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. + * + * @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.
