In this case, the following happens: - * - * 1. FreeType looks for a bitmap for the glyph corresponding to the - * face's current size. If one is found, the function returns. - * The bitmap data can be accessed from the glyph slot (see note - * below). - * - * 2. If no embedded bitmap is searched or found, FreeType looks for a - * scalable outline. If one is found, it is loaded from the font - * file, scaled to device pixels, then `hinted' to the pixel grid - * in order to optimize it. The outline data can be accessed from - * the glyph slot (see note below). - * - * Note that by default, the glyph loader doesn't render outlines into - * bitmaps. The following flags are used to modify this default - * behaviour to more specific and useful cases. - * - * FT_LOAD_NO_SCALE :: - * Don't scale the 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 :: - * Indicates that the auto-hinter is preferred over the font's native - * hinter. See also the note below. - * - * FT_LOAD_CROP_BITMAP :: - * Indicates that the font driver should crop the loaded bitmap glyph - * (i.e., remove all space around its black bits). Not all drivers - * implement this. - * - * FT_LOAD_PEDANTIC :: - * Indicates that the font driver should perform pedantic verifications - * during glyph loading. This is mostly used to detect broken glyphs - * in fonts. By default, FreeType tries to handle broken fonts also. - * - * 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_IGNORE_GLOBAL_ADVANCE_WIDTH :: - * Ignored. Deprecated. - * - * FT_LOAD_NO_RECURSE :: - * This flag is only used internally. It merely indicates that the - * font driver should not load composite glyphs recursively. Instead, - * it should set the `num_subglyph' and `subglyphs' values of the - * glyph slot accordingly, and set `glyph->format' to - * @FT_GLYPH_FORMAT_COMPOSITE. - * - * The description of sub-glyphs is not available to client - * applications for now. - * - * This flag implies @FT_LOAD_NO_SCALE and @FT_LOAD_IGNORE_TRANSFORM. - * - * FT_LOAD_IGNORE_TRANSFORM :: - * Indicates that the transform matrix set by @FT_Set_Transform should - * be ignored. - * - * FT_LOAD_MONOCHROME :: - * This flag is used with @FT_LOAD_RENDER to indicate that you want to - * render an outline glyph to a 1-bit monochrome bitmap glyph, with - * 8~pixels packed into each byte of the bitmap data. - * - * Note that this has no effect on the hinting algorithm used. You - * should rather use @FT_LOAD_TARGET_MONO so that the - * monochrome-optimized hinting algorithm is used. - * - * FT_LOAD_LINEAR_DESIGN :: - * Indicates that the `linearHoriAdvance' and `linearVertAdvance' - * fields of @FT_GlyphSlotRec should be kept in font units. See - * @FT_GlyphSlotRec for details. - * - * FT_LOAD_NO_AUTOHINT :: - * Disable auto-hinter. See also the note below. - * - * FT_LOAD_COLOR :: - * This flag is used to request loading of color embedded-bitmap - * images. The resulting color bitmaps, if available, will have the - * @FT_PIXEL_MODE_BGRA format. When the flag is not used and color - * bitmaps are found, they will be converted to 256-level gray - * bitmaps transparently. Those bitmaps will be in the - * @FT_PIXEL_MODE_GRAY format. - * - * @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. - * - */ -#define FT_LOAD_DEFAULT 0x0 -#define FT_LOAD_NO_SCALE ( 1L << 0 ) -#define FT_LOAD_NO_HINTING ( 1L << 1 ) -#define FT_LOAD_RENDER ( 1L << 2 ) -#define FT_LOAD_NO_BITMAP ( 1L << 3 ) -#define FT_LOAD_VERTICAL_LAYOUT ( 1L << 4 ) -#define FT_LOAD_FORCE_AUTOHINT ( 1L << 5 ) -#define FT_LOAD_CROP_BITMAP ( 1L << 6 ) -#define FT_LOAD_PEDANTIC ( 1L << 7 ) -#define FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH ( 1L << 9 ) -#define FT_LOAD_NO_RECURSE ( 1L << 10 ) -#define FT_LOAD_IGNORE_TRANSFORM ( 1L << 11 ) -#define FT_LOAD_MONOCHROME ( 1L << 12 ) -#define FT_LOAD_LINEAR_DESIGN ( 1L << 13 ) -#define FT_LOAD_NO_AUTOHINT ( 1L << 15 ) - /* Bits 16..19 are used by `FT_LOAD_TARGET_' */ -#define FT_LOAD_COLOR ( 1L << 20 ) - - /* */ - - /* used internally only by certain font drivers! */ -#define FT_LOAD_ADVANCE_ONLY ( 1L << 8 ) -#define FT_LOAD_SBITS_ONLY ( 1L << 14 ) - - - /************************************************************************** - * - * @enum: - * FT_LOAD_TARGET_XXX - * - * @description: - * A list of values that are used to select a specific hinting algorithm - * to use by the hinter.

