Hi, i stumbled upon a problem with ttfautoninting bundled in Glyphs app.
Expected
According to specifications of ttfautohint the x Height Snapping Exceptions sholde work like this:
A list of comma separated PPEM values or value ranges at which no x height snapping shall be applied. A value range has the form value 1
-
value 2, meaning value 1 <= PPEM <= value 2. value 1 or value 2 (or both) can be missing; a missing value is replaced by the beginning or end of the whole interval of valid PPEM values, respectively (6 to 32767). Whitespace is not significant; superfluous commas are ignored, and ranges must be specified in increasing order. For example, the string"7-9, 11, 13-"
means the values 7, 8, 9, 11, 13, 14, 15, etc. Consequently, if the supplied argument is"-"
, no x height snapping takes place at all. The default is the empty string (""
), meaning no snapping exceptions.
Real
Paste or type values in input → press OK
Values saved only if there is a single value in the input. Like 10
or 2
In all other cases value is reset to default (empty).
Please help. Maybe i’m not getting something, or maybe it’s a bug.
