Overview of changes leading to 3.3.0
|
||||
Monday, January 31, 2022
|
||||
====================================
|
||||
- Improved documentation.
|
||||
- Internal code cleanup, using C++ standard library more.
|
||||
- The low 16-bits of face index will be used by hb_face_create() to select a
|
||||
face inside a font collection file format, while the high 16-bits will be
|
||||
used by hb_font_create() to load the named instance.
|
||||
- Glyph positions and other font metrics now apply synthetic slant set by
|
||||
hb_font_set_synthetic_slant(), for improved positioning for synthetically
|
||||
slanted fonts.
|
||||
- Fixed unintentional locale dependency in hb_variation_to_string() for decimal
|
||||
point representation.
|
||||
- When applying pair positioning (kerning) the positioning value is split
|
||||
between the two sides of the pair for improved cursor positioning between
|
||||
such pairs.
|
||||
- Introduced new HB_GLYPH_FLAG_UNSAFE_TO_CONCAT, to be used in conjunction
|
||||
with HB_GLYPH_FLAG_UNSAFE_TO_BREAK for optimizing re-shaping during line
|
||||
breaking. Check the documentation for further details.
|
||||
- Improved handling of macrolanguages when mapping BCP 47 codes to OpenType
|
||||
tags.
|
||||
|
||||
- New API:
|
||||
+HB_GLYPH_FLAG_UNSAFE_TO_CONCAT
|
||||
+hb_segment_properties_overlay()
|
||||
+hb_buffer_create_similar()
|
||||
+hb_font_set_synthetic_slant()
|
||||
+hb_font_get_synthetic_slant()
|
||||
+hb_font_get_var_coords_design()

|
||||
====================================
|
||||
|
||||
“harfbuzz” library improvements:
|
||||
- Fixed shaping of Apple Color Emoji flags in right-to-left context. (Behdad Esfahbod)
|
||||
- Fixed positioning of CFF fonts in HB_TINY profile. (Behdad Esfahbod)
