8.3.1

1 month ago

What's Changed

  • hb_blob_create_from_file_or_fail() on Windows will now try to interpret the file name as UTF-8 first, and as system code page if it is not valid UTF-8.
  • Fix hb_style_get_value() in fonts with “STAT” table.
  • Properly handle negative offsets in CFF table.
  • Update IANA Language Subtag Registry to 2024-03-07.
  • Subsetter now supports subsetting “BASE” table.
  • Subsetter will update “hhea” font metrics in sync with “OS/2” ones.
  • “--variations” option of “hb-subset” now supports leaving out values that should be unchanged, e.g. “wght=:500:” will change the default and keep max and min unchanged. It also supports “*=drop” to to pin all axes to default location.
  • Fix hb_ot_math_get_glyph_kerning() to match updated “MATH” table spec.
  • Support legacy MacRoman encoding in “cmap” table.
  • Various build fixes.
  • Various subsetting and instancing fixes.

8.0.0

9 months ago

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:

    https://github.com/harfbuzz/harfbuzz-wasm-examples

  • Improvements to Experimental features introduced in earlier releases:

  • 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()