See the @FT_Generic type + * description. + * + * bbox :: + * The font bounding box. Coordinates are expressed in font units (see + * `units_per_EM`). The box is large enough to contain any glyph from + * the font. Thus, `bbox.yMax` can be seen as the 'maximum ascender', + * and `bbox.yMin` as the 'minimum descender'.

See also the `num_fixed_sizes` + * and `available_sizes` fields of @FT_FaceRec. + * + * FT_FACE_FLAG_FIXED_WIDTH :: + * The face contains fixed-width characters (like Courier, Lucida, + * MonoType, etc.). + * + * FT_FACE_FLAG_SFNT :: + * The face uses the SFNT storage scheme. For now, this means TrueType + * and OpenType. + * + * FT_FACE_FLAG_HORIZONTAL :: + * The face contains horizontal glyph metrics. This should be set for + * all common formats. + * + * FT_FACE_FLAG_VERTICAL :: + * The face contains vertical glyph metrics.

If set, the kerning distance + * can be retrieved using the function @FT_Get_Kerning. Otherwise the + * function always returns the vector (0,0). + * + * Note that for TrueType fonts only, FreeType supports both the 'kern' + * table and the basic, pair-wise kerning feature from the 'GPOS' table + * (with `TT_CONFIG_OPTION_GPOS_KERNING` enabled), though FreeType does + * not support the more advanced GPOS layout features; use a library + * like HarfBuzz for those instead. + * + * FT_FACE_FLAG_FAST_GLYPHS :: + * THIS FLAG IS DEPRECATED. DO NOT USE OR TEST IT. + * + * FT_FACE_FLAG_MULTIPLE_MASTERS :: + * The face contains multiple masters and is capable of interpolating + * between them. Supported formats are Adobe MM, TrueType GX, and + * OpenType variation fonts. + * + * See section @multiple_masters for API details. + * + * FT_FACE_FLAG_GLYPH_NAMES :: + * The face contains glyph names, which can be retrieved using + * @FT_Get_Glyph_Name. Note that some TrueType fonts contain broken + * glyph name tables. Use the function @FT_Has_PS_Glyph_Names when + * needed. + * + * FT_FACE_FLAG_EXTERNAL_STREAM :: + * Used internally by FreeType to indicate that a face's stream was + * provided by the client application and should not be destroyed when + * @FT_Done_Face is called. Don't read or test this flag. + * + * FT_FACE_FLAG_HINTER :: + * The font driver has a hinting machine of its own. For example, with + * TrueType fonts, it makes sense to use data from the SFNT 'gasp' + * table only if the native TrueType hinting engine (with the bytecode + * interpreter) is available and active. + * + * FT_FACE_FLAG_CID_KEYED :: + * The face is CID-keyed. In that case, the face is not accessed by + * glyph indices but by CID values. For subsetted CID-keyed fonts this + * has the consequence that not all index values are a valid argument + * to @FT_Load_Glyph. Only the CID values for which corresponding + * glyphs in the subsetted font exist make `FT_Load_Glyph` return + * successfully; in all other cases you get an + * `FT_Err_Invalid_Argument` error. + * + * Note that CID-keyed fonts that are in an SFNT wrapper (that 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', that 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`. + * + * FT_FACE_FLAG_COLOR :: + * [Since 2.5.1] The face has color glyph tables.

If the flag is not set and color bitmaps are found, + * they are converted to 256-level gray bitmaps, using the + * @FT_PIXEL_MODE_GRAY format. + * + * [Since 2.12] If the glyph index maps to an entry in the face's + * 'SVG~' table, load the associated SVG document from this table and + * set the `format` field of @FT_GlyphSlotRec to @FT_GLYPH_FORMAT_SVG + * ([since 2.13.1] provided @FT_LOAD_NO_SVG is not set). Note that + * FreeType itself can't render SVG documents; however, the library + * provides hooks to seamlessly integrate an external renderer. See + * sections @ot_svg_driver and @svg_fonts for more. + * + * [Since 2.10, experimental] If the glyph index maps to an entry in + * the face's 'COLR' table with a 'CPAL' palette table (as defined in + * the OpenType specification), make @FT_Render_Glyph provide a default + * blending of the color glyph layers associated with the glyph index, + * using the same bitmap format as embedded color bitmap images.

