode Arabic Mark Ordering Algorithm UTR#53.
-
Implement optical sizing / tracking in CoreText backend, using
new API hb_font_set_ptem(). -
Allow notifying hb_font_t that underlying FT_Face changed sizing,
using new API hb_ft_font_changed(). -
More Graphite backend RTL fixes.
-
Fix caching of variable font shaping plans.
-
hb-view / hb-shape now accept following new arguments:
o --unicodes: takes a list of hex numbers that represent Unicode
codepoints.
New API:
+hb_face_get_table_tags()
+hb_font_set_ptem()
+hb_font_get_ptem()
+hb_ft_font_changed()
1.5.1
Overview of changes leading to 1.5.1
Tuesday, September 5, 2017
- Fix "unsafe-to-break" in fallback shaping and other corner cases.
All our tests pass with --verify now, meaning unsafe-to-break API
works as expected. - Add --unicodes to hb-view / hb-shape.
- [indic] Treat Consonant_With_Stacker as consonant. This will need
further tweaking. - hb_buffer_diff() tweaks.
1.5.0
Overview of changes leading to 1.5.0
Wednesday, August 23, 2017
-
Misc new API, for appending a buffer to another, and for comparing
contents of two buffers for types of differences. -
New "unsafe-to-break" API. Can be used to speed up reshaping
in line-breaking situations. Essentially, after shaping, it returns
positions in the input string (some of the cluster boundaries) that
are "safe to break" in that if the text is segmented at that position
and two sides reshaped and concatenated, the shaping result is
exactly the same as shaping the text in one piece.hb-view and hb-shape and hb-shape now take --verify, which verifies
the above property.Some corner cases of the implementation are still not quite working.
Those will be fixed in subsequent releases. -
New API:
hb_buffer_append()
hb_glyph_flags_t
HB_GLYPH_FLAG_UNSAFE_TO_BREAK
HB_GLYPH_FLAG_DEFINED
hb_glyph_info_get_glyph_flags()
HB_BUFFER_SERIALIZE_FLAG_GLYPH_FLAGS
hb_buffer_diff_flags_t
HB_BUFFER_DIFF_FLAG_EQUAL
HB_BUFFER_DIFF_FLAG_CONTENT_TYPE_MISMATCH
HB_BUFFER_DIFF_FLAG_LENGTH_MISMATCH
HB_BUFFER_DIFF_FLAG_NOTDEF_PRESENT
HB_BUFFER_DIFF_FLAG_DOTTED_CIRCLE_PRESENT
HB_BUFFER_DIFF_FLAG_CODEPOINT_MISMATCH
HB_BUFFER_DIFF_FLAG_CLUSTER_MISMATCH
HB_BUFFER_DIFF_FLAG_GLYPH_FLAGS_MISMATCH
HB_BUFFER_DIFF_FLAG_POSITION_MISMATCH
hb_buffer_diff
