Special notes to Unix users
===========================
Please read the file `docs/UPGRADE.UNIX'. It contains important
information regarding the installation of FreeType on Unix systems,
especially GNU based operating systems like GNU/Linux.
FreeType 2's library is called `libfreetype', FreeType 1's library
is called `libttf'. They are *not* compatible!
FreeType 2.3.5
==============
Please read the docs/CHANGES file, it contains IMPORTANT
INFORMATION.
Read the files `docs/INSTALL' for installation instructions.
The FreeType 2 API reference is located in `docs/reference'; use the
file `ft2-doc.html' as the top entry point. Additional
documentation is available as a separate package from our sites. Go
to
http://download.savannah.gnu.org/releases/freetype/
and download one of the following files.
freetype-doc-2.3.5.tar.bz2
freetype-doc-2.3.5.tar.gz
ftdoc235.zip
Bugs
====
Please report bugs by e-mail to `freetype-devel@nongnu.org'. Don't
forget to send a detailed explanation of the problem -- there is
nothing worse than receiving a terse message that only says `it
doesn't work'.
Alternatively, you may submit a bug report at
https://savannah.nongnu.org/bugs/?group=freetype
Enjoy!

The CVS archive doesn't contain pre-built configuration scripts for
UNIXish platforms. To generate them say
sh autogen.sh
which in turn depends on the following packages:
automake (1.9.6)
libtool (1.5.22)
autoconf (2.59c)
The versions given in parentheses are known to work. Newer versions
should work too, of course. Note that autogen.sh also sets up proper
file permissions for the `configure' and auxiliary scripts.
A very common problem is that this script complains that the `aclocal'
program doesn't accept a `--force' option:
generating `configure.ac'
running `aclocal -I . --force'
aclocal: unrecognized option -- `--force'
Try `aclocal --help' for more information.
error while running `aclocal -I . --force'
This means that your version of the automake package is too old.
Please update it before trying to build FreeType.
For static builds which don't use platform specific optimizations, no
configure script is necessary at all; saying
make setup ansi
make
should work on all platforms which have GNU make (or makepp).

CREDITS
The code in this tree is based (it is actually an exact copy with some
ReactOS specific extra files) on the FreeType library, version 2.3.0
It was written and is being maintained by the FreeType team. The projects
website is http://www.freetype.org.
NOTES
Please note that there are two Makefiles in the freetype directory:
- Makefile.freetype which is the original Makefile from the FreeType
distribution
- Makefile which is the ReactOS specific Makefile. It will use the
original Makefile.freetype when needed.
Normally you will just use Makefile and not worry about Makefile.freetype.
There will also be 2 FreeType libraries, lib/freetype/objs/libfreetype.a
and dk/nkm/lib/freetype.a. The second one is the import library for
freetype.dll and is the one that is used in the rest of ReactOS.
lib/freetype/objs/libfreetype.a is a static library which is used to
create the DLL.
PORTING A NEW VERSION
Please note that the procedure below is a one-time only procedure, to be
performed by whoever imports a new FreeType version into the ReactOS
source tree. Once the new version has been committed to CVS all other
developers can just use the normal build procedure.
First, save the old version:
move lib\freetype lib\freetype.old
Unpack the FreeType distribution and copy the files to lib/freetype
(note: without the version number which is present in the pathnames in
the distribution archive).
Setup the FreeType build by copying the correct configuration file:
copy lib\freetype\builds\win32\w32-mingw32.mk lib\freetype\config.mk
Copy the ReactOS specific files from the old directory to the new:
move lib\freetype\Makefile lib\freetype\Makefile.freetype
mkdir lib\freetype\i386
copy lib\freetype.old\rosglue.c lib\freetype
copy lib\freetype.old\i386\setjmplongjmp.s lib\freetype\i386
copy lib\freetype.old\freetype.rc lib\freetype
copy lib\freetype.old\Makefile lib\freetype
copy lib\freetype.old\README.ROS lib\freetype
copy lib\freetype.old\Doxyfile lib\freetype
copy lib\freetype.old\.cvsignore lib\freetype
copy lib\freetype.old\objs\.cvsignore lib\freetype\objs
copy lib\freetype.old\i386\.cvsignore lib\freetype\i386
Next you need to create the freetype.def file. Since this depends on the
"gawk" command, you'll need to have MSYS installed, which is not one of
the normally required packages to build ReactOS. You can get MSYS from the
MinGW site at http://sourceforge.net/projects/mingw. Once you have MSYS
installed you can create the new freetype.def file:
make freetype_def
Well, that's all there is to it. You can delete the old version in
lib\freetype.old. Please adjust the version number in the heading of this
file, so it is obvious to everyone which FreeType version we're using.
After testing, you can commit the new/changed files to CVS. ALthough files
config.mk and freetype.def are generated, they should be included in CVS.