Therefore, + * it requires the following. + * + * * @FTC_FaceID, an arbitrary non-zero value that uniquely identifies + * available or installed font faces, has to be provided to the + * cache by the client. Note that the cache only stores and compares + * these values and doesn't try to interpret them in any way, but they + * have to be persistent on the client side. + * + * * @FTC_Face_Requester, a method to convert an @FTC_FaceID into a new + * @FT_Face object when necessary, has to be provided to the cache by + * the client. The @FT_Face object is completely managed by the cache, + * including its termination through @FT_Done_Face. To monitor + * termination of face objects, the finalizer callback in the `generic` + * field of the @FT_Face object can be used, which might also be used + * to store the @FTC_FaceID of the face. + * + * Clients are free to map face IDs to anything useful. The most simple + * usage is, for example, to associate them to a `{pathname,face_index}` + * pair that is then used by @FTC_Face_Requester to call @FT_New_Face. + * However, more complex schemes are also possible. + * + * Note that for the cache to work correctly, the face ID values must be + * **persistent**, which means that the contents they point to should not + * change at runtime, or that their value should not become invalid. + * If this is unavoidable (e.g., when a font is uninstalled at runtime), + * you should call @FTC_Manager_RemoveFaceID as soon as possible to let + * the cache get rid of any references to the old @FTC_FaceID it may keep + * internally. Failure to do so will lead to incorrect behaviour or even + * crashes in @FTC_Face_Requester. + * + * To use the cache, start with calling @FTC_Manager_New to create a new + * @FTC_Manager object, which models a single cache instance. You can + * then look up @FT_Face and @FT_Size objects with + * @FTC_Manager_LookupFace and @FTC_Manager_LookupSize, respectively, and + * use them in any FreeType work stream. You can also cache other + * FreeType objects as follows. + * + * * If you want to use the charmap caching, call @FTC_CMapCache_New, + * then later use @FTC_CMapCache_Lookup to perform the equivalent of + * @FT_Get_Char_Index, only much faster. + * + * * If you want to use the @FT_Glyph caching, call @FTC_ImageCache_New, + * then later use @FTC_ImageCache_Lookup to retrieve the corresponding + * @FT_Glyph objects from the cache. + * + * * If you need lots of small bitmaps, it is much more memory-efficient + * to call @FTC_SBitCache_New followed by @FTC_SBitCache_Lookup.

Sometimes the + * vertical stems may be only partially black. In this context, + * 'anti-aliasing' 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 anti-aliasing for LCD + * screens: The pixel geometry of modern displays supplies three vertical + * subpixels as the eye moves horizontally across each visible pixel. On + * devices where we can be certain this characteristic is present a + * rasterizer can take advantage of the subpixels to add increments of + * weight. In Western writing systems this turns out to be the more + * critical direction anyway; the weights and spacing of vertical stems + * (see above) are central to Armenian, Cyrillic, Greek, and Latin type + * designs. Even when the rasterizer uses greyscale anti-aliasing 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 (that 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. + * + */ + + + /************************************************************************** + * + * @section: + * pcf_driver + * + * @title: + * The PCF driver + * + * @abstract: + * Controlling the PCF driver module. + * + * @description: + * While FreeType's PCF driver doesn't expose API functions by itself, it + * is possible to control its behaviour with @FT_Property_Set and + * @FT_Property_Get.

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://rastertragedy.com/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://rastertragedy.com/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://rastertragedy.com/RTRCh4.htm#Sec22. Note that the + * TrueType interpreter fully allows the advance width to be adjusted in + * this mode, just the DWrite client will ignore those changes. + * + * _ClearType Backward Compatibility_ + * + * This is a set of exceptions made in the TrueType interpreter to + * minimize hinting techniques that were problematic with the extra + * resolution of ClearType; see + * http://rastertragedy.com/RTRCh4.htm#Sec1 and + * https://www.microsoft.com/typography/cleartype/truetypecleartype.aspx. + * This technique is not to be confused with ClearType compatible widths. + * ClearType backward compatibility has no direct impact on changing + * advance widths, but there might be an indirect impact on disabling + * some deltas. This could be worked around in backward compatibility + * mode. + * + * _Native ClearType Mode_ + * + * (Not to be confused with 'natural widths'.) This mode removes all the + * exceptions in the TrueType interpreter when running with ClearType. + * Any issues on widths would still apply, though. + * + */ + + + /************************************************************************** + * + * @section: + * ot_svg_driver + * + * @title: + * The SVG driver + * + * @abstract: + * Controlling the external rendering of OT-SVG glyphs. + * + * @description: + * By default, FreeType can only load the 'SVG~' table of OpenType fonts + * if configuration macro `FT_CONFIG_OPTION_SVG` is defined.

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. + * + */ +#define TT_INTERPRETER_VERSION_35 35 +#define TT_INTERPRETER_VERSION_38 38 +#define TT_INTERPRETER_VERSION_40 40 + + + /************************************************************************** + * + * @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 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.

