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_CROP_BITMAP :: - * Indicates that the font driver should crop the loaded bitmap glyph - * (i.e., remove all space around its black bits). Not all drivers - * implement this. - * - * 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_IGNORE_GLOBAL_ADVANCE_WIDTH :: - * Ignored. Deprecated. - * - * FT_LOAD_NO_RECURSE :: - * This flag is only used internally. It merely indicates 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 sub-glyphs is not available to client - * applications for now. - * - * 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. - * - * @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.

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.
