CHANGES BETWEEN 2.8.1 and 2.8.2 |
|
|
|
|
|
|
|
|
|
I. IMPORTANT BUG FIXES |
|
|
|
|
|
|
|
|
|
- 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. |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
II. IMPORTANT CHANGES |
|
|
|
|
|
|
|
|
|
- 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). |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
III. MISCELLANEOUS |
|
|
|
|
|
|
|
|
|
- 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. |
|
|
|
|
|
|
|
|
|
- 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. |
|
|
