3 * New option `--dehint' to strip off all hints without generating new hints.
4 This option is intended for testing purposes.
6 * Minor fixes to the created bytecode for compatibility.
8 * Minor GUI improvements.
13 * New option `--windows-compatibility' which adds two artificial blue zones
14 at vertical positions given by `usWinAscent' and `usWinDescent'. This
15 helps ttfautohint's hinting algorithm reduce the possibility of clipping
16 if those two values are very tight.
18 * Implement option `--x-height-snapping-exceptions', making ttfautohint
19 avoid x-height snapping for selected PPEM values. Useful in combination
20 with `--windows-compatibility'.
22 * Minor fixes to the created bytecode for compatibility and robustness.
27 * New option `--components' to treat components of composite glyphs
28 separately. This greatly reduces the bytecode size.
30 I'm waiting for reports whether this option works for most fonts; in case
31 this is true I'm inverting the option, making it the default (and the old
34 * Full support of TTCs, this is, all subfonts get auto-hinted now.
36 * The upper limit of the `--increase-x-height' option has been removed.
38 * Drag-and-drop support in the GUI.
40 * The TTY version of ttfautohint now acts like a (Unix) filter, this is, it
41 accepts stdin and stdout as input and output, respectively.
43 * Less memory consumption.
48 * A serious bug in the created bytecode has been fixed, causing incorrect
54 * A new, `strong' routine to handle stem widths and positions has been
55 added, to be selected with the `--strong-stem-width' command line option.
56 If it is active, stem widths and positions are snapped to the grid as much
57 as possible. This algorithm is useful for GDI ClearType support.
59 * A new command line option `--debug' (not available for ttfautohintGUI) to
60 print very detailed debugging information.
65 * The created bytecode has been reduced in size, making it approx. 20%
68 * New option `--symbol' to use standard stem height and width values instead
69 of using character `o' (which may be missing). Use this option for symbol
72 * More documentation (in text, HTML, and PDF format). It's still
75 * Option `--ignore-permissions' has been renamed to `--ignore-restrictions'.
76 The short form is still `-i'.
78 * Defaults for various parameters have been set to more sensible values:
80 hinting-range-max: 50 (was 1000)
81 hinting-limit: 200 (was 1000)
83 * Option `--increase-x-height' now has a mandatory argument (in the range
84 6-20 or value 0 to disable it, default value is 14).
89 * Implement option `-x' to increase the x height of the font for small PPEM
90 values by rounding up far more often then rounding down.
92 * Add option `-G N' to switch off hinting completely above value N.
94 * ttfautohint now appends version information and the used parameters to the
95 `Version' field(s) in the `name' table. This can be suppressed with
101 * A GUI has been added, using the Qt framework. The binary is called
107 * The improved handling of composite glyphs in 0.6 was buggy under certain
108 circumstances, making ttfautohint crash and FontValidator complain.
110 * Dropout handling has been activated.
115 * Improved handling of composite glyphs.
117 * Implement option `-p' to pre-hint glyphs with original hints before
118 conversion takes place.
120 * Don't add a DSIG table if there is none in the input font.
122 * Human-readable error messages instead of hexadecimal error codes.
124 * Better tests (both at runtime and compile time) to reject too old FreeType
130 * Rendering on iOS is now expected to give good results.
132 * No bad rendering at very large PPEM values.
137 * The bytecode has been changed to `create' twilight points. This should
138 avoid rendering artifacts on some platforms.
143 * Fix font generation; sometimes the `glyf' table was one byte too short,
144 making the font invalid.
149 * Fix bytecode bugs which prevented correct rendering on some platforms.
