What's Changed
-
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:
-
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()
