* @description:
* This section contains various functions used to perform so-called
* `incremental' glyph loading. This is a mode where all glyphs loaded
* from a given @FT_Face are provided by the client application.
*
* Apart from that, all other tables are loaded normally from the font
* file. This mode is useful when FreeType is used within another
* engine, e.g., a PostScript Imaging Processor.
*
* To enable this mode, you must use @FT_Open_Face, passing an
* @FT_Parameter with the @FT_PARAM_TAG_INCREMENTAL tag and an
* @FT_Incremental_Interface value. See the comments for
* @FT_Incremental_InterfaceRec for an example.

/* */
/* - 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 */

* Retrieve the value for the supplied key from a PostScript font.
*
* @input:
* face ::
* PostScript face handle.
*
* key ::
* An enumeration value representing the dictionary key to retrieve.
*
* idx ::
* For array values, this specifies the index to be returned.
*
* value ::
* A pointer to memory into which to write the value.
*
* valen_len ::
* The size, in bytes, of the memory supplied for the value.
*
* @output:
* value ::
* The value matching the above key, if it exists.
*
* @return:
* The amount of memory (in bytes) required to hold the requested
* value (if it exists, -1 otherwise).
*
* @note:
* The values returned are not pointers into the internal structures of
* the face, but are `fresh' copies, so that the memory containing them
* belongs to the calling application. This also enforces the
* `read-only' nature of these values, i.e., this function cannot be
* used to manipulate the face.
*
* `value' is a void pointer because the values returned can be of
* various types.
*
* If either `value' is NULL or `value_len' is too small, just the
* required memory size for the requested entry is returned.
*
* The `idx' parameter is used, not only to retrieve elements of, for
* example, the FontMatrix or FontBBox, but also to retrieve name keys
* from the CharStrings dictionary, and the charstrings themselves. It
* is ignored for atomic values.
*
* PS_DICT_BLUE_SCALE returns a value that is scaled up by 1000. To
* get the value as in the font stream, you need to divide by
* 65536000.0 (to remove the FT_Fixed scale, and the x1000 scale).
*
* IMPORTANT: Only key/value pairs read by the FreeType interpreter can
* be retrieved. So, for example, PostScript procedures such as NP,
* ND, and RD are not available. Arbitrary keys are, obviously, not be
* available either.
*
* If the font's format is not PostScript-based, this function returns
* the `FT_Err_Invalid_Argument' error code.