/* USER-SELECTABLE CONFIGURATION MACROS */
/* */
/* This file contains the default configuration macro definitions for */
/* a standard build of the FreeType library. There are three ways to */
/* use this file to build project-specific versions of the library: */
/* */
/* - You can modify this file by hand, but this is not recommended in */
/* cases where you would like to build several versions of the */
/* library from a single source directory. */
/* */
/* - You can put a copy of this file in your build directory, more */
/* precisely in `$BUILD/freetype/config/ftoption.h', where `$BUILD' */
/* is the name of a directory that is included _before_ the FreeType */
/* include path during compilation. */
/* */
/* The default FreeType Makefiles and Jamfiles use the build */
/* directory `builds/<system>' by default, but you can easily change */
/* that for your own projects. */
/* */
/* - Copy the file <ft2build.h> to `$BUILD/ft2build.h' and modify it */
/* slightly to pre-define the macro FT_CONFIG_OPTIONS_H used to */
/* locate this file during the build. For example, */
/* */
/* #define FT_CONFIG_OPTIONS_H <myftoptions.h> */
/* #include <freetype/config/ftheader.h> */
/* */
/* will use `$BUILD/myftoptions.h' instead of this file for macro */
/* definitions. */
/* */
/* Note also that you can similarly pre-define the macro */
/* FT_CONFIG_MODULES_H used to locate the file listing of the modules */
/* that are statically linked to the library at compile time. By */
/* default, this file is <freetype/config/ftmodule.h>. */
/* */
/* We highly recommend using the third method whenever possible. */

/* This special header file is used to define the handling of FT2 */
/* enumeration constants. It can also be used to generate error message */
/* strings with a small macro trick explained below. */
/* */
/* I - Error Formats */
/* ----------------- */
/* */
/* The configuration macro FT_CONFIG_OPTION_USE_MODULE_ERRORS can be */
/* defined in ftoption.h in order to make the higher byte indicate */
/* the module where the error has happened (this is not compatible */
/* with standard builds of FreeType 2). You can then use the macro */
/* FT_ERROR_BASE macro to extract the generic error code from an */
/* FT_Error value. */
/* */
/* */
/* II - Error Message strings */
/* -------------------------- */
/* */
/* The error definitions below are made through special macros that */
/* allow client applications to build a table of error message strings */
/* if they need it. The strings are not included in a normal build of */
/* FreeType 2 to save space (most client applications do not use */
/* them). */
/* */
/* To do so, you have to define the following macros before including */
/* this file: */
/* */
/* FT_ERROR_START_LIST :: */
/* This macro is called before anything else to define the start of */
/* the error list. It is followed by several FT_ERROR_DEF calls */
/* (see below). */
/* */
/* FT_ERROR_DEF( e, v, s ) :: */
/* This macro is called to define one single error. */
/* `e' is the error code identifier (e.g. FT_Err_Invalid_Argument). */
/* `v' is the error numerical value. */
/* `s' is the corresponding error string. */
/* */
/* FT_ERROR_END_LIST :: */
/* This macro ends the list. */
/* */
/* Additionally, you have to undefine __FTERRORS_H__ before #including */
/* this file. */
/* */
/* Here is a simple example: */
/* */
/* { */
/* #undef __FTERRORS_H__ */

* Calling the internal function `FT_Stream_Close' on the new stream will
* *not* call `FT_Stream_Close' on the source stream. None of the stream
* objects will be released to the heap.
*
* The stream implementation is very basic and resets the decompression
* process each time seeking backwards is needed within the stream
*
* In certain builds of the library, LZW compression recognition is
* automatically handled when calling @FT_New_Face or @FT_Open_Face.
* This means that if no font driver is capable of handling the raw
* compressed file, the library will try to open a LZW stream from it
* and re-open the face with it.

