OpenType Layout Options
OpenType Layout Page of the Preferences Dialog
These options are used to customize the OpenType font features generating
process:
Remove all features
If this option is checked, all features of the source
OpenType font will be ignored. This may be useful
when one wants to convert OpenType TT font to the
traditional TrueType font. This option is off by default.
It is ignored if the Perform optimal conversion
method if possible
option is on
Add standard features
if possible
If this option is checked, autogeneration of basic
OpenType features is possible. TransType Pro
automatically generates “liga”, “ccmp”, “frac”, “kern”,
and “ordn” OpenType features if glyphs that can be
used in these features are present in the font. This
feature works on converting of Latin fonts only to both
TT and PS OpenType formats. This option is ignored if
the Perform optimal conversion method if
possible
option is on
Convert Apple morph
features to OT features
This option lets you control the conversion of special
metamorphosis tables in AAT fonts to OpenType
features. If this option is checked, TransType Pro will
try to convert those tables to the following supported
OpenType features: rlig, liga, dlig, hlig, alig, isol, smcp,
vrt2, vkna, tnum, sups, subs, frac, zero, ornm, trad,
tnam, smpl, jp78, jp83, jp90, onum, pwid, hwid, fwid,
ccmp. Note that not all AAT features can be
converted
Write 'kern' table
If this option is checked, TransType Pro will write the
plain kerning table when generating an OpenType
font. This option is normally on
Write 'kern' feature
If this option is checked, TransType Pro will generate
and write the 'kern' OpenType feature. This option is
on by default.
