+ The FreeType Project LICENSE
+ ----------------------------
+
+ 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
+-----------
+
+ There are two mailing lists related to FreeType:
+
+ o freetype@nongnu.org
+
+ Discusses general use and applications of FreeType, as well as
+ future and wanted additions to the library and distribution.
+ If you are looking for support, start in this list if you
+ haven't found anything to help you in the documentation.
+
+ o freetype-devel@nongnu.org
+
+ Discusses bugs, as well as engine internals, design issues,
+ specific licenses, porting, etc.
+
+ Our home page can be found at
+

+ * @title:
+ * The TrueType driver
+ *
+ * @abstract:
+ * Controlling the TrueType driver module.
+ *
+ * @description:
+ * While FreeType's TrueType driver doesn't expose API functions by
+ * itself, it is possible to control its behaviour with @FT_Property_Set
+ * and @FT_Property_Get. The following lists the available properties
+ * together with the necessary macros and structures.
+ *
+ * The TrueType driver's module name is `truetype'.
+ *
+ * We start with a list of definitions, kindly provided by Greg
+ * Hitchcock.
+ *
+ * _Bi-Level_ _Rendering_
+ *
+ * Monochromatic rendering, exclusively used in the early days of
+ * TrueType by both Apple and Microsoft. Microsoft's GDI interface
+ * supported hinting of the right-side bearing point, such that the
+ * advance width could be non-linear. Most often this was done to
+ * achieve some level of glyph symmetry. To enable reasonable
+ * performance (e.g., not having to run hinting on all glyphs just to
+ * get the widths) there was a bit in the head table indicating if the
+ * side bearing was hinted, and additional tables, `hdmx' and `LTSH', to
+ * cache hinting widths across multiple sizes and device aspect ratios.
+ *
+ * _Font_ _Smoothing_
+ *
+ * Microsoft's GDI implementation of anti-aliasing. Not traditional
+ * anti-aliasing as the outlines were hinted before the sampling. The
+ * widths matched the bi-level rendering.
+ *
+ * _ClearType_ _Rendering_
+ *
+ * Technique that uses physical subpixels to improve rendering on LCD
+ * (and other) displays. Because of the higher resolution, many methods
+ * of improving symmetry in glyphs through hinting the right-side
+ * bearing were no longer necessary. This lead to what GDI calls
+ * `natural widths' ClearType, see
+ * http://www.beatstamm.com/typography/RTRCh4.htm#Sec21. Since hinting
+ * has extra resolution, most non-linearity went away, but it is still
+ * possible for hints to change the advance widths in this mode.
+ *
+ * _ClearType_ _Compatible_ _Widths_
+ *
+ * One of the earliest challenges with ClearType was allowing the
+ * implementation in GDI to be selected without requiring all UI and
+ * documents to reflow. To address this, a compatible method of
+ * rendering ClearType was added where the font hints are executed once
+ * to determine the width in bi-level rendering, and then re-run in
+ * ClearType, with the difference in widths being absorbed in the font
+ * hints for ClearType (mostly in the white space of hints); see
+ * http://www.beatstamm.com/typography/RTRCh4.htm#Sec20. Somewhat by
+ * definition, compatible width ClearType allows for non-linear widths,
+ * but only when the bi-level version has non-linear widths.
+ *
+ * _ClearType_ _Subpixel_ _Positioning_
+ *
+ * One of the nice benefits of ClearType is the ability to more crisply
+ * display fractional widths; unfortunately, the GDI model of integer
+ * bitmaps did not support this. However, the WPF and Direct Write
+ * frameworks do support fractional widths. DWrite calls this `natural
+ * mode', not to be confused with GDI's `natural widths'. Subpixel
+ * positioning, in the current implementation of Direct Write,
+ * unfortunately does not support hinted advance widths, see
+ * http://www.beatstamm.com/typography/RTRCh4.htm#Sec22. Note that the
+ * TrueType interpreter fully allows the advance width to be adjusted in
+ * this mode, just the DWrite client will ignore those changes.
+ *
+ * _ClearType_ _Backwards_ _Compatibility_
+ *
+ * This is a set of exceptions made in the TrueType interpreter to
+ * minimize hinting techniques that were problematic with the extra
+ * resolution of ClearType; see
+ * http://www.beatstamm.com/typography/RTRCh4.htm#Sec1 and
+ * http://www.microsoft.com/typography/cleartype/truetypecleartype.aspx.
+ * This technique is not to be confused with ClearType compatible
+ * widths. ClearType backwards compatibility has no direct impact on
+ * changing advance widths, but there might be an indirect impact on
+ * disabling some deltas. This could be worked around in backwards
+ * compatibility mode.
+ *
+ * _Native_ _ClearType_ _Mode_
+ *
+ * (Not to be confused with `natural widths'.) This mode removes all
+ * the exceptions in the TrueType interpreter when running with
+ * ClearType. Any issues on widths would still apply, though.
+ *

