See also the `num_fixed_sizes` - * and `available_sizes` fields of @FT_FaceRec. - * - * FT_FACE_FLAG_FIXED_WIDTH :: - * The face contains fixed-width characters (like Courier, Lucida, - * MonoType, etc.). - * - * FT_FACE_FLAG_SFNT :: - * The face uses the SFNT storage scheme. For now, this means TrueType - * and OpenType. - * - * FT_FACE_FLAG_HORIZONTAL :: - * The face contains horizontal glyph metrics. This should be set for - * all common formats. - * - * FT_FACE_FLAG_VERTICAL :: - * The face contains vertical glyph metrics. This is only available in - * some formats, not all of them. - * - * FT_FACE_FLAG_KERNING :: - * The face contains kerning information. If set, the kerning distance - * can be retrieved using the function @FT_Get_Kerning. Otherwise the - * function always return the vector (0,0). Note that FreeType doesn't - * handle kerning data from the SFNT 'GPOS' table (as present in many - * OpenType fonts). - * - * FT_FACE_FLAG_FAST_GLYPHS :: - * THIS FLAG IS DEPRECATED. DO NOT USE OR TEST IT. - * - * FT_FACE_FLAG_MULTIPLE_MASTERS :: - * The face contains multiple masters and is capable of interpolating - * between them. Supported formats are Adobe MM, TrueType GX, and - * OpenType variation fonts. - * - * See section @multiple_masters for API details. - * - * FT_FACE_FLAG_GLYPH_NAMES :: - * The face contains glyph names, which can be retrieved using - * @FT_Get_Glyph_Name. Note that some TrueType fonts contain broken - * glyph name tables. Use the function @FT_Has_PS_Glyph_Names when - * needed. - * - * FT_FACE_FLAG_EXTERNAL_STREAM :: - * Used internally by FreeType to indicate that a face's stream was - * provided by the client application and should not be destroyed when - * @FT_Done_Face is called. Don't read or test this flag. - * - * FT_FACE_FLAG_HINTER :: - * The font driver has a hinting machine of its own. For example, with - * TrueType fonts, it makes sense to use data from the SFNT 'gasp' - * table only if the native TrueType hinting engine (with the bytecode - * interpreter) is available and active. - * - * FT_FACE_FLAG_CID_KEYED :: - * The face is CID-keyed. In that case, the face is not accessed by - * glyph indices but by CID values. For subsetted CID-keyed fonts this - * has the consequence that not all index values are a valid argument - * to @FT_Load_Glyph. Only the CID values for which corresponding - * glyphs in the subsetted font exist make `FT_Load_Glyph` return - * successfully; in all other cases you get an - * `FT_Err_Invalid_Argument` error. - * - * Note that CID-keyed fonts that are in an SFNT wrapper (this is, all - * OpenType/CFF fonts) don't have this flag set since the glyphs are - * accessed in the normal way (using contiguous indices); the - * 'CID-ness' isn't visible to the application. - * - * FT_FACE_FLAG_TRICKY :: - * The face is 'tricky', this is, it always needs the font format's - * native hinting engine to get a reasonable result. A typical example - * is the old Chinese font `mingli.ttf` (but not `mingliu.ttc`) that - * uses TrueType bytecode instructions to move and scale all of its - * subglyphs. - * - * It is not possible to auto-hint such fonts using - * @FT_LOAD_FORCE_AUTOHINT; it will also ignore @FT_LOAD_NO_HINTING. - * You have to set both @FT_LOAD_NO_HINTING and @FT_LOAD_NO_AUTOHINT to - * really disable hinting; however, you probably never want this except - * for demonstration purposes. - * - * Currently, there are about a dozen TrueType fonts in the list of - * tricky fonts; they are hard-coded in file `ttobjs.c`. - * - * FT_FACE_FLAG_COLOR :: - * [Since 2.5.1] The face has color glyph tables. See @FT_LOAD_COLOR - * for more information. - * - * FT_FACE_FLAG_VARIATION :: - * [Since 2.9] Set if the current face (or named instance) has been - * altered with @FT_Set_MM_Design_Coordinates, - * @FT_Set_Var_Design_Coordinates, or @FT_Set_Var_Blend_Coordinates. - * This flag is unset by a call to @FT_Set_Named_Instance. - * - * FT_FACE_FLAG_SVG :: - * [Since 2.12] The face has an 'SVG~' OpenType table. - * - * FT_FACE_FLAG_SBIX :: - * [Since 2.12] The face has an 'sbix' OpenType table *and* outlines. - * For such fonts, @FT_FACE_FLAG_SCALABLE is not set by default to - * retain backward compatibility. - * - * FT_FACE_FLAG_SBIX_OVERLAY :: - * [Since 2.12] The face has an 'sbix' OpenType table where outlines - * should be drawn on top of bitmap strikes. - * - */ -#define FT_FACE_FLAG_SCALABLE ( 1L << 0 ) -#define FT_FACE_FLAG_FIXED_SIZES ( 1L << 1 ) -#define FT_FACE_FLAG_FIXED_WIDTH ( 1L << 2 ) -#define FT_FACE_FLAG_SFNT ( 1L << 3 ) -#define FT_FACE_FLAG_HORIZONTAL ( 1L << 4 ) -#define FT_FACE_FLAG_VERTICAL ( 1L << 5 ) -#define FT_FACE_FLAG_KERNING ( 1L << 6 ) -#define FT_FACE_FLAG_FAST_GLYPHS ( 1L << 7 ) -#define FT_FACE_FLAG_MULTIPLE_MASTERS ( 1L << 8 ) -#define FT_FACE_FLAG_GLYPH_NAMES ( 1L << 9 ) -#define FT_FACE_FLAG_EXTERNAL_STREAM ( 1L << 10 ) -#define FT_FACE_FLAG_HINTER ( 1L << 11 ) -#define FT_FACE_FLAG_CID_KEYED ( 1L << 12 ) -#define FT_FACE_FLAG_TRICKY ( 1L << 13 ) -#define FT_FACE_FLAG_COLOR ( 1L << 14 ) -#define FT_FACE_FLAG_VARIATION ( 1L << 15 ) -#define FT_FACE_FLAG_SVG ( 1L << 16 ) -#define FT_FACE_FLAG_SBIX ( 1L << 17 ) -#define FT_FACE_FLAG_SBIX_OVERLAY ( 1L << 18 ) - - - /************************************************************************** - * - * @macro: - * FT_HAS_HORIZONTAL - * - * @description: - * A macro that returns true whenever a face object contains horizontal - * metrics (this is true for all font formats though). - * - * @also: - * @FT_HAS_VERTICAL can be used to check for vertical metrics. - * - */ -#define FT_HAS_HORIZONTAL( face ) \ - ( !!( (face)->face_flags & FT_FACE_FLAG_HORIZONTAL ) ) - - - /************************************************************************** - * - * @macro: - * FT_HAS_VERTICAL - * - * @description: - * A macro that returns true whenever a face object contains real - * vertical metrics (and not only synthesized ones). - * - */ -#define FT_HAS_VERTICAL( face ) \ - ( !!( (face)->face_flags & FT_FACE_FLAG_VERTICAL ) ) - - - /************************************************************************** - * - * @macro: - * FT_HAS_KERNING - * - * @description: - * A macro that returns true whenever a face object contains kerning data - * that can be accessed with @FT_Get_Kerning. - * - */ -#define FT_HAS_KERNING( face ) \ - ( !!( (face)->face_flags & FT_FACE_FLAG_KERNING ) ) - - - /************************************************************************** - * - * @macro: - * FT_IS_SCALABLE - * - * @description: - * A macro that returns true whenever a face object contains a scalable - * font face (true for TrueType, Type~1, Type~42, CID, OpenType/CFF, and - * PFR font formats). - * - */ -#define FT_IS_SCALABLE( face ) \ - ( !!( (face)->face_flags & FT_FACE_FLAG_SCALABLE ) ) - - - /************************************************************************** - * - * @macro: - * FT_IS_SFNT - * - * @description: - * A macro that returns true whenever a face object contains a font whose - * format is based on the SFNT storage scheme.

