- /* FT_FACE_FLAG_SCALABLE :: */
- /* 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, Lucido, */
- /* 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 the multiple-masters specific API for 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 */
- /* tricky fonts; they are hard-coded in file `ttobjs.c'. */

- *
- * @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 ::
- * 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 ::
- * 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 ::
- * 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 Microsoft's ClearType and Adobe's
- * proprietary 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.
- *
- * FT_LOAD_TARGET_MONO ::
- * Strong hinting algorithm that should only be used for monochrome
- * output. The result is probably unpleasant if the glyph is rendered
- * in non-monochrome modes.
- *
- * FT_LOAD_TARGET_LCD ::
- * A variant of @FT_LOAD_TARGET_NORMAL optimized for horizontally
- * decimated LCD displays.
- *
- * FT_LOAD_TARGET_LCD_V ::
- * A variant of @FT_LOAD_TARGET_NORMAL optimized for vertically
- * decimated LCD displays.
- *
- * @note:
- * You should use only _one_ of the FT_LOAD_TARGET_XXX values in your
- * `load_flags'. They can't be ORed.
- *
- * If @FT_LOAD_RENDER is also set, the glyph is rendered in the
- * corresponding mode (i.e., the mode 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 );

- * @section:
- * 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) 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.
- *
- * @order:
- * hinting-engine[cff]
- * no-stem-darkening[cff]
- * darkening-parameters[cff]

- * @property:

- *
- * @description:
- * By default, the Adobe CFF engine darkens stems as follows (if the

- *
- * {
- * 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

- *
- *
- * 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 property can be set via the `FREETYPE_PROPERTIES' environment
- * variable, using eight comma-separated integers without spaces. Here
- * the above example, using `\' to break the line for readability.
- *
- * {
- * FREETYPE_PROPERTIES=\

- /* Error Enumerations */
- /* */
- /* <Abstract> */
- /* How to handle errors and error strings. */
- /* */
- /* <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&nbsp;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&nbsp;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_ */

- * @section:

- *
- * @title:
- * 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
- * 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.

- * @enum:

- *
- * @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

- * @section:

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

- *
- * @property:
- * interpreter-version
- *
- * @description:
-
- * Currently, three versions are available, two representing the
- * bytecode interpreter with subpixel hinting support (old `Infinality'
- * code and new stripped-down and higher performance `minimal' code) and
- * 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
- * ClearType' is selected by the font). Microsoft's 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) tweaks in Microsoft's interpreter.
- *
- * 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'.
- * Note that FreeType currently doesn't really `subpixel hint' (6x1, 6x2,
- * or 6x5 supersampling) like discussed in the paper. Depending on the
- * chosen interpreter, it simply ignores instructions on vertical stems
- * to arrive at very similar results.
- *
- * The following example code demonstrates how to deactivate subpixel
- * hinting (omitting the error handling).
- *
- * {
- * FT_Library library;
- * FT_Face face;
- * FT_UInt interpreter_version = TT_INTERPRETER_VERSION_35;
- *
- *
- * FT_Init_FreeType( &library );
- *
- * FT_Property_Set( library, "truetype",
- * "interpreter-version",
- * &interpreter_version );
- * }
- *
- * @note:
- * This property can be used with @FT_Property_Get also.
- *
- * This property can be set via the `FREETYPE_PROPERTIES' environment
- * variable (using values `35', `38', or `40').
- */
-
-
- /**************************************************************************
- *
- * @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). 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
- * FT_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.

- /* */
- /* An automatic hinter might compute two kinds of data for a given face: */

- /* - global hints: Usually some metrics that describe global properties */
- /* of the face. It is computed by scanning more or less */
- /* aggressively the glyphs in the face, and thus can be */
- /* very slow to compute (even if the size of global */
- /* hints is really small). */
- /* */
- /* - glyph hints: These describe some important features of the glyph */
- /* outline, as well as how to align them. They are */
- /* generally much faster to compute than global hints. */
- /* */
- /* The current FreeType auto-hinter does a pretty good job while */
- /* performing fast computations for both global and glyph hints. */
- /* However, we might be interested in introducing more complex and */
- /* powerful algorithms in the future, like the one described in the John */
- /* D. Hobby paper, which unfortunately requires a lot more horsepower. */
- /* */
- /* Because a sufficiently sophisticated font management system would */
- /* typically implement an LRU cache of opened face objects to reduce */
- /* memory usage, it is a good idea to be able to avoid recomputing */
- /* global hints every time the same face is re-opened. */
- /* */
- /* We thus provide the ability to cache global hints outside of the face */
- /* object, in order to speed up font re-opening time. Of course, this */
- /* feature is purely optional, so most client programs won't even notice */
- /* it. */
- /* */
- /* I initially thought that it would be a good idea to cache the glyph */
- /* hints too. However, my general idea now is that if you really need */
- /* to cache these too, you are simply in need of a new font format, */

- *
- * key ::
- * An enumeration value representing the dictionary key to retrieve.
- *
- * idx ::
- * For array values, this specifies the index to be returned.

