harfbuzz: Update to version 8.0.1
- Update from version 7.3.0 to 8.0.1
- Update of rootfile
- Changelog
Overview of changes leading to 8.0.1
- Build fix on 32-bit arm.
- More speed optimizations:
- 60% speedup in retaingids subsetting SourceHanSans-VF.
- 38% speed up in subsetting (beyond-64k) mega-merged Noto.
- 16% speed up in retain-gid (used for IFT) subsetting of NotoSansCJKkr.
Overview of changes leading to 8.0.0
- New, experimental, WebAssembly (WASM) shaper, that provides greater
flexibility over OpenType/AAT/Graphite shaping, using WebAssembly embedded
inside the font file. Currently WASM shaper is disabled by default and needs
to be enabled at build time. For details, see:
https://github.com/harfbuzz/harfbuzz/blob/main/docs/wasm-shaper.md
For example fonts making use of the WASM shaper, see:
https://github.com/simoncozens/wasm-examples
- Improvements to Experimental features introduced in earlier releases:
- Support for subsetting beyond-64k and VarComposites fonts.
- Support for instancing variable fonts with cubic “glyf” table.
- Many big speed optimizations:
- Up to 89% speedup loading variable fonts for shaping.
- Up to 88% speedup in small subsets of large (eg. CJK) fonts (both TTF and
OTF), essential for Incremental Font Transfer (IFT).
- Over 50% speedup in loading Roboto font for shaping.
- Up to 40% speed up in loading (sanitizing) complex fonts.
- 30% speed up in shaping Gulzar font.
- Over 25% speedup in glyph loading Roboto font.
- 10% speed up loading glyph shapes in VarComposite Hangul font.
- hb-hashmap optimizations & hashing improvements.
- New macro HB_ALWAYS_INLINE. HarfBuzz now inlines functions more aggressively,
which results in some speedup at the expense of bigger code size. To disable
this feature define the macro to just inline.
- New API:
+HB_CODEPOINT_INVALID
+hb_ot_layout_get_baseline2()
+hb_ot_layout_get_baseline_with_fallback2()
+hb_ot_layout_get_font_extents()
+hb_ot_layout_get_font_extents2()
+hb_subset_input_set_axis_range()

harfbuzz: Update to version 6.0.0
- Update from version 4.4.1 to 6.0.0
- Update of rootfile
- Changelog
Overview of changes leading to 6.0.0
- A new API have been added to pre-process the face and speed up future
subsetting operations on that face. Provides up to a 95% reduction in
subsetting times when the same face is subset more than once.
For more details and benchmarks, see:
https://github.com/harfbuzz/harfbuzz/blob/main/docs/subset-preprocessing.md
- Shaping have been speedup by skipping entire lookups when the buffer contents
don't intersect with the lookup. Shows up to a 10% speedup in shaping some
fonts. (Behdad Esfahbod)
- A new experimental feature, “Variable Composites” (enabled by passing
-Dexperimental_api=true to meson), is also featured in this release.
This technology enables drastic compression of fonts in the Chinese,
Japanese, Korean, and other writing systems, by reusing the OpenType Font
Variations technology for encoding “smart components” into the font.
The specification for these extensions to the font format can be found in:
https://github.com/harfbuzz/boring-expansion-spec/blob/glyf1/glyf1.md
A test variable-font with ~7160 Hangul syllables derived from the
NotoSerifKR-VF font has been built, with existing OpenType technology, as
well as with the new Variable Composites (VarComposites) technology. The
VarComposites font is over 90% smaller than the OpenType version of the font!
Both fonts can be obtained from the “smarties” repository:
https://github.com/behdad/smarties/tree/3.0/fonts/hangul/serif
When building HarfBuzz with experimental features enabled, you can test
the “smarties” font with a sample character like this:
$ hb-view butchered-hangul-serif-smarties-variable.ttf -u AE01 --variations=wght=700
- The HarfBuzz subsetter can now drop axes by pinning them to specific values
(also referred to as instancing). There are a couple of restrictions
currently:
- Only works with TrueType (“glyf”) based fonts. “CFF2” fonts are not yet
supported.
- Only supports the case where all axes in a font are pinned.
- Miscellaneous fixes and improvements.
- New API
+hb_subset_input_pin_axis_location()
+hb_subset_input_pin_axis_to_default()
+hb_subset_preprocess()

