|
||||
2006-Jan-27
|
||||
|
||||
Copyright 1996-2002, 2006 by
|
||||
David Turner, Robert Wilhelm, and Werner Lemberg
|
||||
|
||||
|
||||
|
||||
Introduction
|
||||
============
|
||||
|
||||
The FreeType Project is distributed in several archive packages;
|
||||
some of them may contain, in addition to the FreeType font engine,
|
||||
various tools and contributions which rely on, or relate to, the
|
||||
FreeType Project.
|
||||
|
||||
This license applies to all files found in such packages, and
|
||||
which do not fall under their own explicit license. The license
|
||||
affects thus the FreeType font engine, the test programs,
|
||||
documentation and makefiles, at the very least.
|
||||
|
||||
This license was inspired by the BSD, Artistic, and IJG
|
||||
(Independent JPEG Group) licenses, which all encourage inclusion
|
||||
and use of free software in commercial and freeware products
|
||||
alike. As a consequence, its main points are that:
|
||||
|
||||
o We don't promise that this software works. However, we will be
|
||||
interested in any kind of bug reports. (`as is' distribution)
|
||||
|
||||
o You can use this software for whatever you want, in parts or
|
||||
full form, without having to pay us. (`royalty-free' usage)
|
||||
|
||||
o You may not pretend that you wrote this software. If you use
|
||||
it, or only parts of it, in a program, you must acknowledge
|
||||
somewhere in your documentation that you have used the
|
||||
FreeType code. (`credits')
|
||||
|
||||
We specifically permit and encourage the inclusion of this
|
||||
software, with or without modifications, in commercial products.
|
||||
We disclaim all warranties covering The FreeType Project and
|
||||
assume no liability related to The FreeType Project.
|
||||
|
||||
|
||||
Finally, many people asked us for a preferred form for a
|
||||
credit/disclaimer to use in compliance with this license. We thus
|
||||
encourage you to use the following text:
|
||||
|
||||
"""
|
||||
Portions of this software are copyright © <year> The FreeType
|
||||
Project (www.freetype.org). All rights reserved.
|
||||
"""
|
||||
|
||||
Please replace <year> with the value from the FreeType version you
|
||||
actually use.
|
||||
|
||||
|
||||
Legal Terms
|
||||
===========
|
||||
|
||||
0. Definitions
|
||||
--------------
|
||||
|
||||
Throughout this license, the terms `package', `FreeType Project',
|
||||
and `FreeType archive' refer to the set of files originally
|
||||
distributed by the authors (David Turner, Robert Wilhelm, and
|
||||
Werner Lemberg) as the `FreeType Project', be they named as alpha,
|
||||
beta or final release.
|
||||
|
||||
`You' refers to the licensee, or person using the project, where
|
||||
`using' is a generic term including compiling the project's source
|
||||
code as well as linking it to form a `program' or `executable'.
|
||||
This program is referred to as `a program using the FreeType
|
||||
engine'.
|
||||
|
||||
This license applies to all files distributed in the original
|
||||
FreeType Project, including all source code, binaries and
|
||||
documentation, unless otherwise stated in the file in its
|
||||
original, unmodified form as distributed in the original archive.
|
||||
If you are unsure whether or not a particular file is covered by
|
||||
this license, you must contact us to verify this.
|
||||
|
||||
The FreeType Project is copyright (C) 1996-2000 by David Turner,
|
||||
Robert Wilhelm, and Werner Lemberg. All rights reserved except as
|
||||
specified below.
|
||||
|
||||
1. No Warranty
|
||||
--------------
|
||||
|
||||
THE FREETYPE PROJECT IS PROVIDED `AS IS' WITHOUT WARRANTY OF ANY
|
||||
KIND, EITHER EXPRESS OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
|
||||
WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
|
||||
PURPOSE. IN NO EVENT WILL ANY OF THE AUTHORS OR COPYRIGHT HOLDERS
|
||||
BE LIABLE FOR ANY DAMAGES CAUSED BY THE USE OR THE INABILITY TO
|
||||
USE, OF THE FREETYPE PROJECT.
|
||||
|
||||
2. Redistribution
|
||||
-----------------
|
||||
|
||||
This license grants a worldwide, royalty-free, perpetual and
|
||||
irrevocable right and license to use, execute, perform, compile,
|
||||
display, copy, create derivative works of, distribute and
|
||||
sublicense the FreeType Project (in both source and object code
|
||||
forms) and derivative works thereof for any purpose; and to
|
||||
authorize others to exercise some or all of the rights granted
|
||||
herein, subject to the following conditions:
|
||||
|
||||
o Redistribution of source code must retain this license file
|
||||
(`FTL.TXT') unaltered; any additions, deletions or changes to
|
||||
the original files must be clearly indicated in accompanying
|
||||
documentation. The copyright notices of the unaltered,
|
||||
original files must be preserved in all copies of source
|
||||
files.
|
||||
|
||||
o Redistribution in binary form must provide a disclaimer that
|
||||
states that the software is based in part of the work of the
|
||||
FreeType Team, in the distribution documentation. We also
|
||||
encourage you to put an URL to the FreeType web page in your
|
||||
documentation, though this isn't mandatory.
|
||||
|
||||
These conditions apply to any software derived from or based on
|
||||
the FreeType Project, not just the unmodified files. If you use
|
||||
our work, you must acknowledge us. However, no fee need be paid
|
||||
to us.
|
||||
|
||||
3. Advertising
|
||||
--------------
|
||||
|
||||
Neither the FreeType authors and contributors nor you shall use
|
||||
the name of the other for commercial, advertising, or promotional
|
||||
purposes without specific prior written permission.
|
||||
|
||||
We suggest, but do not require, that you use one or more of the
|
||||
following phrases to refer to this software in your documentation
|
||||
or advertising materials: `FreeType Project', `FreeType Engine',
|
||||
`FreeType library', or `FreeType Distribution'.
|
||||
|
||||
As you have not signed this license, you are not required to
|
||||
accept it. However, as the FreeType Project is copyrighted
|
||||
material, only this license, or another one contracted with the
|
||||
authors, grants you the right to use, distribute, and modify it.
|
||||
Therefore, by using, distributing, or modifying the FreeType
|
||||
Project, you indicate that you understand and accept all the terms
|
||||
of this license.
|
||||
|
||||
4. Contacts