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 + * subpixel 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 + * evenly. Therefore, an equalizing 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 can be 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 shifts, the resulting + * dimensions of LCD bitmaps can be slightly wider or taller than the + * dimensions the original 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.

This implies - * the following scheme: - * - * First, available or installed font faces are uniquely identified by - * @FTC_FaceID values, provided to the cache by the client. Note that - * the cache only stores and compares these values, and doesn't try to - * interpret them in any way. - * - * Second, the cache calls, only when needed, a client-provided function - * to convert an @FTC_FaceID into a new @FT_Face object. The latter is - * then completely managed by the cache, including its termination - * through @FT_Done_Face. To monitor termination of face objects, the - * finalizer callback in the `generic' field of the @FT_Face object can - * be used, which might also be used to store the @FTC_FaceID of the - * face. - * - * Clients are free to map face IDs to anything else. The most simple - * usage is to associate them to a (pathname,face_index) pair that is - * used to call @FT_New_Face. However, more complex schemes are also - * possible. - * - * Note that for the cache to work correctly, the face ID values must be - * *persistent*, which means that the contents they point to should not - * change at runtime, or that their value should not become invalid. - * - * If this is unavoidable (e.g., when a font is uninstalled at runtime), - * you should call @FTC_Manager_RemoveFaceID as soon as possible, to let - * the cache get rid of any references to the old @FTC_FaceID it may - * keep internally. Failure to do so will lead to incorrect behaviour - * or even crashes. - * - * To use the cache, start with calling @FTC_Manager_New to create a new - * @FTC_Manager object, which models a single cache instance. You can - * then look up @FT_Face and @FT_Size objects with - * @FTC_Manager_LookupFace and @FTC_Manager_LookupSize, respectively. - * - * If you want to use the charmap caching, call @FTC_CMapCache_New, then - * later use @FTC_CMapCache_Lookup to perform the equivalent of - * @FT_Get_Char_Index, only much faster. - * - * If you want to use the @FT_Glyph caching, call @FTC_ImageCache, then - * later use @FTC_ImageCache_Lookup to retrieve the corresponding - * @FT_Glyph objects from the cache. - * - * If you need lots of small bitmaps, it is much more memory efficient - * to call @FTC_SBitCache_New followed by @FTC_SBitCache_Lookup. This - * returns @FTC_SBitRec structures, which are used to store small - * bitmaps directly. (A small bitmap is one whose metrics and - * dimensions all fit into 8-bit integers). - * - * We hope to also provide a kerning cache in the near future. - * - * - * <Order> - * FTC_Manager - * FTC_FaceID - * FTC_Face_Requester - * - * FTC_Manager_New - * FTC_Manager_Reset - * FTC_Manager_Done - * FTC_Manager_LookupFace - * FTC_Manager_LookupSize - * FTC_Manager_RemoveFaceID - * - * FTC_Node - * FTC_Node_Unref - * - * FTC_ImageCache - * FTC_ImageCache_New - * FTC_ImageCache_Lookup - * - * FTC_SBit - * FTC_SBitCache - * FTC_SBitCache_New - * FTC_SBitCache_Lookup - * - * FTC_CMapCache - * FTC_CMapCache_New - * FTC_CMapCache_Lookup - * - *************************************************************************/ - - - /*************************************************************************/ - /*************************************************************************/ - /*************************************************************************/ - /***** *****/ - /***** BASIC TYPE DEFINITIONS *****/ - /***** *****/ - /*************************************************************************/ - /*************************************************************************/ - /*************************************************************************/ - - - /************************************************************************* - * - * @type: FTC_FaceID - * - * @description: - * An opaque pointer type that is used to identity face objects.

