-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

- /* 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. */

- *
- * @enum:
- * FT_LOAD_XXX
- *
- * @description:
- * A list of bit-field constants used with @FT_Load_Glyph to indicate
- * what kind of operations to perform during glyph loading.
- *
- * @values:
- * FT_LOAD_DEFAULT ::
- * Corresponding to 0, this value is used as the default glyph load
- * operation. In this case, the following happens:
- *
- * 1. FreeType looks for a bitmap for the glyph corresponding to the
- * face's current size. If one is found, the function returns.
- * The bitmap data can be accessed from the glyph slot (see note
- * below).
- *
- * 2. If no embedded bitmap is searched or found, FreeType looks for a
- * scalable outline. If one is found, it is loaded from the font
- * file, scaled to device pixels, then `hinted' to the pixel grid
- * in order to optimize it. The outline data can be accessed from
- * the glyph slot (see note below).
- *
- * Note that by default, the glyph loader doesn't render outlines into
- * bitmaps. The following flags are used to modify this default
- * behaviour to more specific and useful cases.
- *
- * FT_LOAD_NO_SCALE ::
- * Don't scale the outline glyph loaded, but keep it in font units.
- *
- * This flag implies @FT_LOAD_NO_HINTING and @FT_LOAD_NO_BITMAP, and
- * unsets @FT_LOAD_RENDER.
- *
- * FT_LOAD_NO_HINTING ::
- * Disable hinting. This generally generates `blurrier' bitmap glyph
- * when the glyph is rendered in any of the anti-aliased modes. See
- * also the note below.
- *
- * This flag is implied by @FT_LOAD_NO_SCALE.
- *
- * FT_LOAD_RENDER ::
- * Call @FT_Render_Glyph after the glyph is loaded. By default, the
- * glyph is rendered in @FT_RENDER_MODE_NORMAL mode. This can be
- * overridden by @FT_LOAD_TARGET_XXX or @FT_LOAD_MONOCHROME.
- *
- * This flag is unset by @FT_LOAD_NO_SCALE.
- *
- * FT_LOAD_NO_BITMAP ::
- * Ignore bitmap strikes when loading. Bitmap-only fonts ignore this
- * flag.
- *
- * @FT_LOAD_NO_SCALE always sets this flag.
- *
- * FT_LOAD_VERTICAL_LAYOUT ::
- * Load the glyph for vertical text layout. _Don't_ use it as it is
- * problematic currently.
- *
- * FT_LOAD_FORCE_AUTOHINT ::
- * Indicates that the auto-hinter is preferred over the font's native
- * hinter. See also the note below.
- *
- * FT_LOAD_CROP_BITMAP ::
- * Indicates that the font driver should crop the loaded bitmap glyph
- * (i.e., remove all space around its black bits). Not all drivers
- * implement this.
- *
- * FT_LOAD_PEDANTIC ::
- * Indicates that the font driver should perform pedantic verifications
- * during glyph loading. This is mostly used to detect broken glyphs
- * in fonts. By default, FreeType tries to handle broken fonts also.
- *
- * FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH ::
- * Indicates that the font driver should ignore the global advance
- * width defined in the font. By default, that value is used as the
- * advance width for all glyphs when the face has
- * @FT_FACE_FLAG_FIXED_WIDTH set.
- *
- * This flag exists for historical reasons (to support buggy CJK
- * fonts).
- *
- * FT_LOAD_NO_RECURSE ::
- * This flag is only used internally. It merely indicates that the
- * font driver should not load composite glyphs recursively. Instead,
- * it should set the `num_subglyph' and `subglyphs' values of the
- * glyph slot accordingly, and set `glyph->format' to
- * @FT_GLYPH_FORMAT_COMPOSITE.
- *
- * The description of sub-glyphs is not available to client
- * applications for now.
- *
- * This flag implies @FT_LOAD_NO_SCALE and @FT_LOAD_IGNORE_TRANSFORM.
- *
- * FT_LOAD_IGNORE_TRANSFORM ::
- * Indicates that the transform matrix set by @FT_Set_Transform should
- * be ignored.
- *
- * FT_LOAD_MONOCHROME ::
- * This flag is used with @FT_LOAD_RENDER to indicate that you want to
- * render an outline glyph to a 1-bit monochrome bitmap glyph, with
- * 8 pixels packed into each byte of the bitmap data.
- *
- * Note that this has no effect on the hinting algorithm used. You
- * should use @FT_LOAD_TARGET_MONO instead so that the
- * monochrome-optimized hinting algorithm is used.
- *
- * FT_LOAD_LINEAR_DESIGN ::
- * Indicates that the `linearHoriAdvance' and `linearVertAdvance'
- * fields of @FT_GlyphSlotRec should be kept in font units. See
- * @FT_GlyphSlotRec for details.
- *
- * FT_LOAD_NO_AUTOHINT ::
- * Disable auto-hinter. See also the note below.
- *
- *
- * FT_LOAD_ADVANCE_ONLY ::
- * Try to only load the glyph advance, and nothing else. when set, the
- * content of face->glyph might be garbage, except for the
- * face->glyph.advance vector.
- *
- * @note:
- * By default, hinting is enabled and the font's native hinter (see
- * @FT_FACE_FLAG_HINTER) is preferred over the auto-hinter. You can
- * disable hinting by setting @FT_LOAD_NO_HINTING or change the
- * precedence by setting @FT_LOAD_FORCE_AUTOHINT. You can also set
- * @FT_LOAD_NO_AUTOHINT in case you don't want the auto-hinter to be
- * used at all.
- *
- * Besides deciding which hinter to use, you can also decide which
- * hinting algorithm to use. See @FT_LOAD_TARGET_XXX for details.

