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.

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: - * hinting-engine[cff] - * - * @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.

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: - * FT_LcdFilter - * - * @description: - * A list of values to identify various types of LCD filters. - * - * @values: - * FT_LCD_FILTER_NONE :: - * Do not perform filtering.

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.

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. - * - */ -#define TT_INTERPRETER_VERSION_35 35 -#define TT_INTERPRETER_VERSION_38 38 -#define TT_INTERPRETER_VERSION_40 40 - - /* */ - - -FT_END_HEADER - - -#endif /* FTTTDRV_H_ */ - - -/* END */ diff --git a/third_party/freetype/include/freetype/fttypes.h b/third_party/freetype/include/freetype/fttypes.h deleted file mode 100644 index eab8adaad4..0000000000 --- a/third_party/freetype/include/freetype/fttypes.h +++ /dev/null @@ -1,602 +0,0 @@ -/***************************************************************************/ -/* */ -/* fttypes.h */ -/* */ -/* FreeType simple types definitions (specification only). */ -/* */ -/* Copyright 1996-2017 by */ -/* David Turner, Robert Wilhelm, and Werner Lemberg. */ -/* */ -/* This file is part of the FreeType project, and may only be used, */ -/* modified, and distributed under the terms of the FreeType project */ -/* license, LICENSE.TXT.

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. - * - */ - - /* Using v40 implies subpixel hinting.
