In this + * case, the following will happen: + * + * 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 vector outline being loaded to 26.6 fractional + * pixels, but kept in font units. Note that this also disables + * hinting and the loading of embedded bitmaps. You should only use it + * when you want to retrieve the original glyph outlines in font units. + * + * FT_LOAD_NO_HINTING :: + * Don't hint glyph outlines after their scaling to device pixels. + * This generally generates "blurrier" glyphs in anti-aliased modes. + * + * This flag is ignored if @FT_LOAD_NO_SCALE is set. + * + * FT_LOAD_RENDER :: + * Render the glyph outline immediately into a bitmap before the glyph + * loader returns. By default, the glyph is rendered for the + * @FT_RENDER_MODE_NORMAL mode, which corresponds to 8-bit anti-aliased + * bitmaps using 256 opacity levels. You can use either + * @FT_LOAD_TARGET_MONO or @FT_LOAD_MONOCHROME to render 1-bit + * monochrome bitmaps. + * + * This flag is ignored if @FT_LOAD_NO_SCALE is set. + * + * FT_LOAD_NO_BITMAP :: + * Don't look for bitmaps when loading the glyph. Only scalable + * outlines will be loaded when available, and scaled, hinted, or + * rendered depending on other bit flags. + * + * This does not prevent you from rendering outlines to bitmaps + * with @FT_LOAD_RENDER, however. + * + * FT_LOAD_VERTICAL_LAYOUT :: + * Prepare the glyph image for vertical text layout. This basically + * means that `face.glyph.advance' will correspond to the vertical + * advance height (instead of the default horizontal advance width), + * and that the glyph image will be translated to match the vertical + * bearings positions. + * + * FT_LOAD_FORCE_AUTOHINT :: + * Force the use of the FreeType auto-hinter when a glyph outline is + * loaded. You shouldn't need this in a typical application, since it + * is mostly used to experiment with its algorithm. + * + * FT_LOAD_CROP_BITMAP :: + * Indicates that the glyph loader should try to crop the bitmap (i.e., + * remove all space around its black bits) when loading it. This is + * only useful when loading embedded bitmaps in certain fonts, since + * bitmaps rendered with @FT_LOAD_RENDER are always cropped by default. + * + * FT_LOAD_PEDANTIC :: + * Indicates that the glyph loader should perform pedantic + * verifications during glyph loading, rejecting invalid fonts. This + * is mostly used to detect broken glyphs in fonts. By default, + * FreeType tries to handle broken fonts also. + * + * FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH :: + * Indicates that the glyph loader should ignore the global advance + * width defined in the font. As far as we know, this is only used by + * the X-TrueType font server, in order to deal correctly with the + * incorrect metrics contained in DynaLab's TrueType CJK fonts. + * + * FT_LOAD_NO_RECURSE :: + * This flag is only used internally. It merely indicates that the + * glyph loader 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. + * + * FT_LOAD_IGNORE_TRANSFORM :: + * Indicates that the glyph loader should not try to transform the + * loaded glyph image. This doesn't prevent scaling, hinting, or + * rendering. + * + * FT_LOAD_MONOCHROME :: + * This flag is used with @FT_LOAD_RENDER to indicate that you want + * to render a 1-bit monochrome glyph bitmap from a vectorial outline. + * + * Note that this has no effect on the hinting algorithm used by the + * glyph loader. You should better use @FT_LOAD_TARGET_MONO if you + * want to render monochrome-optimized glyph images instead. + * + * FT_LOAD_LINEAR_DESIGN :: + * Return the linearly scaled metrics expressed in original font units + * instead of the default 16.16 pixel values. + * + * FT_LOAD_NO_AUTOHINT :: + * Indicates that the auto-hinter should never be used to hint glyph + * outlines. This doesn't prevent native format-specific hinters from + * being used. This can be important for certain fonts where unhinted + * output is better than auto-hinted one. + */ +#define FT_LOAD_NO_SCALE 0x1 +#define FT_LOAD_NO_HINTING 0x2 +#define FT_LOAD_RENDER 0x4 +#define FT_LOAD_NO_BITMAP 0x8 +#define FT_LOAD_VERTICAL_LAYOUT 0x10 +#define FT_LOAD_FORCE_AUTOHINT 0x20 +#define FT_LOAD_CROP_BITMAP 0x40 +#define FT_LOAD_PEDANTIC 0x80 +#define FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH 0x200 +#define FT_LOAD_NO_RECURSE 0x400 +#define FT_LOAD_IGNORE_TRANSFORM 0x800 +#define FT_LOAD_MONOCHROME 0x1000 +#define FT_LOAD_LINEAR_DESIGN 0x2000 + + /* temporary hack! */ +#define FT_LOAD_SBITS_ONLY 0x4000 +#define FT_LOAD_NO_AUTOHINT 0x8000U + + /* */ + +#define FT_LOAD_TARGET_( x ) ( (FT_Int32)( (x) & 15 ) << 16 ) +#define FT_LOAD_TARGET_MODE( x ) ( (FT_Render_Mode)( ( (x) >> 16 ) & 15 ) ) + +#define FT_LOAD_TARGET_NORMAL FT_LOAD_TARGET_( FT_RENDER_MODE_NORMAL ) +#define FT_LOAD_TARGET_LIGHT FT_LOAD_TARGET_( FT_RENDER_MODE_LIGHT ) +#define FT_LOAD_TARGET_MONO FT_LOAD_TARGET_( FT_RENDER_MODE_MONO ) +#define FT_LOAD_TARGET_LCD FT_LOAD_TARGET_( FT_RENDER_MODE_LCD ) +#define FT_LOAD_TARGET_LCD_V FT_LOAD_TARGET_( FT_RENDER_MODE_LCD_V ) + +#define FT_LOAD_DEFAULT 0x0 + + + /*************************************************************************/ + /* */ + /* <Function> */ + /* FT_Set_Transform */ + /* */ + /* <Description> */ + /* A function used to set the transformation that is applied to glyph */ + /* images just before they are converted to bitmaps in a glyph slot */ + /* when @FT_Render_Glyph is called. */ + /* */ + /* <InOut> */ + /* face :: A handle to the source face object. */ + /* */ + /* <Input> */ + /* matrix :: A pointer to the transformation's 2x2 matrix.
