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_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_NO_RECURSE :: - * Indicate 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 - * 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 :: - * 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. - * - * 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 ) - - /* */ - - /* 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.

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_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_NO_RECURSE :: + * Indicate 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 + * 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 :: + * 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. + * + * FT_LOAD_COMPUTE_METRICS :: + * This flag sets computing glyph metrics without the use of bundled + * metrics tables (for example, the `hdmx' table in TrueType fonts). + * Well-behaving fonts have optimized bundled metrics and these should + * be used. 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_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.

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.

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. + * + * @order: + * hinting-engine + * no-stem-darkening + * darkening-parameters + * + */ + + + /************************************************************************** + * + * @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.

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

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. - * - * @order: - * hinting-engine - * no-stem-darkening - * darkening-parameters - * - */ - - - /************************************************************************** - * - * @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.
