CHANGES BETWEEN 2.8.1 and 2.9

  • Advance width values of variation fonts were often wrong.
  • More fixes for variation font support; you should update to this version if you want to support them.
  • As a GSoC project, Ewald Hew extended the new (Adobe) CFF engine to handle Type 1 fonts also, thus greatly improving the rendering of this format. This is the new default. The old engine is still available if the configuration macro `T1_CONFIG_OPTION_OLD_ENGINE' gets defined; using the hinting-engine' property of the type1' driver module you can then switch between the two engines.
  • A new function, `FT_Set_Named_Instance', can be used to set or change the current named instance.
  • Starting with this FreeType version, resetting variation coordinates will return to the currently selected named instance. Previously, FreeType returned to the base font (i.e., no instance set).
  • The face_flags' field of the FT_Face' structure has a new bit, `FT_FACE_FLAG_VARIATION', which is set if a variation font has been altered with `FT_Set_MM_Design_Coordinates', `FT_Set_Var_Design_Coordinates', or `FT_Set_Var_Blend_Coordinates'.
  • If the current face is a named instance, the new macro `FT_IS_NAMED_INSTANCE' returns true.
  • `FT_IS_VARIATION' is a new macro that returns true whenever a face object has been altered by `FT_Set_MM_Design_Coordinates', `FT_Set_Var_Design_Coordinates', or `FT_Set_Var_Blend_Coordinates'.
  • Changing the design coordinates of a variation font with `FT_Set_Var_Design_Coordinates' or `FT_Set_Var_Blend_Coordinates' does not influence the named instance index value (only `FT_Set_Named_Instance' does that).
  • Special PostScript names for named instances are only returned if the named instance is set with `FT_Set_Named_Instance' (and the font has corresponding entries in its `fvar' table). If `FT_IS_VARIATION' returns true, the algorithmically derived PostScript name is provided, not looking up special entries for named instances.
  • A new function `FT_Done_MM_Var' is provided to free the memory returned in a call to `FT_Get_MM_Var'.
  • On platforms using the `configure' script, the installed `ftoption.h' file now correctly reflects configuration options like `--with-harfbuzz'.
  • Better support to build FreeType as a DLL on Windows using Visual C.
  • All data specific to driver modules is now collected in a single file, `FT_DRIVER_H'. Consequently, the macros FT_AUTOHINTER_H', FT_CFF_DRIVER_H', `FT_TRUETYPE_DRIVER_H', and `FT_PCF_DRIVER_H' still work but are deprecated.
  • Some fuzzer fixes to better reject malformed fonts.
  • The `ftbench' demo program has a new test for opening a new face and loading some glyphs.
  • The ftbench' demo program has a new option -j' to specify the last glyph index to be used in the tests.
  • The ftgrid' demo program has a new option -n' to suppress display of named instances of variation fonts.
  • The ttdebug' demo program can now show a stack trace (key K') and switch between hexadecimal and decimal display of integers (key `I').