- *
- * @enum:

- *
- * @description:
- * A list of values that are used to select a specific hinting algorithm
- * to use by the hinter. You should OR one of these values to your
- * `load_flags' when calling @FT_Load_Glyph.
- *
- * Note that font's native hinters may ignore the hinting algorithm you
- * have specified (e.g., the TrueType bytecode interpreter). You can set
- * @FT_LOAD_FORCE_AUTOHINT to ensure that the auto-hinter is used.
- *
- * Also note that @FT_LOAD_TARGET_LIGHT is an exception, in that it
- * always implies @FT_LOAD_FORCE_AUTOHINT.
- *
- * @values:
- * FT_LOAD_TARGET_NORMAL ::
- * This corresponds to the default hinting algorithm, optimized for
- * standard gray-level rendering. For monochrome output, use
- * @FT_LOAD_TARGET_MONO instead.
- *
- * FT_LOAD_TARGET_LIGHT ::
- * A lighter hinting algorithm for non-monochrome modes. Many
- * generated glyphs are more fuzzy but better resemble its original
- * shape. A bit like rendering on Mac OS X.
- *
- * As a special exception, this target implies @FT_LOAD_FORCE_AUTOHINT.
- *
- * FT_LOAD_TARGET_MONO ::
- * Strong hinting algorithm that should only be used for monochrome
- * output. The result is probably unpleasant if the glyph is rendered
- * in non-monochrome modes.
- *
- * FT_LOAD_TARGET_LCD ::
- * A variant of @FT_LOAD_TARGET_NORMAL optimized for horizontally
- * decimated LCD displays.
- *
- * FT_LOAD_TARGET_LCD_V ::
- * A variant of @FT_LOAD_TARGET_NORMAL optimized for vertically
- * decimated LCD displays.
- *
- * @note:
- * You should use only _one_ of the FT_LOAD_TARGET_XXX values in your
- * `load_flags'. They can't be ORed.
- *
- * If @FT_LOAD_RENDER is also set, the glyph is rendered in the
- * corresponding mode (i.e., the mode which matches the used algorithm
- * best) unless @FT_LOAD_MONOCHROME is set.
- *
- * You can use a hinting algorithm that doesn't correspond to the same
- * rendering mode. As an example, it is possible to use the `light'
- * hinting algorithm and have the results rendered in horizontal LCD
- * pixel mode, with code like
- *
- * {
- * FT_Load_Glyph( face, glyph_index,
- * load_flags | FT_LOAD_TARGET_LIGHT );

- * <Title>
- * Cache Sub-System
- *
- * <Abstract>
- * How to cache face, size, and glyph data with FreeType 2.
- *
- * <Description>
- * This section describes the FreeType 2 cache sub-system, which is used
- * to limit the number of concurrently opened @FT_Face and @FT_Size
- * objects, as well as caching information like character maps and glyph
- * images while limiting their maximum memory usage.
- *
- * Note that all types and functions begin with the `FTC_' prefix.
- *
- * The cache is highly portable and thus doesn't know anything about the
- * fonts installed on your system, or how to access them. This implies
- * the following scheme:
- *
- * First, available or installed font faces are uniquely identified by
- * @FTC_FaceID values, provided to the cache by the client. Note that
- * the cache only stores and compares these values, and doesn't try to
- * interpret them in any way.
- *
- * Second, the cache calls, only when needed, a client-provided function
- * to convert a @FTC_FaceID into a new @FT_Face object. The latter is
- * then completely managed by the cache, including its termination
- * through @FT_Done_Face.
- *
- * Clients are free to map face IDs to anything else. The most simple
- * usage is to associate them to a (pathname,face_index) pair that is
- * used to call @FT_New_Face. However, more complex schemes are also
- * possible.
- *
- * Note that for the cache to work correctly, the face ID values must be
- * *persistent*, which means that the contents they point to should not
- * change at runtime, or that their value should not become invalid.
- *
- * If this is unavoidable (e.g., when a font is uninstalled at runtime),
- * you should call @FTC_Manager_RemoveFaceID as soon as possible, to let
- * the cache get rid of any references to the old @FTC_FaceID it may
- * keep internally. Failure to do so will lead to incorrect behaviour
- * or even crashes.
- *
- * To use the cache, start with calling @FTC_Manager_New to create a new
- * @FTC_Manager object, which models a single cache instance. You can
- * then look up @FT_Face and @FT_Size objects with
- * @FTC_Manager_LookupFace and @FTC_Manager_LookupSize, respectively.
- *
- * If you want to use the charmap caching, call @FTC_CMapCache_New, then
- * later use @FTC_CMapCache_Lookup to perform the equivalent of
- * @FT_Get_Char_Index, only much faster.
- *
- * If you want to use the @FT_Glyph caching, call @FTC_ImageCache, then
- * later use @FTC_ImageCache_Lookup to retrieve the corresponding
- * @FT_Glyph objects from the cache.
- *
- * If you need lots of small bitmaps, it is much more memory efficient
- * to call @FTC_SBitCache_New followed by @FTC_SBitCache_Lookup. This
- * returns @FTC_SBitRec structures, which are used to store small
- * bitmaps directly. (A small bitmap is one whose metrics and
- * dimensions all fit into 8-bit integers).
- *
- * We hope to also provide a kerning cache in the near future.