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

`afstyles.h'. +// +// The AF_BLUE_PROPERTY_XXX flags are defined in `afblue.h'; here some +// explanations. +// +// A blue zone in general is defined by a reference and an overshoot line. +// During the hinting process, all coordinate values between those two lines +// are set equal to the reference value, provided that the blue zone is not +// wider than 0.75 pixels (otherwise the blue zone gets ignored). All +// entries must have `AF_BLUE_STRING_MAX' as the final line. +// +// During the glyph analysis, edges are sorted from bottom to top, and then +// sequentially checked, edge by edge, against the blue zones in the order +// given below. +// +// +// latin auto-hinter +// ----------------- +// +// Characters in a blue string are automatically classified as having a flat +// (reference) or a round (overshoot) extremum. The blue zone is then set +// up by the mean values of all flat extrema and all round extrema, +// respectively. Only horizontal blue zones (i.e., adjusting vertical +// coordinate values) are supported. +// +// Some scripts like Khmer need character composition to get all necessary +// blue zones, since Unicode only provides an abstract data model that +// doesn't represent all possible glyph shapes. For such character +// clusters, the HarfBuzz library is used to convert them into the +// corresponding glyphs. The largest glyph element (where `largest' can be +// either `largest ascender' or `largest descender') then defines the +// corresponding flat or round extremum. +// +// For the latin auto-hinter, the overshoot should be larger than the +// reference for top zones, and vice versa for bottom zones. +// +// LATIN_TOP +// Take the maximum flat and round coordinate values of the blue string +// characters for computing the blue zone's reference and overshoot +// values. +// +// If not set, take the minimum values. +// +// Mutually exclusive with `LATIN_SUB_TOP'. +// +// LATIN_SUB_TOP +// For all glyphs of a character cluster, compute the maximum flat +// and round coordinate values of each component, then take the +// smallest of the maximum values. The idea is to get the top of +// subscript glyphs, as used in Khmer, for example. Note that +// this mechanism doesn't work for ordinary ligatures. +// +// This flags indicates a secondary blue zone: It gets removed if +// there is a non-LATIN_SUB_TOP blue zone at the same coordinate +// value (after scaling). +// +// Mutually exclusive with `LATIN_TOP'. +// +// LATIN_NEUTRAL +// Ignore round extrema and define the blue zone with flat values only. +// Both top and bottom of contours can match. This is useful for +// scripts like Devanagari where vowel signs attach to the base +// character and are implemented as components of composite glyphs. +// +// If not set, both round and flat extrema are taken into account. +// Additionally, only the top or the bottom of a contour can match, +// depending on the LATIN_TOP flag. +// +// Neutral blue zones should always follow non-neutral blue zones. +// +// LATIN_X_HEIGHT +// Scale all glyphs vertically from the corresponding script to make the +// reference line of this blue zone align on the grid. The scaling +// takes place before all other blue zones get aligned to the grid. +// Only one blue character string of a script style can have this flag. +// +// LATIN_LONG +// Apply an additional constraint for blue zone values: Don't +// necessarily use the extremum as-is but a segment of the topmost (or +// bottommost) contour that is longer than a heuristic threshold, and +// which is not too far away vertically from the real extremum. This +// ensures that small bumps in the outline are ignored (for example, the +// `vertical serifs' found in many Hebrew glyph designs). +// +// The segment must be at least EM/25 font units long, and the distance +// to the extremum must be smaller than EM/4. +// +// +// cjk auto-hinter +// --------------- +// +// Characters in a blue string are *not* automatically classified. Instead, +// first come the characters used for the overshoot value, then the +// character `|', then the characters used for the reference value +// (everything separated by space characters). The blue zone is then set up +// by the mean values of all reference values and all overshoot values, +// respectively. Both horizontal and vertical blue zones (i.e., adjusting +// vertical and horizontal coordinate values, respectively) are supported. +// +// For the cjk auto-hinter, the overshoot should be smaller than the +// reference for top zones, and vice versa for bottom zones. +// +// CJK_TOP +// Take the maximum flat and round coordinate values of the blue string +// characters. If not set, take the minimum values. +// +// CJK_RIGHT +// A synonym for CJK_TOP. If CJK_HORIZ is set, this flag indicates the +// right blue zone, taking horizontal maximum values. +// +// CJK_HORIZ +// Define a blue zone for horizontal hinting (i.e., vertical blue +// zones).

- Notes beyond the 1.93a appnote.txt: - - 1. Distance pointers never point before the beginning of the output - stream. - 2. Distance pointers can point back across blocks, up to 32k away. - 3. There is an implied maximum of 7 bits for the bit length table and - 15 bits for the actual data. - 4. If only one code exists, then it is encoded using one bit. (Zero - would be more efficient, but perhaps a little confusing.) If two - codes exist, they are coded using one bit each (0 and 1). - 5. There is no way of sending zero distance codes--a dummy must be - sent if there are none. (History: a pre 2.0 version of PKZIP would - store blocks with no distance codes, but this was discovered to be - too harsh a criterion.) Valid only for 1.93a. 2.04c does allow - zero distance codes, which is sent as one code of zero bits in - length. - 6. There are up to 286 literal/length codes. Code 256 represents the - end-of-block. Note however that the static length tree defines - 288 codes just to fill out the Huffman codes. Codes 286 and 287 - cannot be used though, since there is no length base or extra bits - defined for them. Similarily, there are up to 30 distance codes. - However, static trees define 32 codes (all 5 bits) to fill out the - Huffman codes, but the last two had better not show up in the data. - 7. Unzip can check dynamic Huffman blocks for complete code sets. - The exception is that a single code would not be complete (see #4). - 8. The five bits following the block type is really the number of - literal codes sent minus 257. - 9. Length codes 8,16,16 are interpreted as 13 length codes of 8 bits - (1+6+6). Therefore, to output three times the length, you output - three codes (1+1+1), whereas to output four times the same length, - you only need two codes (1+3). Hmm. - 10. In the tree reconstruction algorithm, Code = Code + Increment - only if BitLength(i) is not zero. (Pretty obvious.) - 11. Correction: 4 Bits: # of Bit Length codes - 4 (4 - 19) - 12.

