|

* 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.

|
||||
* fonts render better than on Windows. A high amount of configurability

||||
* and flexibility, down to rules for single glyphs in fonts, but also

||||
* very slow. Its experimental and slow nature and the original
|
||||
* developer losing interest meant that this option was never enabled in

||||
* default builds.

*
|
||||
* The corresponding interpreter version is v38.
|
||||
*
|
||||
* Value 2:
|
||||
* The new default mode for the TrueType driver. The Infinality code
|
||||
* base was stripped to the bare minimum and all configurability removed
|
||||
* in the name of speed and simplicity. The configurability was mainly
|
||||
* aimed at legacy fonts like 'Arial', 'Times New Roman', or 'Courier'.
|
||||
* Legacy fonts are fonts that modify vertical stems to achieve clean
|
||||
* black-and-white bitmaps. The new mode focuses on applying a minimal
|
||||
* set of rules to all fonts indiscriminately so that modern and web
|
||||
* fonts render well while legacy fonts render okay.
|
||||
*
|
||||
* The corresponding interpreter version is v40.
|
||||
*
|
||||
* Value 3:
|
||||
* Compile both, making both v38 and v40 available (the latter is the
|
||||
* default).
|
||||
*
|
||||
* By undefining these, you get rendering behavior like on Windows without
|
||||
* ClearType, i.e., Windows XP without ClearType enabled and Win9x
|
||||
* (interpreter version v35). Or not, depending on how much hinting blood