*
* @description:
* While FreeType's CFF driver doesn't expose API functions by itself,
* it is possible to control its behaviour with @FT_Property_Set and
* @FT_Property_Get.
*
* The CFF driver's module name is `cff'.
*
* Available properties are @hinting-engine, @no-stem-darkening,
* @darkening-parameters, and @random-seed, as documented in the
* @properties section.
*
*
* *Hinting* *and* *antialiasing* *principles* *of* *the* *new* *engine*
*
* The rasterizer is positioning horizontal features (e.g., ascender
* height & x-height, or crossbars) on the pixel grid and minimizing the
* amount of antialiasing applied to them, while placing vertical
* features (vertical stems) on the pixel grid without hinting, thus
* representing the stem position and weight accurately. Sometimes the
* vertical stems may be only partially black. In this context,
* `antialiasing' means that stems are not positioned exactly on pixel
* borders, causing a fuzzy appearance.
*
* There are two principles behind this approach.
*
* 1) No hinting in the horizontal direction: Unlike `superhinted'
* TrueType, which changes glyph widths to accommodate regular
* inter-glyph spacing, Adobe's approach is `faithful to the design' in
* representing both the glyph width and the inter-glyph spacing
* designed for the font. This makes the screen display as close as it
* can be to the result one would get with infinite resolution, while
* preserving what is considered the key characteristics of each glyph.
* Note that the distances between unhinted and grid-fitted positions at
* small sizes are comparable to kerning values and thus would be
* noticeable (and distracting) while reading if hinting were applied.
*
* One of the reasons to not hint horizontally is antialiasing for LCD
* screens: The pixel geometry of modern displays supplies three
* vertical subpixels as the eye moves horizontally across each visible
* pixel. On devices where we can be certain this characteristic is
* present a rasterizer can take advantage of the subpixels to add
* increments of weight. In Western writing systems this turns out to
* be the more critical direction anyway; the weights and spacing of
* vertical stems (see above) are central to Armenian, Cyrillic, Greek,
* and Latin type designs. Even when the rasterizer uses greyscale
* antialiasing instead of color (a necessary compromise when one
* doesn't know the screen characteristics), the unhinted vertical
* features preserve the design's weight and spacing much better than
* aliased type would.
*
* 2) Alignment in the vertical direction: Weights and spacing along the
* y~axis are less critical; what is much more important is the visual
* alignment of related features (like cap-height and x-height). The
* sense of alignment for these is enhanced by the sharpness of grid-fit
* edges, while the cruder vertical resolution (full pixels instead of
* 1/3 pixels) is less of a problem.
*
* On the technical side, horizontal alignment zones for ascender,
* x-height, and other important height values (traditionally called
* `blue zones') as defined in the font are positioned independently,
* each being rounded to the nearest pixel edge, taking care of
* overshoot suppression at small sizes, stem darkening, and scaling.
*
* Hstems (this is, hint values defined in the font to help align
* horizontal features) that fall within a blue zone are said to be
* `captured' and are aligned to that zone. Uncaptured stems are moved
* in one of four ways, top edge up or down, bottom edge up or down.
* Unless there are conflicting hstems, the smallest movement is taken
* to minimize distortion.

* The TrueType driver
*
* @abstract:

*
* @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'.
*
* A single property @interpreter-version is available, as documented in
* the @properties section.
*
* 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_ _Backward_ _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
* https://www.microsoft.com/typography/cleartype/truetypecleartype.aspx.
* This technique is not to be confused with ClearType compatible
* widths. ClearType backward 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 backward
* 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.

* fuzzy!
*
* Gamma correction essentially lightens fonts since shades of grey are
* shifted to higher pixel values (=~higher brightness) to match the
* original intention to the reality of our screens. The side-effect is
* that glyphs `thin out'. Mac OS~X and Adobe's proprietary font
* rendering library implement a counter-measure: stem darkening at
* smaller sizes where shades of gray dominate. By emboldening a glyph
* slightly in relation to its pixel size, individual pixels get higher
* coverage of filled-in outlines and are therefore `blacker'. This
* counteracts the `thinning out' of glyphs, making text remain readable
* at smaller sizes.
*
* By default, the Adobe engines for CFF, Type~1, and CID fonts darken
* stems at smaller sizes, regardless of hinting, to enhance contrast.
* Setting this property, stem darkening gets switched off.
*
* For the auto-hinter, stem-darkening is experimental currently and
* thus switched off by default (this is, `no-stem-darkening' is set to
* TRUE by default). Total consistency with the CFF driver is not
* achieved right now because the emboldening method differs and glyphs
* must be scaled down on the Y-axis to keep outline points inside their
* precomputed blue zones. The smaller the size (especially 9ppem and
* down), the higher the loss of emboldening versus the CFF driver.
*
* Note that stem darkening is never applied if @FT_LOAD_NO_SCALE is
* set.

