III. Bug descriptions
=====================
--- START OF OPEN BUGS ---
NO-CID-CMAPS
Not exactly a bug, but the CFF font driver doesn't build a Unicode charmap
from the contents of font files, which prevents efficiently using fonts in
this format.
BAD-TT-RENDERING
According to Paul Pedriana <PPedriana@maxis.com>, there is a rather
important difference between the rendering of TrueType-hinted glyphs of
current FT2 and old betas.
Tests and comparisons show a _major_ discrepancy of monochrome truetype
bytecode-hinted glyphs! Something seems to be really broken here!
Some of this has been fixed in 2.0.6; there was a bug in the TrueType
loader that prevented it from loading composites correctly. However,
there are still _subtle_ differences between FT1 and FT2 when it comes to
monochrome TrueType-hinted glyphs (the major differences are gone though).
BAD-THIN-LINES
It seems that the anti-aliased renderer in FreeType has problems rendering
extremely thin straight lines correctly, at least when using the
FT_Outline_Render() function.
NOT-WINDOWS-METRICS
FreeType doesn't always return the same metrics as Windows for ascender,
descender, and text height, depending on character pixel sizes. A lot of
testing on Windows is needed to debug this properly. It might be due to a
rounding bug when computing the "x_scale" and "y_scale" values.
ADVANCED-COMPOSITES
Provided by George Williams <pfaedit@users.sourceforge.net>:
I notice that truetype/ttgload.c only supports Apple's definition of
offsets for composite glyphs. Apple and Microsoft behave differently if
there is a scale factor. OpenType defines some bits to disambiguate.
(A problem in both 2.0.4 and 2.0.5.)
Apple says (http://fonts.apple.com/TTRefMan/RM06/Chap6glyf.html) that if
flags&ARGS_ARE_XY is set then the offsets should be scaled by the scale
factors (as you have done), but they also say something very cryptic
about what happens when the component is rotated at 45° (which you do
not support) -- See the "Important" note at the bottom.
The old truetype spec from Microsoft did not mention this. The OpenType
spec (http://www.microsoft.com/typography/otspec/glyf.htm,
http://partners.adobe.com/asn/developer/opentype/glyf.html) defines two
new bits to disambiguate:
SCALED_COMPONENT_OFFSET 11
Composite designed to have the component offset scaled (designed for
Apple rasterizer)
UNSCALED_COMPONENT_OFFSET 12
Composite designed not to have the component offset scaled (designed
for the Microsoft TrueType rasterizer)
Perhaps you could add a load_flag to allow the user to define the
default setting?
David says:
Wow, I was not even aware of this, it will probably take a little time
to implement since I don't have any font that implement these
"features", and also because I believe that we're running out of bits
for "load_flag", some other way to set preferences is probably needed.
--- END OF OPEN BUGS ---
BAD-TTNAMEID.H
The file "ttnameid.h" contains various constant macro definitions
corresponding to important values defined by the TrueType specification.
Joe Man <trmetal@yahoo.com.hk> reports that:
According to the information from TrueType v1.66:
Platform ID = 3 (Microsoft)
the Encoding ID of GB2312 = 4
the Encoding ID of big5 = 3
However, I have found that in ttnameid.h:
TT_MS_ID_GB2312 = 3
TT_MS_ID_BIG_5 = 4
Which one is correct?
Antoine replied that this was a bug in the TT 1.66 specification, and that
FreeType followed the most recent TrueType/OpenType specification here.
AUTOHINT-SBITS
When trying to load a glyph, with the auto-hinter activated (i.e., when
using FT_LOAD_FORCE_AUTOHINT, or when the font driver doesn't provide its
own hinter), embedded bitmaps are _never_ loaded, unlike the default
behaviour described by the API specification.
This seems to be a bug in FT_Load_Glyph(), but there is no way to solve it
efficiently without making a few important internal changes to the
library's design (more importantly, to the font driver interface).
This has been corrected with a hack in FT_Load_Glyph(). More important
internal changes should help get rid of it with a clean solution in a
further release like FreeType 2.1.
BAD-T1-CHARMAP
Type1 driver doesn't read "cacute" and "lslash" characters from iso8859-2
charset. Those characters are mapped as MAC-one in glnames.py, so they
cannot be shown in Adobe Type1 fonts.
(This was due to a bug in the "glnames.py" script used to generate the
table of glyph names in 'src/psaux/pstables.h'.)
BAD-UNIXXXX-NAMES
Glyph names like uniXXXX are not recognized as they should be. It seems
that code in psmodule.c for uniXXXX glyph names was never tested. The
patch is very simple.
(A simple bug that was left un-noticed due to the fact that I don't have
any Postscript font that use this convention, unfortunately.)
GLYPH_TO_BITMAP-BUG
Calling FT_Glyph_To_Bitmap() sometimes modifies the original glyph
outline, creating weird alignment artefacts.
This subtle bug was really in the file `src/smooth/ftsmooth.c'.
Basically, the outline was shifted before rendering it into a new bitmap
buffer. However, it wasn't properly un-shifted after that operation.
This was only noticeable with certain glyphs or certain fonts; it crept in
a long time ago.
The same bug has been fixed in src/raster/ftrender1.c also.
TT-GLYPH-CRASH
The library crashed when trying to load certain glyphs from an
automatically generated TrueType file (tt1095m_.ttf submitted by Scott
Long).
It turned out that the font contained invalid glyph data (i.e. was
broken), but the TrueType glyph loader in FreeType wasn't paranoid enough,
which resulted in nasty memory overwrites all over the place.
T1-FONT-CRASH
The library crashed when trying to load the "Stalingrad Regular" face from
the "sadn.pfb" font file provided by Anthony Fok (and the Gnome-Print team
I believe).
This was due to the fact that the font missed a full font name entry,
though boasted a family name and postscript name. The Type 1 face loader
didn't check for these pathetic cases and seg-faulted.
BAD-ADVANCES
All scalable font drivers returned un-fitted glyph advances when
FT_LOAD_DEFAULT was used, which was incorrect. This problem was pretty
old but hadn't been spotted because all test programs actually explicitly
or implicitly (i.e. through the cache) rounded the advance widths of
glyphs.
This resulted in poor rendering of a number of client applications however
(it is strange to see they took so long to notify the FreeType team).
GLYPH-TO-BITMAP-BUG
FT_Glyph_To_Bitmap() did incorrectly modify the source glyph in certain
cases, which resulted in random behaviour and bad text rendering. This
was spotted to bugs in both the monochrome and smooth rasterizer.

