II. IMPORTANT CHANGES |
|
|
|
|
|
|
|
|
|
- version 2.2 does not expose its internals anymore, i.e. the content |
|
|
|
|
of 'include/freetype/internal' is not copied anymore by the |
|
|
|
|
'make install' command. This means that this will *break* source |
|
|
|
|
compatibility for a number of rogue clients that used to directly |
|
|
|
|
access freetype internal functions and/or structures. |
|
|
|
|
|
|
|
|
|
we provide patches for most rogue clients. See the following page |
|
|
|
|
for more information: |

|
Note that, as a convenience to our Unix desktop users, 2.2 is |
|
|
|
|
*binary* compatibly with FreeType 2.1.7, which means that installing |
|
|
|
|
this release on an existing distribution shall not break any working |

|
desktop. |

- FreeType's build mechanism has been redesigned. With GNU make |
|
|
|
|
it is now sufficient in most cases to edit two files: |
|

`modules.cfg', to select the library components, and the |

always forces auto-hinting, as a special exception. |

|
|
|
|
|
- A new API `FT_TrueTypeGX_Validate' (in FT_GX_VALIDATE_H) has |
|
|
|
|
been added to validate TrueType GX/ATT tables (feat, mort, morx, |
|
|
|
|
bsln, just, kern, opbd, trak, prop). After validation it is no |

|
longer necessary to check for errors in those tables while |

accessing them. This code has been contributed by Masatake |

- A new face flag `FT_FACE_FLAG_HINTER' has been added which is |
|

set if the font's driver has a hinting engine of its own. This |