* By default, the Adobe hinting engine, as used by the CFF, Type~1, and

* `no-stem-darkening' property isn't set):
*
* {
* stem width <= 0.5px: darkening amount = 0.4px
* stem width = 1px: darkening amount = 0.275px
* stem width = 1.667px: darkening amount = 0.275px
* stem width >= 2.333px: darkening amount = 0px
* }
*
* and piecewise linear in-between. At configuration time, these four
* control points can be set with the macro
* `CFF_CONFIG_OPTION_DARKENING_PARAMETERS'; the CFF, Type~1, and CID
* drivers share these values. At runtime, the control points can be
* changed using the `darkening-parameters' property, as the following

*
* 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). It is used in FreeType to select the `Infinality'
* subpixel hinting code. The code may be removed in a future
* version.
*
* TT_INTERPRETER_VERSION_40 ::
* Version~40 corresponds to MS rasterizer v.2.1; it is roughly
* equivalent to the hinting provided by DirectWrite ClearType (as can
* be found, for example, in Microsoft's Edge Browser on Windows~10).
* It is used in FreeType to select the `minimal' subpixel hinting
* code, a stripped-down and higher performance version of the
* `Infinality' code.
*
* @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 the configuration option
* TT_CONFIG_OPTION_SUBPIXEL_HINTING, selecting version~38 or~40 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).
*
* Keep in mind that the features of the above interpreter versions
* might not map exactly to FreeType features or behavior because it is
* a fundamentally different library with different internals.

* @description:
* Currently, three versions are available, two representing the

* one without, 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

* 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) tweaks in Microsoft's interpreter.
*
* Details on subpixel hinting and some of the necessary tweaks can be

* @description:

*
* The auto-hinter provides various script modules to hint glyphs.
* Examples of supported scripts are Latin or CJK. Before a glyph is
* auto-hinted, the Unicode character map of the font gets examined, and
* the script is then determined based on Unicode character ranges, see
* below.
*
* OpenType fonts, however, often provide much more glyphs than

* to be controlled by so-called `features'. Handling OpenType features
* can be quite complicated and thus needs a separate library on top of
* FreeType.
*
* The mapping between glyph indices and scripts (in the auto-hinter
* sense, see the @FT_AUTOHINTER_SCRIPT_XXX values) is stored as an
* array with `num_glyphs' elements, as found in the font's @FT_Face
* structure. The `glyph-to-script-map' property returns a pointer to
* this array, which can be modified as needed. Note that the
* modification should happen before the first glyph gets processed by

* @description:
* *Experimental* *only*
*
* If FreeType gets compiled with option AF_CONFIG_OPTION_USE_WARPER to
* activate the warp hinting code in the auto-hinter, this property
* switches warping on and off.
*
* Warping only works in `normal' auto-hinting mode replacing it.
* The idea of the code is to slightly scale and shift a glyph along
* the non-hinted dimension (which is usually the horizontal axis) so
* that as much of its segments are aligned (more or less) to the grid.
* To find out a glyph's optimal scaling and shifting value, various
* parameter combinations are tried and scored.
*
* By default, warping is off. The example below shows how to switch on
* warping (omitting the error handling).

* FT_Bool warping = 1;

* FT_Init_FreeType( &library );
*
* FT_Property_Set( library, "autofitter",
* "warping", &warping );
* }
*
* @note:
* This property can be used with @FT_Property_Get also.
*
* This property can be set via the `FREETYPE_PROPERTIES' environment
* variable (using values 1 and 0 for `on' and `off', respectively).
*
* The warping code can also change advance widths. Have a look at the
* `lsb_delta' and `rsb_delta' fields in the @FT_GlyphSlotRec structure
* for details on improving inter-glyph distances while rendering.
*
* Since warping is a global property of the auto-hinter it is best to
* change its value before rendering any face. Otherwise, you should
* reload all faces that get auto-hinted in `normal' hinting mode.