+ * + * 1.2.beta0 24 Nov 2002 + * - First version -- complete rewrite of inflate to simplify code, avoid + * creation of window when not needed, minimize use of window when it is + * needed, make inffast.c even faster, implement gzip decoding, and to + * improve code readability and style over the previous zlib inflate code + * + * 1.2.beta1 25 Nov 2002 + * - Use pointers for available input and output checking in inffast.c + * - Remove input and output counters in inffast.c + * - Change inffast.c entry and loop from avail_in >= 7 to >= 6 + * - Remove unnecessary second byte pull from length extra in inffast.c + * - Unroll direct copy to three copies per loop in inffast.c + * + * 1.2.beta2 4 Dec 2002 + * - Change external routine names to reduce potential conflicts + * - Correct filename to inffixed.h for fixed tables in inflate.c + * - Make hbuf[] unsigned char to match parameter type in inflate.c + * - Change strm->next_out[-state->offset] to *(strm->next_out - state->offset) + * to avoid negation problem on Alphas (64 bit) in inflate.c + * + * 1.2.beta3 22 Dec 2002 + * - Add comments on state->bits assertion in inffast.c + * - Add comments on op field in inftrees.h + * - Fix bug in reuse of allocated window after inflateReset() + * - Remove bit fields--back to byte structure for speed + * - Remove distance extra == 0 check in inflate_fast()--only helps for lengths + * - Change post-increments to pre-increments in inflate_fast(), PPC biased? + * - Add compile time option, POSTINC, to use post-increments instead (Intel?) + * - Make MATCH copy in inflate() much faster for when inflate_fast() not used + * - Use local copies of stream next and avail values, as well as local bit + * buffer and bit count in inflate()--for speed when inflate_fast() not used + * + * 1.2.beta4 1 Jan 2003 + * - Split ptr - 257 statements in inflate_table() to avoid compiler warnings + * - Move a comment on output buffer sizes from inffast.c to inflate.c + * - Add comments in inffast.c to introduce the inflate_fast() routine + * - Rearrange window copies in inflate_fast() for speed and simplification + * - Unroll last copy for window match in inflate_fast() + * - Use local copies of window variables in inflate_fast() for speed + * - Pull out common wnext == 0 case for speed in inflate_fast() + * - Make op and len in inflate_fast() unsigned for consistency + * - Add FAR to lcode and dcode declarations in inflate_fast() + * - Simplified bad distance check in inflate_fast() + * - Added inflateBackInit(), inflateBack(), and inflateBackEnd() in new + * source file infback.c to provide a call-back interface to inflate for + * programs like gzip and unzip -- uses window as output buffer to avoid + * window copying + * + * 1.2.beta5 1 Jan 2003 + * - Improved inflateBack() interface to allow the caller to provide initial + * input in strm. + * - Fixed stored blocks bug in inflateBack() + * + * 1.2.beta6 4 Jan 2003 + * - Added comments in inffast.c on effectiveness of POSTINC + * - Typecasting all around to reduce compiler warnings + * - Changed loops from while (1) or do {} while (1) to for (;;), again to + * make compilers happy + * - Changed type of window in inflateBackInit() to unsigned char * + * + * 1.2.beta7 27 Jan 2003 + * - Changed many types to unsigned or unsigned short to avoid warnings + * - Added inflateCopy() function + * + * 1.2.0 9 Mar 2003 + * - Changed inflateBack() interface to provide separate opaque descriptors + * for the in() and out() functions + * - Changed inflateBack() argument and in_func typedef to swap the length + * and buffer address return values for the input function + * - Check next_in and next_out for Z_NULL on entry to inflate() + * + * The history for versions after 1.2.0 are in ChangeLog in

For example, want, need, and keep + would all have to actually be part of the saved state in case NEEDBITS() + returns: + + case STATEw: + while (want < need) { + NEEDBITS(n); + keep[want++] = BITS(n); + DROPBITS(n); + } + state = STATEx; + case STATEx: + + As shown above, if the next state is also the next case, then the break + is omitted. + + A state may also return if there is not enough output space available to + complete that state. Those states are copying stored data, writing a + literal byte, and copying a matching string. + + When returning, a "goto inf_leave" is used to update the total counters, + update the check value, and determine whether any progress has been made + during that inflate() call in order to return the proper return code. + Progress is defined as a change in either strm->avail_in or strm->avail_out. + When there is a window, goto inf_leave will update the window with the last + output written. If a goto inf_leave occurs in the middle of decompression + and there is no window currently, goto inf_leave will create one and copy + output to the window for the next call of inflate(). + + In this implementation, the flush parameter of inflate() only affects the + return code (per zlib.h). inflate() always writes as much as possible to + strm->next_out, given the space available and the provided input--the effect + documented in zlib.h of Z_SYNC_FLUSH.