- * @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.

- *
- * TT_PLATFORM_MICROSOFT ::
- * Used by Microsoft to indicate Windows-specific charmaps. See
- * @TT_MS_ID_XXX for a list of corresponding `encoding_id' values.
- * Note that most fonts contain a Unicode charmap using
- * (TT_PLATFORM_MICROSOFT, @TT_MS_ID_UNICODE_CS).
- *
- * TT_PLATFORM_CUSTOM ::
- * Used to indicate application-specific charmaps.
- *
- * TT_PLATFORM_ADOBE ::
- * This value isn't part of any font format specification, but is used

- * carefully managed and preserved. However, it is convenient for us to
- * model our error mechanism on a Java-like exception mechanism.
- * When we assign an error code we are thus `throwing' an error.
- *
- * The perservation of an error code is done by coding convention.
- * Upon a function call if the error code is anything other than
- * `FT_Err_Ok', which is guaranteed to be zero, we
- * will return without altering that error. This will allow the

- /* A simple technical note on how the raster works */
- /* ----------------------------------------------- */
- /* */
- /* Converting an outline into a bitmap is achieved in several steps: */
- /* */
- /* 1 - Decomposing the outline into successive `profiles'. Each */
- /* profile is simply an array of scanline intersections on a given */
- /* dimension. A profile's main attributes are */
- /* */
- /* o its scanline position boundaries, i.e. `Ymin' and `Ymax' */
- /* */
- /* o an array of intersection coordinates for each scanline */
- /* between `Ymin' and `Ymax' */
- /* */
- /* o a direction, indicating whether it was built going `up' or */
- /* `down', as this is very important for filling rules */
- /* */
- /* o its drop-out mode */
- /* */
- /* 2 - Sweeping the target map's scanlines in order to compute segment */
- /* `spans' which are then filled. Additionally, this pass */
- /* performs drop-out control. */
- /* */
- /* The outline data is parsed during step 1 only. The profiles are */
- /* built from the bottom of the render pool, used as a stack. The */
- /* following graphics shows the profile list under construction: */
- /* */
- /* __________________________________________________________ _ _ */
- /* | | | | | */
- /* | profile | coordinates for | profile | coordinates for |--> */
- /* | 1 | profile 1 | 2 | profile 2 |--> */
- /* |_________|_________________|_________|_________________|__ _ _ */
- /* */
- /* ^ ^ */
- /* | | */
- /* start of render pool top */
- /* */
- /* The top of the profile stack is kept in the `top' variable. */
- /* */
- /* As you can see, a profile record is pushed on top of the render */
- /* pool, which is then followed by its coordinates/intersections. If */
- /* a change of direction is detected in the outline, a new profile is */
- /* generated until the end of the outline. */
- /* */
- /* Note that when all profiles have been generated, the function */
- /* Finalize_Profile_Table() is used to record, for each profile, its */
- /* bottom-most scanline as well as the scanline above its upmost */
- /* boundary. These positions are called `y-turns' because they (sort */
- /* of) correspond to local extrema. They are stored in a sorted list */
- /* built from the top of the render pool as a downwards stack: */
- /* */
- /* _ _ _______________________________________ */
- /* | | */
- /* <--| sorted list of | */
- /* <--| extrema scanlines | */
- /* _ _ __________________|____________________| */
- /* */
- /* ^ ^ */
- /* | | */
- /* maxBuff sizeBuff = end of pool */
- /* */
- /* This list is later used during the sweep phase in order to */
- /* optimize performance (see technical note on the sweep below). */
- /* */
- /* Of course, the raster detects whether the two stacks collide and */
- /* handles the situation properly. */