* 2.6

/* The header file `fterrors.h' (which is automatically included by */
/* `freetype.h' defines the handling of FreeType's enumeration */
/* constants. It can also be used to generate error message strings */
/* with a small macro trick explained below. */
/* */
/* *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, however). See the file */
/* `ftmoderr.h' for more details. */
/* */
/* *Error* *Message* *Strings* */
/* */
/* Error definitions are set up with special macros that allow client */
/* applications to build a table of error message strings. 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. */

/* numerical value, and `s' is the corresponding error string. */
/* */

*
* @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/Public 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 Poettgen <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
*
* https://msdn.microsoft.com/en-us/goglobal/bb964655,
*
* 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 superset of Arabic ISO 8859-6 (with different ordering).
*
* FT_WinFNT_ID_CP1257 ::
* A superset of Baltic ISO 8859-13 (with some deviations).
*
* FT_WinFNT_ID_CP1258 ::
* For Vietnamese. This encoding doesn't cover all necessary
* characters.
*
* FT_WinFNT_ID_CP1361 ::
* Korean (Johab).

* <Section>

*
* <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 an @FTC_FaceID into a new @FT_Face object. The latter is
* then completely managed by the cache, including its termination
* through @FT_Done_Face. To monitor termination of face objects, the
* finalizer callback in the `generic' field of the @FT_Face object can
* be used, which might also be used to store the @FTC_FaceID of the
* 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.

/* The face contains outline glyphs. Note that a face can contain */
/* bitmap strikes also, i.e., a face can have both this flag and */
/* @FT_FACE_FLAG_FIXED_SIZES set. */
/* */
/* FT_FACE_FLAG_FIXED_SIZES :: */
/* The face contains bitmap strikes. See also the */
/* `num_fixed_sizes' and `available_sizes' fields of @FT_FaceRec. */
/* */
/* FT_FACE_FLAG_FIXED_WIDTH :: */
/* The face contains fixed-width characters (like Courier, Lucida, */
/* MonoType, etc.). */
/* */
/* FT_FACE_FLAG_SFNT :: */
/* The face uses the SFNT storage scheme. For now, this means */
/* TrueType and OpenType. */
/* */
/* FT_FACE_FLAG_HORIZONTAL :: */
/* The face contains horizontal glyph metrics. This should be set */
/* for all common formats. */
/* */
/* FT_FACE_FLAG_VERTICAL :: */
/* The face contains vertical glyph metrics. This is only */
/* available in some formats, not all of them. */
/* */
/* FT_FACE_FLAG_KERNING :: */
/* The face contains kerning information. If set, the kerning */
/* distance can be retrieved using the function @FT_Get_Kerning. */
/* Otherwise the function always return the vector (0,0). Note */
/* that FreeType doesn't handle kerning data from the SFNT `GPOS' */
/* table (as present in many OpenType fonts). */
/* */
/* FT_FACE_FLAG_FAST_GLYPHS :: */
/* THIS FLAG IS DEPRECATED. DO NOT USE OR TEST IT. */
/* */
/* FT_FACE_FLAG_MULTIPLE_MASTERS :: */
/* The face contains multiple masters and is capable of */
/* interpolating between them. Supported formats are Adobe MM, */
/* TrueType GX, and OpenType variation fonts. */
/* */
/* See section @multiple_masters for API details. */
/* */
/* FT_FACE_FLAG_GLYPH_NAMES :: */
/* The face contains glyph names, which can be retrieved using */
/* @FT_Get_Glyph_Name. Note that some TrueType fonts contain */
/* broken glyph name tables. Use the function */
/* @FT_Has_PS_Glyph_Names when needed. */
/* */
/* FT_FACE_FLAG_EXTERNAL_STREAM :: */
/* Used internally by FreeType to indicate that a face's stream was */
/* provided by the client application and should not be destroyed */
/* when @FT_Done_Face is called. Don't read or test this flag. */
/* */
/* FT_FACE_FLAG_HINTER :: */
/* The font driver has a hinting machine of its own. For example, */
/* with TrueType fonts, it makes sense to use data from the SFNT */
/* `gasp' table only if the native TrueType hinting engine (with */
/* the bytecode interpreter) is available and active. */
/* */
/* FT_FACE_FLAG_CID_KEYED :: */
/* The face is CID-keyed. In that case, the face is not accessed */
/* by glyph indices but by CID values. For subsetted CID-keyed */
/* fonts this has the consequence that not all index values are a */
/* valid argument to @FT_Load_Glyph. Only the CID values for which */
/* corresponding glyphs in the subsetted font exist make */
/* `FT_Load_Glyph' return successfully; in all other cases you get */
/* an `FT_Err_Invalid_Argument' error. */
/* */
/* Note that CID-keyed fonts that are in an SFNT wrapper (this is, */
/* all OpenType/CFF fonts) don't have this flag set since the */
/* glyphs are accessed in the normal way (using contiguous */
/* indices); the `CID-ness' isn't visible to the application. */
/* */
/* FT_FACE_FLAG_TRICKY :: */
/* The face is `tricky', this is, it always needs the font format's */
/* native hinting engine to get a reasonable result. A typical */
/* example is the old Chinese font `mingli.ttf' (but not */
/* `mingliu.ttc') that uses TrueType bytecode instructions to move */
/* and scale all of its subglyphs. */
/* */
/* It is not possible to auto-hint such fonts using */
/* @FT_LOAD_FORCE_AUTOHINT; it will also ignore */
/* @FT_LOAD_NO_HINTING. You have to set both @FT_LOAD_NO_HINTING */
/* and @FT_LOAD_NO_AUTOHINT to really disable hinting; however, you */
/* probably never want this except for demonstration purposes. */
/* */
/* Currently, there are about a dozen TrueType fonts in the list of */

