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

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'.

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.

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.

However, this does not translate + * to 50% brightness for that pixel on our sRGB and gamma~2.2 screens. + * Due to their non-linearity, they dwell longer in the darks and only a + * pixel value of about 186 results in 50% brightness -- 128 ends up too + * dark on both bright and dark backgrounds. The net result is that dark + * text looks burnt-out, pixely and blotchy on bright background, bright + * text too frail on dark backgrounds, and colored text on colored + * background (for example, red on green) seems to have dark halos or + * 'dirt' around it. The situation is especially ugly for diagonal stems + * like in 'w' glyph shapes where the quality of FreeType's anti-aliasing + * depends on the correct display of grays. On high-DPI screens where + * smaller, fully black pixels reign supreme, this doesn't matter, but on + * our low-DPI screens with all the gray shades, it does. 0% and 100% + * brightness are the same things in linear and non-linear space, just + * all the shades in-between aren't. + * + * The blending function for placing text over a background is + * + * ``` + * dst = alpha * src + (1 - alpha) * dst , + * ``` + * + * which is known as the OVER operator. + * + * To correctly composite an antialiased pixel of a glyph onto a surface, + * + * 1. take the foreground and background colors (e.g., in sRGB space) + * and apply gamma to get them in a linear space, + * + * 2. use OVER to blend the two linear colors using the glyph pixel + * as the alpha value (remember, the glyph bitmap is an alpha coverage + * bitmap), and + * + * 3. apply inverse gamma to the blended pixel and write it back to + * the image. + * + * Internal testing at Adobe found that a target inverse gamma of~1.8 for + * step~3 gives good results across a wide range of displays with an sRGB + * gamma curve or a similar one. + * + * This process can cost performance.

A + * subpixel-rendered glyph must first be filtered with a filter that + * gives equal weight to the three color primaries and does not exceed a + * sum of 0x100, see section @lcd_rendering.

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.

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 + * 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 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. + * + */ + + + /************************************************************************** + * + * @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: + * properties + * + * @title: + * Driver properties + * + * @abstract: + * Controlling driver modules. + * + * @description: + * Driver modules can be controlled by setting and unsetting properties, + * using the functions @FT_Property_Set and @FT_Property_Get.

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.