* encodings (except for cp1361) can be found at ftp://ftp.unicode.org
* in the MAPPINGS/VENDORS/MICSFT/WINDOWS subdirectory. cp1361 is
* roughly a superset of MAPPINGS/OBSOLETE/EASTASIA/KSC/JOHAB.TXT.
*
* @values:
* FT_WinFNT_ID_DEFAULT ::
* This is used for font enumeration and font creation as a
* `don't care' value. Valid font files don't contain this value.
* When querying for information about the character set of the font
* that is currently selected into a specified device context, this
* return value (of the related Windows API) simply denotes failure.
*
* FT_WinFNT_ID_SYMBOL ::
* There is no known mapping table available.
*
* FT_WinFNT_ID_MAC ::
* Mac Roman encoding.
*
* FT_WinFNT_ID_OEM ::
* From Michael Pöttgen <michael@poettgen.de>:
*
* The `Windows Font Mapping' article says that FT_WinFNT_ID_OEM
* is used for the charset of vector fonts, like `modern.fon',
* `roman.fon', and `script.fon' on Windows.
*
* The `CreateFont' documentation says: The FT_WinFNT_ID_OEM value
* specifies a character set that is operating-system dependent.
*
* The `IFIMETRICS' documentation from the `Windows Driver
* Development Kit' says: This font supports an OEM-specific
* character set. The OEM character set is system dependent.
*
* In general OEM, as opposed to ANSI (i.e., cp1252), denotes the
* second default codepage that most international versions of
* Windows have. It is one of the OEM codepages from
*
* http://www.microsoft.com/globaldev/reference/cphome.mspx,
*
* and is used for the `DOS boxes', to support legacy applications.
* A German Windows version for example usually uses ANSI codepage
* 1252 and OEM codepage 850.
*
* FT_WinFNT_ID_CP874 ::
* A superset of Thai TIS 620 and ISO 8859-11.
*
* FT_WinFNT_ID_CP932 ::
* A superset of Japanese Shift-JIS (with minor deviations).
*
* FT_WinFNT_ID_CP936 ::
* A superset of simplified Chinese GB 2312-1980 (with different
* ordering and minor deviations).
*
* FT_WinFNT_ID_CP949 ::
* A superset of Korean Hangul KS C 5601-1987 (with different
* ordering and minor deviations).
*
* FT_WinFNT_ID_CP950 ::
* A superset of traditional Chinese Big 5 ETen (with different

*
* FT_WinFNT_ID_CP1250 ::
* A superset of East European ISO 8859-2 (with slightly different

* FT_WinFNT_ID_CP1251 ::

/* */
/* A small technical note regarding automatic hinting in order to */
/* clarify this module interface. */
/* */
/* An automatic hinter might compute two kinds of data for a given face: */
/* */
/* - global hints: Usually some metrics that describe global properties */
/* of the face. It is computed by scanning more or less */
/* aggressively the glyphs in the face, and thus can be */
/* very slow to compute (even if the size of global */
/* hints is really small). */
/* */
/* - glyph hints: These describe some important features of the glyph */
/* outline, as well as how to align them. They are */
/* generally much faster to compute than global hints. */
/* */
/* The current FreeType auto-hinter does a pretty good job while */
/* performing fast computations for both global and glyph hints. */
/* However, we might be interested in introducing more complex and */
/* powerful algorithms in the future, like the one described in the John */
/* D. Hobby paper, which unfortunately requires a lot more horsepower. */
/* */
/* Because a sufficiently sophisticated font management system would */
/* typically implement an LRU cache of opened face objects to reduce */
/* memory usage, it is a good idea to be able to avoid recomputing */
/* global hints every time the same face is re-opened. */
/* */
/* We thus provide the ability to cache global hints outside of the face */
/* object, in order to speed up font re-opening time. Of course, this */
/* feature is purely optional, so most client programs won't even notice */
/* it. */
/* */
/* I initially thought that it would be a good idea to cache the glyph */
/* hints too. However, my general idea now is that if you really need */
/* to cache these too, you are simply in need of a new font format, */
/* where all this information could be stored within the font file and */
/* decoded on the fly. */