- /* This is a new anti-aliasing scan-converter for FreeType 2. The */

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

- * Calculate the phantom points
- *
- * Defining the right side bearing (rsb) as
- *
- * rsb = aw - (lsb + xmax - xmin)
- *
- * (with `aw' the advance width, `lsb' the left side bearing, and `xmin'
- * and `xmax' the glyph's minimum and maximum x value), the OpenType
- * specification defines the initial position of horizontal phantom points
- * as
- *
- * pp1 = (round(xmin - lsb), 0) ,
- * pp2 = (round(pp1 + aw), 0) .
- *
- * Note that the rounding to the grid (in the device space) is not
- * documented currently in the specification.
- *
- * However, the specification lacks the precise definition of vertical
- * phantom points. Greg Hitchcock provided the following explanation.
- *
- * - a `vmtx' table is present
- *
- * For any glyph, the minimum and maximum y values (`ymin' and `ymax')
- * are given in the `glyf' table, the top side bearing (tsb) and advance
- * height (ah) are given in the `vmtx' table. The bottom side bearing
- * (bsb) is then calculated as
- *
- * bsb = ah - (tsb + ymax - ymin) ,
- *
- * and the initial position of vertical phantom points is
- *
- * pp3 = (x, round(ymax + tsb)) ,
- * pp4 = (x, round(pp3 - ah)) .
- *
- * See below for value `x'.
- *
- * - no `vmtx' table in the font
- *
- * If there is an `OS/2' table, we set
- *
- * DefaultAscender = sTypoAscender ,
- * DefaultDescender = sTypoDescender ,
- *
- * otherwise we use data from the `hhea' table:
- *
- * DefaultAscender = Ascender ,
- * DefaultDescender = Descender .
- *
- * With these two variables we can now set
- *
- * ah = DefaultAscender - sDefaultDescender ,
- * tsb = DefaultAscender - yMax ,
- *
- * and proceed as if a `vmtx' table was present.
- *
- * Usually we have
- *
- * x = aw / 2 , (1)
- *
- * but there is one compatibility case where it can be set to
- *
- * x = -DefaultDescender -
- * ((DefaultAscender - DefaultDescender - aw) / 2) . (2)
- *
- * and another one with
- *
- * x = 0 . (3)
- *
- * In Windows, the history of those values is quite complicated,
- * depending on the hinting engine (that is, the graphics framework).
- *
- * framework from to formula
- * ----------------------------------------------------------
- * GDI Windows 98 current (1)
- * (Windows 2000 for NT)
- * GDI+ Windows XP Windows 7 (2)
- * GDI+ Windows 8 current (3)
- * DWrite Windows 7 current (3)
- *
- * For simplicity, FreeType uses (1) for grayscale subpixel hinting and