*
* @enum:
* FT_LOAD_XXX
*
* @description:
* A list of bit field constants for @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 for 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 loaded outline glyph but keep it in font units.
*
* This flag implies @FT_LOAD_NO_HINTING and @FT_LOAD_NO_BITMAP, and
* unsets @FT_LOAD_RENDER.
*
* If the font is `tricky' (see @FT_FACE_FLAG_TRICKY for more), using
* FT_LOAD_NO_SCALE usually yields meaningless outlines because the
* subglyphs must be scaled and positioned with hinting instructions.
* This can be solved by loading the font without FT_LOAD_NO_SCALE and
* setting the character size to `font->units_per_EM'.
*
* FT_LOAD_NO_HINTING ::
* Disable hinting. This generally generates `blurrier' bitmap glyphs
* when the glyph are 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. In particular, the
* `advance' value in the @FT_GlyphSlotRec structure is set to the
* `vertAdvance' value of the `metrics' field.
*
* In case @FT_HAS_VERTICAL doesn't return true, you shouldn't use
* this flag currently. Reason is that in this case vertical metrics
* get synthesized, and those values are not always consistent across
* various font formats.
*
* FT_LOAD_FORCE_AUTOHINT ::
* Prefer the auto-hinter over the font's native hinter. See also
* the note below.
*
* FT_LOAD_PEDANTIC ::
* Make the font driver 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.
*
* In particular, errors from the TrueType bytecode engine are not
* passed to the application if this flag is not set; this might
* result in partially hinted or distorted glyphs in case a glyph's
* bytecode is buggy.
*
* FT_LOAD_NO_RECURSE ::
* Don't load composite glyphs recursively. Instead, the font
* driver 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 subglyphs can
* then be accessed with @FT_Get_SubGlyph_Info.
*
* This flag implies @FT_LOAD_NO_SCALE and @FT_LOAD_IGNORE_TRANSFORM.
*
* FT_LOAD_IGNORE_TRANSFORM ::
* Ignore the transform matrix set by @FT_Set_Transform.
*
* 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 rather use @FT_LOAD_TARGET_MONO so that the
* monochrome-optimized hinting algorithm is used.
*
* FT_LOAD_LINEAR_DESIGN ::
* Keep `linearHoriAdvance' and `linearVertAdvance' fields of
* @FT_GlyphSlotRec in font units. See @FT_GlyphSlotRec for
* details.
*
* FT_LOAD_NO_AUTOHINT ::
* Disable the auto-hinter. See also the note below.
*
* FT_LOAD_COLOR ::
* [Since 2.5] Load embedded color bitmap images. The resulting color
* bitmaps, if available, will have the @FT_PIXEL_MODE_BGRA format.
* If the flag is not set and color bitmaps are found, they are
* converted to 256-level gray bitmaps transparently, using the
* @FT_PIXEL_MODE_GRAY format.
*
* FT_LOAD_COMPUTE_METRICS ::
* [Since 2.6.1] Compute glyph metrics from the glyph data, without
* the use of bundled metrics tables (for example, the `hdmx' table in
* TrueType fonts). This flag is mainly used by font validating or
* font editing applications, which need to ignore, verify, or edit
* those tables.
*
* Currently, this flag is only implemented for TrueType fonts.
*
* FT_LOAD_BITMAP_METRICS_ONLY ::
* [Since 2.7.1] Request loading of the metrics and bitmap image
* information of a (possibly embedded) bitmap glyph without
* allocating or copying the bitmap image data itself. No effect if
* the target glyph is not a bitmap image.
*
* This flag unsets @FT_LOAD_RENDER.
*
* FT_LOAD_CROP_BITMAP ::
* Ignored. Deprecated.
*
* FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH ::
* Ignored. Deprecated.
*
* @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.
*
* See the description of @FT_FACE_FLAG_TRICKY for a special exception
* (affecting only a handful of Asian fonts).
*
* Besides deciding which hinter to use, you can also decide which
* hinting algorithm to use. See @FT_LOAD_TARGET_XXX for details.
*
* Note that the auto-hinter needs a valid Unicode cmap (either a native
* one or synthesized by FreeType) for producing correct results. If a
* font provides an incorrect mapping (for example, assigning the
* character code U+005A, LATIN CAPITAL LETTER Z, to a glyph depicting a
* mathematical integral sign), the auto-hinter might produce useless
* results.

