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 :: * [Since 2.5] 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 :: * [Since 2.6.1] 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 :: * [Since 2.7.1] Request loading of the metrics and bitmap image * information of a (possibly embedded) bitmap glyph without * allocating or copying the bitmap image data itself. No effect if * the target glyph is not a bitmap image. * * This flag unsets @FT_LOAD_RENDER. * * FT_LOAD_CROP_BITMAP :: * Ignored. Deprecated. * * FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH :: * Ignored. Deprecated. * * @note: * By default, hinting is enabled and the font's native hinter (see * @FT_FACE_FLAG_HINTER) is preferred over the auto-hinter. You can * disable hinting by setting @FT_LOAD_NO_HINTING or change the * precedence by setting @FT_LOAD_FORCE_AUTOHINT. You can also set * @FT_LOAD_NO_AUTOHINT in case you don't want the auto-hinter to be * used at all. * * See the description of @FT_FACE_FLAG_TRICKY for a special exception * (affecting only a handful of Asian fonts). * * Besides deciding which hinter to use, you can also decide which * hinting algorithm to use. See @FT_LOAD_TARGET_XXX for details. * * Note that the auto-hinter needs a valid Unicode cmap (either a native * one or synthesized by FreeType) for producing correct results. If a * font provides an incorrect mapping (for example, assigning the * character code U+005A, LATIN CAPITAL LETTER Z, to a glyph depicting a * mathematical integral sign), the auto-hinter might produce useless * results. * */ #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 ) #define FT_LOAD_COMPUTE_METRICS ( 1L << 21 ) #define FT_LOAD_BITMAP_METRICS_ONLY ( 1L << 22 ) /* */ /* 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 to select a specific hinting algorithm for the * hinter.

For monochrome output, use @FT_LOAD_TARGET_MONO * instead. * * FT_LOAD_TARGET_LIGHT :: * A lighter hinting algorithm for gray-level modes. Many generated * glyphs are fuzzier but better resemble their original shape. This * is achieved by snapping glyphs to the pixel grid only vertically * (Y-axis), as is done by FreeType's new CFF engine or Microsoft's * ClearType font renderer. This preserves inter-glyph spacing in * horizontal text. The snapping is done either by the native font * driver, if the driver itself and the font support it, or by the * auto-hinter. * * Advance widths are rounded to integer values; however, using the * `lsb_delta' and `rsb_delta' fields of @FT_GlyphSlotRec, it is * possible to get fractional advance widths for subpixel positioning * (which is recommended to use). * * If configuration option AF_CONFIG_OPTION_TT_SIZE_METRICS is active, * TrueType-like metrics are used to make this mode behave similarly * as in unpatched FreeType versions between 2.4.6 and 2.7.1 * (inclusive). * * FT_LOAD_TARGET_MONO :: * Strong hinting algorithm that should only be used for monochrome * output.

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.

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.

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

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.

The default FreeType LCD * rendering uses different technology, and API described below, * although available, does nothing. * * 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. 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. * * 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. When used with subpixel rendering, this * results in sometimes severe color fringes. * * FT_LCD_FILTER_DEFAULT :: * The default filter reduces color fringes considerably, at the cost * of a slight blurriness in the output. * * It is a beveled, normalized, and color-balanced five-tap filter * that is more forgiving to screens with non-ideal gamma curves and * viewing angles. Note that while color-fringing is reduced, it can * only be minimized by using linear alpha blending and gamma * correction to render glyphs onto surfaces.
