4 explicitly check for new functionality of `FT_Sfnt_Table_Info', both at
7 write a platform-independent GUI
8 -> direct control over `actions'
9 -> preview similar to ftgrid
12 important improvements
13 ----------------------
18 control `gasp' table; Adam Twardoch suggest the following:
20 1. Calculate "gaspstem", i.e. the most common thickness of horizontal
21 stems (y direction distances) for lowercase Latin letters.
22 2. If gaspstem <= 0.03 * upm, apply gasp symmetric smoothing across the
23 entire range (rangeMaxPPEM 0xFFFF, value 15)
24 3. Else, calculate gaspthreshold as follows:
25 ceil(1.33 * upm / gaspstem) - 1
26 4. Apply no symmetric smoothing up to the gaspthreshold ppem (rangeMaxPPEM
27 gaspthreshold, value 7), and apply symmetric smoothing above.
29 In addition, ttfautohint should provide a commandline parameter that
30 allows the user to override the automatic logic. If that parameter = 0,
31 then gasp value 15 should be applied across the entire range. If the
32 parameter > 0, then up to that parameter value the gasp value 7 should be
33 applied, and gasp value 15 should be applied above.
35 disable hinting at large ppem values (> ~2000) to avoid numeric overflows
39 control activation threshold of blue zone widths
41 control the width of blue zones
43 handle normal and bold fonts differently; cf. Infinality patches
45 control the minimum stem width
47 try to `embolden' fonts at small sizes to avoid drop-outs; cf. Infinality
50 implement `x-height-snapping-exceptions' and `pre-hinting'
52 allow hinting of single glyphs, using a config file which holds the global
55 better handling of `incomplete' fonts (this is, fonts which lack the minimum
56 set of glyphs necessary to determine the blue zones)
62 make FreeType error codes human-readable
64 correctly set `modified' field in `head'
66 correctly set `lowestRecPPEM' field in `head'
68 set dropout mode et al.
70 apply hinting in x direction also?
71 -> warper: shifting with and without scaling
72 -> `standard' autofit hinting
74 try to reduce size of hints by handling strong points separately
76 add a config and/or command file for batch handling
78 make creation of DSIG table optional
84 add CJK autohinting module
85 add Hebrew autohinting module
87 instead of emitting bytecode, write the hints as a VTT or FontLab script
95 testing with Windows font checker