GNU GENERAL PUBLIC LICENSE
|
||||
Version 2, June 1991
|
||||
|
||||
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
|
||||
51 Franklin St, Fifth Floor, Boston, MA 02110-1301 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

|

|

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 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
|

REPAIR OR CORRECTION.

12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING

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
|

|

POSSIBILITY OF SUCH DAMAGES.
|
||||
|
||||
END OF TERMS AND CONDITIONS
|
||||
|
||||
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) <year> <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., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 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) year 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
|
||||

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.

The FreeType 2 font engine is copyrighted work and cannot be used
|
||||
legally without a software license. In order to make this project
|
||||
usable to a vast majority of developers, we distribute it under two
|
||||
mutually exclusive open-source licenses.
|
||||
|
||||
This means that *you* must choose *one* of the two licenses described
|
||||
below, then obey all its terms and conditions when using FreeType 2 in
|
||||
any of your projects or products.
|
||||
|
||||
- The FreeType License, found in the file `FTL.TXT', which is similar
|
||||
to the original BSD license *with* an advertising clause that forces
|
||||
you to explicitly cite the FreeType project in your product's
|
||||
documentation. All details are in the license file. This license
|
||||
is suited to products which don't use the GNU General Public
|
||||
License.
|
||||
|
||||
Note that this license is compatible to the GNU General Public
|
||||
License version 3, but not version 2.
|
||||
|
||||
- The GNU General Public License version 2, found in `GPLv2.TXT' (any
|
||||
later version can be used also), for programs which already use the
|
||||
GPL. Note that the FTL is incompatible with GPLv2 due to its
|
||||
advertisement clause.
|
||||
|
||||
The contributed BDF and PCF drivers come with a license similar to that
|
||||
of the X Window System. It is compatible to the above two licenses (see
|
||||
file src/bdf/README and src/pcf/README).
|
||||
|
||||
The gzip module uses the zlib license (see src/gzip/zlib.h) which too is
|
||||
compatible to the above two licenses.

# FreeType Amalgamation
|
||||
|
||||
A distribution of the [FreeType][1] library in amalgamated source code form.
|
||||
|
||||
## What's an amalgamation?
|
||||
|
||||
An amalgamation is simply a collection of header and source files that have been
|
||||
concatenated together to form one or more very large files. In this form, they
|
||||
are easy to add to your existing project as source files (rather than linking
|
||||
as a library). They are also easier to redistribute if you are making an open
|
||||
source application and don't want to have any external dependencies.
|
||||
|
||||
## What is FreeType?
|
||||
|
||||
FreeType 2 is a software font engine that is designed to be small,
|
||||
efficient, highly customizable, and portable while capable of producing
|
||||
high-quality output (glyph images). It can be used in graphics libraries,
|
||||
display servers, font conversion tools, text image generation tools, and
|
||||
many other products as well.
|
||||
|
||||
## How do I use this?
|
||||
|
||||
Add FreeTypeAmalgam.c to your existing project, include FreeTypeAmalgam.h
|
||||
in the source files where you want to use FreeType, and that's it!
|
||||
|
||||
The [FreeType Amalgmation][4] was built using the [Amalgamate Templates][3].
