Autohinting Options
You can customize the autohinting algorithms using the Type 1 page of the
Options dialog box (Tools > Options...):
Width limits
Declares the minimum and maximum width of hints that the
autohinting algorithm is allowed to create.
Min. length
Declares the minimum length of the nearest vertical (or
nearest horizontal) vectors (or curve control vectors) that can
be a candidate for building a hint
Minimal length/
width aspect ratio
Declares a critical correlation between the width of a
candidate for the hint and the length of the vector that builds
that candidate.
Remove all
existing hints
before autohinting
Allows you to remove all existing hints before autohinting the
glyph. If this option is switched off new hints will be added to
the existing hint set. Of course, a hint substitution program
will be built.
Note that all values are set for a 1000 UPM font and are automatically
scaled by FontLab according to the real UPM value.