+ *
+ * @property:
+ * interpreter-version
+ *
+ * @description:
+ * Currently, two versions are available, representing the bytecode
+ * interpreter with and without subpixel hinting support,
+ * respectively. The default is subpixel support if
+ * TT_CONFIG_OPTION_SUBPIXEL_HINTING is defined, and no subpixel
+ * support otherwise (since it isn't available then).
+ *
+ * If subpixel hinting is on, many TrueType bytecode instructions behave
+ * differently compared to B/W or grayscale rendering (except if `native
+ * ClearType' is selected by the font). The main idea is to render at a
+ * much increased horizontal resolution, then sampling down the created
+ * output to subpixel precision. However, many older fonts are not
+ * suited to this and must be specially taken care of by applying
+ * (hardcoded) font-specific tweaks.
+ *
+ * Details on subpixel hinting and some of the necessary tweaks can be
+ * found in Greg Hitchcock's whitepaper at
+ * `http://www.microsoft.com/typography/cleartype/truetypecleartype.aspx'.
+ *
+ * The following example code demonstrates how to activate subpixel
+ * hinting (omitting the error handling).

+ * @enum:
+ * TT_INTERPRETER_VERSION_XXX
+ *
+ * @description:
+ * A list of constants used for the @interpreter-version property to
+ * select the hinting engine for Truetype fonts.
+ *
+ * The numeric value in the constant names represents the version
+ * number as returned by the `GETINFO' bytecode instruction.
+ *
+ * @values:
+ * TT_INTERPRETER_VERSION_35 ::
+ * Version~35 corresponds to MS rasterizer v.1.7 as used e.g. in
+ * Windows~98; only grayscale and B/W rasterizing is supported.
+ *
+ * TT_INTERPRETER_VERSION_38 ::
+ * Version~38 corresponds to MS rasterizer v.1.9; it is roughly
+ * equivalent to the hinting provided by DirectWrite ClearType (as
+ * can be found, for example, in the Internet Explorer~9 running on
+ * Windows~7).
+ *
+ * @note:
+ * This property controls the behaviour of the bytecode interpreter
+ * and thus how outlines get hinted. It does *not* control how glyph
+ * get rasterized! In particular, it does not control subpixel color
+ * filtering.
+ *
+ * If FreeType has not been compiled with configuration option
+ * FT_CONFIG_OPTION_SUBPIXEL_HINTING, selecting version~38 causes an
+ * `FT_Err_Unimplemented_Feature' error.
+ *
+ * Depending on the graphics framework, Microsoft uses different
+ * bytecode and rendering engines. As a consequence, the version
+ * numbers returned by a call to the `GETINFO' bytecode instruction are
+ * more convoluted than desired.
+ *
+ * Here are two tables that try to shed some light on the possible
+ * values for the MS rasterizer engine, together with the additional
+ * features introduced by it.
+ *
+ * {
+ * GETINFO framework version feature
+ * -------------------------------------------------------------------
+ * 3 GDI (Win 3.1), v1.0 16-bit, first version
+ * TrueImage
+ * 33 GDI (Win NT 3.1), v1.5 32-bit
+ * HP Laserjet
+ * 34 GDI (Win 95) v1.6 font smoothing,
+ * new SCANTYPE opcode
+ * 35 GDI (Win 98/2000) v1.7 (UN)SCALED_COMPONENT_OFFSET
+ * bits in composite glyphs
+ * 36 MGDI (Win CE 2) v1.6+ classic ClearType
+ * 37 GDI (XP and later), v1.8 ClearType
+ * GDI+ old (before Vista)
+ * 38 GDI+ old (Vista, Win 7), v1.9 subpixel ClearType,
+ * WPF Y-direction ClearType,
+ * additional error checking
+ * 39 DWrite (before Win 8) v2.0 subpixel ClearType flags
+ * in GETINFO opcode,
+ * bug fixes
+ * 40 GDI+ (after Win 7), v2.1 Y-direction ClearType flag
+ * DWrite (Win 8) in GETINFO opcode,
+ * Gray ClearType
+ * }
+ *
+ * The `version' field gives a rough orientation only, since some
+ * applications provided certain features much earlier (as an example,
+ * Microsoft Reader used subpixel and Y-direction ClearType already in
+ * Windows 2000). Similarly, updates to a given framework might include
+ * improved hinting support.
+ *
+ * {
+ * version sampling rendering comment
+ * x y x y
+ * --------------------------------------------------------------
+ * v1.0 normal normal B/W B/W bi-level
+ * v1.6 high high gray gray grayscale
+ * v1.8 high normal color-filter B/W (GDI) ClearType
+ * v1.9 high high color-filter gray Color ClearType
+ * v2.1 high normal gray B/W Gray ClearType
+ * v2.1 high high gray gray Gray ClearType
+ * }
+ *
+ * Color and Gray ClearType are the two available variants of
+ * `Y-direction ClearType', meaning grayscale rasterization along the
+ * Y-direction; the name used in the TrueType specification for this
+ * feature is `symmetric smoothing'. `Classic ClearType' is the
+ * original algorithm used before introducing a modified version in
+ * Win~XP. Another name for v1.6's grayscale rendering is `font
+ * smoothing', and `Color ClearType' is sometimes also called `DWrite
+ * ClearType'. To differentiate between today's Color ClearType and the
+ * earlier ClearType variant with B/W rendering along the vertical axis,
+ * the latter is sometimes called `GDI ClearType'.
+ *
+ * `Normal' and `high' sampling describe the (virtual) resolution to
+ * access the rasterized outline after the hinting process. `Normal'
+ * means 1 sample per grid line (i.e., B/W). In the current Microsoft
+ * implementation, `high' means an extra virtual resolution of 16x16 (or
+ * 16x1) grid lines per pixel for bytecode instructions like `MIRP'.
+ * After hinting, these 16 grid lines are mapped to 6x5 (or 6x1) grid
+ * lines for color filtering if Color ClearType is activated.
+ *
+ * Note that `Gray ClearType' is essentially the same as v1.6's
+ * grayscale rendering. However, the GETINFO instruction handles it
+ * differently: v1.6 returns bit~12 (hinting for grayscale), while v2.1
+ * returns bits~13 (hinting for ClearType), 18 (symmetrical smoothing),
+ * and~19 (Gray ClearType). Also, this mode respects bits 2 and~3 for
+ * the version~1 gasp table exclusively (like Color ClearType), while
+ * v1.6 only respects the values of version~0 (bits 0 and~1).
+ *
+ * FreeType doesn't provide all capabilities of the most recent
+ * ClearType incarnation, thus we identify our subpixel support as
+ * version~38.