/**************************************************************************
*
* @enum:
* FT_LOAD_TARGET_XXX
*
* @description:
* A list of values to select a specific hinting algorithm for the
* hinter. You should OR one of these values to your `load_flags'
* when calling @FT_Load_Glyph.
*
* Note that a 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.
*
* @values:
* FT_LOAD_TARGET_NORMAL ::
* 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 gray-level modes. Many generated
* glyphs are fuzzier but better resemble their original shape. This
* is achieved by snapping glyphs to the pixel grid only vertically
* (Y-axis), as is done by FreeType's new CFF engine or Microsoft's
* ClearType font renderer. This preserves inter-glyph spacing in
* horizontal text. The snapping is done either by the native font
* driver, if the driver itself and the font support it, or by the
* auto-hinter.
*
* Advance widths are rounded to integer values; however, using the
* `lsb_delta' and `rsb_delta' fields of @FT_GlyphSlotRec, it is
* possible to get fractional advance widths for subpixel positioning
* (which is recommended to use).
*
* If configuration option AF_CONFIG_OPTION_TT_SIZE_METRICS is active,
* TrueType-like metrics are used to make this mode behave similarly
* as in unpatched FreeType versions between 2.4.6 and 2.7.1
* (inclusive).
*
* 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_LIGHT 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 that matches the used algorithm
* best). An exception is FT_LOAD_TARGET_MONO since it implies
* @FT_LOAD_MONOCHROME.
*
* 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 );
*
* FT_Render_Glyph( face->glyph, FT_RENDER_MODE_LCD );
* }
*
* In general, you should stick with one rendering mode. For example,
* switching between @FT_LOAD_TARGET_NORMAL and @FT_LOAD_TARGET_MONO
* enforces a lot of recomputation for TrueType fonts, which is slow.
* Another reason is caching: Selecting a different mode usually causes
* changes in both the outlines and the rasterized bitmaps; it is thus
* necessary to empty the cache after a mode switch to avoid false hits.