FreeType 2 compilation how-to
=============================
Introduction
------------
Welcome to the FreeType 2 library. You'll find in this document
instructions on how to compile the library on your favorite platform.
I. QUICK COMMAND-LINE GUIDE
---------------------------
THE FOLLOWING WILL ONLY WORK WITH GNU MAKE, IT WILL FAIL MISERABLY
WITH OTHER MAKE TOOLS, FOR EXAMPLE "BSD MAKE".
Install GNU Make (version 3.78.1 or newer), then try the following
on Unix or any system with gcc:
make // this will setup the build
make // this will build the library
On Win32 + Visual C++:
make setup visualc // setup the build for VisualC++ on Win32
make // build the library
Then, go to the `demos' directory and type
make
Note that on Unix, the first `make' invocation will run a configure
script (which is located in `freetype2/builds/unix/'. You can also
pass parameters to this script with the CFG variable, as in:
make CFG="--prefix=/usr/local"
make
If this doesn't work, read the following.
II. COMMAND-LINE COMPILATION
----------------------------
Note that if you do not want to compile FreeType 2 from a command
line shell, please skip to section III below (DETAILED COMPILATION).
FreeType 2 includes a powerful and flexible build system that allows
you to easily compile it on a great variety of platforms from the
command line. To do so, just follow these simple instructions:
a. Install GNU Make
Because GNU Make is the only Make tool supported to compile
FreeType 2, you should install it on your machine.
The FreeType 2 build system relies on many features special to GNU
Make -- trying to build the library with any other Make tool will
*fail*.
NEARLY ALL OTHER MAKE TOOLS WILL FAIL, INCLUDING "BSD MAKE", SO
REALLY INSTALL A RECENT VERSION OF GNU MAKE ON YOUR SYSTEM!
Make sure that you are invoking GNU Make from the command line, by
typing something like:
make -v
to display its version number.
VERSION 3.78.1 OR NEWER IS NEEDED!
b. Invoke `make'
Go to the root directory of FreeType 2, then simply invoke GNU
Make from the command line. This will launch the FreeType 2 host
platform detection routines. A summary will be displayed, for
example, on Win32:
==============================================================
FreeType build system -- automatic system detection
The following settings are used:
platform win32
compiler gcc
configuration directory ./builds/win32
configuration rules ./builds/win32/w32-gcc.mk
If this does not correspond to your system or settings please
remove the file 'config.mk' from this directory then read the
INSTALL file for help.
Otherwise, simply type 'make' again to build the library.
=============================================================
If the detected settings correspond to your platform and compiler,
skip to step e. Note that if your platform is completely alien to
the build system, the detected platform will be `ansi'.
c. Configure the build system for a different compiler
If the build system correctly detected your platform, but you want
to use a different compiler than the one specified in the summary
(for most platforms, gcc is the defaut compiler), invoke GNU Make
with
make setup <compiler>
For example:
to use Visual C++ on Win32, type: "make setup visualc"
to use LCC-Win32 on Win32, type: "make setup lcc"
The <compiler> name to use is platform-dependent. The list of
available compilers for your system is available in the file
`builds/<system>/detect.mk' (note that we hope to make the list
displayed at user demand in the final release).
If you are satisfied by the new configuration summary, skip to
step e.
d. Configure the build system for an unknown platform/compiler
The auto-detection/setup phase of the build system copies a file
to the current directory under the name `config.mk'.
For example, on OS/2+gcc, it would simply copy
`builds/os2/os2-gcc.mk' to `./config.mk'.
If for some reason your platform isn't correctly detected, copy
manually the configuration sub-makefile to `./config.mk' and go to
step e.
Note that this file is a sub-Makefile used to specify Make
variables for compiler and linker invocation during the build.