- /*
- * Modern TrueType fonts are usually rendered through Microsoft's
- * collection of rendering techniques called ClearType (e.g., subpixel
- * rendering and subpixel hinting). When ClearType was introduced, most
- * fonts were not ready. Microsoft decided to implement a backwards
- * compatibility mode that employed several simple to complicated
- * assumptions and tricks that modified the interpretation of the
- * bytecode contained in these fonts to make them look ClearType-y
- * somehow. Most (web)fonts that were released since then have come to
- * rely on these hacks to render correctly, even some of Microsoft's
- * flagship ClearType fonts (Calibri, Cambria, Segoe UI).
- *
- * The minimal subpixel hinting code (interpreter version 40) employs a
- * small list of font-agnostic hacks to bludgeon non-native-ClearType
- * fonts (except tricky ones[1]) into submission. It will not try to
- * toggle hacks for specific fonts for performance and complexity
- * reasons. The focus is on modern (web)fonts rather than legacy fonts
- * that were made for black-and-white rendering.
- *
- * Major hacks
- *
- * - Any point movement on the x axis is ignored (cf. `Direct_Move' and
- * `Direct_Move_X'). This has the smallest code footprint and single
- * biggest effect. The ClearType way to increase resolution is
- * supersampling the x axis, the FreeType way is ignoring instructions
- * on the x axis, which gives the same result in the majority of
- * cases.
- *
- * - Points are not moved post-IUP (neither on the x nor on the y axis),
- * except the x component of diagonal moves post-IUP (cf.
- * `Direct_Move', `Direct_Move_Y', `Move_Zp2_Point'). Post-IUP
- * changes are commonly used to `fix' pixel patterns which has little
- * use outside monochrome rendering.
- *
- * - SHPIX and DELTAP don't execute unless moving a composite on the
- * y axis or moving a previously y touched point. SHPIX additionally
- * denies movement on the x axis (cf. `Ins_SHPIX' and `Ins_DELTAP').
- * Both instructions are commonly used to `fix' pixel patterns for
- * monochrome or Windows's GDI rendering but make little sense for
- * FreeType rendering. Both can distort the outline. See [2] for
- * details.
- *
- * - The hdmx table and modifications to phantom points are ignored.
- * Bearings and advance widths remain unchanged (except rounding them
- * outside the interpreter!), cf. `compute_glyph_metrics' and
- * `TT_Hint_Glyph'. Letting non-native-ClearType fonts modify spacing
- * might mess up spacing.
- *
- * Minor hacks
- *
- * - FLIPRGON, FLIPRGOFF, and FLIPPT don't execute post-IUP. This
- * prevents dents in e.g. Arial-Regular's `D' and `G' glyphs at
- * various sizes.
- *
- * (Post-IUP is the state after both IUP[x] and IUP[y] have been
- * executed.)
- *
- * The best results are achieved for fonts that were from the outset
- * designed with ClearType in mind, meaning they leave the x axis mostly
- * alone and don't mess with the `final' outline to produce more
- * pleasing pixel patterns. The harder the designer tried to produce
- * very specific patterns (`superhinting') for pre-ClearType-displays,
- * the worse the results.
- *
- * Microsoft defines a way to turn off backwards compatibility and
- * interpret instructions as before (called `native ClearType')[2][3].
- * The font designer then regains full control and is responsible for
- * making the font work correctly with ClearType without any
- * hand-holding by the interpreter or rasterizer[4]. The v40
- * interpreter assumes backwards compatibility by default, which can be
- * turned off the same way by executing the following in the control
- * program (cf. `Ins_INSTCTRL').
- *
- * #PUSH 4,3
- * INSTCTRL[]
- *
- * [1] Tricky fonts as FreeType defines them rely on the bytecode
- * interpreter to display correctly. Hacks can interfere with them,
- * so they get treated like native ClearType fonts (v40 with
- * backwards compatibility turned off). Cf. `TT_RunIns'.
- *
- * [2] Proposed by Microsoft's Greg Hitchcock in
- * https://www.microsoft.com/typography/cleartype/truetypecleartype.aspx
- *
- * [3] Beat Stamm describes it in more detail:
- * http://www.beatstamm.com/typography/RTRCh4.htm#Sec12
- *
- * [4] The list of `native ClearType' fonts is small at the time of this
- * writing; I found the following on a Windows 10 Update 1511
- * installation: Constantia, Corbel, Sitka, Malgun Gothic, Microsoft
- * JhengHei (Bold and UI Bold), Microsoft YaHei (Bold and UI Bold),
- * SimSun, NSimSun, and Yu Gothic.

- /* This is the new and improved Type 1 data loader for FreeType 2. The */

- /* maintain, and contains incredible hacks to make it accept some */
- /* ill-formed Type 1 fonts without hiccup-ing. Moreover, about 5% of */
- /* the Type 1 fonts on my machine still aren't loaded correctly by it. */
- /* */
- /* This version is much simpler, much faster and also easier to read and */
- /* maintain by a great order of magnitude. The idea behind it is to */
- /* _not_ try to read the Type 1 token stream with a state machine (i.e. */
- /* a Postscript-like interpreter) but rather to perform simple pattern */
- /* matching. */
- /* */
- /* Indeed, nearly all data definitions follow a simple pattern like */
- /* */
- /* ... /Field <data> ... */
- /* */
- /* where <data> can be a number, a boolean, a string, or an array of */
- /* numbers. There are a few exceptions, namely the encoding, font name, */
- /* charstrings, and subrs; they are handled with a special pattern */
- /* matching routine. */
- /* */
- /* All other common cases are handled very simply. The matching rules */
- /* are defined in the file `t1tokens.h' through the use of several */
- /* macros calls PARSE_XXX. This file is included twice here; the first */
- /* time to generate parsing callback functions, the second time to */
- /* generate a table of keywords (with pointers to the associated */
- /* callback functions). */
- /* */
- /* The function `parse_dict' simply scans *linearly* a given dictionary */
- /* (either the top-level or private one) and calls the appropriate */
- /* callback when it encounters an immediate keyword. */
- /* */
- /* This is by far the fastest way one can find to parse and read all */
- /* data. */
- /* */
- /* This led to tremendous code size reduction. Note that later, the */
- /* glyph loader will also be _greatly_ simplified, and the automatic */
- /* hinter will replace the clumsy `t1hinter'. */
