This is useful to reduce color fringes - * that would occur with unfiltered rendering. + * Subpixel 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. Since these + * subpixels are color pixels, using them unfiltered creates severe + * color fringes. Use the @FT_Library_SetLcdFilter API to specify a + * low-pass filter, which is then applied to subpixel-rendered bitmaps + * generated through @FT_Render_Glyph. The filter sacrifices some of + * the higher resolution to reduce color fringes, making the glyph image + * slightly blurrier. Positional improvements will remain. * * Note that no filter is active by default, and that this function is * *not* implemented in default builds of the library. You need to * #define FT_CONFIG_OPTION_SUBPIXEL_RENDERING in your `ftoption.h' file - * in order to activate it. - * - * FreeType generates alpha coverage maps, which are linear by nature. - * For instance, the value 0x80 in bitmap representation means that - * (within numerical precision) 0x80/0xFF fraction of that pixel is - * covered by the glyph's outline. The blending function for placing - * text over a background is - * - * { - * dst = alpha * src + (1 - alpha) * dst , - * } - * - * which is known as OVER. However, when calculating the output of the - * OVER operator, the source colors should first be transformed to a - * linear color space, then alpha blended in that space, and transformed - * back to the output color space. - * - * When linear light blending is used, the default FIR5 filtering - * weights (as given by FT_LCD_FILTER_DEFAULT) are no longer optimal, as - * they have been designed for black on white rendering while lacking - * gamma correction. To preserve color neutrality, weights for a FIR5 - * filter should be chosen according to two free parameters `a' and `c', - * and the FIR weights should be - * - * { - * [a - c, a + c, 2 * a, a + c, a - c] . - * } - * - * This formula generates equal weights for all the color primaries - * across the filter kernel, which makes it colorless. One suggested - * set of weights is - * - * { - * [0x10, 0x50, 0x60, 0x50, 0x10] , - * } - * - * where `a' has value 0x30 and `b' value 0x20. The weights in filter - * may have a sum larger than 0x100, which increases coloration slightly - * but also improves contrast. + * in order to activate it and explicitly call @FT_Library_SetLcdFilter + * to enable it. + * + * A filter should have two properties: + * + * 1) It should be normalized, meaning the sum of the 5~components + * should be 256 (0x100). It is possible to go above or under this + * target sum, however: going under means tossing out contrast, going + * over means invoking clamping and thereby non-linearities that + * increase contrast somewhat at the expense of greater distortion + * and color-fringing. Contrast is better enhanced through stem + * darkening. + * + * 2) It should be color-balanced, meaning a filter `{~a, b, c, b, a~}' + * where a~+ b~=~c. It distributes the computed coverage for one + * subpixel to all subpixels equally, sacrificing some won resolution + * but drastically reducing color-fringing. Positioning improvements + * remain! Note that color-fringing can only really be minimized + * when using a color-balanced filter and alpha-blending the glyph + * onto a surface in linear space; see @FT_Render_Glyph. + * + * Regarding the form, a filter can be a `boxy' filter or a `beveled' + * filter. Boxy filters are sharper but are less forgiving of non-ideal + * gamma curves of a screen (viewing angles!), beveled filters are + * fuzzier but more tolerant. + * + * Examples: + * + * - [0x10 0x40 0x70 0x40 0x10] is beveled and neither balanced nor + * normalized. + * + * - [0x1A 0x33 0x4D 0x33 0x1A] is beveled and balanced but not + * normalized. + * + * - [0x19 0x33 0x66 0x4c 0x19] is beveled and normalized but not + * balanced. + * + * - [0x00 0x4c 0x66 0x4c 0x00] is boxily beveled and normalized but not + * balanced. + * + * - [0x00 0x55 0x56 0x55 0x00] is boxy, normalized, and almost + * balanced. + * + * - [0x08 0x4D 0x56 0x4D 0x08] is beveled, normalized and, almost + * balanced. + * + * The filter affects glyph bitmaps rendered through @FT_Render_Glyph, + * @FT_Load_Glyph, and @FT_Load_Char. It does _not_ affect the output + * of @FT_Outline_Render and @FT_Outline_Get_Bitmap. + * + * If this feature is activated, the dimensions of LCD glyph bitmaps are + * either wider or taller than the dimensions of the corresponding + * outline with regard to the pixel grid. For example, for + * @FT_RENDER_MODE_LCD, the filter adds 3~subpixels to the left, and + * 3~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. + * + * It is important to understand that linear alpha blending and gamma + * correction is critical for correctly rendering glyphs onto surfaces + * without artifacts and even more critical when subpixel rendering is + * involved. + * + * Each of the 3~alpha values (subpixels) is independently used to blend + * one color channel.

Microsoft decided to implement a backwards + * compatibility mode that employed several simple to complicated + * assumptions and tricks that modified the interpretation of the + * bytecode contained in these fonts to make them look ClearType-y + * somehow. Most (web)fonts that were released since then have come to + * rely on these hacks to render correctly, even some of Microsoft's + * flagship ClearType fonts (Calibri, Cambria, Segoe UI). + * + * The minimal subpixel hinting code (interpreter version 40) employs a + * small list of font-agnostic hacks to bludgeon non-native-ClearType + * fonts (except tricky ones[1]) into submission. It will not try to + * toggle hacks for specific fonts for performance and complexity + * reasons. The focus is on modern (web)fonts rather than legacy fonts + * that were made for black-and-white rendering. + * + * Major hacks + * + * - Any point movement on the x axis is ignored (cf. `Direct_Move' and + * `Direct_Move_X'). This has the smallest code footprint and single + * biggest effect. The ClearType way to increase resolution is + * supersampling the x axis, the FreeType way is ignoring instructions + * on the x axis, which gives the same result in the majority of + * cases. + * + * - Points are not moved post-IUP (neither on the x nor on the y axis), + * except the x component of diagonal moves post-IUP (cf. + * `Direct_Move', `Direct_Move_Y', `Move_Zp2_Point'). Post-IUP + * changes are commonly used to `fix' pixel patterns which has little + * use outside monochrome rendering. + * + * - SHPIX and DELTAP don't execute unless moving a composite on the + * y axis or moving a previously y touched point. SHPIX additionally + * denies movement on the x axis (cf. `Ins_SHPIX' and `Ins_DELTAP'). + * Both instructions are commonly used to `fix' pixel patterns for + * monochrome or Windows's GDI rendering but make little sense for + * FreeType rendering. Both can distort the outline. See [2] for + * details. + * + * - The hdmx table and modifications to phantom points are ignored. + * Bearings and advance widths remain unchanged (except rounding them + * outside the interpreter!), cf. `compute_glyph_metrics' and + * `TT_Hint_Glyph'. Letting non-native-ClearType fonts modify spacing + * might mess up spacing. + * + * Minor hacks + * + * - FLIPRGON, FLIPRGOFF, and FLIPPT don't execute post-IUP. This + * prevents dents in e.g. Arial-Regular's `D' and `G' glyphs at + * various sizes. + * + * (Post-IUP is the state after both IUP[x] and IUP[y] have been + * executed.) + * + * The best results are achieved for fonts that were from the outset + * designed with ClearType in mind, meaning they leave the x axis mostly + * alone and don't mess with the `final' outline to produce more + * pleasing pixel patterns. The harder the designer tried to produce + * very specific patterns (`superhinting') for pre-ClearType-displays, + * the worse the results. + * + * Microsoft defines a way to turn off backwards compatibility and + * interpret instructions as before (called `native ClearType')[2][3]. + * The font designer then regains full control and is responsible for + * making the font work correctly with ClearType without any + * hand-holding by the interpreter or rasterizer[4].