You can easily create your own version from one of the existing
configuration files, then copy it to the current directory under
the name `./config.mk'.
e. Build the library
The auto-detection/setup phase should have copied a file in the
current directory, called `./config.mk'. This file contains
definitions of various Make variables used to invoke the compiler
and linker during the build.
To launch the build, simply invoke GNU Make again: The top
Makefile will detect the configuration file and run the build with
it.
f. Build the demonstration programs
III. DETAILED COMPILATION PROCEDURE
-----------------------------------
If you don't want to compile FreeType 2 from the command-line (for
example if you use a graphical IDE on a Mac or Windows), you will
need to understand how the FreeType files are organized.
FreeType 2 has a very modular design, and it is made of several
components. Each component must be compiled as a stand-alone object
file, even if it is really made of several C source files. For
example, the `base layer' component is made of the following C
files:
src/
base/
ftcalc.c - computations
ftextend.c - extensions support
ftlist.c - simple list management
ftobjs.c - object management
ftoutln.c - simple outline processing
ftstream.c - stream input
However, you can create a single object file by compiling the file
`src/base/ftbase.c', which basically contains
#include "ftcalc.c"
#include "ftobjs.c"
#include "ftstream.c"
#include "ftlist.c"
#include "ftoutln.c"
#include "ftextend.c"
Similarly, each component has a single `englobing' C file to compile
it as a stand-alone object:
src/autohint/autohint.c - the autohinting module
src/base/ftbase.c - the base layer, high-level interface
src/cache/ftcache.c - a glyph and image caching system
(still experimental)
src/cff/cff.c - the OpenType font driver
src/cid/type1cid.c - the CID-keyed font driver
src/psaux/psaux.c - the PS support module
src/psnames/psnames.c - a support module to handle PS glyph
names
src/raster1/raster1.c - the monochrome raster module
src/sfnt/sfnt.c - the `sfnt' module
src/smooth/smooth.c - the anti-aliasing raster module
src/truetype/truetype.c - the TrueType font driver
src/type1/type1.c - the Type 1 font driver
The last module of FreeType 2, `winfonts' (implementing support for
Windows FNT format), is a single file.
To compile one component, do the following:
- Add the top-level `include' directory to your compilation
include path
- Add the `src/<component>' directory to your compilation include
path, or simply `cd' to the component's source directory.
- Compile the component `source' file (see list below); you don't
need to be in the component's directory if you added
`src/<component>' to your include path.
For example, the following line can be used to compile the truetype
driver on Unix:
cd freetype2/
cc -c -Iinclude -Isrc/truetype src/truetype/truetype.c
Alternatively:
cd freetype2/src/truetype
cc -c -I../../include truetype.c
Finally, FreeType 2 contains some other components:
src/base/ftsystem.c - system-specific memory and i/o support
src/base/ftinit.c - initialization layer
src/base/ftdebug.c - debugging component (empty in release
build)
src/base/ftglyph.c - optional convenience functions
All font drivers are optional. The `sfnt', `psaux', and `psnames'
modules are mandatory for certain drivers. However, you may need to
update the list of drivers that are statically linked to the
library, which is located in the configuration file
`include/freetype/config/ftmodule.h'.
IV. Support for flat-directory compilation
------------------------------------------
It is possible to put all FreeType 2 source files into a single
directory, with the exception of the `include' hierarchy.
1. Copy all files in current directory:
cp freetype2/src/base/*.[hc] .
cp freetype2/src/raster1/*.[hc] .
cp freetype2/src/smooth/*.[hc] .
etc.
2. Compile sources:
cc -c -Ifreetype2/include ftsystem.c
cc -c -Ifreetype2/include ftinit.c
cc -c -Ifreetype2/include ftdebug.c
cc -c -Ifreetype2/include ftbase.c
etc.
You don't need to define the FT_FLAT_COMPILATION macro (as this was
required in previous releases of FreeType 2).