- A new experimental hb_subset_repack_or_fail() to repack an array of objects,
eliminating offset overflows. The API is not available unless HarfBuzz is
built with experimental APIs enabled. (Qunxin Liu)
- New experimental API
+hb_link_t
+hb_object_t
+hb_subset_repack_or_fail()
Overview of changes leading to 4.0.0
Tuesday, March 1, 2022
- New public API to create subset plan and gather information on things like
glyph mappings in the final subset. The plan can then be passed on to perform
the subsetting operation. (Garret Rieger)
- Draw API for extracting glyph shapes have been extended and finalized and is
no longer an experimental API. The draw API supports glyf, CFF and CFF2
glyph outlines tables, and applies variation settings set on the font as well
as synthetic slant. The new public API is not backward compatible with the
previous, non-public, experimental API. (Behdad Esfahbod)
- The hb-view tool will use HarfBuzz draw API to render the glyphs instead of
cairo-ft when compiled with Cairo 1.17.5 or newer, setting HB_DRAW
environment variable to 1 or 0 will force using or not use the draw API,
respectively. (Behdad Esfahbod)
- The hb-shape and hb-view tools now default to using HarfBuzz’s own font
loading functions (ot) instead of FreeType ones (ft). They also have a new
option, --font-slant, to apply synthetic slant to the font. (Behdad Esfahbod)
- HarfBuzz now supports more than 65535 (the OpenType limit) glyph shapes and
metrics. See https://github.com/be-fonts/boring-expansion-spec/issues/6 and
https://github.com/be-fonts/boring-expansion-spec/issues/7 for details.
(Behdad Esfahbod)
- New API to get the dominant horizontal baseline tag for a given script.
(Behdad Esfahbod)
- New API to get the baseline positions from the font, and synthesize missing
ones. As well as new API to get font metrics and synthesize missing ones.
(Matthias Clasen)
- Improvements to finding dependencies on Windows when building with Visual
Studio. (Chun-wei Fan)
- New buffer flag, HB_BUFFER_FLAG_PRODUCE_UNSAFE_TO_CONCAT, that must be set

harfbuzz: Update to version 3.4.0
- Update from 3.1.2 to 3.4.0 - Update of rootfile - Changelog 3.4.0 Perform sanity checks on shaping results is now part of “harfbuzz” library and can be enabled by setting the buffer flag HB_BUFFER_FLAG_VERIFY. (Behdad Esfahbod) Arabic Mark Transient Reordering Algorithm have been updated to revision 6. (Khaled Hosny) ISO 15924 code for mathematical notation, ‘Zmth’, now maps to the OpenType ‘math’ tag. (Alexis King) It is now possible to get at once all math kerning values for a given glyph at a given corner. (Alexis King) Fix locale_t portability issues on systems the typedef’s it to a void pointer. (Behdad Esfahbod) New API: +HB_BUFFER_FLAG_VERIFY +HB_OT_TAG_MATH_SCRIPT +HB_SCRIPT_MATH +hb_ot_math_kern_entry_t +hb_ot_math_get_glyph_kernings Deprecated API +HB_OT_MATH_SCRIPT 3.3.2 Revert splitting of pair positioning values introduced in 3.3.0 as it proved problematic. (Behdad Esfahbod) 3.3.1 Fix heap-use-after-free in harfbuzz-subset introduced in previous release. (Garret Rieger) 3.3.0 Improved documentation. (Matthias Clasen) Internal code cleanup, using C++ standard library more. (Behdad Esfahbod) 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. (Behdad Esfahbod) Glyph positions and other font metrics now apply synthetic slant set by hb_font_set_synthetic_slant(), for improved positioning for synthetically slanted fonts. (Behdad Esfahbod) Fixed unintentional locale dependency in hb_variation_to_string() for decimal point representation. (Matthias Clasen) When applying pair positioning (kerning) the positioning value is split between the two sides of the pair for improved cursor positioning between such pairs. (Behdad Esfahbod) 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. (Behdad Esfahbod) Improved handling of macrolanguages when mapping BCP 47 codes to OpenType tags. (David Corbett) 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() 3.2.0 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) OpenType 1.9 language tags update. (David Corbett) Add HB_NO_VERTICAL config option. (Behdad Esfahbod) Add HB_CONFIG_OVERRIDE_H for easier configuration. (Behdad Esfahbod) harfbuzz-subset library improvements: Improved packing of cmap, loca, and Ligature tables. (Garret Rieger) Significantly improved overflow-resolution strategy in the repacker.