There is another + * renderer called 'sdf', which generates SDF directly from outlines; + * see file `ftsdf.c` for more. + * + * * The idea of generating SDF from bitmaps is taken from two research + * papers, where one is dependent on the other: + * + * - Per-Erik Danielsson: Euclidean Distance Mapping + * http://webstaff.itn.liu.se/~stegu/JFA/Danielsson.pdf + * + * From this paper we use the eight-point sequential Euclidean + * distance mapping (8SED). This is the heart of the process used + * in this rasterizer. + * + * - Stefan Gustavson, Robin Strand: Anti-aliased Euclidean distance transform. + * http://weber.itn.liu.se/~stegu/aadist/edtaa_preprint.pdf + * + * The original 8SED algorithm discards the pixels' alpha values, + * which can contain information about the actual outline of the + * glyph. This paper takes advantage of those alpha values and + * approximates outline pretty accurately. + * + * * This rasterizer also works for monochrome bitmaps. However, the + * result is not as accurate since we don't have any way to + * approximate outlines from binary bitmaps. + * + * ======================================================================== + * + * Generating SDF from bitmap is done in several steps. + * + * (1) The only information we have is the bitmap itself. It can + * be monochrome or anti-aliased. If it is anti-aliased, pixel values + * are nothing but coverage values. These coverage values can be used + * to extract information about the outline of the image. For + * example, if the pixel's alpha value is 0.5, then we can safely + * assume that the outline passes through the center of the pixel. + * + * (2) Find edge pixels in the bitmap (see `bsdf_is_edge` for more). For + * all edge pixels we use the Anti-aliased Euclidean distance + * transform algorithm and compute approximate edge distances (see + * `compute_edge_distance` and/or the second paper for more). + * + * (3) Now that we have computed approximate distances for edge pixels we + * use the 8SED algorithm to basically sweep the entire bitmap and + * compute distances for the rest of the pixels.

For example, if the alpha value is + * 0.5f we can assume that the outline passes through the center of + * the pixel. + * + * (2) For this reason we can use that alpha value to approximate the real + * distance of the pixel to edge pretty accurately.

However, in this algorithm we use a + * different approximation which is quite accurate even for + * non-axis-aligned edges. + * + * (3) The only remaining piece of information that we cannot + * approximate directly from the alpha is the direction of the edge. + * This is where we use Sobel's operator to compute the gradient of + * the pixel. The gradient give us a pretty good approximation of + * the edge direction. We use a 3x3 kernel filter to compute the + * gradient. + * + * (4) After the above two steps we have both the direction and the + * distance to the edge which is used to generate the Signed + * Distance Field. + * + * References: + * + * - Anti-Aliased Euclidean Distance Transform: + * http://weber.itn.liu.se/~stegu/aadist/edtaa_preprint.pdf + * - Sobel Operator: + * https://en.wikipedia.org/wiki/Sobel_operator + */ + + FT_16D16_Vec g = { 0, 0 }; + FT_16D16 dist, current_alpha; + FT_16D16 a1, temp; + FT_16D16 gx, gy; + FT_16D16 alphas[9]; + + + /* Since our spread cannot be 0, this condition */ + /* can never be true. */ + if ( x <= 0 || x >= w - 1 || + y <= 0 || y >= r - 1 ) + return g; + + /* initialize the alphas */ + alphas[0] = 256 * (FT_16D16)current[-w - 1].alpha; + alphas[1] = 256 * (FT_16D16)current[-w ].alpha; + alphas[2] = 256 * (FT_16D16)current[-w + 1].alpha; + alphas[3] = 256 * (FT_16D16)current[ -1].alpha; + alphas[4] = 256 * (FT_16D16)current[ 0].alpha; + alphas[5] = 256 * (FT_16D16)current[ 1].alpha; + alphas[6] = 256 * (FT_16D16)current[ w - 1].alpha; + alphas[7] = 256 * (FT_16D16)current[ w ].alpha; + alphas[8] = 256 * (FT_16D16)current[ w + 1].alpha; + + current_alpha = alphas[4]; + + /* Compute the gradient using the Sobel operator. */ + /* In this case we use the following 3x3 filters: */ + /* */ + /* For x: | -1 0 -1 | */ + /* | -root(2) 0 root(2) | */ + /* | -1 0 1 | */ + /* */ + /* For y: | -1 -root(2) -1 | */ + /* | 0 0 0 | */ + /* | 1 root(2) 1 | */ + /* */ + /* [Note]: 92681 is root(2) in 16.16 format. */ + g.x = -alphas[0] - + FT_MulFix( alphas[3], 92681 ) - + alphas[6] + + alphas[2] + + FT_MulFix( alphas[5], 92681 ) + + alphas[8]; + + g.y = -alphas[0] - + FT_MulFix( alphas[1], 92681 ) - + alphas[2] + + alphas[6] + + FT_MulFix( alphas[7], 92681 ) + + alphas[8]; + + FT_Vector_NormLen( &g ); + + /* The gradient gives us the direction of the */ + /* edge for the current pixel.