* 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.
|
||||
*
|
||||
* ```
|
||||
* FT_ERROR_DEF( e, v, s )
|
||||
* ```
|
||||
*
|
||||
* This macro is called to define one single error. 'e' is the error
|
||||
* code identifier (e.g., `Invalid_Argument`), 'v' is the error's
|
||||
* numerical value, and '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, NULL } };
|
||||
*
|
||||
* const struct
|
||||
* {
|
||||
* int err_code;
|
||||
* const char* err_msg;
|
||||
* } ft_errors[] =
|
||||
*
|
||||
* #include FT_ERRORS_H
|
||||
* ```
|
||||
*
|
||||
* An alternative to using an array is a switch statement.
|
||||
*
|
||||
* ```
|
||||
* #undef FTERRORS_H_
|
||||
* #define FT_ERROR_START_LIST switch ( error_code ) {
|
||||
* #define FT_ERRORDEF( e, v, s ) case v: return s;
|
||||
* #define FT_ERROR_END_LIST }
|
||||
* ```
|
||||
*
|
||||
* If you use `FT_CONFIG_OPTION_USE_MODULE_ERRORS`, `error_code` should
|
||||
* be replaced with `FT_ERROR_BASE(error_code)` in the last example.

* Subpixel Rendering
|

|

* @abstract:
|
||||
* API to control subpixel rendering.
|
||||
*
|
||||
* @description:
|
||||
* FreeType provides two alternative subpixel rendering technologies.
|
||||
* Should you define `FT_CONFIG_OPTION_SUBPIXEL_RENDERING` in your
|
||||
* `ftoption.h` file, this enables patented ClearType-style rendering.
|
||||
* Otherwise, Harmony LCD rendering is enabled. These technologies are
|
||||
* controlled differently and API described below, although always
|
||||
* available, performs its function when appropriate method is enabled
|
||||
* and does nothing otherwise.
|
||||
*
|
||||
* 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. Using the
|
||||
* subpixels coverages unfiltered can create severe color fringes
|
||||
* especially when rendering thin features. Indeed, to produce
|
||||
* black-on-white text, the nearby color subpixels must be dimmed
|
||||
* equally.
|
||||
*
|
||||
* A good 5-tap FIR filter should be applied to subpixel coverages
|
||||
* regardless of pixel boundaries and should have these properties:
|
||||
*
|
||||
* 1. It should be symmetrical, like {~a, b, c, b, a~}, to avoid
|
||||
* any shifts in appearance.
|
||||
*
|
||||
* 2. It should be color-balanced, meaning a~+ b~=~c, to reduce color
|
||||
* fringes by distributing the computed coverage for one subpixel to
|
||||
* all subpixels equally.
|
||||
*
|
||||
* 3. It should be normalized, meaning 2a~+ 2b~+ c~=~1.0 to maintain
|
||||
* overall brightness.
|
||||
*
|
||||
* Boxy 3-tap filter {0, 1/3, 1/3, 1/3, 0} is sharper but is less
|
||||
* forgiving of non-ideal gamma curves of a screen (and viewing angles),
|
||||
* beveled filters are fuzzier but more tolerant.
|
||||
*
|
||||
* Use the @FT_Library_SetLcdFilter or @FT_Library_SetLcdFilterWeights
|
||||
* API to specify a low-pass filter, which is then applied to
|
||||
* subpixel-rendered bitmaps generated through @FT_Render_Glyph.
|
||||
*
|
||||
* Harmony LCD rendering is suitable to panels with any regular subpixel
|
||||
* structure, not just monitors with 3 color striped subpixels, as long
|
||||
* as the color subpixels have fixed positions relative to the pixel
|
||||
* center. In this case, each color channel is then rendered separately
|
||||
* after shifting the outline opposite to the subpixel shift so that the
|
||||
* coverage maps are aligned. This method is immune to color fringes
|
||||
* because the shifts do not change integral coverage.
|
||||
*
|
||||
* The subpixel geometry must be specified by xy-coordinates for each
|
||||
* subpixel. By convention they may come in the RGB order: {{-1/3, 0},
|
||||
* {0, 0}, {1/3, 0}} for standard RGB striped panel or {{-1/6, 1/4},
|
||||
* {-1/6, -1/4}, {1/3, 0}} for a certain PenTile panel.
|
||||
*
|
||||
* Use the @FT_Library_SetLcdGeometry API to specify subpixel positions.
|
||||
* If one follows the RGB order convention, the same order applies to the
|
||||
* resulting @FT_PIXEL_MODE_LCD and @FT_PIXEL_MODE_LCD_V bitmaps. Note,
|
||||
* however, that the coordinate frame for the latter must be rotated
|
||||
* clockwise. Harmony with default LCD geometry is equivalent to
|
||||
* ClearType with light filter.
|
||||
*
|
||||
* As a result of ClearType filtering or Harmony rendering, the
|
||||
* dimensions of LCD bitmaps can be 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 2~subpixels to
|
||||
* the left, and 2~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.
|
||||
*
|
||||
* The ClearType and Harmony rendering is applicable to glyph bitmaps
|
||||
* rendered through @FT_Render_Glyph, @FT_Load_Glyph, @FT_Load_Char, and
|
||||
* @FT_Glyph_To_Bitmap, when @FT_RENDER_MODE_LCD or @FT_RENDER_MODE_LCD_V
|
||||
* is specified. This API does not control @FT_Outline_Render and
|
||||
* @FT_Outline_Get_Bitmap.
|
||||
*
|
||||
* The described algorithms can completely remove color artefacts when
|
||||
* combined with gamma-corrected alpha blending in linear space. Each of
|
||||
* the 3~alpha values (subpixels) must by 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.

|

* This file is used to define the FreeType module error codes.
|
||||
*
|
||||
* If the macro `FT_CONFIG_OPTION_USE_MODULE_ERRORS` in `ftoption.h` is
|
||||
* set, the lower byte of an error value identifies the error code as
|
||||
* usual. In addition, the higher byte identifies the module. For
|
||||
* example, the error `FT_Err_Invalid_File_Format` has value 0x0003, the
|
||||
* error `TT_Err_Invalid_File_Format` has value 0x1303, the error
|
||||
* `T1_Err_Invalid_File_Format` has value 0x1403, etc.
|
||||
*
|
||||
* Note that `FT_Err_Ok`, `TT_Err_Ok`, etc. are always equal to zero,
|
||||
* including the high byte.
|
||||
*
|
||||
* If `FT_CONFIG_OPTION_USE_MODULE_ERRORS` isn't set, the higher byte of an
|
||||
* error value is set to zero.
|
||||
*
|
||||
* To hide the various `XXX_Err_` prefixes in the source code, FreeType
|
||||
* provides some macros in `fttypes.h`.
|
||||
*
|
||||
* FT_ERR( err )
|
||||
*
|
||||
* Add current error module prefix (as defined with the `FT_ERR_PREFIX`
|
||||
* macro) to `err`. For example, in the BDF module the line
|
||||
*
|
||||
* ```
|
||||
* error = FT_ERR( Invalid_Outline );
|
||||
* ```
|
||||
*
|
||||
* expands to
|
||||
*
|
||||
* ```
|
||||
* error = BDF_Err_Invalid_Outline;
|
||||
* ```
|
||||
*
|
||||
* For simplicity, you can always use `FT_Err_Ok` directly instead of
|
||||
* `FT_ERR( Ok )`.
|
||||
*
|
||||
* FT_ERR_EQ( errcode, err )
|
||||
* FT_ERR_NEQ( errcode, err )
|
||||
*
|
||||
* Compare error code `errcode` with the error `err` for equality and
|
||||
* inequality, respectively. Example:
|
||||
*
|
||||
* ```
|
||||
* if ( FT_ERR_EQ( error, Invalid_Outline ) )
|
||||
* ...
|
||||
* ```
|
||||
*
|
||||
* Using this macro you don't have to think about error prefixes. Of
|
||||
* course, if module errors are not active, the above example is the
|
||||
* same as
|
||||
*
|
||||
* ```
|
||||
* if ( error == FT_Err_Invalid_Outline )
|
||||
* ...
|