This field is only - * valid for the composite glyph format that should normally only be - * loaded with the @FT_LOAD_NO_RECURSE flag. - * - * subglyphs :: - * An array of subglyph descriptors for composite glyphs.

Currently internal to FreeType. - * - * control_data :: - * Certain font drivers can also return the control data for a given - * glyph image (e.g. TrueType bytecode, Type~1 charstrings, etc.). - * This field is a pointer to such data; it is currently internal to - * FreeType. - * - * control_len :: - * This is the length in bytes of the control data. Currently internal - * to FreeType. - * - * other :: - * Reserved. - * - * lsb_delta :: - * The difference between hinted and unhinted left side bearing while - * auto-hinting is active. Zero otherwise. - * - * rsb_delta :: - * The difference between hinted and unhinted right side bearing while - * auto-hinting is active. Zero otherwise. - * - * @note: - * If @FT_Load_Glyph is called with default flags (see @FT_LOAD_DEFAULT) - * the glyph image is loaded in the glyph slot in its native format - * (e.g., an outline glyph for TrueType and Type~1 formats). [Since 2.9] - * The prospective bitmap metrics are calculated according to - * @FT_LOAD_TARGET_XXX and other flags even for the outline glyph, even - * if @FT_LOAD_RENDER is not set. - * - * This image can later be converted into a bitmap by calling - * @FT_Render_Glyph. This function searches the current renderer for the - * native image's format, then invokes it. - * - * The renderer is in charge of transforming the native image through the - * slot's face transformation fields, then converting it into a bitmap - * that is returned in `slot->bitmap`. - * - * Note that `slot->bitmap_left` and `slot->bitmap_top` are also used to - * specify the position of the bitmap relative to the current pen - * position (e.g., coordinates (0,0) on the baseline). Of course, - * `slot->format` is also changed to @FT_GLYPH_FORMAT_BITMAP. - * - * Here is a small pseudo code fragment that shows how to use `lsb_delta` - * and `rsb_delta` to do fractional positioning of glyphs: - * - * ``` - * FT_GlyphSlot slot = face->glyph; - * FT_Pos origin_x = 0; - * - * - * for all glyphs do - * - * - * FT_Outline_Translate( slot->outline, origin_x & 63, 0 ); - * - * - * - * - * - * origin_x += slot->advance.x; - * origin_x += slot->lsb_delta - slot->rsb_delta; - * endfor - * ``` - * - * Here is another small pseudo code fragment that shows how to use - * `lsb_delta` and `rsb_delta` to improve integer positioning of glyphs: - * - * ``` - * FT_GlyphSlot slot = face->glyph; - * FT_Pos origin_x = 0; - * FT_Pos prev_rsb_delta = 0; - * - * - * for all glyphs do - * - * - * - * - * if ( prev_rsb_delta - slot->lsb_delta > 32 ) - * origin_x -= 64; - * else if ( prev_rsb_delta - slot->lsb_delta < -31 ) - * origin_x += 64; - * - * prev_rsb_delta = slot->rsb_delta; - * - * - * - * origin_x += slot->advance.x; - * endfor - * ``` - * - * If you use strong auto-hinting, you **must** apply these delta values! - * Otherwise you will experience far too large inter-glyph spacing at - * small rendering sizes in most cases. Note that it doesn't harm to use - * the above code for other hinting modes also, since the delta values - * are zero then. - */ - typedef struct FT_GlyphSlotRec_ - { - FT_Library library; - FT_Face face; - FT_GlyphSlot next; - FT_UInt glyph_index; /* new in 2.10; was reserved previously */ - FT_Generic generic; - - FT_Glyph_Metrics metrics; - FT_Fixed linearHoriAdvance; - FT_Fixed linearVertAdvance; - FT_Vector advance; - - FT_Glyph_Format format; - - FT_Bitmap bitmap; - FT_Int bitmap_left; - FT_Int bitmap_top; - - FT_Outline outline; - - FT_UInt num_subglyphs; - FT_SubGlyph subglyphs; - - void* control_data; - long control_len; - - FT_Pos lsb_delta; - FT_Pos rsb_delta; - - void* other; - - FT_Slot_Internal internal; - - } FT_GlyphSlotRec; - - - /*************************************************************************/ - /*************************************************************************/ - /* */ - /* F U N C T I O N S */ - /* */ - /*************************************************************************/ - /*************************************************************************/ - - - /************************************************************************** - * - * @function: - * FT_Init_FreeType - * - * @description: - * Initialize a new FreeType library object.

See also the - * note below. - * - * FT_LOAD_PEDANTIC :: - * Make the font driver perform pedantic verifications during glyph - * loading and hinting. This is mostly used to detect broken glyphs in - * fonts.