59 Temple Place - Suite 330, Boston, MA 02111-1307, USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Library General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
Appendix: How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) 19yy <name of author>
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program; if not, write to the Free Software
Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) 19yy name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
`Gnomovision' (which makes passes at compilers) written by James Hacker.

This General Public License does not permit incorporating your program into
proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Library General
Public License instead of this License.

In order to build the library, read the `BUILD' document in the `docs'
directory. This is only a quick starter.
I. Unix systems
---------------
If you have GNU Make installed, simply type
./configure
make
make install
on the command line to configure, build and install FreeType on your
system. Note that the default installation path is "/usr/local".
Please read the file README.UNX, it contains _critical_ information
regarding the installation of FreeType on many Unix systems.
II. From the command line
-------------------------
If you are not using Unix, there are two ways to quickly build
FreeType 2 from the command line.
The first, and favorite one, is to use the "Jam" build tool. Jam is
a highly portable replacement for Make whose control files do not
depend on the current platform or compiler toolset.
For more information, please see:
http://www.freetype.org/jam/index.html
The second one is to use "GNU Make" (and NO OTHER MAKE TOOL).
1. Building FT2 with "Jam"
--------------------------
Once you've got *our version* of the Jam tool installed on your
system, simply go to the top-level FT2 directory, then type
"jam"
on the command line. This will build the library and place it in
the "objs" directory.
By default, a static library is built. On Unix systems, it is
possible to build a shared library through the "libtool" script.
You need to have libtool installed on your system, then re-define
a few environment variables before invoking Jam, as in
export CC="libtool --mode=compile cc"
export LINK="libtool --mode=link cc"
jam
In later releases of FT2, building shared libraries with Jam
should become automatic on Unix systems.
2. Building FT2 with "GNU Make"
-------------------------------
You need to have GNU Make (version 3.78.1 or newer) installed on
your system to compile the library from the command line. This will
_NOT_ work with other make tools (including BSD make)!
[Well, this is not really correct. Recently, a perl implementation
of make called `makepp' has appeared which can also build FreeType 2
successfully on Unix platforms. See http://makepp.sourceforge.net
for more details.]
- Go to the `freetype2' directory.
- Unix (any C compiler should work):
- make setup (don't worry, this will invoke a configure script)
- make
- make install
Alternatively, you can pass parameters to the configure script
within the CFG variable, as in:
- make setup CFG="--prefix=/usr"
- make
- make install
If the configure script isn't run, try to add `unix' as a target
on the command line, e.g.:
- make setup unix CFG="--prefix=/opt/experimental"
- Windows:
We provide a version of GNU Make for Win32 on the FreeType site.
See http://www.freetype.org/download.html for details.
- gcc (Mingw, _not_ CygWin):
- make setup
- make
- Visual C++:
- make setup visualc
- make
- other compilers:
- make setup bcc32 -> Borland C++ 32 bits
- make setup intelc -> Intel C++
- make setup watcom -> Watcom C++
- make setup lcc -> Win32-LCC
If you want to build FreeType 2 in another directory, you must set
two environment variables, `OJB_DIR' and `TOP_DIR'. The former
gives the directory where the object files and the library should be
created (this directory must exist), the latter the top directory of
the FreeType 2 source tree. Example:
OBJ_DIR=~/freetype2.compiled TOP_DIR=~/freetype2 \
make -f$TOP_DIR/Makefile setup ansi
OBJ_DIR=~/freetype2.compiled TOP_DIR=~/freetype2 \
make -f$TOP_DIR/Makefile
On Unix boxes, calling `configure' from the build directory is
sufficient; it will build a small Makefile which calls the
FreeType 2 Makefile with the necessary parameters.
III. In your own environment (IDE)
----------------------------------
You need to add the directories "freetype2/include" to your include
path when compiling the library.
FreeType 2 is made of several components; each one of them is
located in a subdirectory of "freetype2/src". For example,
`freetype2/src/truetype/' contains the TrueType font driver.
DO NOT COMPILE ALL C FILES! Rather, compile the following ones:
-- base components (required)
src/base/ftsystem.c
src/base/ftinit.c
src/base/ftdebug.c
src/base/ftbase.c
src/base/ftglyph.c
src/base/ftbbox.c
src/base/ftmm.c
src/base/ftmac.c -- only on the Macintosh
-- other components are optional
src/autohint/autohint.c -- auto hinting module
src/cache/ftcache.c -- cache sub-system (in beta)
src/sfnt/sfnt.c -- SFNT files support
(TrueType & OpenType)
src/cff/cff.c -- CFF/OpenType font driver
src/psnames/psnames.c -- Postscript glyph names support
src/psaux/psaux.c -- Postscript Type 1 parsing
src/truetype/truetype.c -- TrueType font driver
src/type1/type1.c -- Type 1 font driver
src/cid/type1cid.c -- Type 1 CID-keyed font driver
src/winfonts/winfonts.c -- Windows FONT / FNT font driver
Note:
`truetype.c' needs `sfnt.c' and `psnames.c'
`type1.c' needs `psaux.c' and `psnames.c'
`type1cid.c' needs `psaux.c' and `psnames.c'
`cff.c' needs `sfnt.c', `psaux.c', and `psnames.c'
etc.
For more information, please consult "docs/BUILD".