- /* 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__ */
- /* #define FT_ERRORDEF( e, v, s ) { e, s }, */
- /* #define FT_ERROR_START_LIST { */
- /* #define FT_ERROR_END_LIST { 0, 0 } }; */
- /* */
- /* const struct */
- /* { */
- /* int err_code; */
- /* const char* err_msg; */

- * @enum:
- * FT_WinFNT_ID_XXX
- *
- * @description:
- * A list of valid values for the `charset' byte in
- * @FT_WinFNT_HeaderRec. Exact mapping tables for the various cpXXXX
- * 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
- * ordering and minor deviations).
- *
- * FT_WinFNT_ID_CP1250 ::
- * A superset of East European ISO 8859-2 (with slightly different
- * ordering).
- *
- * FT_WinFNT_ID_CP1251 ::
- * A superset of Russian ISO 8859-5 (with different ordering).
- *
- * FT_WinFNT_ID_CP1252 ::
- * ANSI encoding. A superset of ISO 8859-1.
- *
- * FT_WinFNT_ID_CP1253 ::
- * A superset of Greek ISO 8859-7 (with minor modifications).
- *
- * FT_WinFNT_ID_CP1254 ::
- * A superset of Turkish ISO 8859-9.
- *
- * FT_WinFNT_ID_CP1255 ::
- * A superset of Hebrew ISO 8859-8 (with some modifications).
- *
- * FT_WinFNT_ID_CP1256 ::

- /* A small technical note regarding automatic hinting in order to */

- /* */
- /* 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. */

- /* */
- /* Converting an outline into a bitmap is achieved in several steps: */
- /* */
- /* 1 - Decomposing the outline into successive `profiles'. Each */
- /* profile is simply an array of scanline intersections on a given */
- /* dimension. A profile's main attributes are */
- /* */
- /* o its scanline position boundaries, i.e. `Ymin' and `Ymax'. */
- /* */
- /* o an array of intersection coordinates for each scanline */
- /* between `Ymin' and `Ymax'. */
- /* */
- /* o a direction, indicating whether it was built going `up' or */
- /* `down', as this is very important for filling rules. */
- /* */
- /* 2 - Sweeping the target map's scanlines in order to compute segment */
- /* `spans' which are then filled. Additionally, this pass */
- /* performs drop-out control. */
- /* */
- /* The outline data is parsed during step 1 only. The profiles are */
- /* built from the bottom of the render pool, used as a stack. The */
- /* following graphics shows the profile list under construction: */
- /* */
- /* ____________________________________________________________ _ _ */
- /* | | | | | */
- /* | profile | coordinates for | profile | coordinates for |--> */

- /* `ftraster' module. Actually, `ftgrays' computes the _exact_ */
- /* coverage of the outline on each pixel cell. */
- /* */
- /* It is based on ideas that I initially found in Raph Levien's */
- /* excellent LibArt graphics library (see http://www.levien.com/libart */
- /* for more information, though the web pages do not tell anything */
- /* about the renderer; you'll have to dive into the source code to */
- /* understand how it works). */
- /* */
- /* Note, however, that this is a _very_ different implementation */
- /* compared to Raph's. Coverage information is stored in a very */
- /* different way, and I don't use sorted vector paths. Also, it doesn't */
- /* use floating point values. */
- /* */
- /* This renderer has the following advantages: */
- /* */
- /* - It doesn't need an intermediate bitmap. Instead, one can supply a */
- /* callback function that will be called by the renderer to draw gray */
- /* spans on any target surface. You can thus do direct composition on */
- /* any kind of bitmap, provided that you give the renderer the right */
- /* callback. */
- /* */
- /* - A perfect anti-aliaser, i.e., it computes the _exact_ coverage on */
- /* each pixel cell. */
- /* */
- /* - It performs a single pass on the outline (the `standard' FT2 */
- /* renderer makes two passes). */
- /* */
- /* - It can easily be modified to render to _any_ number of gray levels */
- /* cheaply. */
- /* */
- /* - For small (< 20) pixel sizes, it is faster than the standard */
- /* renderer. */
