- The font in question (Nunito) has values 705 and 713 for the - reference and overshoot values, respectively, of the first blue - zone. Blue zone 2, however, has value 710 for both the reference - and overshoot. At 12ppem, reference and overshoot of blue zone 0 - becomes 8px, while blue zone 2 becomes 9px. - - A peculiarity of this font is that the tops of isolated vertical - stems like `N' have a slight overshoot also. The auto-hinter tries - to find the nearest blue zone using the *original* coordinates. For - vertical stems, this is value 713. For normal horizontal tops like - in character `E', this is value 710. Since value 713 is mapped to - 8px but value 710 to 9px, `N' and similar characters are one pixel - higher than `E', which looks very bad. - - This commit sanitizes blue zones to avoid such a behaviour. - - * src/autofit/aflatin.c (af_latin_sort_blue): New function. - (af_latin_metrics_init_blues): Sort blue values and remove overlaps. - -2017-02-12 Alexei Podtelezhnikov - - * src/smooth/ftgrays.c (gray_sweep): Improve code. - -2017-02-06 Werner Lemberg - - [truetype] Implement `VVAR' table support. - - * src/truetype/ttgxvar.h (GX_HVarTable): Renamed to... - (GX_HVVarTable): ...This. - (GX_Blend): Add fields for `VVAR' table handling. - Other minor updates. - - * src/truetype/ttgxvar.c (ft_var_load_hvar): Renamed to... - (ft_var_load_hvvar): ...This. - Handle VVAR loading also (controlled by an additional parameter). - (tt_hadvance_adjust): Renamed to... - (tt_hvadvance_adjust): ...This. - Handle application of advance height also (controlled by an - additional parameter). - (tt_hadvance_adjust, tt_vadvance_adjust): Wrappers for - `tt_hvadvance_adjust'. - - * src/truetype/ttdriver.c (tt_service_metrics_variations): Updated. - -2017-02-05 Werner Lemberg - - [autofit] Use better blue zone characters for lowercase latin. - - The number of lowercase characters for computing the top flat blue - zone value was too small (in most cases only `x' and `z').