/* this does not translate to 50% brightness for that pixel on our */

/* dwell longer in the darks and only a pixel value of about 186 */
/* results in 50% brightness -- 128 ends up too dark on both bright */

/* Many characters, especially for CJK scripts, have variant forms. */
/* They are a sort of grey area somewhere between being totally */
/* irrelevant and semantically distinct; for this reason, the Unicode */
/* consortium decided to introduce Variation Sequences (VS), */
/* consisting of a Unicode base character and a variation selector */
/* instead of further extending the already huge number of */
/* characters. */
/* */
/* Unicode maintains two different sets, namely `Standardized */
/* Variation Sequences' and registered `Ideographic Variation */
/* Sequences' (IVS), collected in the `Ideographic Variation */
/* Database' (IVD). */
/* */
/* https://unicode.org/Public/UCD/latest/ucd/StandardizedVariants.txt */
/* https://unicode.org/reports/tr37/ */
/* https://unicode.org/ivd/ */
/* */
/* To date (January 2017), the character with the most ideographic */
/* variations is U+9089, having 32 such IVS. */
/* */
/* Three Mongolian Variation Selectors have the values U+180B-U+180D; */
/* 256 generic Variation Selectors are encoded in the ranges */
/* U+FE00-U+FE0F and U+E0100-U+E01EF. IVS currently use Variation */
/* Selectors from the range U+E0100-U+E01EF only. */
/* */
/* A VS consists of the base character value followed by a single */
/* Variation Selector. For example, to get the first variation of */
/* U+9089, you have to write the character sequence `U+9089 U+E0100'. */
/* */
/* Adobe and MS decided to support both standardized and ideographic */
/* VS with a new cmap subtable (format~14). It is an odd subtable */
/* because it is not a mapping of input code points to glyphs, but */
/* contains lists of all variations supported by the font. */
/* */
/* A variation may be either `default' or `non-default' for a given */

