* @description:
* *Experimental* *only*
*
* 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
* character codes (small caps, superscripts, ligatures, swashes, etc.),
* 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

*
* 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 `light' hinting mode.

* cff_driver
*
* @title:
* The CFF driver
*
* @abstract:
* Controlling the CFF driver module.
*
* @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 list below gives the available properties
* together with the necessary macros and structures.
*
* The CFF driver's module name is `cff'.
*
* *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 sub-pixels 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 sub-pixels 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) Aligment 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.
*
* @order:
* hinting-engine
* no-stem-darkening
* darkening-parameters

/**************************************************************************

*
* @description:
* Thanks to Adobe, which contributed a new hinting (and parsing)
* engine, an application can select between `freetype' and `adobe' if
* compiled with CFF_CONFIG_OPTION_OLD_ENGINE. If this configuration
* macro isn't defined, `hinting-engine' does nothing.
*
* The default engine is `freetype' if CFF_CONFIG_OPTION_OLD_ENGINE is
* defined, and `adobe' otherwise.
*
* The following example code demonstrates how to select Adobe's hinting
* engine (omitting the error handling).
*
* {

*/
/**************************************************************************
*
* @property:
* darkening-parameters
*
* @description:
* By default, the Adobe CFF engine darkens stems as follows (if the
* `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'. At runtime, the control
* points can be changed using the `darkening-parameters' property, as
* the following example demonstrates.
*
* {
* FT_Library library;
* FT_Int darken_params[8] = { 500, 300, // x1, y1
* 1000, 200, // x2, y2
* 1500, 100, // x3, y3
* 2000, 0 }; // x4, y4
*
*
* FT_Init_FreeType( &library );
*
* FT_Property_Set( library, "cff",
* "darkening-parameters", darken_params );
* }
*
* The x~values give the stem width, and the y~values the darkening
* amount. The unit is 1000th of pixels. All coordinate values must be
* positive; the x~values must be monotonically increasing; the
* y~values must be monotonically decreasing and smaller than or
* equal to 500 (corresponding to half a pixel); the slope of each
* linear piece must be shallower than -1 (e.g., -.4).
*
* @note:
* This property can be used with @FT_Property_Get also.

/* */
/* This special header file is used to define the handling of FT2 */

/* 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). See the file `ftmoderr.h' for */
/* more details. */
/* */
/* */
/* 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__ */

*
* @title:
* LCD Filtering
*
* @abstract:
* Reduce color fringes of LCD-optimized bitmaps.
*
* @description:
* The @FT_Library_SetLcdFilter API can be used to specify a low-pass
* filter, which is then applied to LCD-optimized bitmaps generated
* through @FT_Render_Glyph. This is useful to reduce color fringes
* that would occur with unfiltered rendering.
*
* Note that no filter is active by default, and that this function is
* *not* implemented in default builds of the library. You need to
* #define FT_CONFIG_OPTION_SUBPIXEL_RENDERING in your `ftoption.h' file
* in order to activate it.
*
* FreeType generates alpha coverage maps, which are linear by nature.
* For instance, the value 0x80 in bitmap representation means that
* (within numerical precision) 0x80/0xFF fraction of that pixel is
* covered by the glyph's outline. The blending function for placing
* text over a background is
*
* {
* dst = alpha * src + (1 - alpha) * dst ,
* }
*
* which is known as OVER. However, when calculating the output of the
* OVER operator, the source colors should first be transformed to a
* linear color space, then alpha blended in that space, and transformed
* back to the output color space.
*
* When linear light blending is used, the default FIR5 filtering
* weights (as given by FT_LCD_FILTER_DEFAULT) are no longer optimal, as
* they have been designed for black on white rendering while lacking
* gamma correction. To preserve color neutrality, weights for a FIR5
* filter should be chosen according to two free parameters `a' and `c',
* and the FIR weights should be
*
* {
* [a - c, a + c, 2 * a, a + c, a - c] .
* }
*
* This formula generates equal weights for all the color primaries
* across the filter kernel, which makes it colorless. One suggested
* set of weights is
*
* {
* [0x10, 0x50, 0x60, 0x50, 0x10] ,
* }
*
* where `a' has value 0x30 and `b' value 0x20. The weights in filter
* may have a sum larger than 0x100, which increases coloration slightly
* but also improves contrast.