* FT_ERROR_BASE( errcode )
|

* FT_ERROR_MODULE( errcode )
|

|

|

|

*
|

* 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://docs.microsoft.com/en-us/windows/desktop/intl/code-page-identifiers
|
||||
* ,
|
||||
*
|
||||
* 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.

* @description:
|
||||
* 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.
|
||||
*
|
||||
* @since:

* 2.4.8

|

* *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
|
||||
* 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
|
||||
* the auto-hinter so that the global analysis of the font shapes
|
||||
* actually uses the modified mapping.
|
||||
*
|
||||
* The following example code demonstrates how to access it (omitting
|
||||
* the error handling).

*

|

*
|

* Warping only works in `light' auto-hinting mode. 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

|

* combinations are tried and scored.
|

*
|

* By default, warping is off. The example below shows how to switch on

|
||||
* for details on improving inter-glyph distances while rendering.
|

*
|

|

* alpha blending and gamma correction, glyphs will appear heavy and
|
||||
* 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. All glyphs that pass through the auto-hinter will
|
||||
* be emboldened unless this property is set to TRUE.
|
||||
*
|
||||
* See the description of the CFF driver for algorithmic details. Total
|
||||
* consistency with the CFF driver is currently not achieved 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 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.

/* <Description> */
|

/* 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 */
|

/* { */
|
||||
/* FT_ERROR_DEF( e, v, s ) */
|
||||
/* } */
|

/* */
|
||||
/* This macro is called to define one single error. `e' is the error */
|
||||
/* code identifier (e.g., `Invalid_Argument'), `v' is the error's */

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

|
||||
* LCD Filtering
|
||||
*
|
||||
* @abstract:
|
||||
* Reduce color fringes of subpixel-rendered bitmaps.
|
||||
*
|
||||
* @description:
|
||||
* Subpixel 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.
|
||||
*
|
||||
* 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 and explicitly call @FT_Library_SetLcdFilter
|
||||
* to enable it.
|
||||
*
|
||||
* 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

|
||||
* FT_LcdFilter
|
||||
*
|
||||
* @description:
|
||||
* A list of values to identify various types of LCD filters.
|
||||
*
|
||||
* @values:
|
||||
* FT_LCD_FILTER_NONE ::
|
||||
* Do not perform filtering. When used with subpixel rendering, this
|
||||
* results in sometimes severe color fringes.
|
||||
*
|
||||
* FT_LCD_FILTER_DEFAULT ::
|
||||
* The default filter reduces color fringes considerably, at the cost
|
||||
* 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)

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

* @property:
|

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

|

* 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.

|
||||
* }
|
||||
*
|
||||
* 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.

|

|
||||
* }
|
||||
*
|
||||
* 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.

* When querying for information about the character set of the font

|

* 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.

|

*
|

* @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,

|

|

*
|

* {
|

* FT_ULong length = 0;
|

*
|
||||
*
|

*
|