- *
- * @property:
- * interpreter-version
- *
- * @description:
- * Currently, two versions are available, representing the bytecode
- * interpreter with and without subpixel hinting support,
- * respectively. The default is subpixel support if
- * TT_CONFIG_OPTION_SUBPIXEL_HINTING is defined, and no subpixel
- * support otherwise (since it isn't available then).
- *
- * If subpixel hinting is on, many TrueType bytecode instructions
- * behave differently compared to B/W or grayscale rendering. The
- * main idea is to render at a much increased horizontal resolution,
- * then sampling down the created output to subpixel precision.
- * However, many older fonts are not suited to this and must be
- * specially taken care of by applying (hardcoded) font-specific
- * tweaks.
- *
- * Details on subpixel hinting and some of the necessary tweaks can be
- * found in Greg Hitchcock's whitepaper at
- * `http://www.microsoft.com/typography/cleartype/truetypecleartype.aspx'.
- *
- * The following example code demonstrates how to activate subpixel
- * hinting (omitting the error handling).
- *
- * {
- * FT_Library library;
- * FT_Face face;
- * FT_UInt interpreter_version = TT_INTERPRETER_VERSION_38;
- *
- *
- * FT_Init_FreeType( &library );
- *
- * FT_Property_Set( library, "truetype",
- * "interpreter-version",
- * &interpreter_version );
- * }
- *
- * @note:
- * This property can be used with @FT_Property_Get also.
- *
- */
-

- /**************************************************************************
- *
- * @enum:
- * TT_INTERPRETER_VERSION_XXX
- *
- * @description:
- * A list of constants used for the @interpreter-version property to
- * select the hinting engine for Truetype fonts.
- *
- * The numeric value in the constant names represents the version
- * number as returned by the `GETINFO' bytecode instruction.
- *
- * @values:
- * TT_INTERPRETER_VERSION_35 ::
- * Version~35 corresponds to MS rasterizer v.1.7 as used e.g. in
- * Windows~98; only grayscale and B/W rasterizing is supported.
- *
- * TT_INTERPRETER_VERSION_38 ::
- * Version~38 corresponds to MS rasterizer v.1.9; it is roughly
- * equivalent to the hinting provided by DirectWrite ClearType (as
- * can be found, for example, in the Internet Explorer~9 running on
- * Windows~7).
- *
- * @note:
- * This property controls the behaviour of the bytecode interpreter
- * and thus how outlines get hinted. It does *not* control how glyph
- * get rasterized! In particular, it does not control subpixel color
- * filtering.
- *
- * If FreeType has not been compiled with configuration option
- * FT_CONFIG_OPTION_SUBPIXEL_HINTING, selecting version~38 causes an
- * `FT_Err_Unimplemented_Feature' error.
- *
- * Depending on the graphics framework, Microsoft uses different
- * bytecode engines. As a consequence, the version numbers returned by
- * a call to the `GETINFO[1]' bytecode instruction are more convoluted
- * than desired.
- *
- * {
- * framework Windows version result of GETINFO[1]
- * ----------------------------------------------------
- * GDI before XP 35
- * GDI XP and later 37
- * GDI+ old before Vista 37
- * GDI+ old Vista, 7 38
- * GDI+ after 7 40
- * DWrite before 8 39
- * DWrite 8 and later 40
- * }
- *
- * Since FreeType doesn't provide all capabilities of DWrite ClearType,
- * using version~38 seems justified.