*
* FT_LCD_FILTER_LIGHT ::

* cost of slightly more color fringes than the default one. It might
* be better, depending on taste, your monitor, or your personal vision.
*
* FT_LCD_FILTER_LEGACY ::
* This filter corresponds to the original libXft color filter. It

*

* A handle to the target library instance.
*
* filter ::

* well on most LCD screens.
*
* @return:
* FreeType error code. 0~means success.
*
* @note:
* This feature is always disabled by default. Clients must make an
* explicit call to this function with a `filter' value other than
* @FT_LCD_FILTER_NONE in order to enable it.
*
* Due to *PATENTS* covering subpixel rendering, this function doesn't

* default builds of FreeType.
*
* The filter affects glyph bitmaps rendered through @FT_Render_Glyph,
* @FT_Outline_Get_Bitmap, @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 larger or taller than the dimensions of the corresponding
* outline with regards to the pixel grid. For example, for
* @FT_RENDER_MODE_LCD, the filter adds up to 3~pixels to the left, and

*
* FT_STROKER_LINEJOIN_MITER_FIXED ::
* Used to render mitered line joins, with fixed bevels if the
* miter limit is exceeded. The outer edges of the strokes
* for the two segments are extended until they meet at an
* angle. If the segments meet at too sharp an angle (such
* that the miter would extend from the intersection of the

* limit value and the border radius), then a bevel join (see

/**************************************************************************
*
* @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).
*
* {
* 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 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.

*
* @description:
* A list of valid values for the `charset' byte in

* 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 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
*
* 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 ::

/* 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. */

* 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.

/* Function calling conventions.
* =============================
* Normally it is not necessary to specify to the compiler how to call
* a function - it just does it - however on x86 systems derived from
* Microsoft and Borland C compilers ('IBM PC', 'DOS', 'Windows' systems
* and some others) there are multiple ways to call a function and the
* default can be changed on the compiler command line. For this reason
* libpng specifies the calling convention of every exported function and
* every function called via a user supplied function pointer. This is
* done in this file by defining the following macros:
*
* PNGAPI Calling convention for exported functions.
* PNGCBAPI Calling convention for user provided (callback) functions.
* PNGCAPI Calling convention used by the ANSI-C library (required
* for longjmp callbacks and sometimes used internally to
* specify the calling convention for zlib).
*
* These macros should never be overridden. If it is necessary to
* change calling convention in a private build this can be done
* by setting PNG_API_RULE (which defaults to 0) to one of the values
* below to select the correct 'API' variants.
*
* PNG_API_RULE=0 Use PNGCAPI - the 'C' calling convention - throughout.
* This is correct in every known environment.
* PNG_API_RULE=1 Use the operating system convention for PNGAPI and
* the 'C' calling convention (from PNGCAPI) for
* callbacks (PNGCBAPI). This is no longer required
* in any known environment - if it has to be used
* please post an explanation of the problem to the
* libpng mailing list.
*
* These cases only differ if the operating system does not use the C
* calling convention, at present this just means the above cases
* (x86 DOS/Windows sytems) and, even then, this does not apply to
* Cygwin running on those systems.
*
* Note that the value must be defined in pnglibconf.h so that what
* the application uses to call the library matches the conventions
* set when building the library.
*/
/* Symbol export
* =============
* When building a shared library it is almost always necessary to tell
* the compiler which symbols to export. The png.h macro 'PNG_EXPORT'
* is used to mark the symbols. On some systems these symbols can be
* extracted at link time and need no special processing by the compiler,
* on other systems the symbols are flagged by the compiler and just
* the declaration requires a special tag applied (unfortunately) in a
* compiler dependent way. Some systems can do either.
*
* A small number of older systems also require a symbol from a DLL to
* be flagged to the program that calls it. This is a problem because
* we do not know in the header file included by application code that
* the symbol will come from a shared library, as opposed to a statically
* linked one. For this reason the application must tell us by setting
* the magic flag PNG_USE_DLL to turn on the special processing before
* it includes png.h.
*
* Four additional macros are used to make this happen:
*
* PNG_IMPEXP The magic (if any) to cause a symbol to be exported from
* the build or imported if PNG_USE_DLL is set - compiler
* and system specific.
*
* PNG_EXPORT_TYPE(type) A macro that pre or appends PNG_IMPEXP to
* 'type', compiler specific.
*
* PNG_DLL_EXPORT Set to the magic to use during a libpng build to
* make a symbol exported from the DLL. Not used in the
* public header files; see pngpriv.h for how it is used
* in the libpng build.
*
* PNG_DLL_IMPORT Set to the magic to force the libpng symbols to come
* from a DLL - used to define PNG_IMPEXP when
* PNG_USE_DLL is set.
*/
/* System specific discovery.
* ==========================
* This code is used at build time to find PNG_IMPEXP, the API settings
* and PNG_EXPORT_TYPE(), it may also set a macro to indicate the DLL
* import processing is possible. On Windows systems it also sets
* compiler-specific macros to the values required to change the calling
* conventions of the various functions.