Note that the list of known bugs for FreeType 2 is now located in the
document "docs/BUGS".
Here is a list of items that need to be addressed in FreeType 2; they are
not exactly bugs, but should be considered though:
* Add synthesized Unicode charmap processing to the CFF driver.
* Implement stem3/counter hints properly in the Postscript hinter.

FreeType comes with two licenses from which you can choose the one which
fits your needs best:
. The FreeType License, in file `docs/FTL.txt'.
. The GNU General Public License, in file `docs/GPL.txt'.
The contributed PCF driver comes with a license similar to that of X Window

How to build the freetype2 library on VMS
-----------------------------------------
Just type one of the following depending on the type of external entries you
want:
mms
or
mms/macro=("COMP_FLAGS=/name=(as_is,short)")
The library is avalaible in the directory
[.LIB]
To compile applications using freetype2 you'll need to define the logical
FREETYPE pointing to the directory
[.INCLUDE.FREETYPE]
(i.e., if the directory in which this README.VMS file is located is
$disk:[freetype] then define the logical with
define freetype $disk:[freetype.include.freetype]
This version has been tested with Compaq C V6.2-006 on OpenVMS Alpha V7.2-1.

/* 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 */
/* ----------------- */
/* */
/* Since release 2.1, the error constants have changed. The lower */
/* byte of the error value gives the "generic" error code, while the */
/* higher byte indicates in which module the error occurred. */
/* */
/* You can use the macro FT_ERROR_BASE(x) macro to extract the generic */
/* error code from an FT_Error value. */
/* */
/* The configuration macro FT_CONFIG_OPTION_USE_MODULE_ERRORS can be */
/* undefined in ftoption.h in order to make the higher byte always */
/* zero, in case you need to be compatible with previous versions of */
/* FreeType 2. */
/* */
/* */
/* 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__ */
/* #define FT_ERRORDEF( e, v, s ) { e, s }, */
/* #define FT_ERROR_START_LIST { */

/* 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 */
/* agressively 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. */