* @section:
* lcd_filtering
*
* @title:
* LCD Filtering
*
* @abstract:
* Reduce color fringes of subpixel-rendered bitmaps.
*
* @description:
* Should you #define FT_CONFIG_OPTION_SUBPIXEL_RENDERING in your
* `ftoption.h', which enables patented ClearType-style rendering,
* the LCD-optimized glyph bitmaps should be filtered to reduce color
* fringes inherent to this technology. The default FreeType LCD
* rendering uses different technology, and API described below,
* although available, does nothing.
*
* ClearType-style LCD rendering exploits the color-striped structure of
* LCD pixels, increasing the available resolution in the direction of
* the stripe (usually horizontal RGB) by a factor of~3. Since these
* subpixels are color pixels, using them unfiltered creates severe
* color fringes. Use the @FT_Library_SetLcdFilter API to specify a
* low-pass filter, which is then applied to subpixel-rendered bitmaps
* generated through @FT_Render_Glyph. The filter sacrifices some of
* the higher resolution to reduce color fringes, making the glyph image
* slightly blurrier. Positional improvements will remain.
*
* A filter should have two properties:
*
* 1) It should be normalized, meaning the sum of the 5~components
* should be 256 (0x100). It is possible to go above or under this
* target sum, however: going under means tossing out contrast, going
* over means invoking clamping and thereby non-linearities that
* increase contrast somewhat at the expense of greater distortion
* and color-fringing. Contrast is better enhanced through stem
* darkening.
*
* 2) It should be color-balanced, meaning a filter `{~a, b, c, b, a~}'
* where a~+ b~=~c. It distributes the computed coverage for one
* subpixel to all subpixels equally, sacrificing some won resolution
* but drastically reducing color-fringing. Positioning improvements
* remain! Note that color-fringing can only really be minimized
* when using a color-balanced filter and alpha-blending the glyph
* onto a surface in linear space; see @FT_Render_Glyph.
*
* Regarding the form, a filter can be a `boxy' filter or a `beveled'
* filter. Boxy filters are sharper but are less forgiving of non-ideal
* gamma curves of a screen (viewing angles!), beveled filters are
* fuzzier but more tolerant.
*
* Examples:
*
* - [0x10 0x40 0x70 0x40 0x10] is beveled and neither balanced nor
* normalized.
*
* - [0x1A 0x33 0x4D 0x33 0x1A] is beveled and balanced but not
* normalized.
*
* - [0x19 0x33 0x66 0x4c 0x19] is beveled and normalized but not
* balanced.
*
* - [0x00 0x4c 0x66 0x4c 0x00] is boxily beveled and normalized but not
* balanced.
*
* - [0x00 0x55 0x56 0x55 0x00] is boxy, normalized, and almost
* balanced.
*
* - [0x08 0x4D 0x56 0x4D 0x08] is beveled, normalized and, almost
* balanced.
*
* The filter affects glyph bitmaps rendered through @FT_Render_Glyph,
* @FT_Load_Glyph, and @FT_Load_Char. It does _not_ affect the output
* of @FT_Outline_Render and @FT_Outline_Get_Bitmap.
*
* If this feature is activated, the dimensions of LCD glyph bitmaps are
* either wider or taller than the dimensions of the corresponding
* outline with regard to the pixel grid. For example, for
* @FT_RENDER_MODE_LCD, the filter adds 3~subpixels to the left, and
* 3~subpixels to the right. The bitmap offset values are adjusted
* accordingly, so clients shouldn't need to modify their layout and
* glyph positioning code when enabling the filter.
*
* It is important to understand that linear alpha blending and gamma
* correction is critical for correctly rendering glyphs onto surfaces
* without artifacts and even more critical when subpixel rendering is
* involved.
*
* Each of the 3~alpha values (subpixels) is independently used to blend
* one color channel. That is, red alpha blends the red channel of the
* text color with the red channel of the background pixel. The
* distribution of density values by the color-balanced filter assumes
* alpha blending is done in linear space; only then color artifacts
* cancel out.

* of a slight blurriness in the output.
*
* It is a beveled, normalized, and color-balanced five-tap filter
* that is more forgiving to screens with non-ideal gamma curves and
* viewing angles. Note that while color-fringing is reduced, it can
* only be minimized by using linear alpha blending and gamma
* correction to render glyphs onto surfaces. The default filter
* weights are [0x08 0x4D 0x56 0x4D 0x08].
*
* FT_LCD_FILTER_LIGHT ::
* The light filter is a variant that is sharper at the cost of
* slightly more color fringes than the default one.
*
* It is a boxy, normalized, and color-balanced three-tap filter that
* is less forgiving to screens with non-ideal gamma curves and
* viewing angles. This filter works best when the rendering system
* uses linear alpha blending and gamma correction to render glyphs
* onto surfaces. The light filter weights are
* [0x00 0x55 0x56 0x55 0x00].
*
* FT_LCD_FILTER_LEGACY ::
* This filter corresponds to the original libXft color filter. It
* provides high contrast output but can exhibit really bad color
* fringes if glyphs are not extremely well hinted to the pixel grid.
* In other words, it only works well if the TrueType bytecode
* interpreter is enabled *and* high-quality hinted fonts are used.
*
* This filter is only provided for comparison purposes, and might be
* disabled or stay unsupported in the future.
*
* FT_LCD_FILTER_LEGACY1 ::
* For historical reasons, the FontConfig library returns a different
* enumeration value for legacy LCD filtering. To make code work that
* (incorrectly) forwards FontConfig's enumeration value to
* @FT_Library_SetLcdFilter without proper mapping, it is thus easiest
* to have another enumeration value, which is completely equal to
* `FT_LCD_FILTER_LEGACY'.
*
* @since:
* 2.3.0 (`FT_LCD_FILTER_LEGACY1' since 2.6.2)