The - * description of subglyphs can then be accessed with - * @FT_Get_SubGlyph_Info. - * - * Don't use this flag for retrieving metrics information since some - * font drivers only return rudimentary data. - * - * 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.

FreeType searches in the following order; - * there are slight differences depending on the font format. - * - * [Since 2.5] Load embedded color bitmap images (provided - * @FT_LOAD_NO_BITMAP is not set). The resulting color bitmaps, if - * available, have the @FT_PIXEL_MODE_BGRA format, with pre-multiplied - * color channels. If the flag is not set and color bitmaps are found, - * they are converted to 256-level gray bitmaps, using the - * @FT_PIXEL_MODE_GRAY format. - * - * [Since 2.12] If the glyph index maps to an entry in the face's - * 'SVG~' table, load the associated SVG document from this table and - * set the `format` field of @FT_GlyphSlotRec to @FT_GLYPH_FORMAT_SVG. - * Note that FreeType itself can't render SVG documents; however, the - * library provides hooks to seamlessly integrate an external renderer. - * See sections @ot_svg_driver and @svg_fonts for more. - * - * [Since 2.10, experimental] If the glyph index maps to an entry in - * the face's 'COLR' table with a 'CPAL' palette table (as defined in - * the OpenType specification), make @FT_Render_Glyph provide a default - * blending of the color glyph layers associated with the glyph index, - * using the same bitmap format as embedded color bitmap images. This - * is mainly for convenience and works only for glyphs in 'COLR' v0 - * tables (or glyphs in 'COLR' v1 tables that exclusively use v0 - * features). For full control of color layers use - * @FT_Get_Color_Glyph_Layer and FreeType's color functions like - * @FT_Palette_Select instead of setting @FT_LOAD_COLOR for rendering - * so that the client application can handle blending by itself. - * - * 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.

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 anti-aliased 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.

Sometimes the - * vertical stems may be only partially black. In this context, - * 'anti-aliasing' means that stems are not positioned exactly on pixel - * borders, causing a fuzzy appearance. - * - * There are two principles behind this approach. - * - * 1) No hinting in the horizontal direction: Unlike 'superhinted' - * TrueType, which changes glyph widths to accommodate regular - * inter-glyph spacing, Adobe's approach is 'faithful to the design' in - * representing both the glyph width and the inter-glyph spacing designed - * for the font. This makes the screen display as close as it can be to - * the result one would get with infinite resolution, while preserving - * what is considered the key characteristics of each glyph. Note that - * the distances between unhinted and grid-fitted positions at small - * sizes are comparable to kerning values and thus would be noticeable - * (and distracting) while reading if hinting were applied. - * - * One of the reasons to not hint horizontally is anti-aliasing for LCD - * screens: The pixel geometry of modern displays supplies three vertical - * subpixels as the eye moves horizontally across each visible pixel. On - * devices where we can be certain this characteristic is present a - * rasterizer can take advantage of the subpixels to add increments of - * weight. In Western writing systems this turns out to be the more - * critical direction anyway; the weights and spacing of vertical stems - * (see above) are central to Armenian, Cyrillic, Greek, and Latin type - * designs. Even when the rasterizer uses greyscale anti-aliasing instead - * of color (a necessary compromise when one doesn't know the screen - * characteristics), the unhinted vertical features preserve the design's - * weight and spacing much better than aliased type would. - * - * 2) Alignment in the vertical direction: Weights and spacing along the - * y~axis are less critical; what is much more important is the visual - * alignment of related features (like cap-height and x-height). The - * sense of alignment for these is enhanced by the sharpness of grid-fit - * edges, while the cruder vertical resolution (full pixels instead of - * 1/3 pixels) is less of a problem. - * - * On the technical side, horizontal alignment zones for ascender, - * x-height, and other important height values (traditionally called - * 'blue zones') as defined in the font are positioned independently, - * each being rounded to the nearest pixel edge, taking care of overshoot - * suppression at small sizes, stem darkening, and scaling. - * - * Hstems (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: - * ot_svg_driver - * - * @title: - * The SVG driver - * - * @abstract: - * Controlling the external rendering of OT-SVG glyphs. - * - * @description: - * By default, FreeType can only load the 'SVG~' table of OpenType fonts - * if configuration macro `FT_CONFIG_OPTION_SVG` is defined.

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