IMPORTANT CHANGES + + - As a GSoC project, Ewald Hew extended the new (Adobe) CFF engine + to handle Type 1 fonts also, thus greatly improving the + rendering of this format. This is the new default. The old + engine is still available if the configuration macro + `T1_CONFIG_OPTION_OLD_ENGINE' gets defined; using the + `hinting-engine' property of the `type1' driver module you can + then switch between the two engines. + + - A new function, `FT_Set_Named_Instance', can be used to set or + change the current named instance. + + - Starting with this FreeType version, resetting variation + coordinates will return to the currently selected named + instance. Previously, FreeType returned to the base font (i.e., + no instance set). + + + III. MISCELLANEOUS + + - The `face_flags' field of the `FT_Face' structure has a new bit, + `FT_FACE_FLAG_VARIATION', which is set if a variation font has + been altered with `FT_Set_MM_Design_Coordinates', + `FT_Set_Var_Design_Coordinates', or + `FT_Set_Var_Blend_Coordinates'. + + - If the current face is a named instance, the new macro + `FT_IS_NAMED_INSTANCE' returns true. + + - `FT_IS_VARIATION' is a new macro that returns true whenever a + face object has been altered by `FT_Set_MM_Design_Coordinates', + `FT_Set_Var_Design_Coordinates', or + `FT_Set_Var_Blend_Coordinates'. + + - Changing the design coordinates of a variation font with + `FT_Set_Var_Design_Coordinates' or + `FT_Set_Var_Blend_Coordinates' does not influence the named + instance index value (only `FT_Set_Named_Instance' does that). + + - Special PostScript names for named instances are only returned + if the named instance is set with `FT_Set_Named_Instance' (and + the font has corresponding entries in its `fvar' table). If + `FT_IS_VARIATION' returns true, the algorithmically derived + PostScript name is provided, not looking up special entries for + named instances. + + - A new function `FT_Done_MM_Var' is provided to free the memory + returned in a call to `FT_Get_MM_Var'. + + - On platforms using the `configure' script, the installed + `ftoption.h' file now correctly reflects configuration options + like `--with-harfbuzz'. + + - Better support to build FreeType as a DLL on Windows using + Visual C. + + - All data specific to driver modules is now collected in a single + file, `FT_DRIVER_H'. Consequently, the macros + `FT_AUTOHINTER_H', `FT_CFF_DRIVER_H', `FT_TRUETYPE_DRIVER_H', + and `FT_PCF_DRIVER_H' still work but are deprecated. + + - Some fuzzer fixes to better reject malformed fonts. + + - The `ftbench' demo program has a new test for opening a new face + and loading some glyphs. + + - The `ftbench' demo program has a new option `-j' to specify the + last glyph index to be used in the tests. + + - The `ftgrid' demo program has a new option `-n' to suppress + display of named instances of variation fonts. + + - The `ttdebug' demo program can now show a stack trace (key `K') + and switch between hexadecimal and decimal display of integers + (key `I'). + + +====================================================================== + +CHANGES BETWEEN 2.8 and 2.8.1 + + I. IMPORTANT BUG FIXES + + - B/W hinting of TrueType fonts didn't work properly if + interpreter version 38 or 40 was selected. + + - Some severe problems within the handling of TrueType Variation + Fonts were found and fixed. + + - Function `FT_Set_Var_Design_Coordinates' didn't correctly handle + the case with less input coordinates than axes. + + + II. IMPORTANT CHANGES + + - By default, FreeType now offers high quality LCD-optimized + output without resorting to ClearType techniques of resolution + tripling and filtering. In this method, called Harmony, each + color channel is generated separately after shifting the glyph + outline, capitalizing on the fact that the color grids on LCD + panels are shifted by a third of a pixel. This output is + indistinguishable from ClearType with a light 3-tap filter. + + + III. MISCELLANEOUS + + - Using the new function `FT_Get_Var_Axis_Flags', an application + can access the `flags' field of a variation axis (introduced in + OpenType version 1.8.2) + + - More sanity checks. + + - The internal representation of buffers for LCD rendering has + changed (to be more precise, the amount of padding gets computed + differently). Applications that use the FreeType API are not + affected. + + - To reset all design axis values of a variation font to its + default values you can now say + + error = FT_Set_Var_Design_Coordinates( face, 0, NULL ); + + This also works with functions `FT_Set_MM_Design_Coordinates' + and `FT_Set_MM_Blend_Coordinates'. + + - FreeType now synthesizes a missing Unicode cmap for (older) + TrueType fonts also if glyph names are available. + + - FreeType has improved handling of BDF fonts without the + `POINT_SIZE', `RESOLUTION_X', or `RESOLUTION_Y' properties; the + library now uses the values of the `SIZE' keyword if they are + missing. Previously, `SIZE' was completely ignored, and + FreeType used heuristic values instead. + + - Multiple calls to `FT_Bitmap_Convert' do work now as advertised. + Previously, they failed with an assertion error if there was an + empty bitmap between non-empty ones. + + - The warping option has moved from `light' to `normal' hinting + where it replaces the original hinting algorithm. The `light' + mode is now always void of any hinting in x-direction. + + - 16bit compiler support is now officially ended.

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://www.beatstamm.com/typography/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://www.beatstamm.com/typography/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://www.beatstamm.com/typography/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://www.beatstamm.com/typography/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.

This lead to what GDI calls - * `natural widths' ClearType, see - * http://www.beatstamm.com/typography/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://www.beatstamm.com/typography/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://www.beatstamm.com/typography/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_ _Backwards_ _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://www.beatstamm.com/typography/RTRCh4.htm#Sec1 and - * http://www.microsoft.com/typography/cleartype/truetypecleartype.aspx. - * This technique is not to be confused with ClearType compatible - * widths.

This could be worked around in backwards - * compatibility mode. - * - * _Native_ _ClearType_ _Mode_ - * - * (Not to be confused with `natural widths'.)