There is + * another renderer called 'bsdf', which converts bitmaps to SDF; see + * file `ftbsdf.c` for more. + * + * * The basic idea of generating the SDF is taken from Viktor Chlumsky's + * research paper. The paper explains both single and multi-channel + * SDF, however, this implementation only generates single-channel SDF. + * + * Chlumsky, Viktor: Shape Decomposition for Multi-channel Distance + * Fields. Master's thesis. Czech Technical University in Prague, + * Faculty of InformationTechnology, 2015. + * + * For more information: https://github.com/Chlumsky/msdfgen + * + * ======================================================================== + * + * Generating SDF from outlines is pretty straightforward. + * + * (1) We have a set of contours that make the outline of a shape/glyph. + * Each contour comprises of several edges, with three types of edges. + * + * * line segments + * * conic Bezier curves + * * cubic Bezier curves + * + * (2) Apart from the outlines we also have a two-dimensional grid, namely + * the bitmap that is used to represent the final SDF data. + * + * (3) In order to generate SDF, our task is to find shortest signed + * distance from each grid point to the outline. The 'signed + * distance' means that if the grid point is filled by any contour + * then its sign is positive, otherwise it is negative. The pseudo + * code is as follows. + * + * ``` + * foreach grid_point (x, y): + * { + * int min_dist = INT_MAX; + * + * foreach contour in outline: + * { + * foreach edge in contour: + * { + * // get shortest distance from point (x, y) to the edge + * d = get_min_dist(x, y, edge); + * + * if (d < min_dist) + * min_dist = d; + * } + * + * bitmap[x, y] = min_dist; + * } + * } + * ``` + * + * (4) After running this algorithm the bitmap contains information about + * the shortest distance from each point to the outline of the shape. + * Of course, while this is the most straightforward way of generating + * SDF, we use various optimizations in our implementation. See the + * `sdf_generate_*' functions in this file for all details. + * + * The optimization currently used by default is subdivision; see + * function `sdf_generate_subdivision` for more. + * + * Also, to see how we compute the shortest distance from a point to + * each type of edge, check out the `get_min_distance_*' functions. + * + */ + + + /************************************************************************** + * + * The macro FT_COMPONENT is used in trace mode.

This is achieved through several hacks + * in the base (v35) interpreter, as detailed below. + * + * ClearType is an umbrella term for several rendering techniques + * employed by Microsoft's various GUI and rendering toolkit + * implementations, most importantly: subpixel rendering for using the + * RGB subpixels of LCDs to approximately triple the perceived + * resolution on the x-axis and subpixel hinting for positioning stems + * on subpixel borders. TrueType programming is explicit, i.e., fonts + * must be programmed to take advantage of ClearType's possibilities. + * + * When ClearType was introduced, it seemed unlikely that all fonts + * would be reprogrammed, so Microsoft decided to implement a backward + * compatibility mode. It employs several simple to complicated + * assumptions and tricks, many of them font-dependent, that modify the + * interpretation of the bytecode contained in these fonts to retrofit + * them into a ClearType-y look. The quality of the results varies. + * Most (web)fonts that were released since then have come to rely on + * these hacks to render correctly, even some of Microsoft's flagship + * fonts (e.g., Calibri, Cambria, Segoe UI). + * + * FreeType's minimal subpixel hinting code (interpreter version 40) + * employs a small list of font-agnostic hacks loosely based on the + * public information available on Microsoft's compatibility mode[2]. + * The focus is on modern (web)fonts rather than legacy fonts that were + * made for monochrome rendering. It will not match ClearType rendering + * exactly. Unlike the `Infinality' code (interpreter version 38) that + * came before, it will not try to toggle hacks for specific fonts for + * performance and complexity reasons. It will fall back to version 35 + * behavior for tricky fonts[1] or when monochrome rendering is + * requested. + * + * 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 backward 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].
