5 add features to the GUI
6 -> direct control over `actions'
7 -> preview similar to ftgrid
8 -> drag and drop to the application itself
9 -> autocompletion of file names with tab key
14 control `gasp' table; Adam Twardoch suggest the following:
16 1. Calculate "gaspstem", i.e. the most common thickness of horizontal
17 stems (y direction distances) for lowercase Latin letters.
18 2. If gaspstem <= 0.03 * upm, apply gasp symmetric smoothing across the
19 entire range (rangeMaxPPEM 0xFFFF, value 15)
20 3. Else, calculate gaspthreshold as follows:
21 ceil(1.33 * upm / gaspstem) - 1
22 4. Apply no symmetric smoothing up to the gaspthreshold ppem (rangeMaxPPEM
23 gaspthreshold, value 7), and apply symmetric smoothing above.
25 In addition, ttfautohint should provide a commandline parameter that
26 allows the user to override the automatic logic. If that parameter = 0,
27 then gasp value 15 should be applied across the entire range. If the
28 parameter > 0, then up to that parameter value the gasp value 7 should be
29 applied, and gasp value 15 should be applied above.
31 create a separate blue zone class for `i' and `j':
32 . if the values differ more than a given threshold, handle them
34 . otherwise, unify them with `f' and friends.
36 control the characters used for blue zones
39 user-defined blue zones?
42 control the width of blue zones
44 add control over character ranges which define a script; in particular, add
47 handle normal and bold fonts differently; cf. Infinality patches;
48 this should help avoid filling of bowls (like in `e') for bold shapes.
50 control the minimum stem width
52 try to `embolden' fonts at small sizes to avoid drop-outs; cf. Infinality
55 implement `x-height-snapping-exceptions'
57 improve `pre-hinting' by making the used PPEM value configurable
59 allow hinting of single glyphs, using a config file which holds the global
62 better handling of `incomplete' fonts (this is, fonts which lack the minimum
63 set of glyphs necessary to determine the blue zones)
69 make ttfautohint a filter
71 reject fonts which are `hopeless' (for example, `Lipstick')
73 reduce memory consumption by using 16bit data types in large arrays if 32bit
76 correctly set `lowestRecPPEM' field in `head'
80 apply hinting in x direction also?
81 -> warper: shifting with and without scaling
82 -> `standard' autofit hinting
84 add a config and/or command file for batch handling
86 warn against overwrite of output file?
88 reduce output size of option -p:
89 1. compare outline rendered at EM value with unhinted outline
90 2. pre-hint only if 1. differs more than given threshold (default 0.5%?)
92 make it possible to hint fonts which aren't alphabetic at all, for example,
93 icons; to do so, provide means to skip the global feature analysis
95 better control -i output
97 allow processing of multiple files by using globs as in the Midnight
100 allow composite fonts already processed by ttfautohint to be processed
103 make ttfautohint remember options:
104 1. collect md5 checksums in a `~/.ttfautohint_history' file so that fonts
105 can be re-processed easily, using the same parameters
106 2. if fonts already processed by ttfautohint can be re-processed (which
107 isn't possible yet), parse the `version' string for parameters
113 add CJK autohinting module
114 add Hebrew autohinting module
116 instead of emitting bytecode, write the hints as a VTT or FontLab script
118 Windows/Mac installer
124 testing with Windows and Apple font checkers
126 man page for ttfautohint library
130 add help2man script so that parallel builds always work
